TRANSFORMER UFO OVER LONDON, UK - PART 1: 28 Nov 08 ,10:49 pm-P 1/2

Part 1 of 2 On Friday, 28th November, 2008, during the daytime, I had this sharp radio-zumbing in my ears, (high and low); then at night (10.49 pm), just before going to bed, I decided to look through the window and saw this immensely bright, luminous object, just static there to begin with, at very low altitude and completely silent. It was very cold, the sky had shining stars and therefore was quite clear, with a few dispersed clouds. I grabbed my camera and began filming this exciting observation, just before the object began to move away. London, UK Comment from KP/friend: "Note the periodic double pulse of light given off by this object, a sequence that I have not seen before on any conventional aircraft: this footage has been analyzed and it has been determined that this is a genuinely unidentified form; that is, not a commonplace aircraft and not anything of an astronomical nature either: This leads me to conclude that what was filmed could be a secret, black budget, military craft - or something infinitely stranger than that...ET perhaps?!?" ps; haters are not welcome.

Testing a Transformer - How To Accurately Test A Transformer

!±8± Testing a Transformer - How To Accurately Test A Transformer

There is two types of transformers in the market- linear transformer and switch mode power transformer. The transformers design is different. Sometimes it is just referred as ac transformer. Linear transformer mostly used in radio, project kits, VCD and etc while switch mode transformer can be found in Monitor, Tv, Fax and so on.

A transformer consists of two or more coils wound on the same core. For power transformers, the core material is usually iron. For a radio-frequency transformer, the core material is usually ferrite or air. The basic property of a transformer is to change AC voltage. A transformer cannot change direct current voltage. A step down transformer has a lower AC output voltage at its secondary winding than the AC input voltage to its primary winding. Conversely, a step up transformer has a higher secondary than primary voltage. The transformer laminations or coating of shellac, enamel or varnish is to insulate adjacent turns from shorts between winding. I will not go too details about how transformer work and transformer calculation as you can read more details from most electrical and electronic transformers books.

How to test transformers: Transformer failures are relatively rare in most electronic equipment, compared with other components. If too much current goes through a coil or winding, the winding heats up and can either open up completely, or the insulation between turns of wire can break down, causing the coil to be partly or completely shorted.

Just like a coil, you can check continuity of any primary or secondary transformer winding. The actual value of DC resistance you read is rather meaningless, but at least you will know whether a winding is open. Checking linear transformer is quite straight forward. Apply the ac voltage to the primary winding and expect output voltage at the secondary side. No or low output voltage means the transformer winding has open or shorted winding. Look for any evidence of overheating, such as darkened or blackened areas or a burnt smell.

About how to test a power transformer-it is a little bit complicated. You cannot apply ac voltage to the equipment and expect the desire output at the secondary side without connect to load otherwise over voltage will happen (because you have removed all the secondary load) and will blow the power section which consist of power fet, pwm ic and etc. Switch mode power supply are designed to run with load while linear transformer can be test without load.

The best way to test a switch mode power transformer is first remove it from the board. Check only the primary winding as secondary winding failures are exceedingly rare. How do we know which one is the primary winding? Trace from the big filter cap the positive pin to see where the circuit goes. It will go to one of the pin of the transformer. Then look for the power fet middle pin which is the Drain and it will lead to another pin of the transformer. This two pins is the primary winding of the transformer. Checking the resistance of the primary winding only can reveal whether it is open but it cannot check if it has developed a shorted winding. Only by using a ringer test you will know if it shorted or not. A shorted turn in the primary winding can cause the power section to blow.

The cheapest ringer tester that i came across is Dick Smith LOPT METER or flyback tester. Just connect the probes to the primary winding and the result are instantly seen from the Led bar graph. 4-8 bar represent a good winding, 1-2 bar represent partial short and if the led goes off means there is a heavy short in the winding. Besides checking the transformer it can be use to check B+ COIL, horizontal yoke coil and flyback primary winding and ballast (choke).

The expensive ringer tester is from sencore equipment. Sencore LC102 and LC103C besides checking capacitor it also have the capability to check all kind of winding. Whether it is a low voltage transformer, high voltage transformer, current transformer, pulse transformer, electric transformer, custom transformer this equipment will be able to check and test it.

If you do not wish to invest on this tester you may use a light bulb to check it. Remove one of the primary winding pin and connect a 60 watt light bulb. One end to the circuit while the other to the transformer pin. If the bulb light and didn't goes off suspect a shorted winding and if the light goes off, the winding is ok.

Transformer repair is not easy and it require a good skill to do it. Most of the transformer repairer preferred to rewind bigger winding such as fan, car alternator and starter. Switch mode power transformer is a little bit difficult to rewind because of the small size and low price.

no BS 3 in 1 solid state charger/rejuvenator/pulser

"simplified version" circuit drawing - www.magneticitist.com it seems too many people dont understand how easy it is to build a DIY circuit that achieves the same results as a similar circuit that can be bought online for hundreds or even thousands of dollars. this is an example of a circuit made entirely of salvaged parts that does what expensive battery charger and rejuvenaters do... it of course is not heavy duty enough to charge a super large battery bank with in a reasonable amount of time, but thats just because i didn't add any extra coils, which would be simple. i have one air core coil with 3 windings. 2 transistors total. the mechanical aspect of the cap pulser is being run entirely from small inductive spikes that the back end of the charging circuit doesn't even notice missing. the coil's windings are using a gauge and turn count that permits a decent amount of current at a decent voltage.. its that simple... so i dont have an insane number of turns, that would increase my voltage and decrease my current too much, unless of course this was offset by a much higher draw. instead of having insane windings, i just switch my pulse over to a 12v adapter transformer that will give me the high voltage low current i want for it's intended plate cleansing purpose. this circuit was designed to output only so much, so if i wanted to get a much bigger bang from my cap bank i can just add bigger caps, which will just end up slowing the pulse rate slightly unless i ...

Interview with Comic Book Professional Barry Kitson

!±8± Interview with Comic Book Professional Barry Kitson

What do Batgirl, L.E.G.I.O.N., Superman, Batman, Azrael, JLA, Barry Allen and Hal Jordan, Titans, Avengers/Thunderbolts and Empire have in common?

Artist extraordinaire Barry Kitson, that's what. Barry has pencilled them all. Now, with a DC exclusive contract, the forthcoming JSA: Strange Adventures (previously known as Lord Dynamo) and the recently announced Legion of Super-Heroes relaunch with long-time collaborater Mark Waid, Barry's in for a busy year!

Nevertheless, he kindly took time out to chat with PaperbackReader about how he got started, latest projects and everything in between...

PaperbackReader: What lead you to comics? Was it something you always wanted to do or was it just supposed to be a pit-stop on the way to something else?

Barry Kitson: No, it was literally all I ever wanted to do from when I was about 6 years old. Somebody showed me some US comics when I was about that age, and basically all I wanted to do from then on was to draw comics. I had a few years in my teens when I wanted to be a rock star, but that didn't quite work out.

PBR: Your first work was for Marvel UK; how did you manage to land that?

BK: That was just being in the right place at the right time really. I'd been down to Marvel with some samples, and they'd basically said they quite liked them but they wanted me to have something published before they'd give me any work. I said how will I get something published if nobody gives me any work until I've got something published? That was just the accepted practice back then I think.

PBR: And it's more or less the same now, isn't it?

BK: Yeah, but what they did say was that they'd give me a script to work on just so I could show them what I could do, but they never actually sent me it. When I rang up to find out what was going on, they said the editor I'd seen was no longer there and I'd better come down and see the new guy.

PBR: So you had to go back and do it all again?

BK: Well I went back down and luckily the first time I'd been there it had been someone's leaving do, and I'd gone along to that and got to know everybody there through the evening, so when I walked in this time everyone was going, "Hello, Barry, nice to see you again," and the new editor, who hadn't been there at all, thought 'Oh well everybody knows him, I'd better give him some work'. He said that they were looking for somebody to draw a Spider-Man strip they were going to do for a few weeks, he gave me a script and asked me to go away, draw a page, and bring it back the next day, so I did. He liked it and gave me the job.

PBR: That was back in the UK's Spider-Man Weekly?

BK: Yeah, for four weeks they ran a story that originated in the UK by Mike Collins. He wrote all four weeks and drew two. I drew the other two, and Mark Farmer inked all four. After that I basically worked at Marvel for maybe a year or so. I did Transformers, a strip called Space Thieves as a back-up in Captain Britain, basically anything. Really I was just very, very lucky that there was stuff out there so I could learn the trade.

PBR: As you say, it was the right place at the right time. And you worked on 2000A.D. [a British science-fiction based weekly comic] as well, on Grant Morrison's script?

BK: Well Grant wrote the first script I did for them, which was one of the 'Future Shocks', then basically I was working with Alan Grant on Dredd and Judge Anderson after that.

PBR: So a lot of big names before they made it in the US really?

BK: Yes, I mean at the time they were just beginning. I think that that was some of Grant's first work as well, and Alan and John Wagner were, I think, just about to begin their run on Detective Comics.

PBR: Grant Morrison has a reputation for being very innovative, and to 'think outside the box' in his storytelling. Was he like that even back then?

BK: It's very difficult for me to say, really. I didn't meet him at all back then.

PBR: So you were just working from the scripts?

BK: Yeah. There was kind of a community of artist and writers in London but that was about it. Most of the rest of the people working in the UK outside London didn't really bump into each other much in those days.

PBR: Was it long after that you landed your first DC work in the US?

BK: I probably worked on 2000A.D. for about a year. Then - and this was really through Alan - DC were looking for somebody to draw Batgirl and at that time Alan was writing Detective; he suggested my name to Denny O'Neil who was editing the book, and he gave me a call one night and asked me if I'd be interested in doing Batgirl and I said 'yes'. I got all excited and put the phone down and then realised that I hadn't actually asked how much they were going to pay me! But that was like a dream come true for me, working for a US comic company was what I'd always wanted to do.

PBR: That was the Batgirl Special, released shortly before The Killing Joke?. Were you aware at the time that it was going to be the last real Batgirl story?

BK: Not specifically. I knew that something was going to happen to the character, and so DC wanted this one-off, but they wouldn't tell me what it was.

PBR: And after that?

BK: I did a Legion of Super-Heroes annual and a Catwoman strip for Action Comics when it was weekly, then after both of those I was given a choice between doing the Catwoman mini they wanted to do and L.E.G.I.O.N. I'd always been a fan of the Legion and science fiction stuff, so I went that way.

PBR: And you stayed on there for about five years?

BK: I had a six-month break when I went and did some Wolverine issues and some Wildcards stuff over at Marvel, then I came back and did some more L.E.G.I.O.N. I think it was two years, then a break, then another two and a half years.

PBR: On the later run at least, you're credited as co-plotter as well as pencils. Was that a natural evolution for you?

BK: I guess you could say it was. When Alan decided he was going to move on he suggested that I was capable of writing it myself. I did that for a few issues, but I actually kind of missed the collaborative side of things so I stayed on co-plotting and Mark Waid came on board. That was when we met and we've enjoyed working with each other ever since.

PBR: You've done a number of projects together since then.

BK: We have. We've got a very good working relationship where we give each other a push and shove both ways; he lets me tinker with the story and I show him the work as I do it. If I'm planning a scene and he thinks that I'm not handling it in quite the best way, he'll give me a call and let me know, ask me if there's any way that I can do it differently. I really like that; it's half the fun, really.

PBR: And after your second stint on L.E.G.I.O.N came Adventures of Superman?

BK: That's right, I went on to Adventures of Superman after L.E.G.I.O.N and I was doing Shadow of the Bat as well.

PBR: Again, with Alan Grant.

BK: Yes, and then Azrael was kind of in the wings to do at some point. I don't actually quite know why, because it doesn't really seem to happen like that anymore, but everything seemed to be very planned out and you knew what was going on.

PBR: And you launched the regular series of Azrael, and stayed on that for a while with Denny O'Neil as the writer?

BK: I stayed on Azrael for two years, yes, with Denny writing and with Archie Goodwin as the editor, which was a real pleasure.

PBR: They're both really legends in the industry. Was it easy to work with them?

BK: Working with Denny was a bit different for me, because Denny doesn't like to collaborate a great deal with the artist. He likes to just write it, and that's his part done, so it was a big change from what I was used to. And working for Archie was one of the nicest things that could happen to anybody in the business.

PBR: So you stayed on Azrael for two years; was JLA: Year One next?

BK: Pretty much, but even back then Mark and I were talking about doing Empire. We kind of approached Wildstorm, and they were interested in doing it. DC basically asked us what it would take for us to keep with them rather than going off and doing that, and we proposed 'JLA: Year One'.

PBR: I guess it was a dream project really, because it's really all the big DC characters.

BK: Absolutely. It was childhood wish-fulfilment., really, for me. Plus we got to drag in everybody else - Doom Patrol, and all the other characters that I'd always wanted to draw.

PBR: Again, that was very much a collaboration between you and Mark Waid. Wasn't Brian Augustyn was on that as well?

BK: Yes, he was kind of working more with Mark and then I'd have to deal with the two of them.

PBR: That must have been pretty well received, because it wasn't long after that that The Brave and the Bold was announced, a mini series chronicling the relationship between Hal Jordan (Green Lantern) and Barry Allen (the Flash).

BK: That's right. It was kind of a case of "what do you want to do now?"

PBR: They really wanted to keep you two around, didn't they?

BK: I guess so. DC has always treated me very well.

PBR: I was looking at The Brave and the Bold, and a lot of the way the books were designed is very much a homage to the old silver age comics.

BK: That's what we were trying to do, really. We were trying to tell the story of Hal and Barry's friendship, and kind of stylize it to the actual comics that were around in the period they were set, which is why #4, which was a very Neal Adams-ish one-

PBR: - the one with Green Arrow in it?

BK: That's right. Tom Grindberg drew that and I just inked that one, as he's got a kind of Neal Adams style that I don't have.

PBR: And I guess that it was not long after that Gorilla Comics and Empire happened?

BK: Yes, I suppose it was.

PBR: Tell me a bit about Gorilla. How did that come about?

BK: The idea was that a whole bunch of us would get together, and make some comics and have some creative say, and see what we could do - try and do something interesting. The unfortunate side of it was that the business side of things didn't work out; we went from having backing and funding to 'you've got to pay for the printing of this yourself' which I certainly couldn't afford. It was hard. I really admire Kurt [Busiek], Stuart [Immonen], Karl [Kesel] and Tom [Grummet] because they did carry on through, but I'm very much a pragmatist. If we were selling as many as we were selling on Empire and we weren't making any money it seemed kind of pointless - like you're in a hole but you keep digging.

PBR: Sure. And it was just two issues of Empire that got released?

BK: Yes, two issues. We were hoping we'd keep going, but you have to wait and see what the economics were. Unfortunately, the economics were such that what would be a good selling book for a major company, with all the discounts they get at the printers', and would make a profit for a big company just doesn't make a profit for a small one. And another part of the trouble was because we thought we had funding, we said that we wanted the best paper, we wanted to pay the colorists more than they were getting anywhere else at the time, we were including 24 or 25 pages of story per issue instead of 22...

PBR: And I guess that cuts down on your advertising revenue.

BK: Yes and the way to economise was we put less story pages in, or we didn't use such good paper, and we just decided that we'd rather wait until we could afford to do it as it was Mark bankrolled the whole operation - for which the rest of us on the book were more than grateful!

PBR: Rather than put out something you're not entirely happy with?

BK: Absolutely. Luckily at the time DC said they liked the book and were interested in picking it up, so that's what we went for.

PBR: It took a couple of years for it to come out at DC, though.

BK: The thing was, because of what happened with Gorilla, we'd taken on other work and it became a case of when can we sit down and do this. In a lot of ways, it worked out for the betterment of the book because it gave us a chance to talk through it. We continued to talk about it over the years, and we kept throwing ideas in and the story would keep changing.

PBR: Empire is quite a violent book, and obviously September 11th happened between the Gorilla and DC issues; did that have any effect on the story?

BK: I don't think it had any conscious effect though I'm sure on a subconscious level 9-11 probably affected everyone's world view. If anything I think it may have brought what we trying to say about how ugly violence and power seeking is into sharper focus, but we didn't hold back because of it.

PBR: And you've had pretty favourable reviews every where, really.

BK: Yes, it seems to have been very well accepted by everybody.

PBR: And is DC happy with it?

BK: Yes, they seem to be.

PBR: Happy enough to give you a second series?

BK: I certainly hope so! Mark and I have got plans for at least a hundred issues of Empire.

PBR: That's plotting in advance!

BK: That's just from talking about it over the years. It's such a big canvas...

PBR: It is. As a reader, one of the joys of the series is that nobody's ever safe; anything can happen.

BK: That was part of the point. What we were trying to do with all of it was to play with all of the preconceptions that readers have about superhero comics; that characters won't die, they'll always wear the same clothes, that the good guys are the good guys and the bad guys are the bad guys. The idea was to make it fun because people wouldn't know what was going to happen next, even when they thought they might think they did.

PBR: Stepping back, before Empire ran at DC you were working on the Titans. At the time, I guess the book was kind of dying a critical death to some extent; the storylines weren't being particularly well received almost from the beginning of that run. When you're working on a book that isn't a big hit with fans, does it affect your enthusiasm for your work?

BK: Well, the Titans thing was kind of pear-shaped from the start really. I was asked if I wanted to write and draw it, so the idea was I could kind of try to put it right, but when I actually came on board the editor and writer had patched things up so I came on just as the artist. Then I found out that the writer, Jay Faerber, hadn't been writing the kind of stories that he really wanted to write; but by then I was on the book, and I was sympathising with him and we both kind of stuck with a book we couldn't steer the way we had hoped. By the time that Jay decided he'd had enough and Tom Peyer was coming on board, DC had decided the whole thing was going to be re-jigged anyway. It never became the book I really wanted it to become and I never got the chance to do the things I wanted to do. In hindsight, I probably shouldn't have started on it when I found out that I wasn't going to be getting the chance to change things as I'd hoped, but also, Andy Helfer the editor was a friend and you don't like to let anybody down. It wasn't the happiest time because I like the Titans a lot as characters and I looked forward to drawing it, and never really getting the chance to do with them as I liked wasn't great. Its just one of those things, I suppose. Hopefully I'll have learned some lessons from what happened!

PBR: Okay, just bringing it up to date, you signed a three year exclusive with DC early this year?

BK: That's right. It came about when I was working for Marvel as well, on Avengers/Thunderbolts.

PBR: How many issues of that did you do in the end?

BK: I completed issue one, did the breakdowns for number two and pencilled and inked all the covers. The schedules between the two companies just went kind of haywire; I would never intend to leave a project before I completed it but it just wasn't physically possible to do it all the work DC and Marvel wanted from me in the time available and something had to give. DC had some long term things they wanted me to do and they made me an offer I couldn't refuse. I agonized over what to do for a long time, but really there was only one choice to make. I would like to say how understanding the editorial team at Marvel were (Tom Brevoort and Any Smith) which I really appreciated and I really hope I get a chance to make it up to them someday! At least I got to draw one issue. It was the first chance I'd had to work with Kurt [Busiek] since Gorilla, and I got to meet Fabian [Nicieza] as well. It's a shame but it just couldn't be avoided. Ironically Tom Grummet, another Gorilla artist, finished it up. I took over Adventures of Superman from him and he's taken over that from me.

PBR: Swings and roundabouts.

BK: Exactly.

PBR: And what kind of things did DC offer?

BK: Well one of them was the JSA book I'm working on at the moment, Lord Dynamo, which is nearly 200 pages long.

PBR: And what format is that coming out in?

BK: I think six thirty page books.

PBR: And it's set in World War II?

BK: It is, yes, so it's kind of like a JLA: Year One thing again for me but this time I get to draw all the original characters.

PBR: Again, a bit of a dream project.

BK: Yeah, it's great; I'm having a lot of fun. It's really the first kind of period piece that I've done so it's giving me a chance to use a lot of references and get really stuck into old architecture and engineering and things.

PBR: And are you writing that series?

BK: No, it's written by Kevin J Anderson. He's a very well respected science fiction author with several best-sellers to his name

PBR: Okay. What do you have lined up after that? I read an interview with Mark Waid that hinted that there might be something else for the two of you coming up?

BK: Yes, Mark and I will definitely be doing something after that. J

PBR: I know that there are constantly rumours on various message boards about either Legion of Super-Heroes or L.E.G.I.O.N?

BK: ...

PBR: I'll take that as you can neither confirm nor deny those?

BK: I'm aware that there are rumours, but I'm not making any comment on those. The bottom line is, if Mark and I don't do anything else, we'll be doing Empire.

PBR: Fair enough. Is there anybody working in the industry that you haven't worked with that you'd like to?

BK: Oh yes, loads, the list could be almost endless. I'm wary to even begin listing people with fear of forgetting somebody!

PBR: I know that Geoff Johns is doing some great work at DC at the moment.

BK: He is, and I worked with Geoff on the Doctor Fate issue in JSA All-Stars. I think that was basically the reason I got offered the book I'm doing now. Geoff and I had wanted to work together for a long, long time and hopefully we will again in the not to distant future. We both enjoyed the experience J .... I think!

PBR: Okay, good. Moving on to comics generally, what's your opinion on the state of the industry at the moment? There seems to be a slight rut as far as getting new readers in goes.

BK: I don't know if that's actually the case; DC were telling me that their sales were up 13% last year, which is quite a healthy rise. A few people I know that own comic shops have been telling me that it's actually picking up again. There's now maybe half a dozen books selling over a hundred thousand, whereas a couple of years ago there was only one. I think it tends to go in almost seven year cycles; there are troughs and peaks. Sometimes the peaks get higher than others. We seem to be on an up-trend at the moment. I think things are a bit more together now; a couple of years ago things did look a bit dire but I think people have kind of rationalised now. To me it seems that more chances are being taken with stories and genres and that there's a fine depth of talent working in the field.

PBR: And the UK market?

BK: I'm ashamed to say that I'm not really up to date on the UK market at all. I used to get a few things when I was younger, like a magazine that reprinted Tales of Asgard, Jack Kirby stuff, but I'm a die-hard superhero fan through and through. Before 2000AD the British comics I bought were mostly titles like Fantastic and Terrific that reprinted Marvel comics. I did buy Look and Learn for Don Lawrence's Trigon Empire...though I'm sure my parents thought I was reading all the intellectual bits!

PBR: I see. So you're not tempted to work on anything a bit Vertigo-esque while you're at DC?

BK: I'd like to actually. Mike Carey and I have talked about maybe my doing something on Lucifer at some point if we get the chance, because he's somebody I'd like to work with; whether I'll ever get the chance to or not I don't know. I would like to do some other stuff, but I think it would always be like a holiday and I'd always come back to superheroes or sci-fi.

PBR: Sure. What advice can you offer to aspiring artists trying to break in?

BK: Basically, just keep working, keep drawing and try not to just copy from comics. There's nothing wrong with just doing that but if you don't draw from life as well, you kind of limit where you can go. You can become a perfect mimic of another comic artist but unless you draw from life as well, you can't take that style somewhere else. There are loads and loads of people who start by copying another artist but the ones who tend to make it move on from that and develop their own style, and the ones that do, do it by drawing from real life. The other thing is to actually listen to what people tell you when you show them submissions and things.

PBR: And actually take their criticism on board.

BK: Yes. You come across people, and you'll say 'Well you need to do this,' and they'll argue with you for giving them criticism - if you aren't prepared to hear some criticism of your work you really shouldn't be showing it to people! Criticism can only make you better, and help you analyse what you need to do to improve what you're doing. Another thing is, when you're starting out take anything; if you're offered work, don't ever think you're above it. It'll give you a chance to learn your trade. I do feel some sympathy for people who come into comics these days and get promoted straight away as the 'next big thing', maybe before they're ready for it. They often get dismissed before they get a chance to grow and really develop their style because they were forced into the limelight too soon, and that's a real shame. You're better just trying to keep improving all the time - there's nothing more disappointing than seeing that somebody's stopped trying and you can tell their heart isn't in it. Learn your trade. And most importantly, do it because you enjoy it.

PBR: Is that most important do you think?

BK: Probably. People sometimes start seeing it as a job and they lose sight of why they enjoy it, and maybe that's only natural, but when that does happen you just have to take a step back. It's not a job, it's a dream come true, at least for me.

PBR: And what's the working day like for you?

BK: I start work at maybe 7.30 or 8.00am and work through till about 8pm.

PBR: And that's five days a week?

BK: (Laughs) No, seven! Its not like I work solid, I'll take breaks, take the dog for a walk, that kind of thing.

PBR: Okay, some quick-fire questions for you; Jay, Barry or Wally?

BK: Hmmm...Barry.

PBR: Alan, Hal or Kyle?

BK: Hal.

PBR: I'm beginning to see a pattern here. Dick, Jason or Tim?

BK: Dick.

PBR: The ones you grew up with, right?

BK: Exactly.

PBR: Birthright or Man of Steel?

BK: Birthright.

PBR: Garfield or Snoopy?

BK: Snoopy.

PBR: Good answer. I think a lot of people say Garfield.

BK: Only the ones that are trying to be cool. Snoopy all the way.

PBR: What's the last film you saw?

BK: The League of Extraordinary Gentlemen on DVD last weekend.

PBR: Me too. It got a lot of bad reviews, but I kind of liked it. Not great, but it was a good fun film.

BK: Exactly. I think if you get a comic book movie and you go in and you're too precious and picky, then you'll be disappointed. If you go in with an open mind and don't expect a masterpiece, you'll be okay.

PBR: Okay, favourite film ever?

BK: I don't think that I really have a favourite film ever, it changes. I'm tempted to say the 'Thin Man' movies, but it changes from day to day. I'm really engrossed with 1940's movies for the JSA project at the moment - so almost any film noir title could have been named for this question! I don't really believe in 'all time favorites' in anything actually!

PBR: What comics are you reading at the moment?

BK: All of Alan Moore's ABC stuff, Birthright, Lucifer, Hellblazer, Fables, Planetary, Wanted, Arrowsmith, The Ultimates, 100 Bullets - I'd like to work with Brian at some point, particularly as we share a lot of the same taste in music. I tend to put stuff to one side and read it in batches; I just read the last JSA run the other day, including Black Reign, and that was good. If I don't like something, I'll just put it down. Aside from the stuff I get comp'd I also get Supreme Power, Fantastic Four, Ultimate FF, MK4 - although I haven't read that yet - and Hellboy, when it comes out.

PBR: Barry, this has been great!

BK: Thanks, I've enjoyed it.

This nifty little device will allow output of up to 24-bit/192kHz S/PDIF from a USB port. The hiFace looks a bit like an oversize USB flash drive with an RCA or BNC connector on the opposite end. Using a USB device allows one to employ a much smaller and easier to cool computer and I ended up with a "nettop" class of machine. This is much like the netbook laptops using an Intel Atom processor and a 2.5-inch hard drive. Passive heat sinks are enough to provide cooling without fans and the small hard drive is very quiet and inaudible from my listening position, avoiding the expense of a solid state drive. Unfortunately most of the USB devices, either DAC or S/PDIF output do not support the highest resolutions available and often use the PCM2702 from Texas Instruments, which is limited to 16-bit/48kHz. There are some very nice USB DACs available from Ayre Acoustics and Wavelength Audio to name a few but for the low budget audiophile like myself they are still a stretch of the wallet.

The M2Tech hiFace operates asynchronously with two high precision clocks covering the multiples of 44.1/88.2/176.4kHz and 48/96/192kHz. These clocks have a claimed precision of 2.5 ppm and very low phase noise. The use of a high performance transmitter allows the output to have extremely low jitter and M2Tech employs a pulse transformer to provide galvanic isolation from the computer. At this time M2Tech offers drivers for both the Macintosh and Windows operating systems. Linux support is forthcoming. Since my day job is working with Windows based machines I don't have any experience with the Macintosh version and look forward to giving it a go under Linux once the drivers are available.

The hiFace is primarily designed to use kernel streaming under Windows, regardless of version. This ensures low CPU utilization even at high bit depth and sampling rates and allows for a highly optimized driver. M2Tech supplies proprietary

Impeller Logs and Compasses

!±8± Impeller Logs and Compasses

Sailing and navigation...Measuring Direction and Distance

For Measuring distance at sea, the old type of log that gave us the knot as unit of speed has long since given way to more sophisticated mechanical and electronic devices.

Walker logs

One of the oldest is the Walker log. This uses a torpedo-shaped spinner a few inches long towed behind the boat on a length of braided line. As it moves through the water, spiral fins on the torpedo make it spin, twisting the line. The on-board end of the line is hooked on to the back of the log instrument, where it turns a shaft connected to a reduction gear box. This in turn moves the hands on a series of dials, rather like those of an old fashioned gas meter, to give Direct reading of the distance the spinner has moved through the water.

Advantages of the Walker log are its rugged simplicity and the ease with which weed or debris can be cleared from the pinner. Its disadvantages are that its display has to be mounted right at the back of the boat; that the log line (usually 30 or 60 feet in length) has to be streamed before the log can be used, and recovered before entering harbour; it tends to under-read at very low speeds; and at speeds over about ten knots the spinner is inclined to jump out of the water and skitter along the surface. There are definite techniques for streaming and recovering a mechanical trailing log, intended to reduce the risk of the line tangling. To stream the log, first attach the on-board end to the hook on the back of the display unit. Then, keeping the spinner in hand, feed out all the line to form a long U-shaped loop astern before dropping the spinner overboard, well off to one side of the loop. Some owners like to hold on to the line just astern of the display unit for a few seconds, just to absorb the snatch as the load comes on to the line.

When recovering the log, speed is essential, especially if the boat is moving fast. Unclip the inboard end from the hook on the back of the display, and drop it overboard, allowing it to trail out astern while you pull in the log line. Then holding the spinner, gather in the line, coiling it as you go. Trailing the line astern like this allows any kinks to unravel.

Electrical trailing logs

The electrical trailing log is superficially similar to a Walker log, inasmuch as it uses a spinner towed astern of the boat on a long line. In this case, however, the spinner is in two parts, and the 'log line' is an electrical cable. The front part of the spinner is attached to the cable and only the rear part is free to rotate. As it does so, an electronic sensor in the front part makes and breaks an electrical circuit, so the on-board display unit receives a short pulse of electricity each time the spinner rotates. These pulses are counted electronically and are presented as a digital display of speed and distance run.

The advantages and disadvantages of this type of log are much the same as for the mechanical Walker log except that it is dependent on electrical power from internal dry batteries, which in return allows the display unit to be mounted almost anywhere on board, and that because the line itself is not twisting, it is rather easier to stream and recover.

Hull-mounted impeller logs

On cruising boats, hull-mounted logs are by far the most popular type, though in principle they are much the same as the electrical trailing log: a rotating impeller sends a stream of electrical impulses to a display unit mounted in the cockpit or near the chart table.

The impeller - which can be either a miniature version of the trailing log's spinner, or a paddle wheel an inch or so in diameter - is mounted in a fitting called a transducer, which either protrudes through the bottom of the boat or hangs down below the transom.

The disadvantages of this system are that an impeller so close to the hull can be affected by the water flow around the hull itself, and that it is difficult and potentially dangerous to withdraw the transducer to clear weed or debris from it at sea. The reason in-hull logs are so popular is primarily the convenience of not having to stream and recover 30 feet or more of log line at the beginning and end of each passage.

Other logs

At the top of the scale of price and sophistication are several alternative methods of measuring speed through the water:

Electromagnetic logs are based on the same principle as generators and electric motors: that electricity is created if you move a magnetic field past an electrical conductor. In this case the conductor is sea water and the magnetic field is created by the transducer. As the transducer moves through the water a small electric current is set up, measured by sensors on the transducer.

Sonic logs use accurate measurements of the speed of sound between two transducers mounted one ahead of the other. Each transducer emits a continuous stream of clicks, inaudible to the human ear, while listening for clicks transmitted from the other. When the boat is moving, the movement of the water past the hull slows down the clicks travelling forward whilst speeding up those travelling aft. The instrument accurately measures the time taken for each click to make the trip, compares them, converts the results into a display of speed through the water, and from this calculates the distance run.

Another type of sonic log uses sophisticated echo sounder technology to measure the rate at which plankton and debris are moving past its transducer.

The big advantages of all three types are that they are much less susceptible to fouling than ordinary in-hull logs and that they can go on working at very high speeds or in rough sea conditions, when turbulence or air bubbles make impeller logs unreliable.

Calibrating logs

No log can be relied upon to be 100 per cent accurate. This is particularly true of hull mounted logs because - quite apart from any inherent inaccuracies in the instrument itself - the gradual build-up of fouling as the season progresses means that the boat is dragging an ever-thickening layer of water along with it, so the water flow past the impeller will be slower than the boat speed through the water. Conversely, around some parts of the hull, such as alongside a sailing boat's keel or near the propellers of a motor boat, the water flow may actually be accelerated, making the log over-read.

Errors can always be allowed for if you know about them, and most electronic logs have a calibration facility that allows them to be adjusted to take account of these variations. Finding, and if necessary, correcting, log error is known as calibration. In principle it involves measuring the time taken to cover a known distance, using this to calculate true speed, and comparing this with the speed indicated by the log. Any accurately-known distance can be used, though the best are undoubtedly the measured distances' set up specially for the purpose. They consist of two (or sometimes three) pairs of transit posts, marking the start and finish of a precisely-measured distance, and shown on the appropriate chart. The course to steer to cover the Measured distance is also shown.

Settle the boat on course and at a steady speed before crossing the first transit line; note the time at which you cross the start ine and hold that course and speed without making any allowance for wind or tide until you cross the finish line, and note the time taken. Note the actual log reading at intervals of, say, 15 seconds so that you can work out the average log speed for the whole run.

As perfectly still water is rare, it is important to repeat the process in the opposite direction. Having found the speed over the ground in both directions, the speed through the water can be calculated by taking the average, by adding the two speeds together and dividing by two.

A more accurate result can be obtained by making four or six runs, but this can be a very
time-consuming process, especially as log errors are not necessarily the same at all speeds, so the calibration runs need to be carried out at a range of different speeds, and repeated as a double check after the log has been adjusted.

A common mistake is to work out the average time taken and divide the distance by this. The result invariably understates the boat's speed, because it must have been travelling in the 'slow' direction longer than in the 'fast' direction.

Some large scale charts (harbour plans) have a clearly marked scale of distance - rather like the one you might find on a road atlas - usually printed somewhere near the bottom edge. But this is not always the case, and on the smaller scale charts used for coastal and offshore navigation it would be impractical to provide such a scale because the scale of the chart varies slightly from top to bottom. One sea mile, however, is by definition one minute of latitude, so the latitude scales on each side of the chart constitute a scale of distance.

The slight difference between a sea mile and an international nautical mile is so small that for normal navigation it can be ignored: what is important, on small scale charts, is the distortion caused by the Mercator projection, which means that distance has to be measured at the latitude at which it is to be used. The longitude scale on the top and bottom edges of the chart is useless as a scale of distance.

It is relatively rare to find ourselves faced with the job of measuring distance in an exactly north-south line, so we need some means of transferring the distance between any two points on the chart to the latitude scale. Dividers are the tool for the job. For classroom navigation the kind of dividers used in technical drawing are perfectly adequate, and their sharp needle points give a reassuring sense of precision, but for practical navigation, traditional bow dividers have the big advantage that they can be opened and closed with one hand, by squeezing the bow to open them, and squeezing the legs to close them.

Sometimes it is necessary to draw arcs of measured radius on the chart, for which it is useful to have a drawing compass. Again, the type intended for technical drawing can be used so long as it is big enough, but it is generally better to use the larger and less sophisticated versions intended for marine navigation.

Compasses and Measuring direction at sea

Direction at sea is measured using a compass - essentially an instrument which points north, and goes on pointing north regardless of the movement of the boat around it. In practice most yachts carry at least two compasses. One, steering compasses are relatively large, fixed to the boat, and used to measure heading. The other is usually smaller, portable and is used to measure the direction of distant objects, so it is called a hand bearing compass. Sometimes one compass can do both jobs: on many ships and a few large yachts an attachment called a pelorus allows the steering compass to be used for taking bearings, while on very small craft, a hand bearing compass clipped into a bracket can serve as a steering compass.

There are many ways of making an instrument that will stay pointing in one Direction, including gyroscopes, and what are called 'ring laser gyros', but although these have their advantages, they are much too sophisticated, and therefore expensive, to be of practical interest for yachts. The Overwhelming majority of yacht compasses Depend on magnetism, and in that respect can be seen as direct developments from instruments that were probably in use several thousand years ago. Compasses make use of the fact that the earth has a magnetic field, which is very much as though a huge bar magnet were embedded in its core and aligned with its North-South axis.

Any magnet that is free to swing tends to line itself up with the earth's magnetic field. This effect is particularly obvious in the small, flat compasses used for orienteering and rambling on land, in which a single straight needle-like magnet gives a direct Indication of north. In marine compasses, several such magnets, or a single magnet in the shape of a ring, are mounted underneath a circular 'card', with a scale of degrees or compass points marked on it. The whole thing is suspended in a bowl filled with a mixture of water and alcohol, which slows Down the movement of the card, to reduce the swinging that would otherwise be caused by the pitching and rolling of the boat.

Compasses intended for fast motor boats are much more heavily damped than those intended for sailing craft; the rapid slamming of a planing boat can be enough to make the card of a sailboat compass rotate continuously.

Steering compasses

On a steering compass the fore-and-aft line of the boat is marked by a line or pointer on the compass bowl, called the lubber line, against which the boat's current heading can be read from the card, so it is obviously important for the compass to be installed so that the lubber line is accurately aligned with, or parallel to, the centre line of the boat. Many compasses have supplementary lubber lines offset by 45° and 90° on each side, intended mainly for use in situations such as tiller-steered boats where the helmsman is likely to be looking at the compass from one side or the other.

Of course, there are variations intended to suit particular applications. On many small and medium sized sailing yachts, where cockpit space is at a premium, the compass is set into the aft bulkhead of the superstructure, so that the rear edge of the card is visible, rather than its upper surface. A compass intended for this type of mounting has an aft lubber line and a scale of degrees marked on the down-turned rim of the card. An even more extreme variation is occasionally found in compasses intended for steel craft, whose structure effectively masks the compass from the earth's magnetic field. This problem can be reduced by mounting the compass as high above the hull as possible, so compasses have been produced that can be mounted on the wheelhouse roof, with mirrors or prisms arranged so that the helmsman effectively looks upwards at the bottom of the compass card.

Grid compasses

Grid compasses, intended primarily for aircraft navigation, enjoyed a surge of popularity after the Second World War, when many boats were fitted out from Army surplus stores! The claim that they were easier to steer by maintained their popularity for at least 20 years and several marinized versions were produced. A grid compass has a card with a particularly prominent north set in a flat-topped bowl. On top of the bowl is a transparent cover, marked with a grid of parallel lines and with a scale of degrees es around its edge. The required course is set by rotating the cover, and the helmsman then steers so as to keep the --. mark on the card lined up with the grid.

Hand bearing compasses

A hand bearing compass is basically a small, portable version of a steering compass, fitted with some form of sighting arrangement that allows it to be accurately lined up on a distant object. They can be subdivided into two groups: those intended to be used at arm's length, which are usually fitted with a handle; and those intended to be held close to the eye, which are usually supplied with a neck strap. Which kind is best is very much a matter of personal preference, but anyone who uses spectacles or a hearing aid is well advised to go for an arm's-length compass because even small pieces of ferrous metal such as the hinges of spectacles can cause compass errors if they are only inches away.

Sighting arrangements vary. The classic Sestrel Radiant, for instance, has a prism mounted above the bowl, with a V-shaped notch on top. When the compass is held up at arm's length and eye level the lubber line and compass card can be seen in the prism. To take a bearing of a distant object, you line up the 'target' with the notch, rotate the compass until the lubber line appears in the prism immediately below the target, and then read off the bearing. Another common arrangement has two sights on top of the bowl, like the fore sight and back sight of a gun, and an edge-reading compass card. Close-to-the-eye compasses do not have such obvious sighting arrangements: instead they have a small prism mounted on top, whose optics are arranged in such a way that when you look at a landmark across the top of the compass, its bearing appears in the prism immediately below.

Fluxgate compasses

A new type of compass is rapidly gaining in popularity. Unlike a conventional 'swinging card' compass, a fluxgate compass has no moving parts, but instead uses electronics to detect the earth's magnetic field and present that information on some kind of display. A fluxgate depends on the phenomenon of electromagnetic induction - as used in transformers and the ignition coil of a petrol engine. If you pass an electric current through a coil of wire wound around a suitable metal core, the core becomes a magnet. Which end is the north pole, and which the south, depends on the direction of the current flow in the wire, so if you apply an alternating current to the wire, the north and south poles of the core change places each time the current reverses. If you have a second coil of wire wound around this whole assembly the constantly-reversing magnetic field induces an electric current in the secondary winding.

In a fluxgate there are two cores side by side, with their primary windings receiving alternating current from the same source, but wound in opposite directions. This means that in a magnetically 'clean' environment (with no external magnetic influences) the induced magnetism in the two cores would be equal and opposite, so they would cancel each other out and produce no current at all in the secondary winding that surrounds both of them. The presence of an external magnetic field upsets the balance, causing a short surge of electricity in the secondary winding each time the primary current reverses. This effect is most pronounced if the two cores are parallel to the external magnetic field. In a practical fluxgate compass, several fluxgates are arranged in a circle. By comparing the voltages induced in the various secondary windings it is possible to deduce where north is relative to the ring of flux-gates.

At present, the most common use of this technology is to provide heading information for other electronic equipment such as autopilots or radars, but it can also be used to provide a steering display for the helmsman or as the heart of an electronic hand bearing compass. Apart from the ease with which fluxgate compasses can be connected to other navigational electronics, their big advantages are that they can be fitted with an automatic correction facility, and that because the sensor and display are usually separate from each other, the sensor can be mounted anywhere on board and well away from distorting magnetic Influences. Fluxgate hand bearing compasses also have the facility to 'store' headings, to save the navigator having to memorize them.

Their main disadvantage is that very large errors can occur if the fluxgate ring is not kept perfectly horizontal. There are electronic solutions to this problem, but the fact remains that the compass without moving parts actually requires more sophisticated gimbal arrangements than its swinging card counterparts.
