    DC-DC PSU

    Sweet! You could just keep hooking up multiple DC-DC power supplies to each other until you have enough electricity to power the world! All from a single ATX power supply! ;) You are correct, it is not possible to create energy from thin air. You can create energy from thick air...

    analog circuit trouble shooting

    How are you testing the diodes? Are you measuring them while they are in circuit? If so, this can provide erratic readings. Also, check for solder bridges. It sounds like you may have connected a couple traces by accident. It's also possible you overheated an IC with your iron...

    Fitting a square peg in a round hole: small DC motors

    1.) You can use the epoxy method that was already explained, or use a set screw. Most of the time I see set screws used. 2.) Custom mount. Each motor is different. sometimes they have tabs, bumps, notches, etc. to fit a bracket into. Some even have threaded holes on the business end so...

    Controlling Cold Cathodes w/ Fanbus

    I've hooked up a cold cathode to 5v by accident, and it worked. It was dim, but it didn't sound like it was going to explode or anything. Your milage my vary.

    A question about swapping wire colors and wire crimping

    You don't need to pay $50 for crimpers, although you certainly can if you want nice ratcheting ones. Regular molex crimpers should set you back around $15 - $30 and you'll be able to do all types of pins with them. http://www.action-electronics.com/molex.htm#Tool I personally own these...

    Yet another reason why <75Hz Refresh sucks

    I'm glad somebody mentioned this. The problem people have is with OLD fluorescent lighting using magnetic ballasts. Modern fluorescent lighting (whether it be compact fluorescent or T8) use electronic ballasts that drive the lamps in the KHz range... meaning, they don't flicker at all I wish...

    Faraday Cage

    Is that a Beta Brite display? if so, do you know of some sort of interface program for WinXP that will work with it? I've got a Beta Brite laying around, and using the remote is a huge pain in the ass.

    Looking for Lightest, Most Batt Life Laptop...Money = Whatever Amount

    I'll vote for either the IBM X series or T series. I have a T42 and I love it.

    IBM T43 details break cover

    Like the other guy said, get a T42! I got a 2378-FVU and I couldn't be happier. I paid like $1900, but you can get them cheaper now. Just upgrade it to 512+ MB of ram, and you are set.

    Is a dual-cpu board fast for single applications?

    That's a very good question. I only remember seeing it on Windows 95, and possibly 98. I didn't have 98 for very long, because I switched to NT4 - and I don't remember seeing it on NT4 at all. I could be mistaken though.

    Is a dual-cpu board fast for single applications?

    I've seen it before. The last time i noticed it was with a 2X CD-ROM drive and Windows 95. It was a very short dim pulse, but it did exist. It probably happened around 1 time per second. It can make your IDE activity light blink too...

    $75 computer build

    How about this mobo: http://www.newegg.com/app/ViewProductDesc.asp?description=13-185-010&depa=1 Plus this CPU: http://www.newegg.com/app/ViewProductDesc.asp?description=19-104-159&depa=1 You wouldnt really have any more money for RAM though.

    Only certain video cards are supported under Maya's hardware rendering mode. You don't need to use hardware rendering mode though. It's a relatively new thing. You can always render in software, just like everyone used to...

    Which Notebook would you choose?

    Between those two, I would pick the Fujitsu. I personally own (and am typing this message on) an IBM T42, and I love it. I would vote for the X40 if you can handle a slightly bigger laptop. Thinkpads are the best laptops money can buy, and I love the Trackpoint!

    Danger in building a headphone amp?

    You would have much difficulty killing yourself with a CMOY amp, unless you tried swallowing the assembled unit.

    Why are the heatsinks and fans on the bottom?

    Honestly, i've called them cards since the ISA days. The terms have always been interchangeable, with "card" being more of a slang term. "adapter" is the more technical term. Modern day video cards are still called adapters. Take a look at your Windows device manager, and your video card...

    need help identifying thing

    Well if you don't want to send it in for repair, you could try calling up their service department and running your problem by a few of the guys there. Chances are, they've heard of this problem before and they know how to fix it. They'll know more than we do, anyway.

    What makes you so sure that the problem is with that board? Have you swapped it with a known good one?

    need help identifying thing

    Hmm, i'm not to sure. I don't have a whole lot of experience with projectors other than replacing lamps and filters. Try taking the lamp out completely, then putting it back in and making sure its secure. And just because its only got 40 hours on the clock, doesnt mean its good... a nasty...

    need help identifying thing

    No, it's not leaking anything. The goop is there intentionally, so the pot doesn't move around by itself.

    need help identifying thing

    Those pictures are terrible and useless. Sorry. But from your description, it sounds like a potentiometer. A potentiometer is a variable resistor of sorts, and manufacturers frequently lock them down to the proper setting by using hot glue or a special paste, to keep them from moving. This...

    I hate Laptops

    Test the diode. Cut one leg so you can take it out of circuit, then apply the diode test function of a multimeter. You should get a small voltage drop one way, and infinite resistance the opposite way.

    For those of you looking for a sub $100, yet capable multimeter

    No, i'm not selling anything. I was at work today, and we recieved our latest catalog from Jensen/Contact East and I noticed that they had some new Jensen brand multimeters. I was immediatly drawn to this one: http://www.jensentools.com/product/group.asp?parent_id=420876 I haven't seen...

    why are the nForce drivers so big?

    I don't have an nForce3 but if I had to guess, I would say it's because of the onboard firewall.

    Broke out Quake I last night.

    This brings back so many memories. I remember downloading the original Quake demo over my 14.4 modem the day the demo was released. It was split up into something like 8 parts so it would fit on floppies. You could also download one GIANT (10mb or so) zip, but I couldn't because my modem...
