Re: LCD monitor power supply
Replacing components on multi-layer motherboards can be daunting, and the chances of success are not very high IMHO. I would not advise the average "Electronics 101" participant to attempt it. Roland

Re: LCD monitor power supply
Peter Morris: I agree with most of what you claim. But why try to repair something that can be replaced (exactly) for a few bucks? I don't how various people value their time, but breaking open a

Re: Offset standard .1 header Eagle PCB article with component library
Yes, it was definitely on the Sparkfun site - although I didn't try to look for it again. I use FreePCB, always design my own footprints, and ever since I read it I have always offset one of the holes

Re: LCD monitor power supply
The reason that you can often get away with using the wrong "brick" is because most of the monitor's internal circuitry requires voltages other that 12 (usually 5 and 3.3 among others). The monitor

Inspiration for the 555 timer design contest
A couple of articles from EDN magazine about the 555 timer, including news of a new version from Advanced Linear Devices, the ALD7555 and ALD7556. Sounds like the CMOS version on steroids.

Re: Source for 5KV ac supply?
Scrounge up an old-school neon sign transformer (i.e., "iron" as opposed to a modern switching-type NST) and feed it with a variac. Or possibly a microwave oven transformer feeding a simple voltage

Re: Plugging holes in bakelite.
Actually, you make a good point. If the holes a little then any hard curing epoxy should work fine. Bando isn't so bad it you trim it down with a knife or chisel before it gets rock hard. James "Jim"
