Does anyone here know what is the smallest cable-ready television
available?  I want it for its tuner and audio/video inputs/outputs, not

I was think of buying on just for the battery pack. Its less than the cost of

What is the suggested reference book for electronics? I'm an electronics
student and I would like to get something really extensive to use as a
reference, for all that has with electronics to do - for example
components (for example capacitors, flip-flops, OP's, everything) and

I know there are many packages that design PCBoards and have all the bells

I was thinking about the classic voltage doubler using caps today, and
this got me thinking about the basics of capacitor charge/discharge
math, and eventually I thought up a simple design but wasn't quite sure
what the effects would be:

Do capacitors collect energy and store it until an external event
causes them to discharge.  Or are their capacitors that will collect
energy and store it until the capacitor hits some peak level and
discharge on it's own.

Hi,  This must be a common question, but I can't find anything relating to
it in back postings on my machine. What's the effect of parallelling two

Can you actually break something by doing it with ordinary ...

My wife turned up an automobile cigarette holder adapter made by XG this

Anyone got any good tips for doing a good quality double sided board?
My current thinking is to drill two large holes in the board
