Okay. I'll start out by saying that this is *not* a homework problem.
I'm trying to recreate some work I did many years ago which I
subsequently lost the notes and spreadsheet for.
My ultimate pr...
I want to make a load center to test power supplies and batteries. I
was thinking of using 50 Watt 4 ohm resistors for 12V loads but I will
need 15 of them to get the current drain I want. I wou...

Hi
I've just moved house and want to get my TV video NTL box DVD connected.
I had this set up in my old house but now it's turned into a nightmare.
I want to be able to tape on my ntl box and DVD...

Looks like this news group has gone the way of some others.
It's inundated with advertising; for Gucci and Rolex cheap copies,
imitation or over-stock Nike shoes etc. doubtful services or site

I haven't heard much about television detector vans lately but we used
to be told that they could detect a television even if it was switched
off and they could even tell which room it was in.

I was taking apart a broken rechargeable razor, and found a 0.15 uF,
250V capacitor in series with the primary of the (tiny) transformer.
The tiny ...

Does anyone know if one can test a varactor to see what capacitance it is
exhibiting while it is being used to tune a circuit? I would think that
hooking the meter across the varactor while it is...

Hi,
I just built Velleman 8061 and got it eventually working - I think?
But I have a question.
Shouldn't I be able to see whether line is active by resistance meter
over the transistor?
I...

Hi,
I am testing several things and now I would need a
very exact current and voltage source.
It would be nice if it were correct to 0.001mV/mA.
Even more is better but I think that pushing a li...

I need some project boxes and was hoping to get advice on how to make
them.
I ruled out metal because small PCBs will be the contents of the boxes
and for obvious reasons this will not work.
