G'Day all.
Many years (at least 15-20) ago my dad made a 240V touch light dimmer from a
kit. Quick touch on-off.  Fingers on dim-up/dim-down.  The finished product
consisted of a brushed aluminium plate in a blank HPM mount.  They have

These are brand new in the tubes, they are NOT pulls from game carts, etc.

Probably hundreds out there, but I wondered if anyone knew of a model
that is reasonably weatherproof.
Are any of the transformers for garden lighting weatherproof?
Need about 1.5 amps at 12v DC.

We've got a problem with the front passenger electric window on our AU
Falcon - basically no go on this door. Before I spend half a day buggering
around has anyone had this occur / is it a known issue with a known fix?

I'm leaving on vacation tommorow and I want to take my graphics card
with me. I don't have any of those anti-static bags, so what would be
a good way to transport it?

I have some transistors (i think) that I cannot identify.
They are labelled FFT0601 in a TO-72 metal can, 4 lead
The 1st F is bold and larger than the rest of the part number and I thought
that would indicate Fairchild.

I am doing a project for someone that involves using the A/D converter
on a PIC18F1320 microcontroller. I believe I have it all licked, apart
from I just cannot figure out how to use the A/D converter properly.
This is my first experience with microcontrollers, so please forgive ...

   I'm the first to admit I don't know anything about LCD projection
TVs. A friend of mine's SP56L5HX developed a yellowish hue in the
picture which is shifting towards green.
  I've done some Google searching to find the likely cause, but

Anyone using these in projects ?
I fired mine up and came to the conclusion that it was picking up garage
door openers and my weather station as well.
Seems it might be better to run it rf on is equal to a space and no rf is a

I was cooking mongolian lamb in my electric wok tonight when I decided
I should put away the multimeter sitting on the bench nearby so I
picked it up. Unbeknownst to me, the leads were sitting under the base
of the wok, and when they drew taut, the meter flew from my hand and

We''ve got a baby swing that eats four D batteries faster than my son
can empty a 1/2 full bottle of breast milk. I'd like to get an AC
adapter and wire it up to do the job. I've got my soldering merit badge
but this would be new territory for me. Here's my plan so far:

These typical UPS systems from APC, et al. obviously can run a computer
because they become an inverter when the AC input drops out.  I don't
believe that the output then is a pure sine wave.  Perhaps it is a square
wave or modified sine wave?  In any case, what types of equipment ...

I have 8 tubes of CP25WB 3M Firestop. Make me an offer. Thanks...

On many computer circuit boards, mainly motherboards, traces will fill areas
with "S"-shaped and wavy lines that seem to meander around themselves,
rather than go in a straight path to the destination.  In fact, certain (but
not all) tracings will often zig-zag (with smooth corners) ...
