One week after I came up with the idea, the thing stands at 19 pages. That's not too shabby.

I just discovered something interesting.
At work a couple of weeks ago I found a gift card in Receiving. It was one of the ones we have that light up. In a fit of curiosity I busted it open and took out the circuit board, which I still have; it's sitting on the desk. It's got three button cells, three white LEDs, and a simple timer circuit IC (potted in black epoxy) which keeps the lights on for about 8-10 seconds.
I reached over to press the button, and the LEDs went on as soon as I touched the button, without me even pressing it. I waited until they shut off, and did it again; then it stopped.
Thinking it was static electricity, I rubbed my feet on the carpet and tried again. No dice. Rubbed more, bingo.
Tried doing that again, no dice again. WTF?
Then I discovered that I was getting my static charge from the desk lamp.
The desk lamp is a typical cheap architect's lamp with a CF bulb in it. I held my hand under the bulb, maybe 2 inches away; then I was able to switch on the LEDs just by touching the button.
...actually it's because the CF bulb emits an EM field. It's not a very strong one. If I don't hold my arms away from my body the charge dissipates. I can't touch anything other than the button; otherwise it doesn't work. That's one sensitive circuit.
This reminds me of when I had my plasma globe and touch lamp Earth globe plugged into the same outlet. I could light up the touch lamp by touching the plasma globe, the same as if I'd touched the lamp itself. That was pretty cool. I even understood why it worked: the plasma globe provided an electrical link to the touch lamp; if you touched the plasma globe, you completed basically the same circuit as if you'd touched the lamp. It's like hooking a plant to a touch lamp and touching the plant.

Projected high for today: 5°F. I'm getting sick of the temperature roller coaster. (Literally. Though my cold is better than it was.)
When I lived in Cedar Rapids, at the end of every week the Sunday night weather forecast would include the "weather coaster". It featured a graph of the temperatures over the week, and a little graphic of the weatherman in a roller coaster car would follow the graph. I'm betting the "weather coaster" is a pretty interesting ride this winter.

Seagate got my broken 500 GB drive Friday. Hopefully I'll get my replacement soon.

Sitting on my shelf is a 1979 series Matchbox Rolls Royce Silver Shadow II, which I--for reasons lost to the mists of time--painted day-glow orange. I think I was going to paint it to look like the General Lee. Dukes of Hazzard was on then and I watched it, being about the age of that show's target audience. (12.) And the R-R was the closest thing I had to a 1970 Dodge Challenger.
Well, in 1979, the 1970 Challenger was just some old car; thanks to price controls gas was expensive and in limited supply (this was during the "energy crisis" and "economic malaise") so it was a gas guzzler and the mystique surrounding muscle cars had evaporated before the fall of Saigon. (In 1975, "for those of you in Rio Linda.")
There was no way Matchbox was going to bother with rustbucket used cars.
So one of my two R-Rs--the one that was scratched and gouged anyway--got painted orange; but I never got around to adding any other details. I didn't do any paint prep before painting it; the scratches and gouges show right through the orange.
I had managed to disassemble it before painting it, too. So when I was trying to find all my old model railroad stuff, I found this in a box with some of the old track, in pieces. I put it back together, and now it sits on my bookshelf.
But the intervening time has not been kind to its running gear. The wheels don't turn very well; so really it's more of a "Slides Royce" than a "Rolls Royce".

That was a long way to go for that joke. I shouldn't have bothered.
