It's like I'm a kid in a candy store when I'm in there.
Anyway, I bought (just to play around with):
1) One thing labeled "transducer" which I thought was a little loudspeaker but turns out it transduces the other way - must be a microphone.
2) Three light-emitting diodes.
3) One little DC motor
4) One buzzer (I hooked that up to make a little code key system to practice my morse.code).
5) 100 feet of run-of-the-mill high-AWG # wire.
6) One toggle switch
7) One momentary normally closed pushbutton switch.
And that's it. Any of you guys ever go buy stuff like that just to play with?

I used to toy with electronics and robotics when I was younger but it gets to be an expensive hobby after awhile.
I'd knock on wood, but my desk is particle board.

I know exactly how you feel. I used to, and still do, make little electronics projects
My most memorable project is a "dark activated switch"

I have quite much salvaged parts from broken things I've disassembled.
I almost never use the things, but that's beside the point, and why
throw away something that's working?

I have a monitor casing (Yup, you read right, the shell of a monitor) filled with electronics stuff, engines, wires, switches, diods, you name it.
There's even a few circuit boards in there, 5-6 computer mouses (or is it mice?
) some small penumatic thingys, (cables, pump, storage tank (a small one, like about two fists in size) and those things that shoot out if you pump air into them, or retract if you suck it out.. dunno what they're called though... silly) pretty fun stuff you can build using that... my current project is some sor of robotic arm, or something. Best thing you can do when power goes out (provided you have batteries)

It seems you guys are a bit more advanced when it comes to projects than me.
I installed a homemade doorbell buzzer into my room, activated by the toggle switch.
Next time I go to the electronics store, I'm going to stock up on some more effective, "smart" stuff like transistors. Maybe I'll pick up some thicker wire (I used the 100 feet all up for a shortwave radio antenna) and solenoid coils. And more switches.

I read this in a slashdot comment,
(from memory)
It basically a small little device that is hooked to a 555 timer and a batery. it uses one of those cell thingy (forget the name) so that every 5 minutes that the light is detected as off it beeps. When you turn the light on the look for it it doesn't beep. Hide it in your friends dorm =P

I will byte and nibble you bit by bit until nothing remains but crumbs.

Probably a photoelectric cell.
The 555 is a good general purpose timer circuit but the 7555 is better, even if it does have a slightly higher drain.

Instead of that photoelectric cell you mention, couldn't a photosensitive diode be used? I'm just thinking of cheapness.
