I received this curious object from my science teacher today because he is cleaning his room. He does not know what it is, all that he knows is that it is related to Lego Mindstorms(I am assuming very old Lego Mindstorms the floppy disk he gave me that comes with it is dated 1988) and a mac 2.0. There is a power source, a ribbon cable, old lego cable, and what appears to be the remains of a button attached to it. It also came with a floppy disk i don't know if the labels mean anything so i am including it. right underneath the switch there is a label that says TSI interface on/off. the floppy disk says " "Feelies" sensor interface for the apple p.o. box 5362 bla bla bla bla more stuff about the address then front: 2e version back: 2+ version". there is also what i think is a brand on the box that i think says "T.51n" but i'm not sure. if anyone knows what this is and what it does please do tell. thanks, Harry

I have recently acquired a Sony Mavica MVC-FD95, and i noticed a little port or something on the lower right-hand corner, and it was intriguing to me, because it might be a media drive; a Godsend seeing as this camera only takes 3 1/2" floppies, as far as I know. If you know what is please post. :)

I got this of of a portable heater with a fan and it had labels for fan speed. it has four settings when you turn it. When i try to use on a motor to control the speed it just works as a switch. Do i need a motor with 3 wires if so how do i wire it up? Is it something different.

I recently got this "motor" in a box full of old telephone supplies. It didnt come with any instructions or anything on how to use it, which some of the stuff had. It looks like a giant motor. Any ideas? It says Teletype Corp on it, but I couldnt find any details on it anywhere on the internet.

I came across about 100 of these, I am not sure if they are photodiodes or LEDs would like to use them for something! Have tried them at alot of different voltages, they all have a resistor inline with them which makes me think they are LEDs not sure on operating voltage. they also have a glass lens. markings - mexico 1150

I found this in a box of misc. wires yesterday at a thrift store looks like a toy for a computer game maybe. It has a speaker up top and an adjustable microphone at the bottom. I know that speaker and microphone are self explanatory, but I was curious to know what exactly it may have been used with. It has a place in the middle to put in three AA batteries and it has a removable clip to attach it to something. When I put in the batteries it appeared to work or the little red light indicator came on and the speaker was on with a real low fuzz sound. I have not plugged it into anything yet , I wanted some input first.Thank you in advance to anyone with help.

Hey guys, I am having problems understanding what is a transistor. When I do a search it shows me that its made of semi-conductor material and stuff, I don't want to know that. I want to know what is does as in a battery supplies power, resistor limits current etc. I would really like it if someone could give me a basic explanation of what is a transistor. Thanks in advance :). -Prickly Potato

Christmas is coming up, yay!!! On the 6th I ordered some shutter shades from www.shuttershadesonline.com My brother is a Kanye West fan. It has been over 2 weeks (almost 3 weeks on christmas) and they still havn't shown up. If they don't come, what do I tell my brother? I'm not too worried, because the thought was there, ordering something 3 weeks before christmas is good i think.

I have puled two components out of an old radio/amp/ cd player etc. and i want to know what they are and if i can use them to make an audio amplifier. one says BC Power Module SVI 3101 D on the front and 424 1w2 on the back and has 14 legs (it can be seen here, this is actually the exact one i have from the same appliance : http://farm2.static.flickr.com/1042/4733036801_a2d72f1df9.jpg ) . The other looks kind of like an op amp, it has 12 pins and the part no 5a3920, and below that 218 130a (as you can tell i am not a good at desoldering and not having a solder suck doesn't help).
