Hi,Quote from: SmAsH on April 17, 2009, 04:39:41 PM[...] i dont think you will find photocells anywhere but its possible, [...]Just get one of the large office photo copiers (those the size of a small fridge), they are full of goodies.In a single machine, I have found around 20..30 IR photo "forks" and a handfull of SHARP PSDs, about 60..80 microswitches, some of them optical and tonnes of mechanical parts, motors, springs, axles and what not.Getting two of the same model should be possible if you really sweet talk your local photo copier service central technician.
*SIZZLE" *POP* *BANG*And you see the micro controller slowly sink into the board and black ooze fills all the little holes in your board, it melts the wires and engulfs the LED then spills into the battery pack, ruining your $20 EACH rechargeable AA batteries !
Dont forget that your talking to somebody that is 12 years old. Where would he/she come by an old photocopier... and how are they gonna use the parts that arent like for like replacements of the $50 robot
