Found in the Electronics Waste Bin at work. Being cheap, I thought I'd give it a go to see whether it stores anything useful. Tools needed: Phillips, Pozidrive and Flat screwdrivers, Two idle hands and a Free-wheeling Brain. Work it like you'd uncover an onion - loosen all visible screws in the outer layer: bend/ twist/ tear the outer plastics shells. unplug all cables at the boards and keep as much cable as possible to each liberated part, Side cutters aren't really necessary. Take your time to figure out how it's been assembled - then do that backwards. Careful, as not to break any delicate parts. One piece at a time, keep it as complete as possible (you can always dismantle later - but try to reassemble a working gearbox from a pile of plastics...)! The things I find useful are fairly rugged: Stepper motor plate w its entire gearbox, Axles, rollers etc can be fiddly to get out, tape their respective end gears and parts to them. IR photo gates, solenoids, micro switches, springs, all POM-marked plastics (as it's the best bearing plastics of all!) Polycarbonate/ Lexan is rugged and translucent so it sticks too. I discard most other plastics, marked PA, PS, PET, ABS, etc, most structural steel plate, almost all computer/ display boards, PSU boards might be useful, as well as a keypad. My maxim is: Keep electromechanical stuff: motors, solenoids, relays and the like, and ditch anything with ICs on - but some electronics peripherals may be handy depending on your prefs, skills and needs.
