OMG copiers are great for components. Especially the bigger ones that have a lot of paper handling i.e. many paper feed trays, document feeder, finisher (stapler). Find a nice big one and you'll find all kinds of motors (steppers, servos, 3-phase DC), solenoids, sensors, clutches, and of course the appropriate components to control them (IC's). Some of the motors are fairly hefty. The components are 24v but naturally there'll be a beefy power supply in the copier to put out all the necessary voltages 24v, 5v, and sometimes others. Lots of wires, connectors, microswitches too.Depending on the machine there'll also be pulleys, belts, gears, bearings, bushings, rollers, shafts, etc.If you go to your local copier dealer I'm willing to bet that at any time they're going to have one or more that they're ready to just throw in the dumpster that they'd be more than happy to give you. I know all this because I have a copier dealership and I've always found it a great shame seeing all that stuff go to waste. Lately I've been trying to harvest as much as I can from them before the scrap guy picks them up, but I have a hard time keeping up.
im harvesting parts from everything old laptop to printers shit like that but for the laptop i was wondering if anyone knows how to make a ethen et hook up for the arduino without buying a ethenet shield so practicly wanting to build my own, or how about the wifi card in a laptop can it hook up with some tweeks?
In one of the printer that I find in the garbage and took appart... I find a very interesting 40 pins IC, non SMT, I read the number of that part....---> 8255 <--- I say : NO WAY !!!! an old Intel PIA chip and maybe functional. A PIA is an I/O chip that a early CPU like 8085, 8080 or 8086 can "communicated" with the outside world... Just like an ATMega328 - Ardiuno, except the Arduino have all in one chip ( CPU, Memory, PIA, UART )
@cr0shThe printer in question is : Cannon K10149 Centronic / Parallel Interface Here the inscription of the "8255"QH7-8787-03V1.04M5388002E-F18255B01I may jump to conclusion to early...
