Thanks everybody for the explanations! Everything start to make sense now. I understand that a resitor will limit only voltage across the circuit, but not current, this is very clear also. So, i will look for a small electromagnet, (9 volts) because (...) (18 years ago, 16-Jan-07, to lugnet.robotics.nxt, lugnet.robotics)

Yes, you can use an electromagnet with the RCX. Depends on what you want to do with it, but it should work. The device from a disk drive might be a 12 volt device, or 5. The RCX puts out around 8-9, so either way the device isn't drawing the correct (...) (18 years ago, 16-Jan-07, to lugnet.robotics.nxt)
