I am not very familiar with circuits and such. I am currently taking an electricity and magnetism physics class in school and so I am trying to inocorporate some of what we are learning. I'm guilty, I assumed "MC"14013 was an acronym for MicroControll but I guess I'm wrong. The reason I went with this one was because it had a parts list and somewhat detailed instructions. After looking at the 5th post, I was wondering, is there anyway you could explain this circuit to me. Thanks for the help and sorry for being ignorant on this subject.
I was a little surprised that you went for the most difficult to assemble option 1st, that's all.
If you look at posts 6 and 7 in the thread you will see zoomkat provided a list of the parts including radio shack catalog numbers and illustrated building the circuit. There are connections to the SSC-32 output, the battery (powering your electromagnet), and the load (your electromagnet.)
I would recommend buying a couple of the transistors as they can be destroyed by mis-handling or mis-wiring. I would also recommend upgrading the 1N4148 diode to a 1N4001 (RS cat number 276-1101) since your electro magnet will probably really abuse the smaller diode and if it fails the transistor goes next.
