What kind of project are we talking here? Is this to do some sort of pseudo CNC unit?
I would look at using a cable that they used to use for audio on DVD/CD drives. I think that I may still have a couple of the cables laying in a parts Bin I keep in my workshop. I will check when I get home Sunday.
The wire is around 18 gauge.
The other is the flat pin cables that are used to connect the USB ports on the front of computers to the mother board.
I am sure there are a few like me who still have some of this stuff stuffed into a box somewhere.
Ren: Now listen, Cadet. I've got a job for you. See this button? Ren: Don't touch it! It's the History Eraser button, you fool! Stimpy: So what'll happen? Ren: That's just it. We don't know. Maybe something bad, maybe something good.
