CNC Mini-lathe


Given my obsession of CNC projects, I’m surprised that we haven’t mentioned this project before. [Dave] put together an excellent site about his CNC converted mini-lathe. (The same on that I’ve got) He built a pretty simple stepper controller to drive it. Since the lathe only needed two axis motors, he drove the steppers with some mosfets that he triggered from a parallel port. The site has been around for a while, but I thought you guys would enjoy a classic hack like this one.

HackIt: New uses for old CRT monitors


[atrain] wants to know if we’ve got any thoughts on things to do with old CRT displays instead of giving them away or recycling them. We’ve seen pic programmers and oscilloscope projects, but even I’m curious to see what you guys have to say.

So, got a better idea? Let’s hear it.
