Powering the Laser: Part II
The next thing that needed to be done was get a power supply. I was using 9v batteries for a little while but they don’t last very long. I’ve needed a variable power supply for a while, but they were always a little out of my price range. So I went to Electronic Goldmine and picked up a nifty 0-12V DC power supply kit for a little over $11.
I haven’t decided if this is going to be attached to the CNC machine or if I’m going to build a constant 12v power supply. If it’s going to go to the CNC, I’ll have to stick a relay or transistor in there so it can be turned on and off by computer.
I will have my own pics up soon instead of all these product photos!
