The hardware

This is a cheap CNC milling machine that I bought of Amazon. I covered the wires with some plastic wire covers I bought for my first kit car (now that would be 20+ years ago!), and fitted a camera to it:

The camera is a USB camera that came with a manual pick-and-place machine that I got off the company that made me redundant 2 years ago (they allowed me to buy all their gear at knock-down prices). The camera didn't work terribly well with the pick-and-place machine, so it had been languishing in a box for a while.

It has a 19mm body, and I just knocked up some mounts for the camera that are held into the Z-axis of the CNC machine body. It doesn't move up and down with the drill - just side to side and front and back.

I also made some clamps for the PCB, since the CNC machine didn't come with any (slightly annoying).
