A DIY CNC pendant made by Bob Davis. He wrote a post on his blog detailing it’s assembly:
Last night I finished building my DIY CNC pendant and tested it out. I still need to add a manual jogger to it someday. It is made out of an old Zenith TV remote control. The key is to have three position toggle switches. I have a lot of them laying around that were left over from another project. You can build this for about $25 or for free in my case because I used parts that I had laying around. It will be in my next book “Arduino CNC Projects”.
