Approximately 4 years ago I started a thread about my building a gem mount. I got the bottom half build for the prototype and was working on the stepper motors with a worm gear. I am now working at home because of the virus. KI was using the parallax propeller 1 chip for the micro controller. I am now with propeller 2 wow you cannot believe how much power it has. Please look at it. Since I now have a lot of down time. I am going to finish the ptrototype based on the unit built by this nice gentleman who sent me his schematics:
