Interesting, so thats a slightly different design with mostly the same stuff. I’m working on mine and it seems to function with ~18v and 5v, but the motor control seems to be scatterbrained, sometimes it powers up stuck, other times it picks a direction and runs. I also notice only one led in the array is lit up, but since they seem to be in series im suspecting theyre all infrared.
Just brought in the oscope to confirm signals. Attaching a pic of mine.

The data scrolls into the serial monitor's input window, and I cut and paste it into a file. There is a similar unit on ebay that has a metal case vice the nice plastic on on my unit. Either it was an earlier model or someone made a replacement after the plastic one was broken. They were used in machine shops and the case looks home made..
