Pickleball Tennis Tutor Ball Launch Warning LED Hack

I’ve always found it difficult to practice good form on a ball machine because I couldn’t split step before the ball comes as I would when I typical hitting partner starts his swing. I solved that problem with a snap action micro switch ($3) and some red and green LED strip lights intended for marine navigation ($10). I had to cut a small hole in the plastic and used the natural ridge in the opposing ball cup. This is a tennis tutor that was converted for Pickleballs. See my other videos if your curious on how to do that.

Hey Jacob, great work on the conversion and all the mods! I have a Spinshot Player tennis ball machine I want to convert and want to try printing your wheels to see if they fit. What material did you use to print your wheels, and what infill?
