Powerful Automatic Tennis ball launcher – 30-35 meters!

Designed and printed this powerful and automatic tennis ball launcher for our overly active German Shepherd. Because he has enough space to run around here it could be quite a bit of a powerful ball launcher. And that’s what it has become! The GIF in the Pictures shows the first test. (Without housing still) That was about 10-12 meters but after a few minor adjustments it now shoots consistently about 30-35 meters. Parts list with internet links, electrical diagrams and Arduino code are all in the folder. If you still run into problems during the build, you can always contact me via my e-mail. I added my email address in the top line of the Arduino code.
