tennis ball cannon

Only a truly lazy person would spend this much time and effort building an automatic tennis ball cannon for their wiener dog (or Dachshund for those that insist on the proper name). As you will see in the video, the device is able to sense when the dog places the ball in the chamber then automatically moves into firing position and shoots off the round for fetching. Obviously, YouTube user “lamgngo” was thinking about long-term laziness with this build. (YouTube)
