I want to make a perfect round hole of 16mm in a pinpong ball.. but i think just drilling it wouldn't go real nice. does anyone of you now what's a good way to do it? perhaps using a dremel?
the idea is to desolder the 2 sensors of a parralax ping sensor and put them into 2 pingpong balls making real nice looking eyes.
hmm.. let's call it "Parallax PingPong)))"
