Tried a plunger type thing, didn't work well, it had little power
cuz I wasn't able to pull it back very far, and when I put bigger
rubberbands on, it just tore itself apart.
What I did that worked ok was to put a 1x6 beam onto the side of
a 40tooth gear so that it swings. I then put another peg on the
gear and tied the beam to the peg with a rubberband. When the gear
rotates, there's a bar that the 1x6 beam runs into. As the gear
continues to rotate, the beam is bent backwards and the rubberband
is stretched more and more. Eventually the gear rotates so far that
the beam slides forward off the stop, and smacks the ping pong
ball.
This only gets a few feet of distance.

| The other thing I played around with was attaching a 1x16 beam directly onto the older faster spinning technic motors. I powered the motor straight off the train regulator, and holding the motor in my hand when it got up to full speed, I'd bring the (...) (25 years ago, 12-Jan-00, to lugnet.robotics)
