Hi Michael!

Boy, you're just about the only one interested in my designs anymore , I used to spur more interest here!

Anyway, the answer to your question is I use an infrared emitter / receiver sense the ball bearing.  When detected, a small coil is energized with a single pulse from a circuit I designed to provide enough attraction to send the ball bearing up the hill, where it coasts down to the sensor again.

Thanks for your interest!

Cool. Mark is a great guy. He has posted a number of my projects to BoingBoing and interviewed me once for his news letter. 

Don’t understand why there is not more interest here. Your projects rock! People on Instructables sure think so!
