An Experiment to Combine Lego and Snap Circuits

Completed instructions to vary the speed of the Snap Circuits motor using the modified transistor and variable resistor circuit.

Found a circuit in the Snap Circuits Motion manual to vary the speed of the Geared Motor (Project 49 on page 34: http://www.elenco.com/admin_data/pdffiles/753134.pdf). Will post instructions on the circuit build as time permits.

Still looking for suggestions to attach construction toy gears to motor axle. I you, dear reader, have an idea for a solution, please comment.

I think the next thing to do is to control the speed of the spinning mirror. This can be done mechanically with different sizes of pulleys.
