good idea about the optical system, but the problem with the reciever part
of the system is how do I power it? I was thinking of it before but if you
hit a bettery with a streamer from a coil... keep in mind that I have only a
very limited amount of space (like 10cm) under the primary and the secondary
cannot be removed from the base - all batteries would have to go outside of
the assembly!
