non electric clock drive
Hi all, where we live in the Philippines electricity is at best a 50 - 50 proposition. Brown outs, voltage fluctuation, and just plain old lousy maintenance and the occasional falling coconut taking down the line is our world.
I would like a tracking system for my DOB but I need one that's power source is either a spring or falling weights.
Can anyone point me in the right direction?
Brian
