Dear Roy, very interesting suggestion, I am searching for a clockwork motor, already visit several old mechanic shop in my town Dhaka… lets see but i think its not so easy to findout something like that now but I found a Photocopy Machine DC motor with a gear box (made by strong plastic), it is available in nowadays electrics market… just I need to control the motor so i am planning to make a voltage controller circuit to control the motor rpm… its seems to me easy to build an alternative cheep tracking system for anarchic astrophotographer :), i’ll let you know the update, if it is worke then I’ll write an article how to build in our BAA I&I section… thaks for the clockwork idea it helps me to findout the solution.
