OK here is my dilema, I have searched for hours online for plans for a motorized double arm barn door mount for super long exposures so I can try my luck at some astrophotography.
I ran into a problem, I know nothing about stepper motors (still don't know anything about them except that they are small motors and I don't know how to make them go 1rpm rather than 2,000,000,000,000rpms (exaggeration of course).
I know nothing about circuits or how to alter them and thats mostly what I come across. And the only 1 rpm motor that I can even think of would be a clock second hand, but I know not of a second hand on a clock with that much muscle behind it (enough to lift a few small boards, a Canon EOS-350D, and a 70-300mm lens attached).
So what I am asking, is:
A) Can anyone know of a beefy little 1RPM motor that is easy to fabricate if I absolutly have to
and/or
B) Can you point me to a link that may help.. I have found tons but send me one that worked for you..
and/or
C) Is it worth going through all the trouble to make mechanical? should I just go manual? |
