Want to make cheap quartz clock turn paper gear. Need more torque...how? Answered
I followed one Instructable to create 4 different size paper gears and I've got a cheap quartz clock that I've stripped down to just the guts. Inside the clock was a small circuit board with quartz crystal and smaller plastic gears that move the hands of the clock. I'd LOVE to make the part of the clock that moves the second hand move the small paper gear that will then move the other 3 bigger gears. I've done a test fit but the parts of the clock don't have enough torque to cause the smaller gear to move the bigger one... ideas?
I was thinking I could wire the quartz mechanism to act as a switch to power a small motor on/of each second. Will that work? I know that the voltage necessary to power the quartz crystal is really small, so I might be able to get away with powering the small motor AND quartz mechanism with the same AA battery, I could do separate power sources though...
