I am looking for some small and cheap stepper motors with <10oz-in torque. Most of the steppers I can find from my regular sources/ebay are 60-1000oz-in which is far too much for my purposes (and will almost certainly push the cost up). Does anyone know of a good source for these types of motors ? Unfortunately I would like 6 (and potentially more) of them, so scrounging from old floppy drives is not really an option.

I've no idea what torque a wall clock mechanism has, but I guess it will be rather low-ish. Prices equally low (from $5).

  • \$\begingroup\$ of wall clocks I've seen that have that twitchy second-hand effect suggestive of stepping, I don't recall one that didn't employ a small solenoid type device instead of a motor. \$\endgroup\$ – JustJeff Sep 14 '11 at 11:10
