EPTAORA

This prototype used 4 modules with a complex carryover mechanism so that the entire clock could be run with just one motor and one motor driver making the electronics simple and compact. But this made adjusting the time very slow and tedious. Hence this method was dropped for the more simpler approach of using 2 motors and 2 drivers.

The second module was to make it really small and to test the carry over mechanism

This was the first module I made but It was a lot larger . I used this to just study the mechanism.
