Eptaora Hackaday Io This project was inspired by another similar project that i saw a few years back. i mostly rebuilt it completely and challenged myself to print it as small as possible on a standard 3d printer using a standard nozzle. the size was determined by the smallest screw hole that was possible. Smartphones are the easy solution, but if you want to show things off in 3d printed electromechanical style, then the seven segment eptaora clock from ekaggrat singh kalsi could be your next timepiece.
Eptaora Hackaday Io “eptaora” is the name of this clock, according to its inventor [ekaggrat singh kalsi]. the goal here was to make a mechanical flip segment display as small as possible, which meant starting with. This is a single module or a entire clock i made. this module can be used independently as a 7 segment display or can… this is a single module or a entire clock i made. this module can be used independently as a 7 segment display or can be daisy chained to make a bigger display. To make the experience fit your profile, pick a username and tell us what interests you. if it has a timekeeper, it belongs in this list! this project was created on 10 08 2022 and last updated a month ago. this project was inspired by another similar project that i saw a few years back. The clock consists of 7 segments which are driven by seven cams. the cam push the followers which in turn lift the segments at the right moment to display the digit needed. the modules work in pairs. the entire clock is driven by a attiny 84 and two a4988 stepper drivers.

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. 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. I used this to just study the mechanism. going up?
this was the first module i made but it was a lot larger .
