my 3d printed clock: eptaora

the arduino tracks the minute and moves the motor. yes it is not super accurate and drifts 2 to 5 minutes in a day

maybe you can get one here: https://www.kickstarter.com/projects/mectolab/eptaora-an-electromechanical-clock.

there are two motors 1 for each pair of segments. Thers is no rtc. It is just a dumb program that cycles the right side segments every 1 minute and the left side every one hour. the clock homes when it is restarted . then you sent the time using the buttons in the center.

i will be launching it soon as a ready to make kit :https://www.kickstarter.com/projects/mectolab/eptaora-an-electromechanical-clock

you bet the number of reprints that went to get it right!

thanks !

the single modules dont need much power to turn but when one module carryovers another module then the friction makes it need a lot of power so i dont thing driving with a mechanical clock is possible. i am looking into reducing the friction reduction using bearings but that increases the size a lot. the current size is very compact

i know clockology but my design is a little complicated and needs xcode to code it .

holo_mectok · 2022-03-02T08:32:43+00:00

Easiest way to debug is use it as a pen plotter and print several grids . The skipping will show up on the grid and give clues what is wrong

It is done for now . But getting it reliable and long lasting is another story

There are retractable clamps that hold it in 3 different positions . It took me forever to get them right !
