An interesting 3D printed clock that folds out flat or back on top of itself.

Recently I build a Cube clock that showed the time in the same orientation no matter what orientation the clock itself was in. This was inspired by the Lexon Flip Travel Reversible LCD Alarm Clock. One of the other thoughts that I had at the time was a folding clock.

This clock was designed based on components that I already had on hand; mainly the two 0.8in 4-Digit 7-Segment clock displays. Since the clock is in two parts, it made more sense to use two 4-Digit, 7-Segment display drivers (TM1650) rather than a single MAX7219 8-Digit 7-Segment display driver.

Most of the electronics are in the bottom or left hand section. Time is controlled by a Real Time Clock chip (DS1307) and it has its own battery so as to not lose any time when the main power supply is disconnected.”
