Digital Crazy Hours and Minutes - WiFi Sync Clock

Usually, intermittent motion mechanism such as Geneva drive is necessary to decrease the number of the motors of mechanical digital clock. Contrary, this clock has a constant mesh (permanently engaged reduction gear) between tens and ones places of minute numbers. The ratio of the reduction gear is coprime (7 : 10) and 70 numbers can be shown by one motor. The order of the numbers are not random but optimized to minimize the time to update the time. To show the current time correctly when it is powered on, not only the WiFi connection capability but also origin finding mechanism are necessary. This clock has an one-way rotation blocking mechanism. The rotors for minutes are stopped at 00 when it moves backward, but pass through there when rotating forward. 3D models and code are published in the following site. It needs large (30x30cm) 3D printer. https://www.instructables.com/Digital... https://www.thingiverse.com/thing:589... https://www.printables.com/model/4158...
