Quartz-movement based perpetual calendar clockshiura2023-04-19 | A 3D printed clock with a perpetual calendar mechanism that correctly handles all types of months, including February in a leap year, has been developed. Despite the weak torque of a quartz clock movement, an improved mechanism has been designed to mechanically realize this complicated function.
* More sensitive for light payloads (2g/div) * Max 500g payload * Tare function (subtraction of the weight of containers) * No spring (easy to make without special parts) * Easy to calibrate
- Print-in-place : Just print, and you are all set. Assembly work is not necessary. - Magnet : It holds the driver bit securely. Steel screws could be held at the tip of the driver. - Durable ratchet mechanism : Tapered ratchet gear makes it not only easy to print but also sturdy operation. Pressure from your palm to the screw bit effectively aligns and locks the ratchet gear. - Double sided : It can be used for both rotations (CW and CCW) by flippingWatch Winder Clockshiura2023-05-16 | A watch winder that displays the current time acquired via WiFi. The rotation of the second hand also winds the mechanical watch. When you pick up the watch to wear, you can confirm that the time displayed is correct.
It has two modes: normal mode, which only shows hours and minutes (20 rotations per hour), and busy mode, which additionally displays seconds (200 rotations per hour). By pressing a button, you can switch between the modes. It is also possible to program it to display seconds in the morning.
Gravity-powered mechanical timer for fun. This cylindrical timer rolls down the inclined plane very slowly, at a rate of 20cm per minute. It is inspired by traditional Inclined Plane Clocks and is very similar to the popular clock mechanism Tourbillon, except that in this case, the outer cylinder rotates instead of the inner clockworks (escapement).

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.
