hardware is intricate! nice!
I have a request: kindly print the segments with luminous color. mount hardware inside a box, then light the front portion with UV leds ☺
I have finished designing rear cover and now printing it. It will block the light leakage through the segment hole.
Very nice! I've been meaning to try designing something similar, I love these mechanical seven segment displays.
Beautifully done!
Very nice 👍🏼 for V2 I wish for simultaneous change of all digits 😎 Thanks for sharing 👍🏼
Actually micro:bit has only three PWM (pulse width modulation) generators, it can not control four servos simultaneously. If we use some auxiliary servo controller board, it would be possible. It also draws much current (power) so strong power source would be also necessary.
@@shiura Thanks for explaining the limitations and how you overcame them 👍🏻
This looks amazing! Very well thought out!
holy cow this is genius, well done sir
Very clever!
How have your servos held up. I find that clocks that use servos don't last more than a few months because the servos for the minute segments fail.
Yes such kind of servo has potentiometer (variable register to acquire the current angle) and it is not durable enough. Stepper motor is more durable so it would be nice to replace them but I have not designed yet.
@@shiura I thought the same thing... would like to redo the design with stepper motors... also would be much quieter.
Hi, what type of servos can i use? And does the servo need to rotate 360°?
Please use SG90 type servo (I recommend genuine SG90. There are a lot of compatibles.). Owing to gear ratio, the servo rotation angle needs to be 180° .
Hello Microbit processor is a lot of money here. How to do it with Arduino?
If it is capable of 4 servo motors, it is OK. It should have some interface (a few tactile switches) to adjust the time.
