I decided to help my 2 year old son learn his colours I could either just use a book with pictures of colours or utilize some wireless charging modules i had ordered online.
This design takes these charging modules and uses them to power a ATTINY85 microprocessor chip that drives 7 WS2812B leds. It has a cycle of 7 colours that it goes through as the cube is placed on and off the charging block.
Cube is printed out of a lithophane specific filament but the rest is black PLA. It is driven by 5v / 2A power supply and can easily be used as a night light.
Fun little project, unfortunately i dont have an eagle PCB schematic for this one however i have learned that a zener diode and capacitor are a great idea. Lost a few modules due to what i suspect was voltage spikes.
Components:
1. ATTINY85 DIP chip
2. Wireless Qi Receiver (https://www.aliexpress.com/item/32852366953.html?spm=a2g0s.9042311.0.0.27424c4dsO6Q5M)
3. Wireless Qi charging Transmitter (https://www.aliexpress.com/
