YouTuber Alexander Gorovenko built this futuristic watch using some sleek micro 5×7 dot matrix displays. Like an iced out Rolex, this watch is instead covered in displays.
Prototyped on a raspberry Pi Pico, in the build he opted for a STM32U083kCU6 chip. He designed a custom flexible PCB to comfortably wrap around the wrist. Great video and project, especially for his first one!
The main parts I used for the watch are as follows,
- The display, which is the HCMS2901 (A more 3.3V friendly HCMS3901 exists now and is easier to find new). I got my displays on eBay.
- The microcontroller, the stm32u08, offers a real time clock and USB programming.
- A vape battery.
- STC4054 LIPO charger IC.
- Generic 3.3v LDO regulator.
- and several capacitors.
I got most of my parts from Digikey but many places sell most of the parts I bought.
