While on holidays I found in the studio of my father a small 1.54 inches epaper

Why not to add a tinyPICO esp32 as a controller and make a real epaper clock using a customized version of the clock firmware?

Me thinks is a cool idea and will be a cheap make, with the exception of the esp32 that is about 22 dollars. But is worth it!

The difference with cheap boards makes it a good choice:

• Deepsleep consumption with dotstar led Turned off is 0.08 mA
• Has 4 MB spiram (pseudo static ram)
• It’s super small!

Additionally we will need a:

1. Small battery
2.  3D printed case for the watch body
3. Watch strap

no buttons for now! It will be a button less digital clock

A small preview just with the epaper on my wrist :)

Do you like the idea? Would you walk with an esp32 in deepsleep mode on your wrist?
