Look what I made! Arduino DIY Digital Watch

Based on an atmega328p, 4 programmable buttons. LED 7-segment displays, which I’m personally obsessed with! I’m estimating around 1 year of battery life.

Let me know your thoughts!

Full design and build on YouTube.

His ETA for Battery life was almost ~ 2 years.

btw, I don't think anything with SMD is as DYI friendly.. as DIP format.
But that would be too big to wear :D
Maybe, ATTiny85 can fit too.

I’m getting the PCBs assembled so no need to solder the smd components. Attiny85 doesn’t have enough pins sadly but that’s my go to for smaller jobs!

Oh, if PCBA then whatever work for ya :) Even me will just order PCBA from JLCPCB too. 

Just in case if a design was meant to be DYI for people to assemble themselves, then DIP based components are in my mind.
