Waveshare Rectangle Electronic Clock for Raspberry Pi Pico with Accurate RTC and Multi Functions LED Digits Open Source Programable

I wanted a clock that would indicate every time 6 minutes went by, a sort of clock with an automatic pomodoro kind of function, to help with time recording. I couldn’t find anything on the market that had that but came across this as a programmable possibility. I adapted code on GitHub by someone called astlouys, which takes the functionality way beyond the stock firmware from Waveshare, and adapted it to include the functionality I wanted. Great result and now the clock scrolls every 6 minutes that 6 minutes (ie a unit) has passed. It could beep too but I thought that would just annoy me; might be useful for doctors doing GP consultations I suppose So I’m very pleased. The product itself is pretty good quality, shame it’s not available in other display colours though. It uses micro usb for power, with very little power draw.My tip: don’t waste your time trying to program the pico using a Mac, use a Pi 3 or equivalent instead, far far easier and would’ve saved me weeks of hair-tearing if I had realised that from the start.

The hardware the great. This has been running for several months without any issues. The documentation for C and example code is far more robust that Python. I bought this as a Python project and it was a good learning experience at the time. The Python repositories on GitHub are a bit stagnant, but allow you to make a functional clock without much fuss.
