Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Need some opinions on a clock I'm planning to sell online that involves ESP8266
Honestly use should use the radio protocol instead. https://github.com/veebch/clock

TIL that a pair of relays makes an H bridge equivalent at higher voltages

Modify an old clock to use Radio (or internet) time
I appreciate the reluctance.... all the code and instructions are at https://github.com/veebch/clock
- The clock restoration code now includes instructions for a Pico W
-
Added code to make this work on clocks in the US using the WWVB signal (github link in comments)
All the code/ instructions are at https://github.com/veebch/clock. I've tested the logic but not against an actual signal yet (because geography)
- I added code to make old clocks in US work (WWVB radio signal)
- Using a pico to control a clock/clocks

Pico driving a wall full of clocks
Thanks! Pretty much everything you need is here: https://github.com/veebch/clock
- An old railway clock brought back to life with a Pico
- Pico and radio antenna = atomic(ish) clock

Casio G-Shock time sync radio
Thanks for those references! I wanted to see what an SDR radio time signal detector would look like, and looking for "DCF77 sdr python" pointed me in the right direction -> [0] and [1]
A bit unrelated question: there are many web SDRs that let you listen to radio frequencies/stations such as [2]. Are there web / Emscripten SDR decoders that run in-browser? i.e. a full browser listening + decoding experience? For example, decoding the DCF77 time signal, or even just morse code?
