Figuring out KiCAD a bit better now, updated lightning detector PCB. Now with a JST-PH 3-pin connector.

This is kinda fun. #embedded shenanigans. Maybe I should place an order for these.

I can't quite figure out KiCAD (I need to practice more), but LibrePCB got me covered. A little lightning detector sensor, let's gooooo

Hell yeah! My #tui app for monitoring lightning detection data from my Pico W board is working nicely. Working with #bevy for the ECS/app structure and #ratatui for the rendering has been pretty nice. Still a lot more features to implement.

Success! Yak shave complete. I can now discover my lightning detector on the network via mDNS Service Discovery. Now onto other things...

Finally back home, and now I can test my lightning detector with my redone pico w code:

Embassy makes #embedded programming so... fun & cozy! Things just work.

Nothing cozier than a kitty sleeping next to a wood burner in the winter. #cat #cozy #catsofbluesky

The fun part of open hardware is instead of using the provided firmware, you instead write your own firmware! *In Rust~*. And then you get the warm fuzzies when it all works. Why am I like this?
