I made a game! Just a prototype but fully functional and ready to play for free thanks to @itchio.bsky.social 🎉
Pondering what the next steps might be to push this project along further.

ECS pattern, where have you been my whole life?! Currently playing around with some roguelike game programming in C. Might even finish something this time.

Coding some sensor firmware with ESP32 IDF took a few weeks longer than I thought it would, but finally all working (again). Telling myself the learning experience was worth the effort. #esp32 #electronics

I'm learning that every day is 'technical debt day'. It's just that some day I'm actively reducing it and other passively increasing it.

More tests: x2 devices reporting overnight. One on my desk and the other by a window that gets morning sun. Graphs made in #Grafana. Devices are ESP32C3, #Sensirion sensors and running #Micropython. Testing a smaller battery, hence diverging battery readings. #electronics #ESP32

Temperature and humidity sensor development continues on the software front. Sleeping the hardware for 4secs between reads yields ~34.5 hrs of life on a 1100mAh battery. Going to try caching data locally and connecting/sending across the network less often next. #esp32 #micropython #electronics
