For now this is an overview of hobby projects, systems I want to build, and a few coordination problems I think are worth solving.
Open-Source Infrastructure Ideas
Generic DNS Seeder in Rust
I've been sitting on this idea for a few years now, need to get started on it. Would be generic for any network (Bitcoin, Dash, etc.) and configured via command-line options and/or config files.
Hardware/Firmware/Embedded
Weather station
Ultra localized weather readings, temp/humidity/barometric pressure, can also include wind speed/direction via hall effect sensors + wind vane, raindrop sensor, etc. if desired
DIY "Smart" Thermostat
Our thermostat is old, needs replaced. Why not build one myself and customize to my heart's desire? Might use either STM32 (my preference) or ESP32 (has WiFi/Bluetooth built in)
Garage Open/Closed Detector
Basic magnetic reed switch to detect open/close state
Mailbox Open Detector
Detects Light via Photoresistor, sends signal via 433Mhz or LoRa or similar. Know exactly when your mail is delivered.
Large-Scale Coordination Ideas
Abolish Time Zones
Time zones are an outdated artificial construct that cause more harm than good in the 21st century.
Convert USA to use °C
This is another ambitious effort to convince Americans to use the correct temperature scale by introducing double-displays everywhere that temperature is displayed, °F in large and °C smaller, and gradually scale down/up the different measured 'til they are inverted and eventually the °C is more prominent. Once ppl are used to doing mental conversions, we can eventually phase out the °F scale
