Lee Rehwinkel @leerehwinkel.bsky.social · 08/02/2026Down the meshtastic 🐇 hole we go. Testing a PVC mast connected to a flag pole. Clear line of sight to a downtown repeater! Next is to weatherize and power. That angle annoys me a bit though. 011
Lee Rehwinkel @leerehwinkel.bsky.social · 31/01/2026I may have gone a little overboard creating Meshtastic nodes during the recent Texas freeze. 🤷 021
Lee Rehwinkel @leerehwinkel.bsky.social · 21/12/2025New project! 🕹️ Joystick using American style Happ compatible components. Pico 2 for the controller. Easily connects to RetroPie. 120
Lee Rehwinkel @leerehwinkel.bsky.social · 06/07/2025Disco PCB... My first PCB design! Used through holes and generous spacing to make it as easy as possible to solder. I give it 50/50 chance of working. Check back in 2 weeks. 010

Lee Rehwinkel @leerehwinkel.bsky.social · 30/01/2025The most interesting thing about deepseek-r1 is seeing the 'thinking'. Kinda takes away the magic of o1, especially if you've been building out AI workflows using thinking tags for over a year now. ollama.com/library/deep...ollama.comdeepseek-r1DeepSeek's first-generation of reasoning models with comparable performance to OpenAI-o1, including six dense models distilled from DeepSeek-R1 based on Llama and Qwen. 020

Lee Rehwinkel @leerehwinkel.bsky.social · 16/01/2025My #rasberrypi system monitor service on Ubuntu. The fan is triggered by the CPU temp. Uses a transistor to shut off power when during shutdown. Code in comments. 120
Lee Rehwinkel @leerehwinkel.bsky.social · 27/12/2024Did battle with this 2019 iMac's security settings to boot from an external Crucial x10 SSD. The old HDD was a big bottleneck. Runs 10 times faster now! 000
