Down the meshtastic ๐Ÿ‡ 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.

I may have gone a little overboard creating Meshtastic nodes during the recent Texas freeze. ๐Ÿคท

Disco 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.

deepseek-r1 DeepSeek'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.

The 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.

Would love to know more for how to get ollama running on my Pi5 with an external GPU.

My #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.

Did 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!

Female DuPont with a short wire connected to the breadboard. I prefer solid, not braided wire since they stay put. The joystick is just hot glued onto the bread board. Surprisingly solid!

Breadboards stuck to a square of model birch wood. Pretty strong and light actually.
