Meshcore solar repeater up! 📡

Measure once... Print five.

Teenager: Can I get a computer. Me: We have a computer at home. The computer at home...

Down 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.

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

New project! 🕹️ Joystick using American style Happ compatible components. Pico 2 for the controller. Easily connects to RetroPie.

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.

Another fun one! Credit: www.printables.com/model/36068-...

Nostalgic print! ⚔️🛡️🐉 Design credit: www.thingiverse.com/thing:4677561

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. ollama.com/library/deep...

Diy cabinets in a 1949 home require some serious shimming.

Found in the office. Published 1999. Still has the unsealed CD-ROM!

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!

I learned a new skill today 🎄 Ender-3 V3 SE

Awesome!

Literally shipping software! Epaper marine weather station 🎁🎄 #arduino Code in comments.

That time of the year for addressable LEDs. #NeoPixels code in comments.

That time I ran llama 3.3 70B on on my laptop CPU just to see if I could. Clocked a blazing fast half a token per second. #ollama

Full color Asteroids! Esp32 and TFT SPI display. Code in comments.

Dance party!

AI + Mini Pupper 2 workshop at AWS re:Invent

Simulated ball roll using device tilt. Arduino Nano esp32, OLED ssd1306, mpu6050 accelerometer.

The original. Parts easily obtained off Amazon: esp8266, OLED ssd1306, and a button. Code in the comments.

Asteroids on esp32 and OLED.

We got some serious elementary school science going on here.

Running ollama on a Raspberry Pi 5. Insane how easy it is to set up a local AI containing an entire encyclopedia of knowledge. 4 tokens per second for Llama 3.5 3b.
