If it blinks, beeps, senses, moves, or computes, someone here is probably into it. A sampling of what turns up at meetings:
Microcontrollers
Arduino, ESP32, RP2040, STM32 — the little brains behind most projects. Reading inputs, driving outputs, and talking to the world over Wi-Fi or Bluetooth.
Single-Board Computers
Raspberry Pi and friends — full Linux machines for home servers, media boxes, camera rigs, retro emulation, and anything that needs more horsepower than a microcontroller.
LEDs & Displays
From a first blinking LED to addressable RGB strips, matrices, e-paper, and OLED/LCD panels. Light, color, and little screens.
Sensors
Temperature, motion, light, distance, air quality, IMUs — measuring the physical world and turning it into data you can use.
Motors & Robotics
Servos, steppers, DC motors, drivers, and the mechanics and code to make things move, roll, and grab.
Retro Tech & Retro Computing
Vintage machines, 8-bit micros, old peripherals, and giving classic hardware new life — or emulating it on new hardware. Want to talk shop with assembly programmers? You'll find them here.
Electronics & Soldering
Breadboards, circuits, PCBs, and the soldering-iron skills to build and fix them. New to the iron? We'll help you get started.
IoT & Home Automation
Connected sensors and devices, dashboards, and automating your space — locally or in the cloud.
AI at the Edge
Running models on small hardware — vision, audio, and ML inference on microcontrollers and single-board computers.
