A weatherproof listening station that identifies birds by song around the clock and publishes a weekly "who's singing" report. Built on its own Arduino VENTUNO Q. No experience needed to join.
Wildlife surveys depend on occasional volunteer walks, so seasonal changes and rare visitors go unrecorded.
Run continuously outdoors for a full season, identify bird species from calls, and post a plain-English weekly summary to the club site. How it uses the VENTUNO Q: an outdoor microphone feeds the audio input; a BirdNET-class classifier runs on the NPU; Gemma 4 writes the weekly summary; the MCU handles temperature, the enclosure heater and power monitoring. Raw audio never leaves the device. Safety: outdoor power on a GFCI circuit, and site permission from grounds staff before install. Solar power is a phase-2 stretch goal. No experience needed. If this sounds interesting, join anyway: every role pairs newcomers with someone who can show them the ropes, and learning as you go is the point.
Rebuild and modernize an Ender 3 printer by upgrading the MCU/control board and extruder components, installing Klipper firmware, configuring the printer, and tuning it for faster and more reliable printing. Additional mechanical or electronic upgrades could be explored after the initial conversion.
Repair a large-format 3D printer with a damaged build-plate carriage. Identify an existing replacement design or measure and design a new component, fabricate/install it, and recalibrate the printer.
Replace the main control board on a large-format printer. Determine hardware requirements, select/configure a compatible controller, connect motors, heaters, thermistors, and end stops, install firmware, and test the rebuilt system.
