A self-managing hydroponic rack that watches every plant with a camera and keeps water, nutrients and light in range automatically. Built on its own Arduino VENTUNO Q. No experience needed to join.
Indoor growing fails from missed watering, nutrient drift, and disease spotted too late.
Grow two full lettuce and basil cycles with automated pH, nutrient and water control, and flag stressed plants from images before a person notices. How it uses the VENTUNO Q: an overhead camera measures leaf area and yellowing per plant; the MCU runs pumps, lights, and pH/EC control loops in real time; a local LLM keeps a daily grow log and answers "why are the leaves yellow?" from sensor history. Safety: water near power. 12 V pumps and sensors, GFCI outlet, drip loops, lights on a timer with thermal cutoff. 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.
