Hackaday Prize Entry: Hydroponic Garden Control

[Todd Christell] grows tomatoes in hydroponic buckets in his backyard, and recently he suffered a crop loss when a mechanical timer failed to dispense the nutrient flow as directed. He decided the solution was to add a sensor array to his home network.

[Todd]’s home automation setup runs on a Raspberry Pi loaded with Jessie OS and Node-Red, with Mosquitto as his MQTT message broker. With a sensor network in place, [Todd] would get updates on his phone alerting him if there was a problem with the pumps or if the nutrient bath was getting too low.

The proposed hydroponic …read more

Hackaday Prize Entry: Modular Rail Lighting

When operating any kind of hydroponic farming, there are a number of lighting solutions — few of them inexpensive. Originally looking for an alternative to the lighting of IKEA’s expensive hydroponics system, [Professor Fartsparkle] and their colleague prototyped a rail system that allows clip-on LED boards for variable lighting options.

Taking inspiration from wire and track lighting systems, the key was the 5mm fuse holders mounted on the bottom of the LED boards. Snipping off their stopping clip makes them easy to install and remove from the mounting rails. The rails themselves double as power conduits for the LED boards, …read more
