This is a battery powered FED device for training rodents in home cages. FED was developed to free researchers from expensive and rigid behavioral testing equipment, and allow them to do their experiments wherever they'd like - in dedicated boxed, in the home cage, or even inside other scientific equipment. Importantly, FED3 is open source and new sensors or code can be easily added to change its function.
The device runs on an Adafruit Adalogger M0 Feather board, which also includes a microSD card slot for recording behavioral data. The hardware include two "nosepoke" beambreak sensors, a beeper, a multi-color LED strip, a pellet dispenser, a BNC output jack for synchronizing with other equipment, and a screen for providing feedback to the user. See logs for info on the build, costs, etc. And as always, feedback is welcome!
