Connected Fish Feeder

prusaprinters

<p>This device is actually being used on 7 aquariums with fish !</p><p>I designed this fish feeder to have a large food tank, and an accurate quantity dispensing.</p><p>You can program up to 6 dispensing per day, easily could be increased but don't overfeed your fish ;) and chose the quantity for each.</p><p>You get a notification alert on your phone if the module disconnects (power outage…), or if no food was actually dispensed.</p><p>The firmware and Gerber files for the PCB are available here: <a href="https://github.com/reivaxy/iotFeeder">https://github.com/reivaxy/iotFeeder</a>, but you can probably fit an ESP8266 wemos D1-mini board + stepper driver board instead, but don't power the stepper driver from the ESP 5V pin, you would fry the onboard regulator.</p><p>I'll add info on how to build the whole stuff.</p><p>The back was printed using two colors (PRUSA MMU2s) to show reverse and forward arrows above the respective push buttons.</p><p>&nbsp;</p>
