On Thursday, I saw a really cool idea on ebay, an automated chicken pop door. £85 though was not for the faint hearted.
My friend Gary had some motors, but no knowledge how to do the timing circuits. My friend Ben however had that sort of stuff sorted. He’d been to a google conference and given an Arduino.
With a little technical know how and lots of electrical tape, an idea was born.
The door was 2×2 routed with a small hole for sliding. Pulleys made light work of the weight so a small servo motor could be attached. You do need a continuous rotation servo though.
Adding in the code and the Arduino in situ:
It works wonderfully. Total cost, about £50. So it’s a saving. Not including the wood and pulleys, but the £80 door wouldn’t have included those either.
