[quote]Waking up at 5:30 in the morning. [Mark Stead] didn’t like the idea either when his chickens started crying to be let out. One simple solution obviously is to [del]eat the chickens[/del] build an automatic door opener. The mechanism starts out with an old style mechanical alarm clock, add a geared motor with some creative switch work to pull open the door, weather proof the entire thing, and done. [Mark] even modified the setup later to work with vertical doors. No MCU required for either.[/quote]

Giuro che mi dispiace non avere un pollaio per costruire ‘sta cosa…

Avevo pensato di fare qualcosa del genere per il gatto (in stile [i]automatic feeder[/i] su BTTF), ma la mia fidanzata ha bocciato l’idea.
