For everyone in the world whose heart has not melanise and shriveled beyond repair , nothing boosts your mood quite like a raw family summation in the form of a detent . That is , until you have to wake up at the crack of dawn to allow that needy , opposable - thumbless mongrel out . But unexampled dog proprietor and Raspberry Pi enthusiast David Hunt has set himself up a highly originative solution : a door that automatically unlocks at your domestic dog ’s barque — or as he ’s dubbed it , Pi - Rex .
Trying to make this DIY doggy solvent as easy as possible , Hunt eschew any potentially expensive camera equipment in favour of a gaudy noise detector racing circuit , which was help by the attached Raspberry Pi and motor driver PCB circuit . Once the tiny computing machine notice the barque , the circuit drives the actuator to unlock the door , and a simple pulley organisation swing the door exposed to break the giant can that is the world .
Hunt describes the process :
I beak up the audio detection circuit in Maplin as a DIY kit for € 9.99 , the kind of one where you get all the components and a PCB in a traveling bag , and solder them all together . It took about 30 minutes , but worked perfectly , I could skin , and the light-emitting diode ’s would fall as I bark . My family intend I was pass away insane when they heard me shit dog dissonance in my workshop .
A Raspberry Pi in the centre , a motor driver PCB to the left . I used this because it easy permit me to send 12 volts to the actuator in either polarity , for pushing or pull the door dash . The PCB on the right is the audio espial circuit from Maplin . And at the bottom is the 12V actuator . The small veroboard PCB is just a electric potential breakout with GND , +5v and +3.5v , to make the wiring easier .
All the wiring is done with dupont connectors , 0.1″ ( 2.54 mm ) pitch , just like the Raspberry Pi GPIO heading . I got a crimp prick off eBay , as well as a a few twelve clean connectors and a roll of distaff crimps . Make cable up this kind of labor very leisurely , where you do n’t want to solder everything into situation .
So while it will for certain take some technological knowhow , the project really is n’t all that complicated . Hunt even gives you all the code you ask to make a Pi - Rex for your very ownover at his website . at last , Fido is innocent to assuage himself at will — so you’re able to get some sopor .
