Any Doctor Who fans out there? [Pat] just sent us his project on home automation… using a Sonic Screwdriver!
Ever since he pre-ordered his Raspberry Pi at the beginning of February 2012, he knew he wanted to try his hand at home automation. The easy way was to use X10 outlets, but at $20+ an outlet, it’s not that affordable. Instead, he managed to find a rather cheap system on Amazon — RF controlled outlets. They only cost about $35 for a 5-pack!
It’s a very basic system: five outlets with five buttons on the remote. All he had to do was wire up the Raspberry Pi to simulate the button presses by setting the GPIO pins high, and presto, a simple but effective home automation setup.
This is where it starts to get fun. Unfortunately, unlike a real Time Lord, [Pat] didn’t build his sonic from scratch. Instead, he found a universal remote control — styled after [Smith]‘s sonic. Add another RF receiver to the Pi, a web-based interface to extend the range, and bam, you’ve got one geeky, but awesome, home automation setup.
Stick around after the break to see it in action!
Kinda reminds us of my RFID Sonic I use at work! I prefer the Tennant edition though…
