433mhz button home automation gizmo
« on: March 15, 2013, 09:24:20 pm »
I made a thing for doing home automation using cheap 'doorbell'-style radio buttons! https://github.com/Bluebie/digispark_ook_receiver I can write up some more info if people are interested in replicating it? It lets you use little wireless buttons to trigger bash and ruby scripts on a raspberry pi or something like that, which can go on to do whatever you like

Okay. It's kinda buggy at the moment - the digiusb keeps being crashed by INT0 when the line changes too quickly. I'm thinking I'll need to add an analog low pass filter before the pin, I can't think of a better way to do it in software - all my experiments failed. I'll try write up a bit of documentation or do a tutorial video thing once I have it working really nicely. <3
