Knock on frame to activate mirror

[kiwimon]

HI guys,

I’m building my first mirror and so far all the module that i need have been install successfully. Just wondering have anyone add a vibration sensor to the pi so that a knock on the glass or frame wake the screen up?

@kiwimon No but I have a clapper I am going to use.

It’s a nice idea. Maybe it even works withe MMM-PIRsensor module. Just give it a try. A quick Google search leads to a Pi compatible SW-420. They cost a few cents on AliExpress.

Really cool idea. I’d just go with an accelerometer
sorry just found that with a really quick google search on a German site, but you’ll get what I mean :)
