Alexa Killswitch

Using the ESP8266 to cut power to the Echo Dot

Similar projects worth following
One of the main reasons I bought an Amazon Alexa device is because you could change the wake word to "Computer" like on Star Trek. Unfortunately, that turns out to be a fairly common word in my life, especially when I'm on a conference call with the rest of the Hackaday writing staff...

After suffering though more embarrassing Alexa outbursts than I'd care to admit, I decided to put together a simple network-controlled relay which would allow me to cut power to the Dot by sending a UDP command from my desktop. In addition, with the ESP emulating a Wemo Smart Plug, it's possible to craft a Routine which gives Alexa a brand new skill: the ability to commit suicide.

    I've uploaded the Arduino code for the Wemos D1 Mini. Seems to work well enough for me, but no promises it won't burn your house down. I should also mention that the state-of-the-art seems to have moved from emulating Wemo Smart Plugs to emulating Hue lights, so you may need an older (read, outdated) version of the library.

    STL files for the case are also available now. I've generated STLs for the lid both with and without the Jolly Wrencher, for anyone who might want to put their own art up there. If anyone is interested, I can put the OpenSCAD source for the case up as well.

    I'll be adding build details and images soon, as there's some modification required to the relay shield.

This one makes me chuckle... now if we could just get my google assistant to stop waking up on those conference calls we could all talk in peace. The future is weird.
