Hmm.... I did not boast her about my latest #keyboardio Model01 trick here, did I?

Guess I'll fix that after a bit of sleep. It's funny.

I completely forgot about this trick, until someone on the #keyboardio Discord brought up Focus the other day. Not even sure if it's a "trick", really. It's more like an overengineered contraption.

Anyway, lets get to it! First, lets look at the circumstances that lead to it. This'll take a few toots.

I work from home, with two unruly 4.5 year olds, who love each other very much, but also want to murder each other every 10 minutes, loudly, and they both run to me to complain about the other.

They are technically in Kindergarten, but with the Pandemic around, and the kindergarten not being the safest of places, they've spent more time home than in there since they started going last September.

So home is rather noisy.

Thankfully, I can lock my door, and have very good noise cancelling headphones, and loud metal music goodness to blast into my ears to shut out the world while working. I also work best with music in the background.


However, there's a bit of a problem: with the door closed, headphones on, phone muted, notifications hidden, my wife can't reach me either.

That's a problem, because if she doesn't reach me, I'm not eating, and if I don't eat, I'll be both grumpy and tired, and will eventually end up in a hospital (been there, done that when I was like 13: I forgot to eat, too busy with stuff, stomach hurt, school called ambulance, etc - but that's a different story).

So I do want to let my wife in. How?

The door is locked from the inside, and while we tried that I take the key out, so she can open it with another, that didn't really work out. Too much effort and time spent on boring things. I'm not good at boring things.

I don't hear her knocking, either, because, well, metal music blaring into noise cancelling headphones shuts out everything.

What do we do? I'm a hacker, I have a number of gadgets, and I'm not afraid to use them.

So now I have a Raspberry Pi near the door, a microphone set up at my wife's shoulder level, and a small tool on the Pi that checks noise levels on the mic, and when someone's aggressively knocking, it sends a signal to my PC.

On my PC, I have a small tool that waits for notifications from the Pi, and when the Pi says it's knock-knock time, this tool will open a serial connection to my #keyboardio Model01, and tell it to: led.panic.
