Ask and ye shall receive! I'm tacking a GPL 3 license to it. The plugs that play a sound after a delay won't work on Windows because I use fork(), but I don't use Windows because fuck Windows. It uses mpv to play sounds, but that is easily changed. AMA.

Dude honestly the Volcano rules. I've had mine almost 20 years now and I've had a screw rattle loose and the plastic airflow button broke ($10 part) and that's it. I also bought a Crafty+ and I hardly ever use it. The Volcano is definitely smoother and I think hits harder. Plus you can see how heavy your dose is about to be as the bag fills. The power plugs I bought came out to like $10 each I think for a pack of 4.

There's not much to see. I made this cool mollyguard for the power button out of a clear bud capsule. This way nobody flips the switch when I expect it to stay on all the time and I can see the power light through it.

Lemmy is failing to upload my images, so here's 2 links:

Volcano (excuse the mess, I found I spilled some inside last night and tried to clean it lol)

My dinky menu I use for it sometimes

It's actually not open on the internet, it's only on my LAN. I ssh in to access it if I'm out which is rare so it's very safe. These Tasmota plugs are great because they use Free software firmware (which I updated from the web, not the manufacturer), I trust them a lot more than any other IOT device.
