NECTR 2021

 So I went to NECTR this year and decided to contribute something to the art world. Since I'm such an egomaniac who's constantly clout chasing, I'm making this guide.

Legal disclaimer:

I'll be treating the propane 'poofers' as a blackbox device. You shouldn't be coming to me for advice how to create them. I don't know how, and I don't want to be held responsible anything you do involving flammable (inflammable? WHAT A COUNTRY!) gases. This guide is more for me to remember what the fuck I did rather than having someone replicate it it. Unless you already have poofers then by all means copy this. You already did the hard/dangerous part. If you don't, that sucks dude they're great.

What will I need?

Poofers, and a couple hundred gallons of propane and a place to set up. In fact this should be one of the last steps:

Raspberry Pi (I used the 3B+. Running Python 3) with a Relay hat

Rockband drum set

 Okay. That's it

Setup:

I made a fun wiring diagram for how you should connect them

But it breaks down to Plug in the USB Controller

Wire the poofer solenoid valves to relay board and power it using a waterproof connector. Power solenoids with 12V, Pi with 5V

What about software? Oh right, that already needs to be on the Pi

 

Here's the commented code:

Pretty much boils down to to:

 Connect the to the drum set and relays, if one pads is hit then tell the relays to close/activate. The up/down arrows on the d-pad adjusts the amount of time each poofer is activated for. This is so you can tune each one to make a specific sound repeatably. The actual sound is additionally adjustable by the pressure and distance from valve to pilot light. A light tap is the same as a heavy bang. A drum roll quick enough will just keep the flames shooting

So what does all this get you?

Some annoyed neighbors.

Thanks for checking out my guide!
