Burning Man 2011: Duane Flatmo’s El Pulpo Mecanico

I had a lot of fun at Burning Man 2011, from the sculpture to the crazy art to the insane kinetic vehicles, the whole experience was something completely out of this world. With near 50,000 people out there in the Nevada desert it is impossible to see and experience everything the festival has to offer. I am positive there are several mind blowing sculptures or vehicles that I simply missed. That said, I have yet to hear a single conversation about Burning Man 2011 that does not at least mention [Duane Flatmo]‘s El Pulpo Mechanico.

Burning Man: Pirate Ship Sports Arduino Powered Flame Sails

The 2011 Burning Man festival starts in just a few short days, and with that we have an excellent mutant vehicle accessory that no insane desert dweller should be without. An Arduino powered fire cannon sequencer! [Paul] was asked by Lostmachine’s [Andy] to spice up the flame effects on their Priate Ship mutant vehicle and provide a cool looking fire show that represented the ship’s sails.

[Paul] tossed together a hand full of arcade buttons, switches, and an LCD display to control eight 12V Solenoid valves tasked with switching on various regulated propane sources that throw some brutal looking flame effects. The controller combines a Teensy 2.0 with a custom board that contains eight P-channel MOSFET circuits. Flyback from the coils is handled through zener diodes, and the IRFR5305s are sized quite above and beyond what is needed for the 12v solenoids. With the heat, dust, and chaos of the desert one can’t be too careful. [Paul] even tosses in RC snubber circuits just to prevent things from getting too out of hand. Of the twelve arcade buttons eight are used for manual over rides, and the remaining four arcade buttons, knobs, switches, and the LCD display are all connected to the Teensy to handle the sequencing. [Paul], sadly, will not be able to make it out to Burning Man to troubleshoot the sequencer, which is a cause for some concern throughout the build.

It just so happens that I leave for Burning Man this Friday, and have an 18″ by 18″ Hackaday QR Code that will mark my area, see if you can find me out there! Also check out a video of the sequencer controlling what is easily a 6 foot flame bar after the jump!

MIDI controlled fire drums

Using an MSA-T MIDI Decoder from Highly Liquid, [Rob Darman] was able to take the MIDI output of his Roland V-Drums and use that output to control fire shooting cannons, forming a setup that he calls fire drums. As seen in the video above, the response time between the V-Drums and the fire drums is pretty impressive. While this is by far one of the coolest things that we’ve seen controlled by MIDI, we’re naturally thinking about taking this to the next level; MIDI-controlled fireworks, anyone?

You may remember the MSA decoder devices from people wiring up MIDI drums to Rock Band.
