This is one piece I regret to have missed this year at Burning Man, however I certainly heard tales from any one who stumbled across it. [Christopher Shardt]’s Garden of Rockets consists of three kinetic fire art pieces with spinning propane rockets that you can control!
[Christopher] decided to incorporate his Burning Man 2010 project, 4pyre², which is a 12 foot pipe with opposing propane fueled rockets on each end. Onlookers can control the amount of propane fed to the rockets and twist the pipe they are attached to causing the whole thing to spin around like an out of control fire hose. Accompanying 4pyre² is PyreGoRound, and Pyroticulation which are two variants on 4pyre²’s concept of spinning rocket bars. [Christopher] was lucky enough to have his project materials funded by Burning Man, but added three thousand dollars (!) in propane to the mix out of pocket.
Check out a video of the project after the jump, and [Christopher]’s site for details and schematics.

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!

Maker Faire is a great event to attend not only because you get to see all sorts of cool designs and machinations, but because you can participate as well. At Maker Faire Bay Area 2011, maker [Brett Levine] put together a fun and interactive display he likes to call the DIY Flame Tree.
The concept is pretty simple, and he says everyone who participated got a pretty good kick out of lending a hand. Each participant was given a piece of copper tubing and allowed to bend, twist, and sculpt it to their liking before using a drill to add holes wherever they pleased. They were then allowed to choose where their portion of the project would be mounted on the existing tree.
With everyone standing a safe distance away from the display, [Brett] pumped it full of propane and lit the various sections on fire. In the video below, you can see that the display was blown around a bit by the wind, but we imagine it would look pretty awesome on a still summer evening.
Even if you’re not into this sort of art, you have to admit that it certainly beats a boring old fire pit!

[hpstoutharrow’s] new instructable is a neat idea on how to re-use those single use small propane bottles by turning it into an insulated canteen. Once the bottles are emptied through normal use, the safety valve is popped loose and allowed to vent. There are also comments on the article that suggest that the bottle be submerged to ensure all gas is gone, and we think that is wise too.
Once safe to work on, the bottom is cut open and the stem is cut off leaving a empty shell, a soda bottle is shrunk down by boiling water inside of it for a little bit, then is fit inside the propane bottle. The top of the soda bottle is held in place by an O-ring, the safety pressure hole plugged up and the whole thing is filled with spray “expand-o-foam” locking everything in place and adding insulation.
Though using a thermoplastic bottle as its liner does not invite hot beverages to the party, it seems to do the job just fine for cold drinks, and it makes for a interesting conversation piece out on the campground.
Join us after the break for a quick how-to video.

[Ben Nelson] turned his electric Geo Metro into a plug-in hybrid. But wait, where’d he get an electric Geo Metro? It seems that we’re one hack behind [Ben], who converted the vehicle to all electric back in 2008 using a forklift motor and some batteries. This time around he’s following the Chevrolet Volt’s example by adding a backup generator. Instead of going with a gasoline power he added a tank of propane and the generator from a Recreational Vehicle. This won’t put out enough juice to drive while the generator is running, but you can use it to extend your traveling range by pulling over for a nap while it tops off the batteries.
[Chris Marion] knew he wanted to play with fire, or more accurately with fireball spewing valves, but he need a good project in which he could use them. Inspiration finally struck and he built this controller that matches fireballs to the fret buttons on a Guitar Hero controller. There’s quite a lot that goes into this but we think that he hit a home run. The basic components are a manifold with electronically actuated valves, another manifold for the pilot lights, and a modified Guitar Hero controller.
To interface the controller he used an Arduino along with [Bill Porter’s] PS2 library to read signals from the buttons. But the real labor intensive part of the build came with the manifold. There’s a hardware store’s worth of fittings and flexible copper pipe that go into that assembly. In the end this all came together in just one week.
[Jonathan Crawford] is ready and willing to fire things up with his flaming trombone. A couple of years back his band teacher was going through the storage room triaging instruments. This trombone suffered from a bad case of red rot and would never function well again so [Jonathan] was able to get his hands on it and get to work.
He started by sanding down the instrument and painting it with high-temperature spray paint. Flexible copper tubing intended for an ice maker was used to relocate the propane outlet inside the bell of the instrument. A barbecue igniter, controlled with the player’s left thumb, lights the flame.
The torch that [Jonathan] is using would only allow a small amount of gaseous propane to come out the nozzle. He ended up drilling out the aperture, and using a short piece of vinyl tubing to bridge the gap between the nozzle and the supplementary copper tubing. At full blast this allows liquid propane to escape so be warned.
You can see him demonstrating this indoors in the video after the break. He mentioned to us that the first time he tried this out he set off the smoke detector. You’ve got to be careful when playing with fire, whether it’s a musical instrument, or a wearable flamethrower. So, you know, don’t try this at home.
