There are three types of booths at Maker Faire. The first is the strange corporate booth, like Pepsi ‘revolutionizing fluid intake’ or some such nonsense. That one had the longest line of any booth, in case you’re wondering. The second type of booth is the people you would expect to be there – Atmel, TI, and Makerbot all came out in full force.
The third type of booth were a little hard to find. They’re the ‘show and tell’ spirit of Maker Faire, and [Stephen Hawes] was one of the best. Why? Wrist-mounted flamethrower, that’s why.
The flamethrower is fueled with a propane bottle originally meant for a camping stove, with a microcontroller and pot setup taking care of the height of the flame. Buttons underneath [Stephen]’s thumb takes care of the propane flow and
tazer-based ignitor. The wrist measurement sensor can rescale to adjust the height of the flame to how far the wearer can move their wrist.
All in all, a great project for the Faire, although we did feel a little sorry for the NYC fire marshal that was assigned to [Stephen] for the entire faire. As an aside, we’re applauding [Stephen] for not referencing whatever comic book character has fire shooting out of his hand.
[John] says, “I noticed an unfortunate lack of many flamethrower guitars on the web so I filled the need. ” That’s just awesome by us.
This series of guitar-mounted flamethrowers started with a small build, able to shoot a six-foot flame for about 40 seconds. Yes, very theatrical, but not something you’d want to change out after every song. From there the builds progressed to systems with more barrels, more fuel tanks, and a huge system that shoots 18-foot long flames colored with standard pyrotechnic supplies.
It should go without saying that this stuff probably isn’t something you should try at home. That being said, you really have to admire the craftsmanship and tenacity to make a guitar mounted flamethrower. Just don’t bring it to an indoor gig.

Yes, it’s a little late for Halloween, but before you throw out that rotting gourd sitting outside your front door, how about planning for next year’s festivities with a dragon-o-lantern?
The first dragon-o-lantern that made its way into our tip line is a fire breathing dragon jack ‘o lantern built by [Aaron] for a pumpkin carving contest. The idea is simple; just carve a dragon head out of a pumpkin, insert candle, and spray the open flame with a can of Aquanet. Sure, it’s crude, but with a little engineering it could turn out to be a very, very cool build.
For a slightly more complex build, [Chris] built a fire-breathing jack ‘o lantern triggered by anyone saying the words, “trick or treat.” The key part of this build is a Microsoft Kinect, used for its voice recognition capabilities instead of its capacity to form a 3D depth cloud.
The fire portion of [Chris]’ build is controlled by an Arduino triggering a solenoid to dispense a small amount of fuel into the pumpkin shell. [Chris] doesn’t go over the construction of his ‘poofer,’ but any member of your local hackerspace should be able to show you how it’s done.
Videos after the break.

There’s something special about improvised weapons built for the upcoming zombie apocalypse. Whether it’s a Lousiville Decapitron or a shotgun revolver, we’re always fascinated by homemade weapons. Here’s a few that rolled into the tip line over the last few weeks:
You call that a knife?
[Joerg Sprave], a.k.a. that German guy on YouTube that has fun with slingshots, built a spinning steak knife saw thing. Basically, it’s eight steak knives attached to a wheel and driven with an electric drill. It’s not a terribly complex build, but it does give off a zombie apocalypse/first person shooter melee weapon vibe.
Battery cannon, because why not
Why use potatoes when you can use D-cell batteries? [CasterTown] on YouTube put together a small propane-powered spud gun that can put a battery through a car door. This isn’t the first time we’ve seen batteries used as ammo, but it’s still an extremely powerful build.
Oh man the 60s were cool.
Back in the 60s, safety wasn’t a huge concern. Any 10-year-old could walk into a dime store and buy Jarts – a game consisting of kids throwing sharp spikes at each other. Also, magazines had descriptions of how to build a freaking mortar in a backyard. Able to make a 20-foot grouping at 1900 feet, this would probably merit a visit from a SWAT team today. Needless to say, don’t try this at home.
Don’t do this. Please.
Last but not least is [Rocketlab] and [SadisticTheory]’s $15 flamethrower. It’s just a gas tank from a 2-stroke engine, a 12 volt battery and a pump. Common sense requires us to mention this build is very,
very illegal (apparently it is legal)and extremely unsafe. Don’t replicate this build.
Actually, we take that back. You shouldn’t build any of these weapons because they’re very dangerous. Just think of these as a neat thing to look at. Let other people hurt themselves. You may complain about how unsafe these weapons are in the comments.
What’s thirty-seven feet tall, has ninety-one flamethrowers, and is controlled by an Arduino? Why it’s Pyrosphere, an interactive art piece at this year’s Burning Man. It lights up the night along to the music in a way that makes us want to set up a lawn-chair and watch the show. You can see for yourself in the video after the break, but you really should have thrown on the LED fur coat and gone to see it in person.

Artist [Ariel Schlesinger] has managed to replace an air horn‘s compressed air tank with butane fuel. This hack manages to change the pitch of the horn slightly, as well as making one very noisy flamethrower. While not as impressive as other flamethrowers, this would probably take the cake for most achievable. Currently the site containing the how-to is down, but we would have to recommend not doing this at home anyway. Video after the jump.
