Fire Breathing Animatronic Waterfowl, Just Because

Unless you’re a collector or a hunter, waterfowl decoys are pretty boring. Radio controlled decoys that can putt around are kind of cool. But a radio controlled animatronic fire-breathing decoy? That’s the very opposite of boring.

This is another one of those projects from the “Why the Hell Not?” files, and [David Windestål] is pretty clear that there’s no practical purpose for a flame-throwing, floating fowl. This doesn’t stop him from including 100-plus pictures as well as the video below in his detailed build log, and there are actually some tips to be had here. The remains of an RC racing boat that can hit 30 km/h are used for the floating gear; sadly the decoy superstructure reduces the speed by a factor of 10, so if you’re hoping for a high-performance decoy you’ll be disappointed. The rotating head and evil glowing LED eyes make up for that, though, as does the articulated beak. But the butane flame thrower, with laser-cut acrylic frame and servo flow control, really adds to the menace of the Duck from Hell. Or goose. Whatever.

As with most projects of this type, this is clearly a “do not try this at home” build, but it looks like a bunch of fun. For more ill-advised fun check out this mini RC flame thrower or the Doof warrior ukulele.

RC Mini Flame Thrower Brings the Burn

It goes without saying that a radio controlled mini flame thrower can be nothing but a bad idea and you should never, ever build one. But once you watch the video below, you’ll be tempted to try. But don’t do it – you’ve been warned.

That said, the video below shows that [Make-log]’s remarkably compact build is chock full of safety interlocks and sports a thoughtful and informative user interface. It’s fueled by a small can of spray deodorant whose valve is actuated by a servo and ignited by a spark-gap igniter. Alas, this final critical component is no longer available from SparkFun, so if you choose to roll your own – which you shouldn’t – you’ll need to find a substitute.

We’ve featured an unreasonable number of flame thrower projects before, including a ton of wristmounted units. Of course if you’re a musically inclined pyromaniac, you’ll also want to check out this mini Doof Warrior setup too.

Wrist-mounted flamethrower on the cheap

flamethrowerGlove

Everyone wants to be Iron Man these days, but without a spare arc reactor lying around, you’ll have to settle on building a backup suit component. [Xavier] documents his take on the wrist-mounted flamethrower in this dirt-cheap and unquestionably dangerous build. Cobbled together from parts found at a local hardware store, this glove has the typical “ready” setting with a small flame that, upon turning one’s wrist, erupts into a loud and large swath of flames. We suspect the mask worn in the video below doubles as identity protection and to prevent accidental hair conflagrations. Skip to the end for a demonstration.

Though not the first flamethrower build at Hackaday, [Xavier’s] is the only one with a guide and is certainly the cheapest. Be sure to look into the second generation of the Prometheus flame thrower and its subsequent third version that we featured a couple of years back. Not everyone’s flamethrower is wrist-mounted; some people put them inside a trombone. Remember, don’t try this at home.

76 flaming trombones led the big parade

[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.

Improved arm mounted flame thrower

prometheus-flame-thrower[Everett] is at it again with Prometheus, an arm mounted flame thrower.This is the third generation of the project and makes some huge advances over the second generation we saw last year. We’d say he’s reached cinema/stage-performance quality with his design.

The self-contained system is completely arm mounted with a fuel reservoir mounting behind the elbow. The new version adds an adjustable flow valve actuated by a servo motor to regulate the flame size. An arc generator has been incorporated to replace the lighter from the last version. A microcontroller measures wrist angle and takes care of creating the arc and regulating the fuel supply.

Prometheus is small, controllable, and frightening. See a full demonstration as well as some video of the prototyping process after the break. Does this make you wonder how much burn cream [Evertt’s] needed over the years?
