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 wrist–mounted units. Of course if you’re a musically inclined pyromaniac, you’ll also want to check out this mini Doof Warrior setup too.
No spark igniter from Spark Fun? Not fun.
The irony!
And, spray deodorant? So this could be a RC Mini Flaming Axe Thrower.
WD-40 comes in mini spray cans, works better than Axe body spray in my opinion.
Not that I’ve tried, but I believe you. Though I’ll ask if you’ve had any problems with it burning on when the flame is supposed to be extinguished, since WD-40 is heavier and doesn’t evaporate as readily.
The red plastic tubes do tend to continue burning afterwards, and melt.
Electrical Contact Cleaner works well:

I would have used a butane lighter refill, they come in all sizes.
It’s surprisingly easy to blow out the flame, you’d need to make a proper burner for it ;-)
The spark gap igniters are readily available on eBay
Um. I think I’ll pass.
This one appears both more fun and powerful: https://www.youtube.com/watch?v=lmD3rXUR1Tw
I dunno looks like standard hvac heater parts to me.
Otoh flamethrowers tend towards napalm fuels that stick. This looks more like a BBQ burner with a huge leak.
My $0.02 and I’m staying with that.
In 1999 i built a gameboy controlled flame thrower while living in Wrigleyville, chicago.
I wimped out and never fired it off in the city – it worked with compressed kerosene and a propane pilot.
The only interesting thing might be that it worked with a weird cartridge that allowed loading C++ code into a gameboy cartridge, and provided GPIO. Neato.
How does one compress kerosene?
Guessing he means a pressure tank with kerosene and compressed air.
Exactly.
What was that cartridge called? I’m kinda interested in it.
