FLAMES IN YO FACE 5000 + 1
built with an arduino, some copper pipe, a solenoid and a couple of relays! and runs off lighter fluid!
i took influence from this project :-

which i initially tried for the flamethrowing organ, but that quickly got big! but this one is nice and portable. however it only holds enough gas for 10/15 seconds of solid flames. but thats more than enough for a song of it firing off for a second here and there.....
its basically a big posh lighter..you know when you fiddle with the lighter to make it make big flames.
when i was making it.... i somehow stupidly looked down the refuel nozzle and undid the tap and freezing cold pressurised lighter fluid went right at my eye.. I needed to get it looked it, it hurt like a B$%&*%£
