So, long ago I had read about propane fire poofers. They're pretty cool... I mean, who doesn't love fire?! But, no matter how awesome, they could get pretty boring after a while of seeing the same large fireball. I never built one because I wanted something that would be exciting and thrilling every time I fired it up. So, I put the project on hold until I could come up with an awesome idea.
Back in December 2010, I was daydreaming in class about who knows what, when I thought of my fire poofer project. I thought back to this project
I had read about a while back on Mikey Sklar's website where he uses an ultrasonic sensor mounted underneath a trampoline to shoot off a fireball every time someone jumps. This is pretty sweet, but it has the potential to get pretty repetitive. After a few hundred jumps, I would imagine I would get tired of seeing the same small fireball and crave something more. (besides, I don't own a trampoline!) I tried to think of ways I could apply a fireball shooter to things in ways that would be pretty awesome. I thought of using a microcontroller to sync the fire to the beat of music - now that would be pretty cool, and the patterns would always be different, so it wouldn't get as boring as fast. Then I thought of the game Guitar Hero, which uses five frets, and I had my idea! Simply interface a Guitar Hero controller to a microcontroller that would power some relays which would in turn fire off solenoid valves on five individual fire poofers! Now this could be cool; a large fire "sculpture" that is playable by anybody. Read on to see how I turned this idea into reality in a week's time!
I figure this is as good a place as any to place a disclaimer about my project. FireHero uses controlled blasts of propane gas to create pyrotechnic flame effects. DO NOT EVEN THINK OF ATTEMPTING THIS PROJECT UNLESS YOU ARE FULLY QUALIFIED AND FEEL COMFORTABLE WORKING WITH EXPLOSIVE GASSES, HIGH PRESSURES, ELECTRICITY, AND OTHER THINGS THAT CAN KILL YOU
IF YOU DO NOT KNOW WHAT YOU ARE DOING.
