Fire Pong
For EMF 2016, a small group of us are working on a series of fire effects to be incorporated into an interactive game of some sort (provisionally "pong").
Puffers (a.k.a. "Poofers")
Puffers consist of an "accumulator" tank (usually an empty gas bottle), which is filled from a "feed" tank (a full propane bottle). The supply is regulated to somewhere up to 60 PSI. The accumulator tank is connected to a long "barrel" through a large-bore value which can open and close quickly. This may be a manual ball value or an electronic solenoid value. The accumulator tank is also connected to a pilot flame at the end of the barrel, through a low-pressure regulator.
When the ball/solenoid value is opened, the medium pressure propane in the accumulator tank shoots up the barrel, and is ignited at the end by the pilot flame. This creates a brief "puff" of fire.
Puffers come in many sizes from hand-held to truck-mounted, and can create a puff from a few tens of centimeters tall to anything up to and exceeding 10 meters!

Contributers
Sub-projects
- Bat accelerometer controllers
- basically a Wii-mote
- Should have battery capable to lasting a 3 hour "show", and be recharagle / have batteries replaced overnight for next show. Longer battery life is better
- Communicate wirelessly with control box
- Be good if they could pre-process use and send simply a packet with speed, angle and such, rather than have the control box interpertting accelerometer readings directly
- Should be physically robust & splash / dew proof
- Control box
- Controls puffers via relays
- Controls electro-igniters via relays
- Keeps game state
- Updates display unit with game state
- Accepts input from bats (wireless)
- Can be placed in non-game mode(s), e.g. test mode, demo mode, use up all the gas mode etc.
- Should be splash / dew proof
- Display unit
- Possibly using Matt Little's green segment display, or station scrolling text displays
- Should be splash / dew proof
- Pilot lights
- For big puffers
- Frame / stand for row of small puffers
- Elevate puffers from the ground a little
- Secure against gusts of wind
- Will having wiring routed over it
- Game testing
