Fire Pong Meeting 2016-01-23

At the space:

Tomandahalf made us a quick release fitting for the air compressor
Ian and russell helped weld it to some 22mm copper pipe
Pressure test with up to 6 bar air at the space, using soapy water to find leaky joints. A few very slow leaks at pressure, but nothing to worry about. Matt Lloyd is good with a spanner so we pretty much eliminated them.
Toby made the funnel / fan dryer ducta lot of pressure
Mouse soldered up power for the dryer

To Leslie Road:

Test up to about 1.8 bar propane, with no accumulator; which turned out to be plenty for an impressive puff with 22mm piping
Regulator has a feature where you press down on the adjuster to get 1 bar out - makes a nice little puff when the non-boost position is low as there is not much storage space in the tubing for gas
No problems with flash down into the pipe
Forgot to weigh propane tank before and after, so we don't know how much we used
Chilli and spuds, yum!

Ian to get parts together for a 15mm prototype using a solenoid valve / no accumulator
Mouse to continue trying to get valve out of empty butane tank for accumulator (Tomandahalf if working on making a tool to help with this)
Perhaps we can have a single 15mm line with several smaller solenoid valves along the length. If they're cheap enough to get 10-15, we could maybe do the original plan of having a fire "puck" for pong! Electric igniters would be good here, or electric + oxygenated (blue) pilots?
Fit gauze into 22mm barrel (although frankly, doesn't seem necessary

Next Meeting: end of next week?
