Project:Fire Pong Meeting 2016-07-14

Since Last Meeting Notes

Lots of stuff has happened since the last meeting was formally documented. Ian and I have been working pretty much every night on the project and much has been achieved:

• Re-worked the spark terminals. The rounded heads on the previous iteration caused the voltage to rise above the breakdown potential for the internal insulation in the sparkers, killing several of them. We re-made them with screws with sharp edges, and having a bundle of wire fibres protruding from the top of the sparker. This still needs sustained testing. Ian also ordered a bunch more sparkers.
• We now have enough 15mm tube for all the small puffers, but we're still waiting for delivery of more 1.4" BSP -> 22mm solder joint adapters
• Small puffer segments now have stabilisation legs
• Mouse purchased ply and made a mounting board for the supply segment. Waiting on delivery of a final gauge, and then the supply segment can be bolted to the board. The board has been painted black and had brightly coloured stencil markings to show which valve does what and the on/off positions of each
• We found an enclosure for the power supply, and Ian has started work on that to make holes for all the buttons, cable glands and such
• Greg Duckworth came through with a tank adapter for one of the large puffers. It works (with a minuscule / nothing to worry about leak). Testing with air from the compressor it is very impressive. Should get to test it this weekend coming.
• Mouse extracted the valve from another butane cylinder - will check if previous valve goes in the hole, and if so, give Greg the go-ahead to make another adapter.

Next Meeting
