Automated electronic ignition

Successful test of automated electronic ignition:
This is the "demo" reel: it's just programmed to go back and forth, with the gas valve turning on and off as needed.

The gas tank shouldn't have been that close to the flame.  Don't do that.

Electronics are still in prototype, as in, bunches of wires hanging off breadboard.  Next step is to figure out how I'm going to have each individual unit communicate with the master.  Right now, my plan for that is to use an Ethernet-to-SPI bridge such as this one:

The idea here is that wireless is both overkill, and not super reliable at Burning Man, where they blast microwave trans-playa for DPW and Ranger comms, as I found out when I built the "Black Rock City Craigslist" project.  RS232 isn't designed for more than a few feet, and it's point-to-point, and not multipoint.  If you want long-distance (more than 25 feet), reliable, and cheap, ethernet is a great option.  Almost all of the hardware is commodity, off-the-shelf.

Also, I need a website, because I need to start putting together a build team, fundraising, etc etc.  Going to get to work on that soon as well.  Want to start looking for studio space, possibly at Box Shop, which is near my house.
