[Noisebridge-discuss] seeking gas plumbing advice for brain-control of flames

[Steve Castellotti]

hey all--

     I'm looking to produce a portable version of live flame effect to 
be controlled via EEG.

     Roughly I'm seeking to feed a bunsen burner from a camping stove, 
with an electronically-controlled valve or solenoid in between. 
Brainwaves are collected and analyzed for levels of concentration and 
focus (beta), and when a certain threshold is reach a microcontroller 
(either Arduino or Raspberry Pi) sends a signal to open the valve or switch.

     Ideally I could have variable control over the flame level, which 
would only require a single valve and gas line. Worst case I would split 
the camping stove into two tubes, one with a physical valve open to the 
minimum level necessary for the pilot, and a solenoid on the other side 
which opens the line fully when triggered.

     Does anyone have experience with this sort of gas plumbing work? 
Any recommended websites for information or purchasing gear? Any advice 
would be appreciated. Handing the brain interface is covered.


     This guy built something along the right lines and photo documented 
his effort, but the text lacks detail. It looks like he has a flame 
element with  only mentions a thermocouple connected to the Arduino, 
which I assume is a heat-sensing safety mechanism:

     ... and here is the large-scale version I hacked onto a Flaming 
Lotus Girls sculpture last year:
