Pure oxygen? I never did play around with that, but I did make an arduino-powered fuel meter which would inject precisely the right amount of propane. That was a big improvement from "spray and pray", even though I did get quite good at it with butane.

I modified a pen torch to work with a valve stem and mounted one of those to the chamber. Of course, I only used the oxygen cylinder of the torch.

I like your solution. Can you post a picture?
