A friend came across a project known as a Flame Speaker. Â The similarities to a Rubens Tube resonated with me and I was immediately intrigued. Â Some of the best information we could find about it where documented in a 1960s Popular Electronics magazine. Â Apparently hobbyists were making these things in their basements around the country, but for some reason the popularity waned and we were having trouble finding many modern implementations. Â I suppose it’s just a parlor trick anyway.
Well, we did a little brainstorming and came across a fun art project for the magical process. Â But first we needed to hit the lab and see if we can make something actually work. Â After a few iterations of testing, we arrived at this version:
Don’t worry, I’ll have more information about what our setup looked like before too long.
Hi – thanks for sharing these experiments, I’m just looking at doing this experiment. I found a few of the old articles on it, and am sourcing transformers etc. Do you have any tips on what transformer or the power source to use?
do you need the oxy-acetylene torch to get the right type of flame? I’m thinking of using a Bunsen-type burner like plumbers would use for soldering, so im not sure if its about heat of flame height – or the mix of gasses.
I notice that interesting resistor panel, what is that for?
What happened with this project form this point? thanks, T
