JoshTheEngineer | Rubens' Tube: Playing with Fire @JoshTheEngineer | Uploaded December 2016 | Updated October 2024, 7 hours ago.
Fire! Watch my newly constructed Ruben's Tube in action with Camilo James' cover of Chet Atkins' Happy Again (see link below). I've only been playing around with this for a couple days now, so I'm still trying to get the best settings figured out.

I'll be making a How-To video in the near future so you can build this yourself!

Here are a couple notes:

1) When I shot this video, there was a draft in the room which is why you see the flames dance around a little bit. When the fan in the room is not on, the flames are all the same height and completely stationary. I don't have control over the fan.

2) In some Ruben's Tube videos, you'll see gigantic flames, which might look cool, but I like the smaller flames which I find to have less hysteresis (of the flame height variation) after coming down from a crescendo.

3) This video turned out brighter than I would have liked, and I have videos where I've used an ND filter and it looks pretty cool. I'll be posting some of those videos in the future.

4) I find that it's easier to see the waveforms if the video is smaller, so if you're having trouble seeing them, don't put the video in fullscreen, and sort of look past the flames, if you know what I mean.

5) One of the reasons the amplitude of the waveforms is small is because I'm using a low volume Bluetooth speaker. I'm looking into getting a better speaker for future videos.

Thanks for reading all that; you're a champ!
