A Rubens Tube is a pretty flashy piece of physics demo gear that uses fire to show the acoustic standing wave pattern inside an organ-pipe like tube fitted with a loudspeaker at one end. The 48” long, 2.5” diameter tube is filled with propane, which escapes through a series of 50 0.043” diameter holes spaced by 0.9 inches all along the length of the tube. When sound is played though the speaker at one end of the tube, the flame height is modulated by the acoustic pressure from the speaker. When a single tone (sine wave) at a resonance frequency of the system is played though the speaker, the heights of the flames map out the sinusoidal shape along the length of the tube.

A Hackerspace or Makerspace in many cases act as a co-op community workshop that operates so that members may have access to tools and manpower to complete their own personal project which would have been impossible on their own due to either lack of tools, manpower, or expertise. One aspect of our hackerspace / makerspace that we would like to emphasize both in recognition and in activity is that we are a nonprofit entity in DFW.Visit our site www.dfwmakersclub.org/ for more information on Makerspace
I’ve recently made a Cacophonator, whose circuit description and board layout are easy to find on the web. I etched the circuit boards at the Milwaukee Makerspace, after modified the board layout, drawn in DipTrace, so I could add SIP sockets and pin headers to tidy up the inside of the project box. The sockets also allow the board to be easily removed, despite the 20 wires running between the board and other components inside the project box. This all makes for an extremely tidy project box interior!

We actually have a box of 3D glasses at the Milwaukee Makerspace (the old fashioned red/blue cardboard ones) so I thought I should try to make a 3D egg.
