Initially I wanted to include all the instruments in the Ruben’s tubes, so I started figuring out the notes which would be used and which tube they corresponded to for the piano and bass. What I didn’t think about was the use of multiple notes in the tubes at one time. Because of this, I… Continue reading Composing to a resonant frequency set
This was our initial pressure test. We later followed this up with a soapy water test to ensure no leaks were present in the system.
In the early prototypes, we were using a 2mm distance between holes, at a 1.5mm hole size. We wanted to figure out the best distance/hole size for allowing the flames to run all the way along the tube without have to manually push the flames across with the lighter (which is what was being done… Continue reading Determining best flame hole distance
Cutting the tubes down to size: Creating the gas input end pieces: Setting up prototype stand system Testing the speaker routing system: Mocking up outer stand dimensions: LPG certified connections added Stand development Packed up, ready for transport
In this test, it was determined that the tests in video 2 produced the best results. Having the speaker hard against the diaphragm disrupted the sound signal – while still producing results, the standing wave was not as distinct. The third video test produced good standing waves, however the difference in the flame heights weren’t… Continue reading Ruben’s Tube Mockup – Speaker Tests
In this light up trial, we tested the lighting of all 4 tubes, the flame off pit, and piezo ignition for the flame off pit. Unfortunately the piezo ignition proved unsuccessful. We also found that slight wind has a large impact on the flames, thus the need for a more enclosed stand rather than just… Continue reading Ruben’s Tube Mockup – Lighting Up
Determining how hot the Ruben’s Tube burns, in order to best design the entire contraption. Explanation of what we are checking and how. 2. Checking the temperature of the Ruben’s Tube after 5 minutes burning time 3. Checking the temperature of Ruben’s Tubes with a probe 4. Checking the temperature of the prototype stand 5.
