In our hands-on review of the Digilent chipKIT Uno32, we posed the question of what the lasting appeal might be for a 32-bit Arduino work-alike. We felt it needed some novel applications exploiting its special features…not just the same old Arduino sketches with MOAR BITS. After the fractal demo, we’ve hit upon something unique and fun…

It’s that time again, time to take on the machine with the Hackerspace, Crash Space (and part two)! The team of Californians set out and successfully turned the front of their building into a musical instrument, similar to [David Byrne’s] Playing the Building. When a pedestrian walks by they set off distance sensors, which in turn actuate mallets that strike particular objects to produce a tone. We were pleasantly surprised at how interactive the installation was, even if it didn’t sound that great. But will it be enough to beat out the previous two teams? And how will it do up against Artisans Asylum’s not what you’re thinking Breakfast Machine next time?
Because the Arduino is in such high demand for producing multiple musical tones at the same time; [Jeremy Blum] has successfully figured out the math and other necessaries that will take your once previously single tone producing MCU and turn it into a 5 tone producing machine. unsurprisingly its really just some creative use of PWM control but it all works out in the end anyway and helps prevent you from purchasing additional sound generating chips. This truly does open up some new doors, as [Jeremy] shows with his still in production thingamakit like project: ReacXion.
[MicroMinded] took us way back to our childhoods with his experiments and subsequent YMstream music player based on the Yamaha YM2149 sound generator used in old arcade systems, computers, and even phones (think chiptune). This reminds us of the Chipophone, only this time the sound is achieved from ICs used back in the day, rather than MCU waveforms.
There is still some work to be done to make the music player have a bit more functionality, but for now source is available if you want to make your own. Of course you might come across a small problem; finding an SSG is a tad bit more difficult than say, an Arduino. If a good resource is found, please share it in the comments!

While we could be content following our “kiddie d-day” as [Caleb Kraft] suggested. We know you can’t continue such an awesome Friday without trying to blow yourself up first.
This Wiimote Rubens’ tube caught our eye. A PVC Aluminum irrigation pipe is drilled with holes and propane is pumped through. A speaker on one end creates changes in pressure and a neat light show follows suit. [ScaryBunnyMan] went further though, with a collection of software and a Wii Remote he “plays god” controlling the music, and thus, the fire. Check out a fun video after the split.

This is (video above) perhaps the most abstract way of playing sounds…ever. Yes, we’ve heard Hard Drive music and Obsolete technology bands, but [DJ Sures] brings us the first ever, spark plug instrument.
Much like Velcro and Teflon, the musical spark plug is claimed to be an accident. After testing energy use vs. spark power with his flare stack ignition controller, [DJ Sures] noticed that different frequencies could be produced. It was only a matter of reprogramming before death metal Twinkle Twinkle Little Star is heard. Now he just needs to refine it a bit and build a full stereo cabinet.
Finally a guitar that all of the arcade gaming geeks can jam with. [Mike Davenport] sent us his 8bit arcade based guitar for his senior project. Details are a little sparse if you intend to build you own at the moment, but he does mention the basics: such as it uses an FPGA for logic and function, the strings and joystick modify pitch, it has selectable waves and other parameters, and even includes save banks! Check out a video of him playing street fighter rocking out after the break. Continue reading “Part arcade, part guitar”
