This is an interesting take on a music box. [Blair Neal] is using an overhead projector with a roll of transparency to make a synthesized music box. A camera watches the projected image and feeds data to Max/MSP to produce the sounds. Customization merely requires creative image analysis. In this case, different colored pens or different tracks can be assigned to a sound with the speed of the track based on how fast you wind the transparency spool.

[Matt Kemp] remade this super 8 film camera into a synthesizer. Inside you’ll find a light sensor pointed through the lens. This way, zooming, focusing, and pointing the lens elsewhere will change the sound. He also refit the original controls to monkey with the output. Turn your speakers up when you watch this, your co-workers will love you for it.
“Everyone needs a hobby,” they tell us. For the blogger mysteriously identified only as “R,” that hobby would be an almost fanatical nostalgia for the Commodore 64 computer.
At first we thought this was a fan community site, but apparently it’s all the work of a single person. [R] has tweaked, extended, repackaged and resurfaced this 1980’s icon in nearly every imaginable way. They tend to gloss over the technical aspects of these mods, but that’s okay – the C64 is such an exhaustively documented system now that the site dwells mainly on the aesthetics and meaning of these reborn devices.
The 64 has made an indelible impression on electronic music, and the machines are still sought after by collectors, composers and circuit-benders. [R] pays homage by housing these vintage systems in styles reminiscent of even vintage-er synthesizers. Any one of these would warrant a post here, yet there’s a whole collection to browse. Check it out!

This synthesizer relies solely on an FPGA for key detection and sound synthesis. [Chris] and [Joe] built it for their final project at Cornell. The hardware implementation includes velocity sensing for the keys. While at rest, each key contacts a strip of copper foil. A matching strip of foil contacts the key when it is depressed. The velocity data is extrapolated by detecting when a key leaves the rest state and arrives at the depressed state. Sound synthesis is handled in hardware using the Karplus-Strong string synthesis method. If you want to hear what it sounds like, they’ve posted a video (MP4) that shows off the creation. It sounds like an electric piano to us, so mission accomplished.

Subcycles is a sound controller application that [Christian] is using on the third multitouch display that he built. The screen is a sheet of acrylic in an aluminum frame. The image is rear projected onto an area covered with Digiline dispersion film. As with other projects that use the Community Core Vision package, a PS3 eye camera captures the touch information.
This build does a great job of including the audience in what the musician on stage is doing. [Chris] points out that the sight of artists staring at laptops on stage is becoming more and more common. The ‘Minority Report’-like interface that Subcycles uses makes not just for interesting music, but for an added visual reinforcement to the live part of the performance.

We’ve been watching this project ever since [Dann] emailed us about the first prototype back in September. This bassline generator has a lot of functions we like, such as an adjustable melody seed, light-sensitive controls, and device interactivity. Line up a row of them and they’ll sync up the beat, building layers of sound on top of each other (see the first video after the break).
The system is built around an ATtiny84, putting its pulse width modulation channels to work for sound generation. [Dann] has some kits available but he’s also posted everything – the schematics, PCB layout, and code – if you want to throw one together on a breadboard.
It’s not a bazooka, but this altered instrument makes it look like the player is toking off of some type of weapon. [Kyle] wanted to take the already mysterious sounds produced by a didgeridoo then capture and alter them electronically.
The physical build of this project is nothing short of beautiful. He’s mounted several curved control boards to the outside of the instrument. The controls feature six push buttons, five toggle switches, and six potentiometers that interface with an Arduino. The sound is picked up by the device then sent along with the switch settings to a computer via Bluetooth. The computer then works its magic to create the wicked audio effects heard in the video after the break.
His article, linked above, includes several diagrams detailing the synthesis process. They’re a little beyond our understanding but if you know what’s going on, please share your insight in the comments.
