[kernelcode] has built this pretty slick looking sequencer/groovebox and shared the process with the world. At its heart you’ll find an AVR atmega168 along with a hand full of buttons and blue LEDs. He says the total cost was somewhere around £15-20, so that’s somewhere under $40 for the American readers. There are tons of great pics of the build and it looks like he’ll be uploading source code soon as well.

The magnetic tape found in audio cassettes can be fun to play with. This installation, called Signal to Noise, relocates the heads from cassette players to the tips of your fingers in the form of a glove. An accompanying wall has vertical strips of tape which you run your fingertips along in order to play back the stored audio. Get the speed right and you can make out what’s on the tapes. Move back and forth and you’ll be scratching like the worst of DJs.
If this were teamed up with a Melloman it would make for quite a performance. See and hear this curious device after the break.
[Vsergeev] built an echo pedal for a guitar or with other audio manipulation applications. He used an mbed microcontroller for the project. You may remember Hackaday writer [Phil] labeling the mbed an ‘Arduino on steroids’, and it certainly handles this audio processing quite well. We’ve included a clip of the echo effect after the break. During the design process, [Vsergeev] used LTspice to simulate the analog circuitry and make things right before committing to the physical circuits.
Some of you may remember when we introduced you to [Kyle’s] Electronically Modified Didgeridoo. Those same members will have their hearts warmed knowing he’s still playing and advancing on his Didgeridoo, now including real time video processing. There isn’t too many details aside from it being controlled by an ATMega168 and an unknown analog switching chip, and in its infancy it just looks like a bunch of dancing white lines but we expect this to turn into one amazing display.
Oh, and those determined on making their own Electronically Modified Didgeridoo should keep an eye out for the April ’10 issue of Popular Science where the instrument will be featured.
[Adam] wanted a stereo that could stand up to rain and keep sand out. He ended up building this beach stereo out of a cooler. The cooler’s already made to be water tight. He cut holes in the front and back for marine speakers and added a water-tight bezel and cover for the controls on the deck. Inside you’ll find a marine battery to power the unit. Now he and his friends can rock-out even in poor weather thanks to this portable and rugged unit.

[Aaron] calls this project “Stochasticity”. It uses two sponges as a musical interface. The performer wears a wrist strap and then draws on the table with water from the sponge to play different notes. You really need to watch the video to fully understand what’s going on here.
We’re guessing that this is Arduino based since some of his other projects are as well. You can try out another quick project of his, an Arduino electromagnetic field detector. Check out video of that after the break.

[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.
