[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.
[Yoshi Akai] built a sequencer that is part steampunk, part injection molded plastic. The LEGO sequencer MR II has eight steps in a loop that is manipulated by adding the colorful blocks to a green base plate. Each color corresponds to one particular sound which can be modified by building skyward. On the other side of things he’s added a beautifully crafted control area for knobs and switches. We didn’t see much info about what is inside the device so, watch the clip after the break and then feel free to start the speculation in the comments.
This is a similar concept to the coin sequencer. From the picture above it seems the blocks have been altered and perhaps use light to identify the different blocks.
The Squeezbox media streaming systems are compact Linux WiFi enabled radios that let you stream your collection anywhere,so long as you have an AC or USB outlet nearby. But [Achim Sack] wanted to stream his collection from anywhere with no wires attached (translation). Some poking and prodding revealed a connector actually designed for a battery and serial, but no commercially available battery yet.
The system requires a temperature sensor and if you want serial, a USB converter, but overall a simple process that could be done in an afternoon. Giving your box ~10 hour of life and even fits inside of a back compartment.

[Moritz Wolpert] built this gem of Victorian hardware by hand. It is a sequencer and features beautiful detail work as shown in its MySpace gallery. Other than that we don’t know a lot about it. You can also take a look at [Moritz’s] main page, but prepare to be annoyed by the hideous web-styling that really undercuts the beauty of his physical product.

We always wondered what happens to ancient pianos when the internals can no longer be kept in a playable condition. [Jean Philippe Roch] gutted his elderly upright and fit a Korg Triton inside. After the break you can watch a few videos including a slide show of the work log. [Jean] separates the Korg keyboard from its case and places it in the empty upright piano rank. He then mounts the Korg’s controls in the front panel and adds motorized control to reveal this hidden secret. The project is finished with speakers in the bottom portion of the upright and blue LED lighting effects.
The result is a pretty nice show-piece. It’s not as hacky as vocoding, but we really love the finished look.
This guitar pedal can record, playback, and modify samples. [Colin Merkel], also know for his work on electronic door locks, built this to replicate some guitar effects he heard in recordings. By tapping the button at the bottom with your foot the device begins recording. Another tap stops the recording and starts the loop. That’s where the rest of the controls take over, with settings to adjust the speed of playback, volume, and the type of playback looping. The video after the break gives a great demonstration of these features.
[Colin] built this around a PIC 18F877A with a 256k RAM chip to store the sample. There’s a bunch of other components that go into this and we’re dumbfounded that he built it on protoboard. This would be a multi-breadboard prototype for us and we wouldn’t think twice about laying out and etching our own PCB. He admits that the point-to-point soldering stretched his skills to the limit but he doesn’t say how many hours it took to get the circuit up and running. This is a great addition to the cool guitar pedals we’ve seen here.
Buy stock in hot glue, this project corners the market on the stuff. [Leafcutter John] uses the hot goop as his water-proofer of choice when building an underwater microphone (also known as a hydrophone). By installing a couple of piezo elements on one lid of a tin can he is able to record some amazingly clear audio. This is aided by a pre-amp inside the metal enclosure. By cleaning off the clear coating from the inside of these steel can parts, he was able to solder the seams to keep the water out. In the end, coins are added for ballast and any remaining space is completely filled with hot glue.
He’s got a handful of example recordings on his project page. Here’s an what a running faucet sounds like from under water:
