[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:
What sounds like a sex-toy is actually the reason these musicians haven’t been practicing. Marv is the MIDI actuated robotic vibraphone built by [Tim O’Keefe], [Michael McIntyre], and [Brock Roland]. Every key has a solenoid positioned below it. The beauty here is that other than four small holes used for mounting, the vibraphone hasn’t been altered at all. The solenoids are positioned on the outside edges of the instrument but there’s also a hidden secret. A set of dampers have been installed between the two ranks of keys. These are used to stop dampen ringing keys after the note should have stopped.
These guys have exhibited some beautiful craftsmanship. Check out the videos after the break and if you have the chance, see Marv in person at BarBot 2010. If you do attend that robot extravaganza don’t miss your chance to enjoy a breast-pump actuated cocktail.
This looks like a home entertainment center of yore but something’s not quite right. Where is the turntable used to play the music? It turns out that this Danforth Standard Digitrola is digital and doesn’t rely upon wax for an input. [Jonathan Danforth] built it as a show piece and it exhibits fine craftsmanship. A sound driver uses the brass horn and the acoustical chamber to put out what sounds like a fine quality end product. Hear it playing some Daft Punk in the video after the break. The music comes from an MP3 board inside that has a 50W amplifier and reads the music from an SD card. The only control available to the listener is the brass knob which controls the volume.
“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!
