Reader [Jimmy] sent us some info about his recently completed antique radio to audio streamer conversion. The electronics from the original radio were too far gone to repair, but he took the time to pull apart modern components to provide a polished looking finished project without losing the antique feel. We like it, but we are just suckers for that old time look. Check out his blog for more photos.

[Robert] wrote a program using Max/MSP that lets him make music with his guitar hero controller. There’s another video after the break where he walks through the various features but here’s the gist of it. This works on Mac and Windows and allows a sort of ‘live play’ or midi mapping mode. In the midi mode each key can be configured to do your bidding. His example uses the pick bar to scroll through different samples and the green button the play them or the red button to stop.
The live mode us much more involved. In the software you choose the type of scale and the key you’d like to play in. This makes up for the controller’s lack of enough frets to make it a chromatic instrument and these settings can be adjust from the controller. There is an up-pick offset that makes the upward movement of the pick bar a different note than the downward movement. The motion control can also be used as an input. He demonstrates pitch bending and cutoff using that method.
This looks like a lot of fun. He needs to team up with [Joran] to add drums to the mix, forming a much more creative rock band than you can buy in the store.

It’s pretty creative to use a 9v battery as an enclosure. That’s what [Osgeld] did when building this amplifier. There are several advantages; they’re easy to find, it keeps a bit of the dead battery out of the landfill, and this method provides a built-in connector for a 9v power source. In this case the circuit is built around a LM386 audio amplifier. It’s glued to the back of a potentiometer and wired up with the other components for a package smaller than a quarter. A stereo jack reside in the side of the battery case with a cable and alligator clips for connection with a speaker. Now the amp can be quickly connect to any 4-8 ohm speaker.
[Pat Metheny] has a robot armada backing him up when he performs on stage. They’re going on tour and he’s done an interview explaining his mechanical band. Like the auto-drummer, this setup uses multitudes of solenoids to play the percussion instruments, each getting commands from a computer. It’s pretty wicked to see him use his guitar as a marimba controller; it’s so responsive that he can tremolo and the solenoid follows in kind.
But there’s a lot more going on here. We love to see crazy facial hair from time-to-time, but this guy’s just got crazy hair! This easy listening isn’t exactly hair-band material but more like live-action Animusic. It’s also reminiscent of the automated orchestras at House on the Rock, an attraction you may remember reading about in American Gods. It’s fun to kid, but whether you like the music or not, he’s certainly talented when it comes to this genre.

This is the multichord, a one-string musical instrument built by [Christopher Mitchell]. The string is a 20 pound mono-filament thread stretched between a wooden bridge and the read/write head of a hard drive. The idea is that the vibrations of the string are picked up and amplified acoustically by the sounding box that serves as the body of the instrument. The frequency of vibration (pitch) is changed by adjusting the tension of the string through the application of various voltages to the HDD head. A relief spring has been added to the head to take the resting tension off of it, making it a lot easier to fine-tune the settings for each note. A keyboard made of twelve buttons selects each different pitch as the string is plucked.
[Christopher] is continuing to post great hacks; we’ve seen a glove input and a giant VU meter from him in the past. Take a look at the multichord in action after the break.
[Benjamin] built a sequencer that uses a turntable and light sensors to lay down a funky beat. If you like creepy videos with repeated gratuitous corderoy-clad rear-ends we’ve got you covered after the break. Art film aside, he’s got an interesting project. Four light sensors are mounted below the turning record with LEDs hovering above. His hatred for old LP records is apparent because holes must be drilled in a disc for the light to shine through. The four notes in the sequence can be altered in voice and color, along with controls for motor speed and direction. The project also has four manual inputs to add some variety to the repetitive beat sequence. It’s a bit less practical than the penny sequencer but fun none-the-less.
The Misa Digital Guitar is a digital music controller like we haven’t seen before. The body, machined out of ABS, looks like a guitar. The player puts theirs hands in the same places you would on a guitar but the lack of strings make it something different.
The left had manipulates inputs in the form of 144 sensors, six in each of the twenty-four fret positions. The right hand doesn’t strum, but uses a multitouch screen to control the inputs. The UI looks solid, something you’ll have to see for yourself after the break. Tieing this all together is an AMD Geode processor running Gentoo Linux. That means this is open source and begging you to make it do your bidding.
