Ipod GPS

[Benjamin] was working for a GPS company called Nemerix about two years ago and decided to hack together this iPod accessory GPS unit.  He is using an Atmel ATmega324 and a Nemerix GPS unit, though he says the GPS unit shouldn’t matter. He is taking advantage of the AiR mode on the iPod which allows a 4 color image to be sent to the screen. There was little information on how to utilize this, but BMW and Alpine had made some car audio that featured this. [Benjamin] picked up an Alpine with this function and sniffed the data stream to get what he needed. He says there is good documentation out there now though.

He says that the source code is available if you ask.

[Jeri ellsworth] of fatmanandcircuitgirl.com has made an audio recorder out of a floppy disk and an old tape recorder. She’s able to record 15 seconds of audio directly to floppy disk. In the video after the break, she explains how it works, and why you hear the creepy reverb effect. The next step is to run this as a pedal effect for stage music, and she even mentions doing a larger hard drive version with the ability to seek tracks.

Condenser Microphone Building

Browsing around today, this project caught our eye. Mainly due to the visual similarity to, well, personal massagers. As it turns out, it’s a home made studio condenser microphone. We would generally prefer to link directly to his personal page, that has a slightly more in dept write up, but it has popups and pop unders, so enter at your own risk.  Generally condenser mics require phantom power to make the magic happen, but he has included a circuit to run them off of 9v batteries. We’ve done condenser mics before, but this seems a bit quicker and dirtier.

Felix’s Machines

Ok, we know you’re going to get mad, there’s virtually no information on the technical side. But the music was so pleasant, and that’s rare.  There’s an interview with Felix, the creator, where he discusses his goals and ideas behind the project. We prefer just to sit and watch though. If you want to make something similar, there were some technical details on a mechanical drum recently.

Bohemian Rhapsody On Old Hardware

Here’s another junk music performance to add to the list. [bd594] put together this rendition of Queen’s Bohemian Rhapsody on assorted computing equipment. The lead piano sound is from an Atari 800XL. Lead guitar is a Texas Instruments TI-99/4a. An 8inch floppy plays bass while a HP ScanJet 3C covers the vocals. He had to dub the scanner four times to get all of the vocal parts. He wanted to use four independent scanners but the prices on eBay were forbidding. The use of oscilloscopes to show the wave forms in the video is a nice touch. Check out our post about Radiohead’s Nude for more examples of this.

The Bent festival, which begins tonight in New York City, is a celebration of DIY musical instruments. Artists from all over converge to beep, blip, and strum for your pleasure. With a heavy emphasis on hacking your own instruments, this is definitely something we’re interested in. If you’ve only heard a little bit of circuit bending and didn’t like it, you may want to give it a try anyway. The musical genres are extremely diverse, it’s not all just random noise.
