Reader [Kelly Regan] flies large scale RC planes, but would often need someone call out flight sequences while rehearsing. Not wanting to impose on fellow club members, [Kelly] built a sequencer caller from a cheap MP3 player. It just required extending the FWD key to a pin header. Those pins are connected to a custom switch on the back of the controller. Each maneuver is recorded with 30 seconds of padding and then added to a playlist. Once the maneuver is complete, a quick press of the button moves on to the next track. It’s always nice to see people building devices that the consumer electronics industry probably wouldn’t.

Coyote-1 Guitar Pedal Available Now

OpenStomp’s Coyote-1 is now available for $349. The guitar effects pedal lets users design and upload their own effects to the device. It has two stomp switches with LEDs, an LCD display, and four user assignable knobs. The back has 1/4″ in/out and one selectable 1/4″. It also features NTSC composite out, a headphone jack, mini-USB for uploading, and an RJ11 I2C bus for expansion. The processor is a Parallax Propeller Chip. While the OS on the pedal is open source, the hardware design and effect design software are not. You can check out the source and product manual on their forum. If you’re more interested in breadboarding hardware, you might like the Beavis Board we covered earlier.

Furbies Transformed Into A Furby Gurdy
[David Crammer] must really like nightmares. The hurdy gurdy is a stringed musical instrument, dating as far back as the eleventh century A.D., where the strings are sounded via a rosined wheel that is turned with a crank. [Crammer] took this unique instrument, applied his circuit-bending and Furby-scalping skills to generate a Furby Gurdy that sound like Kraftwerk on acid.

SyncMaster, Home Made Modular Midi Controller.

[D.St-Amand] is designing the SyncMaster, a compact modular midi controller, from scratch. The design focuses on a modular build where you can swap out pieces like the one pictured above to achieve different layouts. Not only is it modular, but its very compact. Shown next to some common competitors, it looks very sleek.
Development seems to be moving forward, the pictures have been updated frequently. Lets hope to see a fully functional demo some time soon. Some more detailed information on the build might be nice as well. This may remind you of our story on MachineCollective. While there are similarities in that they’re modular, SyncMaster appears to be a much more polished and portable product. Keep us updated [D.St-Amand].
How-To: Hack A ThingamaKIT

The ThingamaKIT is an anthropomorphic analog synthesizer kit from Bleep Labs. Using “LEDacles”, photoresistors, knobs, and switches, it generates interesting high pitched vocalizations. Bleep Labs sent us a review unit and this article shares our experiences building and using the kit. We’ve also included a tutorial on making some hacks, modifications, and circuit bends to it. Skip to the end to see a video of our hacked kit in action.
Blip Festival: Reformat The Planet

Pitchfork.tv is showing the documentary Blip Festival: Reformat the Planet for one week only. The Blip Festival is an annual chiptune event in New York City featuring musicians who use video game consoles as part of their production. The documentary has a ton of artist interviews and music from all across the spectrum. Most of the initial featured artists are using the Game Boy LSDJ tracker cartridge. [Nullsleep] has put together a tutorial for the device. You’ll see a lot of other old hardware and hear discussions of coveted mods like adding backlights as well. [Mark Denardo] is shown using a PSP as part of his performance. Other people are using software like Fruity Loops to build tracks with Nintendo samples. Honestly, our favorite part was a clip of the loud objects doing a live soldering circuit bending performance on top of an overhead projector at the Bent Festival. Although not musical, Element Labs’ Versa TILE makes a fairly mesmerizing backdrop throughout the film too. You can find links to all the featured artists on last year’s festival page.
Blip Festival 2008 happens December 4-6 in Brooklyn, NY.

RGB Monome Clone

[Julien Bayle] has posted this great breakdown of building an RGB monome clone. He is a musical performer using Ableton Live. He wanted to do away with the need for a computer screen and found that the monome would have been perfect had it been RGB. So he decided to build his own.
The parts list for the entire project is as follows:
- 1x Arduino board
- 4x Sparkfun breakout PCB
- 4x Sparkfun buttons pads (like our door lock)
- 4x Sparkfun buttons bezel
- 64x RGB LEDs common cathode
- 64x Diodes Small Signal (1N4148)
- 1x MAX7221 (LED Driver)
- 1x 74HC164 (8-Bit Serial-In, Parallel-Out Shift Register)
- 1x 74HC165 (8-Bit Parallel-In, Serial-Out Shift Register)
He also has files for the schematics and source code as well as information on how to assemble and test it.
The RGB aspect is still under development. He is using the LEDMatrix-Serial Interface-RGB from Sparkfun Electronics to run it. It is expensive, but is exactly what he was looking for.
There aren’t very many pictures of the project, and none of the working RGB unit. He makes up for it in sheer information. Many parts have links to manufacturers or support forums. Hopefully he’ll post some pictures and video of the final product soon.
