Coyote-1 Guitar Pedal Available Now

August 26, 2008 by 3 Comments


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.

Homemade Tube Screamer Clone

August 13, 2008 by 5 Comments


[jonboytang] documented his construction of a clone of the famous Tube Screamer overdrive pedal from a set of plans found at tonepad. The tonepad site says you can use the plans to build either a TS-9 or a TS-808, both of which have been classic staples in every guitar player’s setup since the 70s. Although the old parts are no longer available, these new variants still have a really nice sound.

This project is really just a look into [jonboytang]’s etching and enclosure building process, but it may be useful for someone. The build and the circuit look really simple so this would be a great project for guitar players looking to learn how to etch their own PCBs. If you need more information on etching, we would suggest starting out by reading our How-To on etching single sided PCBs. If you are lazy and would rather spend a little money, check out tonepad’s online store. They have a board for this project and many others.

DeepNote Guitar Hero Bot

July 14, 2008 by 18 Comments


A team of five high school seniors have released some videos of their new Guitar Hero bot named DeepNote. This bot uses a group of custom photodiode modules with an 8 nanosecond latency placed on the screen to sense the notes. The Parallax Propeller system takes this input and controls solid state relays hooked into the guitar’s circuitry. After we looked at a few videos of the early prototype system, we could really see how it has evolved. They have custom PCBs and a really nice frame for the photodiode sensors. You can find more info on their How It Works page and view a demo video embedded below.

Make Your Own Guitar Pedal With Beavis Board

June 18, 2008 by 12 Comments

Beavis Audio has recently released the Beavis Board, a kit to help fledgling guitar pedal builders. The kit addresses four typical problems in this endeavor: learning to solder, dealing with breadboards, sourcing parts, and making sense of schematics. By including a breadboard/psu/switch combo and tons of other parts as well as informative and easy to read schematics, all of these problems are alleviated, allowing eager builders to get to work right out of the box.

The kit costs $249 and we’re guessing it’s a little too “entry level” for most of you. It has a highly informative manual in PDF format. You could use that to get ideas and then source your own parts. Have any of you built a guitar pedal specifically for prototyping?

Guitar Hero Actuator

June 11, 2008 by 5 Comments


Another day, another EE that refuses to play Guitar Hero properly. [Julian Bleecker] went into the design of this Guitar Hero actuator not really knowing how to size solenoids properly. Luckily, trial and error can get you a long way. The first solenoids he purchased couldn’t apply enough force. The second was overkill. It was certainly strong enough but too heavy and too large to mount to the neck. The final set ended up being both the right size and working well even at 12V, half the design voltage. The elegant mounting system is what really makes this project shine. [Julian] provides the schematic for the ATmega168 driver board, which is an Arduino stripped of the extraneous bits.

In-cable Guitar Preamp

March 29, 2008 by 25 Comments


[Bryan] sent in this old but excellent guitar cable hack. [J. Donald Tillman] managed to fit a fet based pre-amp inside the 1/4″ connector of a guitar cable. It’s phantom powered – so it’ll leach power from the sound board/mixer. I’m just impressed that he fit the thing inside there.

On a side note, This is the kind of crap that gives hackers a bad name. I hope the jerks behind it end up as Soylent Green.
