The Amazing Circuit Bending Worm

Following a gruelling audition process, one solo worm was hand selected to perform its own music, without proviso, upon a specially adapted and destabilised FM synthesis circuit disembowelled from a Yamaha PSS-470. For one day, this worm was treated like royalty; whisked around London’s swankiest mud spas and hermaphrodite clubs, before spending an evening at the very best hotel (whatever it’s called, I dunno). Ah, what a star…

Ninbento is a modification of the classic Nintendo Entertainment System that acts as a music visualization system. Using a custom-built circuit and a practice known as “circuit bending,” the modified NES will “listen” to music and generate chaotic and colorful displays to the beat.

Build Your Own Alien Instruments

Build Your Own Alien Instruments

“We send probes into deep space to listen to alien worlds. But alien world’s aren’t always that far away.” – Reed Ghazala

I recently finished reading Circuit-Bending: Build Your Own Alien Instruments. This is probably the easiest, and quickest way to get you up to speed in the field of Circuit-Bending. Reed Ghazala, the internationally recognized “Father of Circuit-Bending,” provides a concise compendium of most issues that will arise during your alien spelunking adventures.

Is this book for you?

Depends. For myself, the book was absolutely worth it. My background is mostly digital. The text introduced me to very rudimentary skills required to build these instruments. Skills such as: soldering, quasi-electronics, drilling, painting, etc… If you can already do these things, even on a basic level, you might not get much from these chapters.

Where this book truly excels is Ghazala’s personal insight and experience. His writing is candid, humorous at times, and allows the reader to get a glimpse of how his thought process works. In many ways, this book is more than just a DIY guide. It is also about composing through the process of electronic experimentation.

In other words, good stuff.

My First Victim

The scene of the crime

I bent my first circuit this Saturday, with limited success.

The victim was a cheap-o $5 keyboard from walmart. Opening it up was as easy as removing the screws. What I found inside was very little in terms of electronic components. There were two long narrow boards that acted as the controllers for the buttons and keys. And then there was this tiny little square where all the “stuff” happened.

Connecting the limited set of dots I had to work with, I found three distinct circuit bending functions: The sound stopped, a popping sound came out of the speaker (which is bad), and the rate at which the samples played back increased by ten-fold. So I soldered a toggle to the only pair of interesting dots on the board. The end. Being useless, I’ll go back and reclaim my toggle.

What did I learn? Uninteresting toys can make for uninteresting bent instruments. Newer toys are probably much more efficient in design, thus having fewer circuits to bend. Don’t touch the hot part of a soldering iron.

Hands on with a Soldering Iron


My first solder

Earlier this week, I stopped by my local Radio Shack and picked up a soldering iron, wire, and a stripper. Yesterday, I finally had a chance to use it when I pulled out an old PC modem card (for practice) and went to town.

I managed to solder six wire ends to random spots on the board. The reason I didn’t do more is because the room I was in clearly wasn’t ventilated properly (got a little dizzy.) The first thing I learned was that the gauge of wire I’m using is a little too thick, though still workable. Second thing was that it was easier to put some solder on the tip of the wire first, then place the tip on the spot I wanted it connected to, and then heat the wire, causing the solder to precisely melt into place. In the end, all my wires were attached well enough that I could lift the board. And none of my solder leaked into an adjacent point of electronic interest.

This weekend, I plan on setting up a space in the garage, so that I don’t have to kill as many brain cells next time. And so that I can finally take apart a toy instrument and play connect-the-dots.
