Circuit bending Probing for "bend" using a jeweler's screwdriver and alligator clips Circuit bending is the creative, chance-based customization of the circuits within electronic devices such as low voltage, battery-powered guitar effects, children's toys and digital synthesizers to create new musical or visual instruments and sound generators. Emphasizing spontaneity and randomness, the techniques of circuit bending have been commonly associated with noise music, though many more conventional contemporary musicians and musical groups have been known to experiment with "bent" instruments. Circuit bending usually involves dismantling the machine and adding components such as switches and potentiometers that alter the circuit.

DIY Audio Stuff.url First, I must mention the best DIY pro audio board on the web, "The Lab" . My projects are/have been: Neve 1290 clone RCA BA31A clone My own preamp design Gyraf G1176 osccom.url circuit_bending.definition( ) Term coined by q.r. ghazala to describe modifications made to electronic toys and cheap electronic instruments by connecting various points of their circuits in ways that were not meant to be in order to modify the existing sounds and to create unexpected effects or unpredictable noises. circuit_bending.info( ) This kind of modifications have been made by various people since the early 70’s (and before on less ‘popular’ devices) but have only recently gained popularity, because of articles in papers like ‘experimental musical instruments‘ or on various websites. Circuit bending is in fact just one recent instance of a century-old tradition of messing up technology to create artistic devices. And circuit bending is also a way to (more or less) easily make new (more or less) original electronic musical instruments that don’t cost lots of money, which is always a good thing for most musicians :).
Here's some mp3 sound samples, movies, and pictures of bent instruments and toys Grandma had a noise band back in the 1930s! Legend has it that a young woman hot-rodded a tube radio and put on Vaudeville style noise shows in the mid-west around 1933. Is she still living among us? Read all about it on my ReGurgiTron site...

Interaktion — Institut Visuelle Kommunikation — FHNW HGK Basel Seminar: Data Exploration Spaces Data coins our contemporary culture by sensing, storing, archiving, transferring and computing our lives, behaviours and communication. But data is also known for being volatile, hidden and overwhelmingly confusing. In this seminar we continued our investigations into the narrative potentials of design and data and strived to create data exploration spaces. circuit-bending YOU can circuit-bend. The following discussion will start new benders on the right path. Also see the Anti-Theory Workshop section, the various instrument galleries and the PSF interview with Reed for additional insights into the process. If you learn to solder and can drill a small hole to mount a switch in, you can circuit-bend.

The 4017 IC is CMOS, and therefore sensitive to static electricity! Any single-pole, single-throw switch is adequate. A household light switch will work fine, and is readily available at any hardware store. The audio detector will be used to assess signal frequency.
German Word Clock Thanks to Mike for sending in his German Word Clock. He has used some SPI controlled RGB lighting strips to make wiring and controlling the lights simpler. So that the letters look good he has built and installed an MDF baffle with 100 light holes in it. ”To control the clock, an ATmega8535 is used. This is a real-time clock (DS1307), a Bluetooth module and a Darlington array to control the 4 leds around the clock, each of which represents the minutes (Example: The Time Clock “It’s five after two” and two LEDs lights -> Thus, it is seven to two). - 40 × 40 cm, so that you can read the clock at a distance greater good
Circuitbending - Circuit-bent noise toys by Cementimental Towards the start of Autumn 2000, I was idly searching the www for experimental sound/music stuff. I chanced upon an article by Reed Ghazala, who explained the strange art of 'Circuit Bending'. This is basically a process by which anyone can make bizzare alien electronic musical instruments! The procedure is essentially to take apart any battery-powered (low voltage!) audioJar - SARAH PEASE DESIGN audioJar A simple housing for David Mellis' open-source Fab Speakers. Using readily available household items and basic construction methods allow for even further customization and flexibility of the Fab Speakers. Varying jar shapes/sizes can be mixed with alternate feet for different looks. "The glass jar design is “back-woods” charming while also marrying the modernist mantra of “form meeting function.”
Looping/re-triggering with transistors The drawing above shows one of the many ways you can utilize transistors in circuit bending. The transistor in this drawing is there to automatically trigger the circuit to make sound. The circuit shown is a generic sound board from a generic kids toy. Paper Circuitry at Home: Electric Origami This little LED-lit cube is much more than just a paper lantern: It’s a translucent and flexible thin-film electronic circuit that hooks up a battery to an LED, limber enough to be folded into an origami box. And the coolest thing about circuits like these? You can make them at home. In what follows, we combine basic electronics (an LED Throwie) and papercraft (a traditional origami balloon) to make what might be called an “LED Foldie.” The circuitry consists of aluminum foil traces, ironed onto adhesive paper such as freezer paper, photo mounting paper, or even a laser printed pattern. Something constructed this way can then be folded so fit an LED and battery to complete the circuit.
