I have made substantial alterations to this page in an attempt to make it more technical and less of a first person narative or advertisment. This process is used by lots of folks that do not sell or publish their work and I though that should be emphasized, instead of referencing one of the only people who does publish extensively on the subject. I hope that this works better for overall verifiable information, and I have left all of the quite impressively comprehensive websites, so people can get all of the info that was omitted from this page. If anyone has any suggestions for improving this page more, I would be happy to colaborate or otherwise follow leads for better public info on a cool practice that I wish more people tried!

Somebody should put up some kind of picture, maybe just like an open circuit board or a bent keyboard. Just a suggestion.

Aphex Twin
I've removed Aphex Twin from "See Also". You could also place a link to Autechre, LFO or whatever glitch artist. Slowgaze 19:40, 21 July 2007 (UTC)

Circuit Blasting
The Circuit Blasting addtion looks more like an advertisement for a new recording and doesn't fit the goals of the section of "Innovators," which is about important historic developments. I reverted to an older version. --80.67.64.10 13:42, 30 May 2007 (UTC)


 * I'd recommend focusing on what circuit blasting is: how does it derive from circuit bending and how does it differ?  From what I learned using Google, this is something Strange Attractor (Mark Pilkington) and Disinformation (Joseph Banks) does, and I 'm not sure there's enough of a following to call it an innovation.  I'm not saying it isn't worth a mention -- you may find it more appropriate to have a separate article for it, and reference it here in the See Also section, not unlike Glitch music, which has a larger following.  Please feel free to discuss! --Wayn3w 12:12, 1 June 2007 (UTC)

Power Supply
"'As a general rule, areas around the power supply or large capacitors are avoided to prevent damage to the electronic system.'"

Isn't it fairly common to add variable resisters around the power supply, to lower the power input to the circuit (known as a "voltage starve") ?


 * Yes, you're right. Starving the voltage is a common technique, but short circuits in this area are more likely to cause damage to the circuits than shorting other areas.  It would be good to a little more about electronics before attempting this.  Perhaps this should be edited to be made more clear. —Preceding unsigned comment added by Wayn3w (talk • contribs)


 * I've removed that part because its inclusion made it sound more like a tutorial rather than an encyclopedia article. I think the best thing thing to do in this section is to briefly describe the process and be sure external links include a good tutorial.  --Wayn3w 16:40, 14 June 2007 (UTC)

Releases
I don't like the way Releases has become the External Links of yore -- a section of links. This will have to be edited to make more like an encyclopedia article (using seminal works only). --Wayn3w 15:47, 20 June 2007 (UTC)

That's it -- Releases will NOT be for promoting your own album. Instead, it should have research. At least a reference to the whirlygigs album should be included, since it influenced other benders. --Wayn3w 04:03, 7 October 2007 (UTC)

Style
"Since chance is key element to the practice of circuit bending, there is always a chance that short circuiting may result in undesirable results, including component failure. Never bend any device that gets its power from the mains (household current) to avoid the chance of electrocution." how many times do you use the word chance here and throughout the article? are you having a laugh??? —Preceding unsigned comment added by 86.43.66.87 (talk) 16:46, 21 November 2007 (UTC)

"Through circuit bending, the human elements of music are somewhat stripped away and instruments are left to their own devices which are chance and mutation. There is a connection between man and machine in ways that are unlike other man-machine pairings, the human modifies machine to facilitate the entrance of chance into the creation process, this entrance of chance into mechanical equipment or electrical circuitry in other fields is strictly avoided making circuit bending unique in its basic process." This might make good reading for an art magazine but it's horrible style for a dictionary. "Instruments are left to their own devices" ? "Connection between man and machine .. unlike other man-machine pairings" ? Maybe it would be a good idea to remove that entire paragraph or mark it as personal experience. 63.241.31.130 (talk) 01:04, 20 August 2008 (UTC)

WHY DID THE TIGERCLAW RECORDINGS GET REMOVED OFF OF HERE? That was the first real circuit bent label- Its a hallmark and brought so many of us benders together? — Preceding unsigned comment added by 97.83.231.59 (talk) 19:33, 23 February 2012 (UTC)

any explanations of what's actually happening?
Anyone up for some explanations as to what actually happens? I do know the majority of what is happening in most analog stuff is the changes to negative feedback loops, basically inducing positive feedback (which causes oscillation), as well as circumventing circuitry used for stabilization of gain stages, inducing motorboating, as well as simply tying digital sections to analog stages are the typical things causing this.

For instance, in a typical low/line level amplifier, a designer uses various passive elements to set things like closed loop gain, bypassing, components used for amplifier stability, etc.

A simple example is a basic opamp circuit, where the gain is set by feeding the output of the opamp through a resistor divider into the inverting input. Conversely, if one where to connect this feedback to the noninverting input, depending on the circuit topology, one would induce oscillations.

As a hardware designer, I do this quite frequently by accident; and years ago, from poor PCB layout practices.

High impedance circuits are especially prone to this type of "non-desired" behavior. If this is an art, wow, I really must have been a master of it years ago when I was using some of the early opamps for state variable filters... the noises I got out of that... ehhh. Thank god for SPICE modeling...

For instance, I can see a majority of the single cell devices that use things like 9V's, being driven into some sort of motorboating by simply grounding or connecting to arbitrary points in other stages, the rail splitter used to bias up the opamps to 1/2 of Vcc.

It'd be interesting to see these circuit bends and reference it to the actual desired circuit topology. I'd do it but I'm a bit busy trying to AVOID that kind of thing Wamnet (talk) —Preceding undated comment was added at 22:11, 21 December 2008 (UTC).

ET, Really?
I'm a little concerned that the picture of the prop from ET is inappropriate. The ET prop is a fictional device, and the film was made long before the term "Circuit Bending" entered common usage. Any picture of a circuit bent device would be preferable to this.
