Circuit Bending Tutorial

What is circuit bending?

Here you’ll find pictures, tutorials and general info on circuit bending.
If there is something specific, pertaining to general circuit bending practice, that you would like me to address on this page please feel free to email me at pete[at]casperelectronics[dot]com

Topics I plan on addressing include what and where to buy tools and components, touch sensors, general rules of thumb, what to look for when buying toys for bending… and more.

Pitch control is one of the most important bends to learn about. Info is available by clicking the pitch adjustment link below.

    Hey, just wondering if you have ever bent a “zoom ps-04” track recorder? and or if it is possible to bend one. its a pretty cool gizmo, thought maybe you could since it has guitar fx built in and drum beats. if you have got any schematics? thanks.

    @frank: sorry, never played with one of those before. I’d be very careful with this one…. small, complicated and cheaply made=easy to break.

    i’ve been bending certain kids toys and have hit on something that has muted the sound. any tricks i can do to get the sound back? reset maybe. tried taking the batteries out and no dice. i had a really cool loop going on one and kept exploring and blew the sound. i hope i can get it back. the lights are flashing the same as they did but there’s no sound…

    @Tom. Unfortunately that’s a hard one to debug. It could be any number of problems. Maybe the wire going to the speaker broke. The fact that the lights still work is promising.

    Hi there! Im almost a beginner… Ive done a atari punk console once, and worked with some 40106 oscilators. But now I wanna bend a Casio SA 46, its my first time on bending. Do you have any tip to distort its sound? Like a fuzz or something like that…
