Circuit bending is the process of taking a small electronic toy or musical instrument, soldering wires to pads on the PCB, and hoping the sounds it produces will be cool. It’s not a science by any means, and any good, weird sounds you’ll get out of a Speak ‘N Spell or old MIDI keyboard are made entirely by accident or hours and hours of experimentation.
[Alpha Charlie]’s entry for the Hackaday Prize is the most technologically advanced circuit bending you’ll ever see. He’s using an old digital beat box, the Roland TR-626, with computer-controlled wires between random pads on the PCB.
Until now, you could tell how technically adept a circuit bender was simply by how many switches were on the circuit-bent instrument. [Alpha Charlie] doesn’t need switches. Instead, he’s using a few crosspoint switch ICs to connect different pins and pads on the TR-626’s PCB with an Arduino. All of this is controlled by a touchscreen display, and experimenting with the circuit is as simple as pushing a few buttons. Each ‘bend’ is computer controlled, and can be saved and recalled at will.
Of course, circuit bending doesn’t do anyone any good if it sounds like crap. [Alpha Charlie] doesn’t have to worry there. In the video below, he’s getting some very unique sounds that sound like a choir of angels to dorks like myself that listen to Nintendo music.

Circuit bending doesn’t get a lot of respect around some parts of the Internet we frequent, but there is certainly an artistry to it. Case in point is the most incredible circuit bending we’ve ever seen. Yes, it’s soldering wires to seemingly random points on a PCB, but these bend points are digitally controlled, allowing a drum machine to transform between bent crunchiness and a classic 1980s drum machine with just a few presses of a touch screen controller.
All circuit bending must begin with an interesting piece of equipment and for this project, [Charles], the creator of this masterpiece of circuit bending, is using a Roland TR-626, a slightly more modern version of the TR-606, the percussive counterpart of the infamous TB-303. The circuit is bent in the classical fashion – tying signals on the PCB to ground, VCC, or other signals on the board. [Charles] then out does everyone else by connecting these wires to 384 analog switches controlled by an Arduino Mega. Also on the Arduino is a touch screen, and with a slick UI, this old drum machine can be bent digitally, no vast array of toggle switches required.
[Charles] has put up a few videos going over the construction, capabilities, and sound of this touch screen, circuit bent drum machine. It’s an amazing piece of work, and something that raises the bar for every circuit bending mod from this point on.
Thanks [oxygen_addiction] and [Kroaton] for sending this one in.

[Berto] wrote in to tell us about the visual effects synthesizer he built. It works as a pass-through for a video signal, rendering crisp clean images into a more psychedelic flavor like the one seen above. On the one hand this does a dishonor to the high-quality video devices we carry around in our pockets these days. On the other hand it will make some really interesting background video at a party or at your local dance club.
This is not a filter for a PC, or an FPGA-based processing system. A set of analog parts alter the incoming composite video (NTSC or PAL formats) and pipes the result to a television or projector. [Berto] included controls to alter the effects. They’re mounted on a panel and everything is given a home inside of a handy carrying case. Check out the video clip after the break to get a better idea of the video manipulations this things can pull off.

This hurts our head
You know you can ‘freeze’ drops of water in mid-air by flashing a LED at the right time, right? Well, according to this video you don’t even need a strobing light; just use the frame rate of the camera. Much cooler if you don’t know how it works, in our humble opinion.
Now do Junkyard Wars!
[James Cameron] and [Mark Burnett] (the guy who created Survivor) are bringing Battlebots back to the Discovery Channel. The new show is called Robogeddon and calls upon the current talent in the fighting robot world. Our prediction? Someone is going to build an amazing piece of art that will be completely destroyed in the first round; a wedge with wheels will take the championship.
A steam engine made out of rocks
[Hansmeevis] just spent 230 hours hand carving a steam engine out of gems. It’s called “Dragon’s Breath” and it’s an amazing piece of work: the cylinder is carved out of quartz, while the flywheel, mount, and base are carved out of jasper, onyx, zugalite, and other semi precious gems. Amazing artistry and it works.
Don’t lose a finger on all that science over there
[Dr. W] is a science teacher in Saint-Louis, France. Next year, his students will be learning about reaction propulsion and impulse conservation. To demonstrate these properties, [Dr. W] hacked up an old vacuum cleaner in to a jet engine and built a Pitot tube to measure the 140 km/h wind speed. Google translation.
Circuit bending a Sega Saturn
Making cool glitched-up graphics from Ataris and Nintendos is old hat, but not much has been done with circuit bending slightly more modern consoles. [big pauper] found his old Sega Saturn in his grandma’s attic and wondered what secrets this forgotten box held. It turns out he can make some pretty cool sounds and even cooler glitched out graphics. The pic above is from Virtua Fighter; done correctly these glitched low-polygon graphics could easily find themselves in a very stylistic indie game.
[vtol] has built a very elaborate system of electronic sound machines, which can be patched together in various ways in order to create all sorts of sounds and sound effects. The modules range from simple noise synthesizers to pitch shifters, sequencers, and effects processors. The most recent addition to his synthesizer system is a matrix sequencer named 2112, which focuses on generating random sounds from a very familiar mechanism.
The sequencer simulates Conway’s Game of Life, representing the colony movements in beeps and buzzes, creating a nearly infinite array of random sound effects. Using firmware from the Game of Life board by Ladyada, the sequencer generates different sound patterns based upon the number of colonies on the board. The output varies according to the shapes and proximity of the organisms to one another. Since it is part of his already modular system, the 2112 board can be combined with any number of his other sound generators and effects machines to make all sorts of circuit bent music.
Keep reading to check out the trio of videos below demonstrating the Game of Life board in action.

Sadly, the video above is the only information we were able to find on the “Double Slide Controller” trombone, built by composer Tomás Henriques. As well as, the instrument took first place in the Georgia Tech Center Guthman Musical Instruments Competition. Right in front of a Bluetooth bow for violins, and a circuit bending group from New York, and…wait; it beat out our favorite modified didgeridoo? Better luck next year.
Apple Magic Mouse on Windows
Looks like some folks snooped around the latest Bluetooth update from Apple and managed to extract the Magic Mouse drivers. Now you can use them to take this complex peripheral for a spin on Windows. [Thanks Juan]
Component jewelry: From geeky to gross
[Nikolaus] made a pair of 300k Ohm earrings for his wife. That’s three Brown-Black-Yellow resistors per ear. It’s geeky but in a subtle way. Much more refined than the gross outcome of this other guy’s crass nipple experiments. Need to get the image of nipple-jewelry out of your head? [Nikolaus] has you covered with some 3d printed earrings.
Need your GPS data to be accurate within a centimeter? We don’t either but if you ever do, Real Time Kinematic GPS is what you need. Now you can build one yourself using the RTLIB package. This is based around the powerful and powerfully-inexpensive Beagleboard. [Thanks Jan]
It warmed up here a bit this week and things got slushy. Our Galoshes are nice and water-tight but [David’s] have a big hole in the side and are filled with a mini-keyboard. He’s chosen a rubber boot as the housing for a circuit-bending project. It’s a nice touch that the hidden keys are still playable through the flexible rubber.
