Gijs did it again with a totally whacked out hardware sequencer for visualizations. Basically an electronic circuit controls rollers that hold various visualization cans, which can be switched in and out as modules. The cans contain things like mirrors, kaleidoscopes, and colored string. The device also features a sequencer that can be programmed to flash a light bulb, control the camera position, and other parameters. Very neat concept, it reminds me a little bit of DrumBuddy. For video of this device you can click here. The visuals generated I can only describe as being totally drunk and stuck in laundromat dryer. Can’t possibly even imagine drinking and watching this on a big projector at a show. Nice work.
…of CasperElectronics.com. Pete demonstrates various methods for bending the NES system and goes into types distortions possible and the bending points like the Cart slot and the video IC. Very informative. The video was filmed for a Public Access TV station in CT making it the one program you do not want to catch late at night cause it will blow your mind! Thanks Pete.

This may seem a little trivial, however Maxwell went ahead and did up the diagram for hooking up a foot pedal to start LSDJ tracks on the original Grey Gameboy. Actually this diagram of the GameBoy schematic can be quite useful especially if trying to get some video glitches out of the unit. Notice the Video Ram IC.
Gijs of Geiskes.nl has just sent me some information on their recent experiments with patching signals from an Casio SK-1’s ROM chip to a video monitor. The circuit is simply a diode to prevent the back flow of current and a resistor to drop the +5 Volt logic gate to a +2 Volt required for generating a video signal. The color of the pixel is determined by the voltage in between 0 ( Black ) and 2 ( White ), so if multiple points on the ROM chip were mixed with various resistor values color images will occur. Gijs’ result is a series of lines that appear on a monitor in a scrolling fashion. The resulting image is neat and in sync with the sounds generated, however it is out of sync with the screen. The NTSC and PAL video standards require a sync pulse to be sent every so often, without it the image will scroll. Very nice work and I am sure that this technique will work with other circuit bent devices.
Video on of the bend is on YouTube.
