Vga. Online : Glitchbox bends video in response to sound. Bildheinzer built this Video Circuit Bending Glitchbox, the “BGB-03″ to control analog video with music - Video Manipulation Unti reacting to incoming audio.The RGB colours are split and sent through 3 Effect ways which react to bass,mids or heights….you can choose by the patch cables which colours goes which way..
S-Video in/out RCA in/out Once the Glitchbox is calibrated to each signal, the visual effects are quite strong and surprisingly pretty. And this one’s not alone – Bildheinzer has produced quite a few glitch-strumentation consoles.

It started in French, but I figured since NTSC is used mainly in America and in Japan, English might be better suited for the topic. The basic setup is the same as the Arduino pong and the other topic. So this is just my "port" of what these guys did. I did build mine with a "structure" to allow adding pal support to be able to switch modes easily in the code. Disabling the interrupt timer I haven't gotten my code to work with cli() and serial so you'll have to modify lib/target/arduino/wiring.c (MAKE A BACKUP) like such: // enable timer 0 overflow interrupt#if defined(__AVR_ATmega168__) sbi(TIMSK0, TOIE0);#else sbi(TIMSK, TOIE0);#endif To: /* // enable timer 0 overflow interrupt#if defined(__AVR_ATmega168__) sbi(TIMSK0, TOIE0);#else sbi(TIMSK, TOIE0);#endif*/ The circuit That is...

There are a few things that are acting weird... #91536 by Matthieu Lalonde (mlalonde) Rickard's electronic projects page - How to generate composite video signals in software using PIC. How to generate video signals in software using PIC BackgroundDuring the Christmas holidays 1997-1998, I started on a small project, trying to generate a video signal with a PIC16C84.
I had seen some video clock generating video signals in software, and thought it was a quite interesting idea, and wanted to take it a step further. I didn't know much about video signals back then, I basically just had seen how a single scan-line works. But during the spring I learned more and succeeded in making the game Pong with a PIC16C84. I thought this was quite cool, so I made it available on the Internet, and during the summer I also made the game Tetris. Arduinopong (alastairparker) Who doesn't like pong?
After playing with composite video signal generation, the next step was to use if for something 'useful'.Programming was not difficult, but there were some challenges.Given that so much time is spent on generating the correct video signals, any major delays (1-5us) would cause the video to lose sync and nothing would be displayed. Essentially the code is multi-threaded, with the left players position being updated in one loop, and the right updated in another. Due to the timing constraints, I decided not to use any floating point arithmetic for the velocity of the ball.

TellyMate Shield TV out from your Arduino. This shield has the same core circuit as the standard TellyMate, but re-arranged as an Arduino Shield. It listens to the Arduino's TX pin (Digital pin 1). Just plug it into your Arduino and use Serial.println() commands to output text onto your telly! It's really simple to use... Serial.begin(57600); Serial.println("Hello! ") Further demonstrations (including screenshots), are available from the 'examples' page. The TellyMate Shield is stackable. An extension reset button is provided to duplicate the (covered) reset button on the underlying Arduino. New features: ArduinoVideo - binarymillenium - NTSC video generated with Arduino - Google Code.
So video actually isn't that hard to generate with the arduino given a few resistors and testing.
The most important thing is to generate 242 lines of consistent length near 62.625us or so with 5 us of that time being SYNC (0 volts) pulses, the rest varying from 0.3-1.0V to represent black to white colors, with a few microseconds of 0.3V black voltage before and after the sync. After that there should be 20 lines all at the SYNC OV voltage for a vertical sync. I noticed if the sync is a little too long or too short the upper part of the screen curves oer to the right or left - it looks like macrovision protection. The first thing I did was generate a test pattern, then generate random pixels and scrolling them in a loop. Batsocks - TellyMate Shield. New, updated Version!
