The synth has taken on a life of it's own. The pd and the arduino has gone by the wayside. Comes down to solder experimentation. The video is blipping and zzzzzzrrring the circuit bent toys and the toyz are square waving the visuals and hyping up the colors!!! Just hoping I can create the schematics of the birds nest of wires : (

I figured out that using Pduino and Firmata makes the interactive element of my project seriously easy. Using a Pd patch I constructed along with Mr. Alexandre Quessy, for a project early last year that controlled Video loops with Audio data, I created a customized patch to detect certain frequencies that I want to trigger the visuals.
I have yet to even explore what I can do with the other 10 pins, I have had such great success with the first five. Through the Pduino test patch I am feeding data to both the h and v sync pins and the RGB as well. On an old monster of a monitor I scrounged I get three different sort of varieties... two tone horizontal split with acid fuchsia, green, yellow, blue, black and white flash, a jittery sawtooth dancing jotting lines in predominantly black with acid of the same, and my favorite a fading multi tone szeisure inducing natural earthy tone slide show of color.

The VGA synth, has gone through some major transformations. I have gotten the adapter (vga to s-vid/ comp) and as I suspected this did not result in the picture I want, (color has been depleted to almost nill : ( ) I am going to have to scrounge up a scan converter (can't wait to jam with this, need to record!!!!) For now I can bare with recording my monitor but to use it for video I really need it to have an s-vid out. As a temp. solution I have decided to build this for both black and white and color. (I can still get some pretty phat psychadelic shapes in black and white with the simple vga to s-vid adapter) I will box it up and have three vga connects going in for variable syncing set ups and have two vga outs as well. The box will also have RGB controls to fine tune.
Anyhow I am using the files from http://www.arduino.cc/playground/Interfacing/PD to talk to the arduino through PureData and Frankensteining a patch to analyze the sound coming in.
Plans for the weekend? Play around with the remaining untouched VGA pins, shrink tubing some wires all in all making the whole thing a lot easier to work with and cat-proofing it a little too. Tim found some great wooden boxes that I will mount the whole thing into!

It did not take long to realize the snipped vga cable was not the most efficient way to go, so I made my own, connecting the v and h sync to a female and male end. I connected wires to the RGB pins and connected those to the pots. The following links are projects that helped me out, the first is where I found the code that I started out with.

And of course where it all started, Brian's untouchable VGA synth.

I have resolved my syncing problem by stealing the sync from another monitor, much like Brian's synth. I am still messing around with the code. Once I get some colours I really like I will switch the pots for audio signals!
Here are some videos that capture the ranges of colours and patterns I have so far (the footage is poor quality, thus far the synth only has a VGA output):

I picked up the pots at B & E today, and added to the previous code in order to generate some sort of sync signal. I found with only the RGB and the ground connected the colors quickly fade to black but once fed a sync signal we get a bit of a pattern and a little more consistency. CHeck out the bit a managed to catch on my cheapO 5 MP digi cam before the batteries died.

I was really excited to get this synth working, I finally obtained a VGA gender changer after checking 5 different places in Saskatoon resulting in 5 "what's it for?"s proceeded by blank looks, oh but the fellow at London Drugs thought he could order me one for around $30!!!!! yah right. To my suprise, my AWESOME boyfriend Tim came home the next day with one that he found at Top Logix for $6.99
Most recent sitch is no 50K pots, errr, first thing it's closing time so I go straight over to Rose's Auction, she almost never fails me, for my speak and spell bends I found the pots I needed, 2 of those and 3 switches for a buck! But alas, 2, 10, 250, 500 no 50. I check The Source, to my splendor the response I got from this sprightly young chap was "no," awkward pause, " wait what is that?"
So tomorrow I will have to go to B & E where I will likely pay $20 or more for 3. Meanwhile I will play with resistors and buttons, try to patch my noise generators to my arduino and think about coding, maybe consult with one of my genius coding friends Buzzy, because my head is spinning just thinking of where to start.
If anybody has any links or info about projects having to do with VGA, VGA hacks, VGA video synthesis and especially VGA and Arduino projects, and code I would really really appreciate it.

I have tested the plan and have had great results, I can trigger red, green and blue screens. Now I will feed the circuit the data from an audio signal, then add pots and other controls for varying patterns and colors.

I have begun with an Arduino, some second hand code, a little max/msp ditty and a butchered VGA cable.
When it comes right done to it, I have no idea what I am doing. I do have a plan. I have installed a the following code on my Arduino Diecimila
byte data1 = 0;
byte data2 = 0;
int dT = 0;
void setup() {
Serial.begin(57600);
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
}
void loop() {
if(Serial.available() > 1) {
data1 = Serial.read();
data2 = Serial.read();
}
dT = data2 << 5;
PORTD = data1 << 2;
delayMicroseconds(dT + 1);
PORTD = (255 - data1) << 2;
delayMicroseconds(dT + 1); }
which is supposed to send out data to the RG and B pins of my VGA circuit. Once this proves correct I will connect my audio signals to my computer, introduce them to my Max patch and hook them up with my lovely Arduino friend! these guys together, I figure will provide me with some pretty pictures : )
Throughput Project
2008
work in progress
This is the result of a digital arts residency at Paved Arts, Saskatoon, SK. A program called Throughput more info: http://www.pavedarts.ca/workspavedproductions.php?gallery=leeane_berger http://wiki.dataflow.ws/PavedArts/LeeaneProject?highlight=(paved) An Arduino based controller, contruction of which involved the skillz a pizazz of Darsha Hewitt http://www.darsha.org/ and ALexandre Quessy http://alexandre.quessy.net/
