Have a gander here! The interface is a great idea too.

Some of these are quite breathtaking.

I especially like bubble chamber and binary ring :)

You're totally right man!
intersection momentary - seems quite nice too!
substrate - is impressive too!

Thanx Pixel!!! nice find!

Looks like the Processing language is taking off for artists, This is really a step in the right direction for the unification of what we know as art and math.

Here is the main site. LOTS of demoesque examples.

yep!

LOTS of demoesque examples.
It is 3 years now I heard about Processing for the first time... but only early last year, while chatting with Gargaj/CNS, he pointed me out at some really cool examples for real demo effects done in Processing.
Since I'm a little too old-schoolish I haven't take it so seriously but I must admit that, as stated by Gargaj, Processing could be very useful to "rapid prototype" new effects.

Do you mean the flash link selector in HP?

Really clever and eye-catching... I think I have seen lots of those link-selectors back in 1999/2001

you could check if some of them are still working http://www.flashkit.com/sites/oct99.php (http://www.flashkit.com/sites/oct99.php)
one of the best I've seen back then http://yugop.com/ver2/ (http://yugop.com/ver2/) still lives today (with a lot of additional tricks) http://yugop.com/index.asp (http://yugop.com/index.asp)

Incredible, makes me wish I was better at math.

ah complexification :D An awesome website !

About processing, it's also a very useful langage to interface with an arduino (www.arduino.cc (http://www.arduino.cc)) : I got one for some weeks now and it's a fantastic little atmega programmer/interface :)

hummmm... interesting! I'm playing around with arduino too... did you develop some infrared barriers sensors? I'm looking for a simple sketch to use a couple of IR TX/RX then i need to sense the broken barrier. Have you some links to share? (all usual arduino playground use some kind of shield, i would like to do it with arduino alone and a bunch of resistors and IR emitters/receivers).

cheers!

Hum, never tried to code any IR stuff, i'm still playing with LED's ;D. Anyway, I do have some really interresting links (sketches, tutorials, etc..) but I'm not at home now. I'll post those links this evening ;)

Didnt know about that. Sounds/looks very interesting.

@Hezad: 10x!!! i'm taking a look at Spooky Projects (never noticed before...) Maybe i'll find  something useful here!

Actually I was looking for a simpler version of this project http://www.thebox.myzen.co.uk/Hardware/Sneak_Thief.html (http://www.thebox.myzen.co.uk/Hardware/Sneak_Thief.html), I just need a very simple circuit for the IR sensor... have you ever seen something to take as example? I'm planning to nuy the "Getting Started With Arduino" book from M. Banzi, did you have it?
ATM I'm driving a DC-Motor to run back and forth using PWM to make it accelerate and decelerate on both ends (just adapted some ideas from here http://itp.nyu.edu/physcomp/Labs/DCMotorControl (http://itp.nyu.edu/physcomp/Labs/DCMotorControl), here http://www.arduino.cc/playground/Main/DCMotorControl (http://www.arduino.cc/playground/Main/DCMotorControl) and here http://blushingboy.net/p/motorShieldV3/page/Example-DC-motor/ (http://blushingboy.net/p/motorShieldV3/page/Example-DC-motor/)), I would like to remove the mechanical switch i'm actually using and put an infrared barrier.

@Moroboshisan: I've attached one schematic here for you, I did it myself for one project that I did for my college. Not sure how much simple you need it to be but I consider this one very simple :)
The advantage of this circuit is that it doesn't suffer from another kind of IR interference (like solar or lamps) and have a range of around 3 meters if well positioned when detecting reflected signals.

You can easily adapt to your Arduino processor to check 0VCC / 5VCC, the PHSC38 sensor will switch it's output terminal to 0VCC when it receives a 38khz IR modulated signal.

@rbz: very kind from you, that's too much!!!... :) I just needed to sense the broken barrier (no analog values, just logic 0/1) for a distance of 5/10mm between IR Emitter and Sensor... no need to do any hardware debounce, I'm planning to do it inside the microcontroller.

Now I'm using this IR-Emitter http://www.robotstore.it/product/16/Emettitore-Intrarosso-TSUS4300.asp (http://www.robotstore.it/product/16/Emettitore-Intrarosso-TSUS4300.asp)

and this Sensor http://www.robotstore.it/product/17/Fototransistor-Infrarosso-TEFT4300.asp (http://www.robotstore.it/product/17/Fototransistor-Infrarosso-TEFT4300.asp)


errrr... did'm mean to turn this thread into an hardware oriented one...  ::)

Ah no problem people will understand   ;)

I never used Arduino board myself but looking at it's specifications and knowing that you want to use minimum external components, you can try using it's analog input (http://arduino.cc/en/Tutorial/AnalogInput), because you can use an IR fototransistor act like a potentiometer, if you want 0/1 (0V/5Vcc) logic you will need to make a proper interface for it (more components :)).

I never used Arduino board myself but looking at it's specifications  [...]
there are programmable I/O pins (cit. Each of the 14 digital pins on the Duemilanove can be used as an input or output, using pinMode(), digitalWrite(), and digitalRead() functions.), I just need to ensure that useful voltage doesn't remain in a undefined state...


... knowing that you want to use minimum external components
exactly, I would like to keep the component at the bare minimum...

I'm going to build a circuit like the one used into this encoder http://www.nex-robotics.com/products/sensors/position-encoder-with-ra-mount.html (http://www.nex-robotics.com/products/sensors/position-encoder-with-ra-mount.html)

I think It'll work just fine connected to a digital input.

Am I doing it wrong?
Title: Re: Awesome site for procedural art.
Post by: Rbz on July 16, 2009
It is exactly what I had in mind, it's better if you use the analog inputs, because the IR foto-transistor works linearly according to the amount of infrared light at it's base, ie the voltage at its output will increase or decrease linearly.

For simple applications the digital input can be used, but for more precise applications you must use the analog port and check its values through the software or make a better interface for digital input.

The sensor just needs to tell if the beam have been broken (basically I need it to check the position "0" on startup/reboot so, when the power goes, for whatever reason, away and the system reboots I need to reset the system reastarting from a known place... when the condition is satisfied the real main loop begins waiting from user interaction).

Once It's working I'm planning to pull the Atmega328 out of the arduino board leaving it alone with just the needed components.

sorry to bring an old topic back... just stuck on Gargaj Processing examples page... very oLsch00l, couldn't resist! ;-)
