Brian Degger explores technology, art and other things…
Processing.org has a nice video capture library that is suitable for quick videos for documentation, I am using it to capture some arduino experiments with the external isight camera
code follows….

I was at Mashed08 in Alexandra Palace . There is a good mix of hardware and software hackers, but I like the hardware ones best. It’s a bit like working with children ands animals. It should not be done in 24hrs unless you are really experienced. I spent too much time on a prototype when i should have spent time on the sketch, A learning experience, but I did dip into using python to talk to Arduino , and that was a valuable lesson.

I recently bought an asus eeepc subnotebooks( 4G ssd, 512ram, portable celeron) for a portable blogging computer. I never expected to install processing.org or arduino even though I use them on another computer. However, the people down at the eeepc wiki have posted a method of installing both(here) . I have installed arduino and processing(instructions ) on it. So now I have an ultraportable kit to play with arduino and processing! >> 2kg! Its not a fast system for processing, but adequate for trying out patchs, and fine for communicating with arduino.
Cool.
Now I am working with the kingbright chameleon rgb led modules(available at Maplin and Rapid ), getting arduino to handle the physical interface of controlling the 3 leds(on/off done) and processing.org the mix of colors from an onscreen interface(in the process).
To do this I have used the example code from fading and blink, and merged the different ideas.
I hae also been getting to know led modules, their orientation, the value of the resister needed for each. (ie the Blue operates at a higher voltage than the Red led, needing different resister values).
This is primarily because LEDs do not provide a resistance to current, if the voltage is above the operating voltage of the led, then the led will suck more and more current until it burns out. Thats the reason to put in the resister, it controls the current (usually 20milliamps up to a max of 50milliamps)(some links can be found at http://del.icio.us/sctv search for led.
Will post the code as it gets more mature, for now I am verry happy to have this nice little development package for arduino and processing.

EEEpc and the removable media
I have a reoccurring trouble with the removable media, sometimes it says that I don’t have permission to write to the internal card reader or anything removable. The problem is that the /media/ directory has disappeared, you need to go into the comand line/terminal and recreate the directory
sudo mkdir /media/
should work if you are in the top directory.
I also had a problem where the shortcut to the internal media was corrupted and was showing an old state. To get rid of this, take out the card, and delete the shortcut, it will get recreated when you put the card back. (0)
Eggpass
Eggpass Lo-fi social networking. Rosanne Marshack and Richard Valentin “On Augmented Reality-Enabled Social Network Traces of Pratitya-samutpada (Interdependence)” were tracing their social network with 12 black eggs.
These eggs were simple to make, nice to hold, but at some point the paths stopped. The participants had become too attached, the eggs became objects of affection and didn’t go any further. (0)
ISEA - Aceti mediated virtual visions
abstract Aceti and collaborators are developing a technology that can look at how virtual reality affect emotions. It is his goal to get to an experiential idea of how to affect emotions. He is actually trying to measure the responses, eeg, perspiration, etc, the reaction.
This is quite a powerful idea, but one that comes into all artworks, but I don’t think it has actually been done for art at a quantitative way. (0)
Ping
In the PING, an alternate reality of control (Eelco Wagenaar, Arjan Scherpenisse) talk (abstract here). It was exhibited at mediamatic amongst others.
Games are about fun rather than winning. They have made a simple ping game, simple in technology, but not content. The structure is two pingpong ball throwing devices and two players, two screens, and a small bit of software. (1)
12 hours and 8 time zones
Ah, Singapore, where the weather is balmy. Its my first Asian country. My fellow passenger David from www.xm-asia.com described it as Asia on Training wheels. It is certainly that. I was at the Sleepy Sams only an hour after getting off the plane, no queing for passport control, bag already on the luggage carousel, easy to obtain travel card, and quick. Compared to the hours lost in other countries post the plane, this was great. Now to tell my body that it is not 1.30 in the afternoon.
So now off to find some food…probably Malaysian. (0)
