in thinking about the design of the unit, we want to create something that is ambiguous in time, a magic machine that could come from now, or a past or future time and that does not look just like a computer.

I am inspired by the KitMobile, a set of mobile suitcases containing electronics and video screens by Montreal artist Line Nault.

Dan also thought about the process, how it can be visualised by the users and we decided that we prefer not to have just a line of LEDs, as a meter, but rather to maybe use a needle/dial style meter or integrate lights in the unit in a way that better fits the 'possibly old' look of it.

Edson, from Lima is at work on the Python coding. He managed to see what Marius and Patrick have started and thinks that its possible to qctually collect and process pixel data from each image quickly, mostly using python. Of course there are some libraries missing on the eee so he's looking into that today.

Also, very importantly we discussed the waiting time of the user and ways for them to better physically feel the processing. Dan suggested a  metal wheel crank, something like those used to lower and raise table saws and other shop tools. Now we're looking for a nice old metal wheel.

Yesterday we took a field trip to a huge electronics market. We got a little waterpump, the style used for cars, but it was dead. We made some tests with the pump that I have brought with me and this seems to actually create enough pressure.

1st water test with the electric submerged pump, a good start

We are now considering a water system of small falling raindrops, a curtain of water, rather than an upwards spray... but we might find that this spray may need to go upwards since gravity with cause the falling drops to get bigger and in order to create little rainbows, we need little drops.

nice pressure tube we made last night

Today we will install a hose on the balcony and play with water. Its a perfect time for this because its VERY hot.

For the water component, what about a garden sprayer type deal?
They produce a good mist like spray of small water particles.

It could be made with a small 12v car compressor, a pressure holding unite (car tyre, propane tank, array of 2l pop bottles), a water tank and the nozzle(s).

I guess the water is being recuperated, it be tricky with this system.

And the windows that contain the Rainbow, how will we work around the build up of water on them?

the eee is running ubuntu now.
I have been having troubles with this machine and image processing... with GEM there are opengl problems.
Now I started to consider other ways to draw data from the images... maybe convert them to text files and count some data from there. va e to think of the poetry for doing this... for deciding what data to draw out and count up.

Hi folks!

I look forward to collaborating on this project. My field of expertise is designing/building with scavenged resources and arduino. I also have a fair amount of knowledge in robotics.

I also use an eeepc (701), what will ti be running?

cheers,

HI, some more specifications:

I have been working on the Rainbows project and found that I will need some help especially in these programming areas:

- python (image processing)
- OR processing (image processing and talking to arduino)

I'm using an asus eeepc for this installation and keep running into some issues with Pd/gem. I originally thought that was going to be the best way to go, but with this hardware, I think it will be best to work on another solution.

As for the other aspects, would be great to have some expertise in:

- light/optics for rainbow making
- construction/plumbing, for the water system and insulating the electronics
- design (object, for the unit + graphic for the signage)
- electronics

feel welcome to post here or write to me if you have some questions.

hope to see you in Lima,
Kyd
