on closer inspection ... 

The motherboard carrying the processor is the smallest 'gum'-sized board on top of the slightly larger expansion board which carries the GPS receiver, audio. and connectors. To upload files we had to use the serial connection (USB didn't work with this combination of boards, and there were other problems with bluetooth), Jorgen made a beautiful hidden connector that sits between the two boards. The whole thing is secured tightly by waxed string. The next stage was covering in rubber shrink-wrap - material that shrinks when heated to protect electronics, which gives the final form of the satellite sounders.

the Amsterdam prototype 
the second prototype showing the wrapped gumstix and GPS antenna, without battery and headphones, gives an idea of the modular form of the final sounder

Berlin prototype! 
Last week I collected the prototype of the GPS/sound instrument from Sukandar's studio in Berlin. These photos show the bare boards receiving the GPS data and converting it to sounds using PDa. It's tiny! The plan now is to build these elements into an integrated instrument.

intuitive sailing 
Error text.

balance and continual shifting of sails and weight in response and anticipation of wind and sea shifts. the precision is intense - the more finely tuned the sailor and the boat, the better performance through the water. i like it as an example of a physical and mental engagement with an instrument (in this case the boat) and the environment, where reactions and anticipations are used at such speed that it is essentially intuitive.

(thanks to my brothers Patrick and Vincent for taking me out to get this shot and talking me through the racing and tuning details - they are Campeones del Mundo! Silver fleet Flying Fifteens, Mallorca 2007)

hand held navigation 
An astrolabe from 1525 from Nuremberg - I found it in the archives of the Utrecht University Museum Historical Instruments Collection. It has an engraved ground superimposed by rotating sun and horizon and transferable disks depending on your latitude. You/me are located at the point where the circles converge.
