here it is, with external casing holding the arduino board, a 9V cell and the shift registers. version 1.0 will be self-contained using an arduino mini and a smaller and stronger power cell. at the moment the system is running for approximately 1 1/2 hours on a fully charged battery.
Here it is, still some unreliable contacts, but i will fix that tomorrow…
32 Ultrabright LEDs in a beautiful casing hand-crafted out of brushed aluminium by tim horntrich
a long exposure shot taken… a radioactive symbol is clearly visible.
since the image is flipped by changing the direction of the eye movement, only symetric motives can be used to avoid confusion when using the pov device in the “headshaking” stationary manner. therefore, the motives chosen should be easily understandable, they should be of a symbolic kind.
placed next to a highway and showing crosses, the POV device reminds drivers that speeding kills, the faster they drive the better they can see the crosses
the 32*32 LED code and hardware finally works… after finding out that a 2dimensional array of booleans uses all the RAM of the Atmel on my Arduino board, i was told that i could store the image data in a 32-field-Array of longs. it was a little bit tricky to figure out, but i wrote an processing sketch that outputs a series of longs to the console generated from a .gif image which can then be copied into the arduino program.
