technical description and making of
Kreisverkehr (Traffic Circle) is based on the idea of an antique phenakistoskope, but instead of small observation slits, a photo diode reads the information of the passing by images, and emits to a microcontroller this information. The controller starts an ultrabright 100w LED to emit a flash for 1ms and the slide will be projected.
The projection is divided in two parts and shows a highway in the south of Tenerife/Canary Islands. Each carriageway is covered by one circle with 120 slides. The result is a loop of around 10 seconds. The aesthetic of the image reminds of the first moving images.
First drawings of the installation:
Sketch for the construction of the structure
All the lenses have to be adjustable in four different directions to make the composition possible
lenses are taken of old slide projectors
structure at the workshop
The drive mechanism is made by windscreen wiper motors, parts of bicycle, cooling fans of a computer and industrial bearings.
Calculating the dimensions of the Circles, still of the old school by hand....
CNC Cutting of the segments for the circle.
projected film loop
The film loop will be composed by 120 slides for each circle. The image is shot in LasAmericas/ Tenerife.
The images are digitally retouched to give a smooth loop.
100 W LED, 6500 Lumen .Directly ordered from China.
But as the LED only flashes for 1ms the LED cannot get its whole brightness.
Electronic components inside: motordriver and speed control for the wiper motors, 12 V power supply for the motors, 9V power supply for the microcontroller, 2x AC Drivers for the PowerLEDs, a DIY microcontroller board with an Atmega16
