solar motion in two parts


with Marc Wejda and Leonhardt Helm

After the construction of a color solar cell with household resources, a kinetic object should be created. Instead of optically indicating the intensity of the light, we translate light and dark into acoustics. Where rotation and sound merge, the vinyl record is not far away. A paper funnel with attached needle is sufficient for the light solar record player.


In the second part of the compact week, an autonomous wheelless vehicle for a 4-metre course had to be constructed. Due to the inefficiency of the given motor and the solar cell, complex running mechanics were not effective. Therefore, two vibrating solution approaches were worked on at the beginning. However, the variant based on three toothbrush heads had greater problems with the obstacles. Therefore, I increased the underlying principle of locomotion and replaced the bristles with vibrating legs, which better determine the direction of movement. I reworked the vehicle several times and lasered it out of 0.5mm thick polypropylene foil, which is stabilized by the solar cell. The drive is mainly by vibration, which is caused by the imbalance of the propeller. My final model is only folded after the laser and put together with motor and solar cell and managed to overcome the course.
