Three miniature servo motors control the arms of a pantograph assembly. Mechanical parts of the Sand Clock (a refined project based on an original idea from our friends at Make Magazine) mainly consist of pieces of acrylic sheet, a material readily available and well suited for laser cutting. The use of metal gear servo motors provides high accuracy with acceptable slack.
Make & Elektor
The idea for this project originated from our friends at the German Make Magazine who in turn were inspired by the plot clock from FabLab Nuremberg. It was selected in our first ever joint (Make & Elektor) hardware meeting to become one of the first projects to be refined and built into a kit by Elektor Labs. The result will be published in Elektor Magazine edition 1/2017 (January & February).
Watch the project demo'd live at electronica München 2016, November 8 – 11, Booth EOE 200, Entry East.
