Maquettes and sketches towards the realization of final development:





The final construction will be a harmonograph that will feature 2 pendulums that will move in a perpendicular motion. The maquette I constructed could not handle the weight of a pen; therefore, could not be used to to see if the mechanism worked. However, the basic structure will be similar to the maquette. Specific materials and mechanism are do be discussed and established.
