D-Mach 01


The first iteration of my pintograph drawing machines, using an existing record player and a fabricated gear system, this machine creates harmonic drawings.



Collograph


The second iteration, named for the latin word colloquium meaning conversation, the two driving turntables of this drawing machine are not connected but instead have two hand cranks. This requires two people to cooporate to generate an image. The large drawing was created using this machine, the user manual was made using a simulation I programmed in Grasshopper and Python.
