After two intensive days building, making the lounge look like a bomb’s hit it while Soph is away, I’ve got a working machine for some aleotory drawings of journeys.
I might have to add weight to the swinging drawing surface and I have to work out a way of a) attaching it to my bike rack and b) securing the paper. Then I should experiment with pens I think. You can see a hole drilled on the extension of the pen arm. This is to counterweight the pen, reducing friction if necessary.
Hopefully results to follow soon.
