Light painting with 19th century inspired plotter

Posted on August 16, 2021 by William

A geometric chuck is a device that stacks multiple rotating wheels. These wheels can change their speed and their offset from the central axis in order to use a lathe to process gorgeous designs.It was this 19th century processing camera that inspired the inspiration This light painting is from [Ted Kinsman].

Instead of the complicated gears and wheels used in the distant past, [Ted] Instead, choose to use a stepper motor. Three stepper motors are stacked together, and each motor can rotate at an independent speed. This design only implements three steppers, because the slip ring required to send power and control signals to each stepper is very expensive.

An Arduino is programmed to run this program, changing the speed of each motor, thereby changing the pattern generated by the system. Put the light-emitting diode on the rotating plate, or install a pen to mark on a piece of paper, you can produce various beautiful spiral patterns. Change the motor speed or the position of the light, and the pattern will change in turn.

This is an interesting light painting build that produces some great visual effects. We also appreciate the use of Arduino, which makes changing the parameters much easier than changing the gear set in a classic design.

If you missed the old-fashioned spiral gauge, you can always make one out of Lego bricks. Otherwise, please consider trying other light painting techniques. If you have built your own exquisite drilling rig, please let us know!
