A slow motion machine. Works by combining the action of an electromagnet that makes an object vibrate and a high frequency flickering light that "freezes" the motion.
Inspired to the timeframe from Cubic Print.
I put in my machine four controls that allow me to set:
- the frequency of the electromagnet (to better find a resonating frequency for the object you place in the machine).
- the duty cycle of the electromagnet (intensity of the oscillation).
- the phase shift of the LEDs (speed of the slow motion effect).
- the duty duty cycle of the LEDs (intensity of light).

- Early prototype:
The box.slvs file is a Solvespace 3D model that I made to sketch my idea of the enclosing box. Then Cristina Galeotti (fb page) optimized the model to make it printable. The STL file are made by her.
BOM:
- 1 Arduino Nano
- 4 10k potentiometers
- 2 1k resistors
- 1 1N4001 diode
- 2 NPN transistors
- 1 LED strip (NOT programmable ones, which are slow)
- 1 electromagnet
