A small test bed for a fidget spinner. Ideal to show a bit of physics with it.
Simply connect a LED and LDR and start experimenting.
Connecting it to an oscilloscope you can do a good range of experiments:
- Calculate RPM (a bit of maths needed depending on the number of arms the fidget spinner has.
- Observe friction and deceleration. Measure and see how after each turn, the width between pulses shrinks.
- Calculate angular velocity.
- Learn to use the horizontal axis of an oscillosc
