Three's a crowd
Pendulums infuenced by magnetic attraction. Inspired by Mark
Espar's "A Circle of Friends discuss James Clerk
When a pendulum is at rest, a hall senser causes a Picaxe
microcontroller to trigger one of 3 coils around the senser.
Random on times and delays are used to keep the pendulums in motion and
to change the patterns that are created. A white led inside each coil
box indicates what coil turns on and how long it is activated.
Each pendulum will repel each other. The coil polarity is
attractive. Mosfets are used to turn on a coil and led in each coil box.
