Introduction: Double Pendulum Perpetual Kinetic Sculpture

Double pendulum perpetual kinetic sculpture

Step 1: Make a Box

Step 2:

Cut aluminum sheet in this shape shown in images.

Step 3: Thing U Need

Thing u need The circuit uses a few common parts:

NPN transistor 2N2222

PNP transistor 2N3906

Diode 1N4007

Resistor - 1-100K

1 Meg preset resistor

Capacitor 3300uf and 1000uf


Battery 2 AA alkaline cells 1.5 v

Coil 28 gauge copper wire (500 turns ) 1/4" inner diameter

Magnet 10 mm × 10 mm

Ball Bearing id 4mm od 8mm w 4mm



honestly im sure this ain't perpetual,Its just a design.IT will slow so its not perpetual
