Homemade Double Pendulum Kinetic Art


Step 1:

Step 3: Circuit

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 LED 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

<p>This looks cool, but, as other point out, there seems to be a lack of details. I don't see any real description of the circuit or how to wind the coils, etc. Please fill this in to make it easier for others to build.</p>
<p>What kind of circuit? I was expecting something like the inner workings of a clock mechanism.</p>
<p>This looks really cool. Could you share some more text descriptions on the step to make it?</p>
