Make Your Own Silicon Mold
Thank you, Jim, for posting this Instructable. I made a Gasparovic pendulum 17 years ago from his article in Nuts & Volts magazine. It has essentially the same circuit as the one you showed in your Instructable. The pendulum has been swinging away more or less continuously since then, changing the 2 AA batteries every 3 months or so.I thought many times of doubling the arms and making a motor of it, but your Instructable finally provided the motivation get on with it. Still wanting the pendulum to keep on swinging, I made a separate motor - shown in the video at https://youtu.be/TtR1g7dx-pE . It runs beautifully and I thank you again for your help…TinkerJimPS: I slightly modified the circuit as shown here:

What a great idea, Joen ! So I tried it out last evening with the quick makeshift setup shown in this photo. It easily and brightly lights up a white LED, which can be seen if you look for it just above the generator. The flywheel should have more mass to give smoother operation when driving this kind of load. I also tried using a stepper motor with diodes for the generator. These are very effective generators and work well at lower speeds. Accordingly, they take more torque to drive so I connected the stepper shaft directly to the Finger Engine shaft. It worked just fine also, but again a heavier flywheel would improve the demonstration.
Would you cast the base with the bearing pillar and fulcrum pedestals as one piece? That would make it easy to finish; just drill two holes - and a little filing of course. The flywheel would probably be an easy casting and have a healthy moment of inertia. Would you make the lever and links of wood?

Yikes!! Just hooking up a 6 Volt battery pack is a good way to overwhelm the solar engine, but not a way to “test” it. The essential purpose of the solar engine is defeated. Best test it with the solar cell you are going to use with it! A battery source could be used for some testing, but only if a resistor is put in series to limit the current to the approximate level that a little solar cell would give. With only 2200uF storage, try a 10K resistor so that the cap will charge slowly enough for you to watch its voltage via a high impedance voltmeter across the cap leads. You’ll be able to observe the behavior of the circuit as the turn-on and turn-off voltages are reached. And double-check your circuit to make doubly sure that the wiring is correct and that the pola...see more »Yikes!!
