You can create a pulse motor using solar swinging toy circuit (swinging sunflower, swinging monkey, dancing catus, etc. ) Solar swinger circuit has an autostart function and large coil resistance of 500 Ohms allowing to operate from room light. After extracting the electronics from a toy, protect the thin windings of the coil with some sticky tape. And fix the solar panel with some hot glue. I glued the exciter to a wooden cube and put under it some plates to increase the height and come in same height with the magnets.

I prepared 3 similar rotors in one evening. It was a surprise that they experienced a chaotic motion behavior when feeling each other similar to coupled chaotic pendulum.

Solar rocker toy could be any. Magnets and light bulbs can be bought from Aliexpress. Light bulbs can also be bought in a gas station. Needle from your mum's drawer.

Pulse motor rotor can be made from some large lid (search lidmotor on Youtube). I think it is nicer idea to print a low-weight Ferris wheel shaped rotor. See the attached stl flies. Files were quickly made in Tinkercad and published also in Thingsiverse.

You will need the file with 1 mm hole for holding the needle. And another file with larger hole that will hold a glass meniscus from a light bulb (e.g. car 1.5W bulb with 5 mm diameter or 3W, 4 W bulb with 10 mm diameter). Light bulbs are saw open with a diamond disk used for tile cutting. Edge quality is not important. Glass section is fixed in the rotor with some hot glue. The tip of the needle will rest on the meniscus of the light bulb and have amasingly small friction. I measured that a rotor could spin up to 8 minutes.just by inertia.

It is nice to use 10 mm neodinium magnets. N52 are the strongest but weaker will also be OK. Larger diameter magnets will spin at less light. Magnets are spaced every 90 degrees around the wheel. A coupe of magnets is used so that the are held by attraction to the wheel. So you will need 8 magnets: two for each pole. All magnets have the same pole facing outwards. Mark one pole with a permanent marker. Experiment with the number of poles: try just 2 poles and 3 poles, and more than 4 poles.

Magnetic pole direction should be chosen such that magnets get repelled by the solar circuit. It is easy to fine-balance the rotor by slightly sliding the magnets on the Ferris wheel.
