So my 9 year old daughter has taken an interest in electronics, so we have begun learning together. Still basic stuff, but going well so far. We took apart a "flip flap" solar flower the other day to see how it works, and it is a very simple circuit, but doesn't make a lot of sense. We want to re-create this circuit on a slightly larger scale, but are unsure what's happening. A solar cell feeds a capacitor, leading to a small electromagnet which I thought would need to pulse in order to get the flower's petals swinging. I don't see what is modulating the flow to the electromagnet though. Here is what it looks like:
There is another brand that does the same thing, but with a more complex design:
Can anyone point us in the right direction on re-creating what's happening here? Either version?
Thanks!
