I want to design a yoyo that upon spinning, the energy from the spinning, can turn a mini generator inside and store that energy into a battery which then powers a LED inside.
From basic calculations, I have seen that I could probably generate about 10W of power per 'toss' due to the high rpms and the low friction in the ball bearing that spins. If the generator is only capable of 5W, would the wasted power affect the yoyo and overheat excessively? If so, how would I go about protecting the rest of the circuit such as the battery and LED.
I am a noob in electronics so please be kind.
