Prava stvar, ja sam pokusavao napraviti ovo isto ali mi nije bilo efikasno. Nit sam koristio
ove magnete niti namotaj od releja. Moram i ja probati...

DIY contactless bike dynamo
It is very important to have lights on your bicycle but it can be very boring to replace those batteries. A classic bike dynamo has a few disadvantages such as slowing down the bike and making excessive noise while rubbing off of a tire. There are contactless dynamos, but why buying one when you can build one yourself?
This bicycle light is made out of three LEDs and a charge capacitor. It is powered by a DIY contactless dynamo made from a relay coil and some hard drive magnets. The circuit is constructed so that one LED is kept steady on while driving and the other two blinking.

Ovo je zgodno. Bilo bi dobro staviti 3 ili cak 4 magneta pravilno rasporedjena po obodu
zamisljene kruznice na kotacu. Tada bi se proizvelo vise struje.
