I have a small hamster on a wheel toy that I received as a joke gift. I want to wire it to run in my car when I turn the key on.
I know I can easily make that happen with a simple relay, but what I dont know how to do is to bring 12V power down to what this hamster needs without frying it.
It runs off of two AAA battery's.
Do i just need a big resistor make it happen, or is there more to it than that?
Edit:got it working. Thanks for help.. I should also mention that I did see the hamster in another car, that's where I got the idea, but modding it to run on car power is my idea.
