I registered here to show something I made when I was 12 years old, and also to give you guys some inspiration, or even nice tips about the power supplies I used for my 12v motors.
The pic is a bit low quality, sorry about that but I read it is required. It's old and I didn't have pics of it, but the video shows clearly how it looks and how it works, so watch that one!
I used 2 x 12volt motors I hooked onto old model train power supplies. This is a great idea and I recommand it, it's much more fun and better controlable.
For the 3v battery motor I extended the cord and added a 3v ac adapter. Batteries are annoying if you ask me.
Also optional: some christmas lights and an electro magnet from an old playset, this is also hooked up to an ac adapter.
