I used to love yo-yos. I played with them all of the time and got pretty good at it. When I saw this little project over at Make:, I thought about buying a yo-yo and completing it. The build looks really easy and the end product is a yo-yo that has spin-activated LEDs, meaning that the yo-yo lights up like a Christmas tree when it spins.
You’ll need some magnetic wiring, hot glue, 4 LEDs, 2 3 volt lithium batteries, and some clear CD cases. All in all, it’s pretty straightforward. You can head over to Make: to see how Eric Chu did his, or just check out Kipkay’s video below.
Of course, you could just spend $5 and buy a cheapo one made in China. However, I think that there’s a lot of satisfaction to be had from making your own.
