Teeny Toothbrush Robot

Linus has been taking a class this week on circuit design. At first he was mad at me for making him go to school after school is out for the summer, but he’s been enjoying all of the projects. Each day he comes home and demonstrates what he makes, and teaches us the new vocabulary words he learned. Today he said to me, “And this is tape, which is something called an ‘insulator.'”

So far he’s created a flashlight and a game, and now we have a teeny robot that vibrates around the house on toothbrush legs. I convinced him to make a little video to explain how it works. My favorite part is that at one point he notices there’s a hair on it, and is disgusted. That’s my boy!
