I occasionally volunteer with the Big-Brained Superheroes Club, an after-school program for young people. The other day, the kids were learning about binary numbers and I thought to myself, “Self, you should build an electronic binary-to-decimal converter, with LEDs and toggle switches. Yeah!” So I did.
Well, building it was fun, and I could spend all day flipping those toggle switches up and down, but the real test was seeing how the kids would take to it. Let’s go to the videotape:
By George, I think she’s got it! Read the BBSC blog post.
Btw, the device needs a name. If you have a suggestion, leave it in the comments below.
