Hackaday posted about this great educational project to build a clock that makes it easier for kids to learn how to tell time. Check out more information here.

My daughter is about 2 1/2. She loves learning about colors, shapes, animals, dinosaurs, and all sorts of other things. However, she’s still too young to understand how to read a clock. But now is a good time to start teaching her.

We wanted a clock that would change colors based on what it was time to do: play quietly, go to bed, get up and play, pick up toys, and so on. Here is the result:

To start, I purchased a wife-approved, battery-driven clock from a local retailer for about $10. This one was perfect for me: it has plenty of room inside, a nice, big face, some weight to it to hold it in place, and, to top it all off, it matched the wall.

OK, enough introduction, let’s get down to it. I’ve got a Pi running a baby monitor (another project, another write-up, but the LEDs in the lower left corner are a super bright infrared spotlight for night vision on the cameras), so I’ll be driving it from that. And I’ve got some ShiftBrites leftover from version 1 of my DIY Ambilight (scroll down for more info on that project). Perfect. Let’s build.

Check out the full build here.
