Did you ever have a favorite toy like an action figure or doll that could light up, make noise, or move? This project will show you how to make your own interactive toy using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. The version you make does not have to be a robot; it can be any shape and have any sound effects you want. IMPORTANT: The instructions for this project were originally written using Scratch 2 on a Raspberry Pi 3B+. If you are using a… Read more

You probably know that you can use iron filings to reveal the magnetic field produced by a strong magnet. If you sandwich the iron filings between pieces of waxed paper, you can make a permanent record of your magnetic experiments (Gardner, 2004, 66). Cover the wax paper sandwich with a layer of brown paper (from a roll, or cut open a paper shopping bag), and then (with an adult's help) use a hot, dry iron to seal the waxed paper together. You will have to experiment a little with your iron… Read more

Have you ever seen night lights that automatically turn on when it gets dark? What about art projects, like paintings or sculptures, with embedded lights? This project will let you combine the two, by adding lights to an art project of your choice. You can make the lights automatically turn on when it gets dark using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. IMPORTANT: The instructions for this project were originally written using Scratch 2 on a… Read more

This is a good project for someone who is interested in both electronics and color vision. The equipment needed is on the expensive side, but if you continue studying electronics, you can use it again and again. Read more

If you have ever built an electronic circuit with a soldering iron, you know that the component leads get hot. How much of that heat gets into the device you're soldering? This project shows you how you can use a silicon diode as a temperature sensor to find out. Read more
