Introduction: How to Make Modular Magnetic Components

technology is great. But there are times when we need to prototype or make something but we just don't have the time to breadboard or solder it together. Solutions for this problem like little bits or snap circuits already exist but they have hefty prices tags. So today i'm show you how to make a easy prototyping tool using household item and some of your components.

Step 1: What You Need


  • Foil
  • Magnets
  • Cardboard
  • Some Components of Your Choice (I used a resistor)


  • A Hot Glue Gun
  • Scissors
  • Pliers/Tweezers

Step 2: Prep

First plug in your hot glue gun so it will be heated up by the next step. Make sure to put a piece of paper under it. Then take your scissors and cut small squares of foil and cardboard.

Step 3: Making a Connection!



Hot glue guns heat up to more than 200 degrees fahrenheit. They can easily cause burns. I am not responsible for any injuries.


After your hot glue gun heats up pick up a piece of foil and a component and press them firmly together. Hold it to the hot glue gun and carefully drop a small amount of glue on your connection. You can then use pliers or tweezers to improve your connection while the glue dries. Finally test your connection with alligator clips.

Step 4: Making a Encosure

Set your component on a piece of cardboard. Apply some hot glue and secure your connection. Then hot glue another piece of cardboard on top of the previous.

Step 5: Make It Stick!

Hot glue a magnet on top of the current enclosure. test your circuit again to confirm that it works.

Step 6: Make More!

I only made one more of this great invention but you can make tons and they all will easily connect! If you enjoyed this instructable please vote for me me in the tech contest.
