Scrappy Circuits is an innovative and scrappy way to learn about electrical circuits for around $1 per person.

Teachers can build class sets that kids can easily take home for around $20.

Step 1:

• Gather 11 binder clips (usually sold as a pack of 12) and 1 LED tealight (usually 2 for a dollar at the Dollar Store).
• Gather a few other household items (cardboard, 2 paper clips, aluminium foil, glue, and a marker)

Step 2:

• Make your five Core Bricks (Battery Brick, LED Brick, Binder Clip Switch, Pressure Switch, and Dial Switch)

Step 3:

• Experiment! Connect your Core Bricks (with alligator clips or your own Scrappy Clips) and find different ways to make the LED light up.

Step 4:

• More! Build some of the Other Bricks and design new circuits and create some amazing inventions.

Step 5:

• Share! Send some pictures to info@scrappycircuits.com or post them on www.instructables.com.

For each Scrappy Circuit set you are going to need only the following:

• one LED tealight (2-packs can easily be found at the dollar store)
• 11 small binder clips (It's easiest to buy a 12 pack)
• 2 paper clips
