Tinkering Tool Kit: Clothespin Circuits

I’m so excited to welcome a guest poster today, Irina of Natural Math.  She’s going to show you a great project that can be added to any tinkering station.  These Clothespin Circuits are perfect add-ons to make your next art project shine :)  This post contains affiliate links.

Take it away Irina!

Building Circuits

I’ve been fascinated by electrical circuits since I have been a kid. I have definitely fallen in love in them while designing electricity workshops for a local Science Centre. One of my favorite activities is paper circuits. From time to time I try to share my passion with others and organize local workshops. This workshop was very special. It was meant to be an evening event for grown-ups and ended up being a very creative family gathering. One moment we were doing paper-circuits

and the next moment clothespin circuits were born:

I was impressed and decide to explore this awesome creation with my kids. We have decided to build a rocket.

Clothespin Circuits Supplies Needed

  • a 3V coin battery {affiliate}
  • a LED {affiliate}
  • a clothespin {affiliate}
  • two pieces of stripped wires
  • decorative materials (a pin, colored paper, markers, scissors and glue)

SAFETY NOTE: This activity should be done under adult supervision, coin batteries can seriously injure your child, if swallowed!

Construct a Basic Clothespin Circuit

Take two pieces of wires. Wrap each of the wires around the legs of the LED. Carefully wrap the rest of the wires around the legs of the clothespin, making sure they do not touch the middle metallic part and each other.

The ends should be located on the inner side where the battery will be. Open the clothespin and put the battery inside the clamp section of the clothespin. If the LED does not light up, reverse the position of the battery.

Decorating Your Clothespin Circuit

Create the night sky and the rocket. Use a pin to make two holes for the legs of the LED.

Put the legs of the LED though the holes. Wrap the wires separately around each of the legs of the clothespin and place the battery into the clothespin. Tadaaa. The LED should now light up. If not, reverse the battery and check the wiring.

You can light up anything with these useful clothespin circuit LED's. They're a perfect addition to your tinkering tool kit.
