Sewing Circuits Kit

by Brown Dog Gadgets

Make simple wearable electronics with this fun filled STEAM and STEM kit.

Making wearable electronics and soft circuitry projects has never been easier thanks to the Sewing Circuits Kits. Using Conductive Thread and the special Crazy Circuits components you can easily sew a circuit onto any fabric. Create a shirt, bracket, or pillow in minutes using only basic sewing skills. If you can sew a button on a shirt you can make your own wearable project.

Each version of the kit comes with everything you need to start creating projects right out of the box. It includes fabric, needles, conductive thread, batteries, and electronics parts. Follow one of the many online guides or create your own project from scratch.

These kits are intended for students ages 10 and up due to the needles, batteries, and fine motor skills needed to complete this project. Coin cell batteries can be very dangerous if swallowed and appropriate caution should be used. These projects run at 3V of power and have no risk of shocking or harming people when making contact with skin. Hand wash projects only and let air dry. Do not use Conductive Thread with a sewing machine, hand stitch only.

Kit Includes:

  • 5 Batteries
  • 4 Jumbo Sewable LEDs (Red, Blue, Green, and White)
  • 2 Sewable Battery Holders
  • 2 Needles
  • 2 Threading Tools
  • 2 Button Snaps
  • 1 Roll of Conductive Thread (16 feet)
