Summary

Ninjas create a felt badge that lights up.

Participants are not restricted to making badges - other ideas could be masks, bracelets, headbands, a simple patch, felt animals/characters or anything else you can think of. The project could even be implemented directly into items of old clothing. Possibilities for a collaborative project include a blanket or throw, curtain, wall hanging, tablecloth, cushion cover, etc.


What's Covered

  • Introduction to circuit components and concepts of + and -
  • Making a simple LED circuit
  • How a switch works and how to use one in a circuit
  • Using conductive thread and sewable components to make a wearable circuit
  • Basic sewing skills
  • Adding multiple LEDs to a circuit
  • How to make a wearable circuit that’s split into detachable components

Materials Required

The expected cost for a group of 10 participants is approx €50 (excl online delivery charges). Note that the battery holders (approx €2 each) contribute significantly to the cost per child. It is possible for Ninjas to collaborate on a group project that requires only one battery & battery holder - see the last card in the series for how to modify the basic wearable circuit to allow this.

  • CR2032 3V coin cell batteries
  • Sewable CR2032 coin cell battery holders
  • Conductive thread
  • Regular LEDs
  • Optional: sewable LEDs
  • Optional: sewable switches
  • Craft felt (or any available fabric e.g. cutoffs/scraps, old clothes, etc)
  • Embroidery needles
  • Scissors
  • Badge pins/safety pins
  • Embroidery thread/plain cotton thread and/or glue

Additional materials that may be useful:

  • Needle threader - strongly recommended as the conductive thread frays very easily
  • Elastic (for making headbands/bracelets/etc as an alternative to badges)
  • Crocodile clips
  • Round-nosed pliers
  • Electrical tape or masking tape
