OshwiPin: DIY PINS


Creation of OSHWDem mascot brooches (OSHWi, the octopus) made with felt, LEDs and conductive thread, during OSHWDem 2019.

The idea is to give an introduction to e e-textiles and soft circuit basic notions for anyone who knows a lot or a little about electronics.

We will provide a kit of materials with everything necessary for its preparation, and the BricoLabs volunteers will be on hand to help you make them, so that all the participants can take them home finished.

That way, we will help to spread the image of OSHWDem and promote open source technology to the general public.

Tips on sewing with conductive thread

  • Cut the conductive thread into small pieces, because with longer ones it becomes more entangled, among other problems (entanglements, the thread becomes untwisted, etc …) and here’s a tip, as my mother used to say: “Long thread, small seamstress ”.
  • Use a thimble: “A seamstress without a thimble, sews little and badly”. Thank you for keeping my fingertips safe, mum!
  • A needle with a big eye (because the conductive thread is thicker than standard thread), but not too big, because otherwise it doesn’t go through the holes of the snap fasteners.
  • A needle with a fine point (because big-eyed needles usually have a round tip and they don't pierce the felt easily, making it difficult to sew).
  • In thick fabrics such as felt, to avoid showing the stitches on the right side of the work, it is best to sew on the reverse and pierce only half of the fabric, keeping it tidy on the right side.
