  Preparing for a workshop takes double the time to teach the workshop.   SHopping for the supplies.   Programing microcontrollers, packaging the tiny electronic parts, and then fitting everything into a suitcase.   Its all behind the scene, but without rigorous preparation the workshop will suffer.

  Red LEDs are electron hogs. They will always be the first to glow and even prevent other LEDs from illuminating.     When designing your circuits be sure to isolate the red LEDs from other colors otherwise you’ll have a darkwad in the final design.   read more on LEDs at wikipedia

  Sew traces with conductive thread and red or black bobbin threads to indicate the electrical polarity. Adjust the tension allowing the bobbin thread to pull thru to the fashion fabric so that the polarity is easily determined. Reverse side of the fabric clearly shows the bobbin thread. Keep bobbins wound and ready for action.

  When using conductive thread in a sewing machine choose a needle with a large eye so the thread will flow smoothly and not fray.   I use a Schmetz 90/14 embroidery needle on both my industrial machine as well as my Bernina 180.     For hand sewing conductive thread my favorite needle is a John James Chenille size […]

  I’ve been thinking the eTextile Lounge deserves a new photo, but I love this one so much!
