By Day 3 the eTextile and paper computing participants were well on their way to creating their own projects.  In the morning I introduced the entire group to the ATtiny45 micro-controllers as a ways to activate the LEDs to blink and fade.  While some chose to stick with basic LED circuits with textile or paper embellishments at least half the group […]

On Day 2 the challenge began with making a circuit using 5 LEDs. Participants quickly learned that multiple colors of LEDs compete for power.  Red LEDs dominate all other colors, but occasionally other colors can work together.  To be on the safe side, they began making multiple circuits to separate the colors. Hand sewn and embroidered multi-colored Star overlays by […]

The first day we were together in the library space at Mathaf we created basic LED circuits using Bare Conductive Paint, copper tape and conductive thread. Basic LED Circuit   Thru this simple exercise everyone learned that copper tape is a fast, easy and forgiving electrical conduit. That conductive paint is fun and organic but takes time to dry before […]

1386 beautiful light emitting diodes! wrapped in luscious pink bubble wrap.  As you may remember from my 8 February 2013 post I love pink bubble wrap so much a friend gave me a bag full! best gift ever ever!

Charged electrons flow from the power source along the negative trace (green) thru a resistor to the cathode. Like excited lemmings they jump the P-N junction emitting light. Finally, the spent electrons slide along the positive trace (red) to get charged up at the battery.         KEY battery is black negative trace is green resistor is blue […]

  Are you ready for this year’s Valentine’s Day project? I bet you’ve been waiting all year for this PUNCHY interactive Instructable! Beware tho – eTextile Love Hurts! Unlike last years STABBY Valentine this time – you will have to sew with poky pricky needles. Will you make a badge for your coat or a pillow for your love? Maybe […]
