I’ve been working on the interactive eTextile flowers that I will present at the Denver Art Museum Untitled event Friday 26 April. Inside this felted stamen I inserted a Maxbotix ultrasonic range finder   This sensor will feed analog information to an ATtiny45.  If the range is within two feet then the 10mm red LEDs will illuminate. If you are […]

I don’t know about you, but I order my batteries thru eBay. easy and cheap. As soon as I get them I test a few for longevity. Stay tuned….. I’ll post when the LED goes out. The LED remained illuminated until Monday. Not as bright as I might want but still glowing. All in all – $13 USD for 100 […]

Its taken some time to set up the raspberry pi. And it was worth it!

  Lolwa Hassan Jamal made an eTextile lighthouse from conductive thread, ATtiny45 and a craft tech pressure sensor of conductive fabric and velostat. AWESOME! view on youtube By pressing on the light house door the user activates the LEDs to flicker. She made this three days after being introduced to an LED and 3V battery. I am so impressed!! I […]

On our last day we sprinted to the finish line completing our projects, setting up the final display wall and cleaning up the library. LED Hat by ____________________   Paper Corset with LEDs by _____   Hisham completed his handweaving with conductive thread and 10mm LEDs.   ______ lent her talented hands for the detail work.   The Ladies created […]

By Day 4 we were all in the creative spirit with our own projects, sharing our new techniques with each other and teaching the interested bystander on how to use conductive thread to make a basic LED circuit.  See one. Do one. Teach one. The M2’s made a glowing pillow!   While Hisham worked on needle felting and integrating Maxbotix’s […]

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 […]

Remember the first time you played with Light Emitting Diodes? Well today I have the privilege of sharing LEDs with Tasmeem! The wikipedia LED entry tells all. I would add a label for the P-N junction and note that typically the positive lead is the longer one.
