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 […]

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.  

  I wasn’t allowed to disembark in Bahrain, however I could stand inside the airplane door and breath in the fresh moist night air. A welcome treat after being inside airplanes for 20 hours.  

Years ago I purchased a cone of 234/34 4 ply conductive thread with a resistance of 15 ohms/foot. As you can see in the photo – Sheildex labels it as 235/34. They explained that this number change is because the thread is wound on a one pound cone. It is great thread that I have used for teaching as well […]
