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 […]

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 […]

If you’ve ever had the good fortune of entering The Gas Station you know that my workbench is 20 feet long. This space is always a flow of projects, but this morning I noticed it was magnificently mashedup with materials. paints, solder, silk organza, great grandmothers silver sewing tray, conductive paint, Maxbotix and of course GLITTER!  Why the glitter?  I […]

I use a lot of expensive thread. I waste even more. In this picture there are five kinds of conductive thread. You can identify the stainless steel thread because of the whiskers. Those pesky short circuit makers! I keep a scrap box of tangles, tails and tatters. When sewing small repairs and adding hardware to and electrical trace I use […]
