Whats on my workbench?     One of my favorite circuits! A Maxbotix Ultra Sonic Range Finder, ATtiny45, and a vibrating motor.  

    Comparison testing a variety of conductive threads available from ebay, etsy, and online retailers. Unfortunately, many of the the threads are not conductive and can not be used for eTextiles. I’ll start posting results next week.  

  When I receive a new ‘conductive thread’ I first test for continuity and then resistance.     Set your multimeter to the continuity setting, I prefer multimeters with an audible setting. Then place the two probes along the material to be tested. In general, if the multimeter makes a beeping sound then the material demonstrates continuity and will work […]

  This is stranded hook up wire that I purchased from eBay.   It comes pre-tinned.   A comparison of solid core to stranded wires.

    Current flows from the battery along the negative trace (black) thru a resistor and to the negative lead of the LED. The electrons jump the P-N Junction inside the lens cap emitting light and the depleted current returns to the battery along the positive trace (red). Other blog posts on LED’s LED Close Up
