  Sewing circuits with tools from three generations. Great grandmother’s silver sewing tray, father’s Fluke multimeter, and my innovative multidisciplinary mind.   Three cheers for the ancestors!  

  Yes please!    

  I didn’t solve this circuit prototype the first time.     So I’m back at it again!    

  Holiday or no holiday the workbench keeps on prototyping!    

  Way back in 2011 I used CUPro conductive paint to test different application methods for circuit boards and LEDs. Thanks to my impeccable filing system I just found the sample papers and the paint.     GOOD NEWS – the paint is still is working as a conductive trace! In fact even after three years the resistance remains the […]

  I use 3V coin cell batteries in many of my eTextile and paper computing projects. They’re small, easy to use, and effectively power multiple LEDs. In general the negative terminal is the underside, unmarked, and has a dotted textured surface. While the positive side will be marked with a + symbol. These CR2032, as with the design of most […]
