  Preparing for a workshop takes double the time to teach the workshop.   SHopping for the supplies.   Programing microcontrollers, packaging the tiny electronic parts, and then fitting everything into a suitcase.   Its all behind the scene, but without rigorous preparation the workshop will suffer.

  Red LEDs are electron hogs. They will always be the first to glow and even prevent other LEDs from illuminating.     When designing your circuits be sure to isolate the red LEDs from other colors otherwise you’ll have a darkwad in the final design.   read more on LEDs at wikipedia

  Analog temperature sensor TMP36 from Adafruit for $2.00 USD.     I’m working on a new project implementing the TMP36 with the ATtiny45. Please stay tuned….  

  I’ve wound off 20 yard bobbins of Mitsifuji conductive thread.     This thread is 9.5 ohms/foot and can be used as the top thread in a home sewing machine. Unfortunately, this thread is no longer manufactured.
