Jack passed away May 20, 2018 after a long battle with cancer. His Instructables site will be kept active and questions will be answered by our son-in-law, Terry Pilling. Most of Jack's instructables are tutorials for Atmel microcontrollers, Arduino, or Raspberrypi. He tried to show concepts that you can use in your own programs by creating simple programs and circuits to illustrate the idea.
