Ed Nauman had a bad habit of leaving
his workshop at night without turning off the heater. His wife would get up in
the morning and find - to her consternation - the workshop was plenty toasty.
In the interest of keeping peace in his household, Ed decided to create a
gadget that would save the energy spent through forgetfulness. He knew he could
buy an off-the-shelf solution, but as he says, "Where's the fun in that?"
Instead, Ed turned to the world of thermostats and microcontrollers.
