I am feeling a bit nostalgic today, so I will bother you with memories of the past – how it all got started when I was 12 years old. For more than 20 years my soldering iron (Weller, of course!), my oscilloscope, my pile of spare components, home-made PCB’s and other stuff has been stashed away in a few boxes in a dark place. Recently in a burst of nostalgia, I grabbed these boxes from the attic and started snooping around. It brought back memories of etching PCB’s in my mom’s backing dish (she hated that!), countless hours of finding the flaw in a circuit I built on a breadboard and assembler programming on home built microprocessor systems just to flash some LED’s or 7-segment displays.
