You may have noted I have occasionally referred to "one of my colleagues" in some of my posts. Unfortunately the person I most often referred to was suffering from some fairly nasty medical conditions which finally resulted in his death. I was charged by him (and later his family) to ensure his vast collection of electronics was put to some use. Alas, he has no relatives interested in electronics. You may have noted that I am quite fond of purchasing the odd bit of dead test equipment to repair. Ross was more interested in building his tools. He often needed some gadget to make something easier or more efficient. He would often make several prototypes and go to a great deal of effort to get the device "just right". His skills with his lathe and other metal-working tools in his shed were formidable. Fortunately he also kept lab notes (that I have managed to collect together) and also attached documentation to anything large enough to fit a label on. I have ended up with a large number of electronic gadgets, some of which are not entirely obvious of purpose. I plan on a post or so on each one as I get around to photographing them.
