I'm a retired optometrist, who likes to dabble in just about anything. As a lifetime sufferer of ADD, I relish new challenges to keep me interested and focused. Love to gadgeteer tools and devices. Hobbies include electrical design, electronics, welding, machining, building recumbent bicycles, fishing, inventing, and prototyping projects. Am, currently, working to integrate GPS and boomerangs, so I can find the ones that don't come back.
