I am the proprietor of Chris’s Corner, an electrical engineer with more years in the field than I want to admit. I got hooked on electronics via Ham radio back in the 70s (WD4OLP / HL5ZJJ) and graduated from Georgia Tech in 1985. I’ve worked on all sorts of electronic projects, from government radars, NASA programs, industrial controllers, and consumer products. I’ve lived in South Korea for 20 years, where I’ve established a niche manufacturing company and an engineering consultancy. During pandemic I’ve sequestered myself here in my home office and laboratory, keeping busy on engineering projects and writing technical articles in my free time.
