I'm Jim. I used to be a wrench head back in the day (1970s/1980s). Yes, I am old. Got into electronics and computers for 40 years and had a nice career. Now, as I prepare to retire, I'm back wrenching. Well, more diagnosing than wrenching. I'll let others do the heavy work. I'm very comfortable with a scope in an electronics lab. Looking to build some solid experience under the hood.
