Chuck Bagg
Areas Chuck Bagg is Knowledgeable in:
Analog circuit design, power electronics design, endocrinology, EV & Hybrid automotive design, Simple workable solutions to social and political problems.
Techniques Chuck Bagg Uses:
Intuition, imagination, logic, ego, cherry-picking seemingly unrelated tidbits of information from my vast and varied experience. Bagg's Law (which I named after myself, of course) states that an illogical problem requires an illogical solution. My motto is, "If I can't fix it, it just ain't broke."

Chuck Bagg's Problem Solving Experience:
- I was working as a temp at a defense contractor. The Army had a laser device that weighed 30 pounds, was carried in a backpack, and needed a car battery to run it. My employer proposed replacing it with a 3-pound device shaped like a handgun and running on a lithium cell in the handle. I had to design a laser driver circuit that could produce a voltage-controlled current pulse of 200 Amps at 24Volts (4800W) for 200 microseconds at a 20Hz rate while drawing less than 10A from the 3V lithium cell. And it all had to fit in less than two cubic inches. I had a working board in less than 6 months and it had an overall efficiency of better than 85%. The design earned my my third patent.
- When I began work on this project, I didn't know that the agriculture industry and university research departments had been trying for over 20 years to develop a reliable cost-effective header height control for a grain harvesting combine, and that mechanical, optical, RF, and ultrasonic approaches had all failed. I solved the problem in three months with $50 worth of parts using pulse-coded audio signals at 6.4KHz with a two-inch wavelength to penetrate dense crops and measure height above the ground. I was surrounded by at least half a dozen Ph.D.'s telling me it couldn't possibly work because the combine was too noisy. Nine years later, it was still state-of-the-art and my first patent was granted on the design.
