About the Author

Thomas C. Hayes
Tom Hayes reached electronics via a circuitous route that wound through some years as a Wall Street lawyer and eventually to teaching Laboratory Electronics at Harvard, work that he has done for more than twenty-five years. He has also taught electronics for the Harvard Summer School, the Harvard Extension School, and for seventeen years in Boston University’s Department of Physics. He shares authorship of one patent. Tom designs circuits as the need for them arises in the electronics course. One such design is a versatile display, serial interface and programmer for use with the microcomputer that students build in the course.
