I have been building power supplies since I was 11 year old.  The first was when my father's friend gave me a few boxes of ham radio parts he didn't want when he moved to Florida.

I had dozens of vacuum tubes, and no way to light them up.  A trip to Radio Shack, and a few days reading up at the library later, I had a transformer plugged into the wall, and a bright tube filament at the other end.

I remember blowing up many LEDs with a 9V battery before learning about current limiting resistors, and filled my room with toxic smoke once after plugging a string of DC capacitors directly into the 115VAC outlet.

(Mom was not impressed).

I was most pleased in the '80s when I learned about DC to AC inverters, and I could take "indoor" equipment outside to play.  With a big enough stack of car batteries, you could do almost anything.

We stuck a shopvac on a 4ftx8ft sheet of plywood with a garbage bag skirt, with an inverter and battery pack on a sled, and made the coolest hovercraft in the world!

My friends and I had built a "fort" in the trees on some city-owned land with 12V lights, a full car music system with a security system based on a garage door opener IR sensor.  We just had to drag the batteries home periodically to charge them. Solar panels would have been nice back then.

In college I learned that a VIC20 could be operated directly from 12V, so we mounted one in a minivan with a portable B/W TV and built a rally computer for the 1985 SCCA POR contest.


After college, I was working at Chrysler corp. and attended an EMI  seminar with Henry Ott -  home page , and learned quite a bit about electromagnetic noise and interference that day.  All my power supply designs changed after that seminar.  There are many tips and tricks to power supply design, I've built 1V LED supplies, shrunk quarters with thousands of volts, and built a 750,000 volt pair of Tesla coils, and I'm still learning how to do it right.

I have many students come through my labs each year, and having this book on the shelf would be useful to all of us.

That's why I should win a TI "Fundamentals of Power Supply Design" book.
