Radio and Electronics Brain Benders

Do you like radio and electronics? Do you like puzzles, riddles, and brain benders of all sorts? If so, here's the best of both worlds!
Over fifteen puzzles (and, just in case you need them, solutions)... Figure out the equivalent resistance of a resistor network. Find how a bit of creative wiring can let you do some interesting switching of light bulbs. And, just to add to the fun, throw in a few of those infamous word problems everyone loves so much!
Grab some scratch paper and set down for an hour or so to exercise your mind.
This book includes seventeen different puzzles and details on the solutions. And if it doesn't make you think a bit, get a refund using Amazon Kindle's return policy. That's as close to a money back guarantee as we can offer.
