Here it is--a collection of Forrest Mims's classic work from the Modern Electronics magazine! Using commonly available components and remarkable ingenuity, Forrest shows you how to build and experiment with circuits like these:
analog comparators
audio synthesizers
data loggers
fiber optic sensors
laser diode devices
MOSFET oscillators
piezoelectronics
power electronics
programmable function generators
pulse generators
radio control systems
and much, much, more!
