History and Mission of Discovercircuits.com
|From an early age, David A. Johnson, P.E., has always been passionate
about electronics. His tinkering began in his pre-teen years. For the past 40 years he has been a successful consulting electronics engineer with experience in the areas of analog & digital design, electro-optics, RF and instrument design. In 1998 he created a web site ImagineeringEzine.com to promote creativity and imagineering (a term coined by Walt Disney).
|On April 24, 2002 he launched DiscoverCircuits.com.
The site was born from the frustration produced by spending many hours searching for specific circuit designs from 100s of different website sources. Since the beginning, Discover Circuits has attracted a steadily growing stream of both unique and returning visitors. It has truly become a "one stop shop" for finding circuit schematics, components and links to other useful information.
|In the early months, the site featured
circuits designed by Dave. By May 19, 2002 the site linked to more
than 2500 carefully categorized circuits. Today it has over 45,000 links to designs by others and 4000 links to Dave's designs. New circuits and/or links are added regularly as a resource for inventors, hobbyists, engineers, scientists and students. Our goal is to help our visitors find quick solutions to electronic design requirements.
|We continually surf the net searching
for viable links to specific electronic circuits, schematics, designs or diagrams.
