Sometimes running a handmade biz can get pretty pricey.
Collin Cunningham teaches you how to etch your own circuit boards using the photoengraving method.

Many an experimenter, hacker, tinkerer, & maker have heeded the call of the mighty matrix – and it’s no mystery why.
Long before the dawn of digital music, folks employed the power of the electric color organ (aka “light organ”) to add some synced visuals to their hi-fi experience.
Using the Arduino development platform you will learn how to display numbers and letters on a single 7-segment LED display.
