Electronics kits

At Maker Faire, taking place this weekend at the San Mateo County Events Center in San Mateo, Calif., builders of all sorts can find inspiration and innovation, exploring new ways to build and exchange ideas, creating exciting projects and DIY masterpieces.

From fire to fibers, Maker Faire brings together people who think big and want to see their dreams come to life. It's art and science all in one.

Here, first-timers learn to soldier circuits and build LED-based games that beep and blink.
