It’s great to be a tech geek, DIY enthusiast, robot fancier, craft monkey, or sustainability junkie when the Maker Faire hits town. Hosted by seemingly limitless source of tech-craft and lifestyle-tinkering tips Make Magazine, the Maker Faire is one part science museum, one part craft fair, one part art show, and one part out-of-this-world. Possibly the largest festival in the world devoted solely to the guiding DIY principle (or making) the Faire attracts a broad spectrum of participants, whose only common denominator is their insistence on doing-for-themselves — and their enthusiasm for sharing their methods with the world.

A wide variety of predilections are on display: the pedal-powered carnival rides of San Francisco bike rodeo team Cyclecide, the forward-ticking 10,000 year clock being built by the Long Now Foundation, the backwards-in-time flair of the Carnivale Mechanique and the Society for Creative Anachronism, the gleeful destruction in the combot battle arena and the quiet sustainability on display at the Homegrown Village exhibit. Attendees can test drive a wooden bike or help operate a pedal-powered music stage, learn how to make tofu or how to use microcontrollers for inspired life-hacking, build a petBot, a solar-powered engine, or an aluminum can static electricity generator, or haul a bag of old clothes to the Swap-o-rama-rama and be tutored by a bevy of savvy refashion mavens in ways to spin old threads into new.

This weekend marked the fourth consecutive year the Maker Faire’s Bay Area presence, and this year saw their first expansion overseas with the Maker Faire UK in Newcastle last March, and an unaffiliated (but apparently sanctioned) festival Maker Faire Africa which will take place in Ghana this August. What makes the Maker Faire unique is that by putting the focus on DIY rather than just technology, just crafts, or just amusement, it bridges the gaps between these often very disparate fields, revealing the similar drives that makers of all stripes seem to share: curiosity, intuition, and innovation. This focus is applied to attendees as well, who are encouraged to engage in the hands-on displays, share their own knowledge, and perhaps become inspired enough to return the next year — as an exhibitor.
