This year’s Maker Faire Bay Area saw Google Android bots (like the smartphone-headed biped above), stolid industrial robots creating crazy art (à la Paint-Bot from WALL-E), and legions of DIY robots, from Mars rovers to bartenders to fierce combatants. See more great robots at Maker Faire in Detroit and New York this summer. makerfaire.com

Build an aquarium whose gentle curtain of recirculating water sets the stage for an ever-changing jellyfish ballet. Then wire up a lightweight, portable sign that instantly displays anything you type in big, bright LED letters. Finally, turn back the clock and make the limestone-based spotlight that was state-of-the-art pre-Edison incandescent lighting.
