We’re back from this weekend’s Maker Faire, the third-annual event in San Mateo, California . Our friends at Make continue to up the ante, bringing DIYers from far and wide to show off their projects at the ultimate geek county fair.

Check out the gallery below to see just a handful of the amazing stuff on display this weekend, from the iPhone-controlled watering can to the hacked Guitar Hero controllers that serve as—gasp!—real instruments. PopSci podcaster Chuck Cage also threw together the great Maker Faire highlight reel below.

If you missed the Faire this weekend, never fear: the circus rolls into Austin, Texas later this year.
