It’s crunch time at California’s San Mateo Event Center, where crews are busily assembling rocket ships, singing Tesla coils and animatronic giraffes and dragons in preparation for the 2010 Bay Area Maker Faire, taking place this weekend.

Returning for its fifth year, Maker Faire, if you’ve not had the pleasure, could be described as 50 percent science fair, 50 percent county fair and 50 percent Burning Man reunion. And if that doesn’t seem to add up, you’re right — it’s sensory overload, a hands-on, warranty-voiding explosion of futuristic technology, down-to-earth crafts and nine dollar pulled pork sandwiches.

If you’re planning on attending, hit up their web site for all the information on tickets and hours, recommendations for parking or — perhaps most importantly — public transit options. The event has been growing every year, even disrupting traffic on nearby U.S. Route 101, so you’ll want to set out early or research alternative options. We’ll be posting goings-on from the event as it unfolds, connectivity permitting.
