If you were keeping up with Make Zine's Maker Camp this week, you'd already have built a homemade marimba, a set of tube-driven speakers with LED lights, a one-string Diddley Bow guitar, and by the end of the weekend, an LED organ. In addition to daily DIY tutorials, the Make editors also curate a series of Google Hangout lectures every Tuesday, the most recent featuring sound artist Jesse Seay. Check out the full schedule here, including next week's "field trip" to Pixar.  

The Maker Camp is a six-week Google+ based program organized by Make Media for teenage students.
