make magazine has a pretty cool podcast (iTMS link)suitable for tinkerers of all ages—everything from robots to making a wallet out of tape. most of the episodes are video, some are audio or “enhanced podcasts,” and there are some pdf files too. i haven’t dowloaded and watched all of the past episodes, but some titles look interesting: how to make a USB PSP charger, a world record attempt on reading RFID tags from a distance, John Maushammer’s cvs rocket cam, Bathsheba Grossman’s geometric art, etc. There are some cool interviews and demonstrations, including iRobot’s packbot, and a walk-through of survival research labs.
