Elliot and Al got together to discuss this week's projects, and you're invited! You'll hear news about replaceable batteries in the EU, along with some news about the Hacakday Op Amp Challenge winners and the start of a new contest. This week's choice hacks ranged from a Star Wars-style volumetric display, navigation using cosmic rays, measuring car speed with microphones, and a crazy 3D printing technique that will blow you away.

There's plenty more where that came from. Ever tried to land a model rocket vertically? How about building a punched card reader? The can't miss articles this week cover a thermal camera review and the unintended consequences if AM radio bites the dust.

If you want to read along, head on over to Hackaday. Be sure to leave us your thoughts in the comments.
