This week, Editor-in-Chief Elliot Williams and Assignments Editor Kristina Panos met up over thousands of miles to discuss the hottest hacks of the past seven days. There's a whole lot of news this week, and the really good part is the the small radioactive source that went missing in Australia has been found. Phew!

Kristina is still striking out on What's That Sound, but we're sure you'll fare better. If you think you know what it is, fill out the form and you'll be entered to win a coveted Hackaday Podcast t-shirt!

Finally, we get on to the hacks with an atomic pendulum clock that's accurate enough for CERN, safecracking the rough-and-ready way, and plenty of hacks that are non-destructive to nice, old things. We'll gush over a tiny DIY adjustable wrench, drool over CNC pizza, and rock out to the sounds of a LEGO guitar/synthesizer thing.

Check out the links and as always, tell us what you think about this episode in the comments!
