Ep 187: The Sound of Gleeful Gerbils, The Song of the Hard Drive, and a Lipstick Pickup Lullaby

This week, Editor-in-Chief Elliot Williams and Assignments Editor Kristina Panos gushed about NASA's live obliteration of minor planet Dimorphos using a probe outfitted with a camera. Spoiler alert: the probe reaches its rock-dappled rocky target just fine, and the final transmitted image has a decidedly human tinge. Kristina brought the mystery sound again this week, much to Elliot's sonic delight. Did he get it? Did he figure it out? Well, maybe. The important thing is one of you is bound to get it, so budding Neos need only enter their guess and their email address on the extremely official What's That Sound? entry form. We kick off the hacks with a really neat 3D printed linkage that acts as an elevator for a marble run, and then we discuss a mid-century hack that helps you decide whether it's time to emerge from the fallout shelter using the contents of your typical 1950s pockets. We spent a few minutes comparing our recent radiation exposure levels  -- Kristina wins with about a dozen x-rays so far this year, but no full-body CT scans. Then we talk guitars for a bit, remember a forgotten CPU from TI, and spend a few cycles talking about a tone-wheel organ that sounds like a chorus of gleeful gerbils. Finally, we talk toner transfer for 3D prints, argue in defense of small teams versus large committees, and get all tangled up in cursive.
