Ep 327: A Ploopy Knob, Rube-Goldberg Book Scanner, Hard Drives And Power Grids Oscillating Out Of Control

It's Independence Day here in the USA, but if you're not a fan of fireworks and hot dogs, Elliot and Dan's rundown of the best hacks of the week is certainly something to celebrate. Rest easy, because nothing exploded, not even the pneumatic standing desk that [Matthias] tore into, nor the electroplated 3D prints that [H3NDRIK] took a blowtorch to.

We both really loved the Ploopiest knob you've ever seen, which would be even Ploopier in anodized aluminum, as well as an automatic book scanner that takes its job very seriously. We looked into the mysteries of the Smith chart, another couple of fantastic student projects out of Cornell, the pros and cons of service loops, and what happened when the lights went out in Spain last Spring. And what does Janet Jackson have against laptops anyway?
