Hackaday Podcast Episode 291: Walking in Space, Lead in the Earth, and Atoms under the DIY Microscope | usagoldmines.com

What have you missed on Hackaday this week? Elliot Williams and Al Williams compare notes on their favorites from the week, and you are invited. The guys may have said too much about the Supercon badge this year — listen in for a few hints about what it will be about.

For hacks, you’ll hear about scanning tunneling microscopes, power management for small Linux systems, and lots of inertial measurement units. The guys talked about a few impossible hacks for consumer electronics, from hacking a laptop, to custom cell phones.

Of course, there are plenty more long-form articles of the week, including a brief history of what can go wrong on a spacewalk and how to get the lead out (of the ground). Don’t forget to take a stab at the What’s That Sound competition and maybe score a sweet Hackaday Podcast T-shirt.
