Hackaday editors Elliot Williams and Mike Szczys are joined by contributing editor Jenny List to talk about her adventure at Born Hack last week. We also discuss the many capacitor values that go into regen receivers, the quest for a Raspberry Pi handheld that includes a slide-out keyboard, and how capacitive touch might make mice (mouses?) and touchpads better. There’s a deep dive into 3D printer bed leveling, a junk-box metal detector build, and an ambisonic microphone which can listen any-which-way.
Take a look at the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!

Quick Hacks:
- Elliot’s Picks
- Mike’s Picks:
The biggest advantage to having a sensor probe the bed is if you have a warped print bed like mine you can have the firmware automatically compensate for it.
The other advantage is using different bed maps for different temps. My print bed is crap and it has a much greater curve at 80C vs 50C
