Last week, our very own regular blog contributor Jo Hinchliffe, AKA Concretedog, was spotted on the Open Source Hardware Association (OSHWA) @oshwassociation monthly ‘show and tell’ livestream.

This Tuesday’s #HacksterCafe guest is Cody Walker, and we’re chatting about the Hacker Pager from https://Exploitee.rs (https://hackerpager.net), which sold out at #DEFCON this year!

It’s the coolest #Meshtastic device I’ve seen, with a spectrum analyzer and Wireshark integration—plus sweet LED animations. Join us & drop your questions in the chat!

Recently we've been thinking about how we share code (and other design files) for our #OpenSource projects and products.

@amcewen has written about the flaws in centralized options like Github and Gitlab, and why self-hosting isn't the answer.

Maybe we need some #CodeCommons?

Nice write-up from @concretedog about our @oshwassociation certified bike soundsystem relay setup, and how I used both @FreeCAD and @kicad to make it.

Really exciting work done by my colleague Daniel on a "water-in-salt", all-iron flow battery electrolyte. He's trying to repeat and build on some work from the University of Utah. If this works, it will be an even better approach than zinc-iodide electrolytes for low-cost, open-source flow batteries!
