Hackaday editors Mike Szczys and Elliot Williams discuss the latest hacks from around the Internet. 3D-Printed linear rails don’t sound like a recipe for a functional CNC machine but there was one this week that really surprised us. We were delighted by the procedurally generated music from a $0.03 microcontroller inside of an RCA plug (the clever flexible PCB may be the coolest part of that one). There’s an interesting trick to reverse engineering Bluetooth comms of Android apps by running in a VM and echoing to WireShark. And we look at what the buzz is all about with genetically engineered mosquito experiments taking place down in the Florida Keys.

Greetings from sunny Catalunya, where our viral state of emergency ends tomorrow, May 9. Woohoo!
See Colin Furze’s YouTube channel for all your stainless steel umbrella requirements.

Greets right back from sunny, but probably not quite as sunny, Southern Germany. :) Congrats on the end of state of emergency.
Colin is a madman. His steel/concrete backyard bunker is the place to be!
Still no news on that rocket debris. Hoping for the best.
When we recorded the podcast, I had forgotten that the last Long March landed in Cote d’Ivoire and flattened a few houses (with no human casualties, fortunately).
Colin is a madman? I refer you to a quote from on of our best known Catalans, Salvador Dalí, who was born and is interred about 500m from here. In two different directions :-)
‘The only difference between me and a madman is that I am not mad.’
I think that sums Colin up pretty well too.
Rocket seems to have landed in the water. Everyone can put away their steel umbrellas and get back to fabricating ultra-magnet shoes.
Not to give too much away, but we got some awesome answers for the first ever audio challenge.
Gotta think up something clever for the next one!
Pretty sure I know what that sound is, and we’ve covered a very curious hacker doing restorations on them. Some very cool retro tech.
