Another week, another Hackaday podcast, and for this one Elliot is joined by Jenny List, fresh from the BornHack hacker camp in Denmark.There’s a definite metal working flavour to this week’s picks, with new and exciting CNC techniques and a selective electroplater that can transfer bitmaps to metal. But worry not, there’s plenty more to tease the ear, with one of the nicest cyberdecks we’ve ever seen, and a bird that can store images in its song.Standout quick hacks are a synth that makes sounds from Ethernet packets, and the revelation that the original PlayStation is now old enough to need replacement motherboards. Finally we take a closer look at the huge effort that goes in to monitoring America’s high voltage power infrastructure, and some concerning privacy news from the UK.
