This week on the big 300th episode, Hackaday’s Elliot Williams and Kristina Panos teamed up to bring you the latest news, mystery sound, and of course, a big bunch of hacks from the previous week. So basically, business as usual.

First up in the news: it’s time for the Hackaday Europe 2025 call for proposals! Do you have a tale of hardware, firmware, or software that must be shared with the Hackaday crowd? Then this is your chance to regale us with a 20- or 40-minute talk. You know we love to hear new voices, so be sure to consider proposing a talk.

On What’s That Sound, it’s a results show week. Congratulations to [Kelvin] who was one of many that correctly identified it as the Wii startup sound. Kristina will just be over here with her Pikachu64 with the light-up cheeks.

Then it’s on to the hacks and such beginning with a rather nice reverse-engineering of the PS1, which surprisingly did it with a two-sided board. Then it’s on to a smartphone home server, magic eye images in a spreadsheet, and the math behind the music of 80s. Finally, we talk about disc cameras, the hovercraft revolution, and a whole mess of keyboards.
