Join Hackaday Editors Elliot Williams and Tom Nardi as they go over their picks for the best stories and hacks from the previous week. Things start off with a warning about the long-term viability of SSD backups, after which the discussion moves onto the limits of 3D printed PLA, the return of the Pebble smart watch, some unconventional aircraft, and an online KiCad schematic repository that has plenty of potential. You’ll also hear about a remarkable conference badge made from e-waste electronic shelf labels, filling 3D prints with foam, and a tiny TV powered by the ESP32. The episode wraps up with our wish for hacker-friendly repair manuals, and an interesting tale of underwater engineering from D-Day.

Wait, what? Is it time for the podcast again? Seems like only yesterday that Dan joined Elliot for the weekly rundown of the choicest hacks for the last 1/52 of a year. but here we are. We had quite a bit of news to talk about, including the winners of the Component Abuse Challenge — warning, some components were actually abused for this challenge. They’re also a trillion pages deep over at the Internet Archive, a milestone that seems worth celebrating.

As for projects, both of us kicked things off with “Right to repair”-adjacent topics, first with a washing machine that gave up its secrets with IR and then with a car that refused to let its owner fix the brakes. We heated things up with a microwave foundry capable of melting cast iron — watch your toes! — and looked at a tiny ESP32 dev board with ludicrously small components. We saw surveyors go to war, watched a Lego sorting machine go through its paces, and learned about radar by spinning up a sonar set from first principles.

Finally, we wrapped things up with another Al Williams signature “Can’t Miss Articles” section, with his deep dive into the fun hackers can have with the now-deprecated US penny, and his nostalgic look at pneumatic tube systems.

It’s a wet November evening across Western Europe, the steel-grey clouds have obscured a rare low-latitude aurora this week, and Elliot Williams is joined by Jenny List for this week’s podcast. And we’ve got a fine selection for your listening pleasure!

The 2025 Component Abuse Challenge has come to an end, so this week you’ll be hearing about a few of the entries. We’ve received an impressive number, and as always we’re bowled over by the ingenuity of Hackaday readers in pushing parts beyond their limits.

In the news is the potential discovery of a lost UNIX version in a dusty store room at the University of Utah, Version 4 of the OS, which appeared in 1973. Check out your own stores, for hidden nuggets of gold. In the hacks, we have two cameras at the opposite end of the resolution spectrum, but sharing some impressive reverse engineering. Mouse cameras and scanner cameras were both a thing a couple of decades ago, and it’s great to see people still pushing the boundaries. Then we look at the challenge of encoding Chinese text as Morse code, an online-upgraded multimeter, the art of making lenses for an LED lighting effect, and what must be the best recreation of a Star Wars light sabre we have ever seen. In quick hacks we have a bevvy of Component Abuse Challenge projects, a Minecraft server on a smart light bulb, and a long term test of smartphone battery charging techniques.

We round off with a couple of our long-form pieces, first the uncertainties about iRobot’s future and what it might mean for their ecosystem — think: cheap hackable robotics platform! — and then a look at FreeBSD as an alternative upgrade path for Windows users. It’s a path not without challenges, but the venerable OS still has plenty to give.

As always, you can listen using the links below, and we’ve laidout links to all the articles under discussion at the bottom of the page.
