This week, Jonathan Bennett and Aaron Newcomb chat with Simon Phipps and Stefano Maffulli about Open Source AI. Why did we need a new definition? Has it been controversial? And why did OSI step into this particular conversation?

Hackaday Europe 2025 Tickets On Sale, And CFP Extended Until Friday
We’re opening up shop for Hackaday Europe, so get your tickets now! We’ve managed to get the ticket price down a bit this year, so you can join in all the fun for $145. And if you’re reading this right now, snap up one of the $75 early bird tickets as fast as you can.
Hackaday Europe is going down again in Berlin this year, on March 15th and 16th at MotionLab. It’s going to be a day and a half of presentations, lightning talks, badge hacking, workshops, and more. This is where Hackaday hangs out in person, and it’s honestly just a great time – if your idea of a great time is trading favorite PCB design tricks, crafting crufty code, and generally trading tales of hardware derring-do.
In short, it’s the best of Hackaday, live and in person. Throughout the weekend, all the meals are catered, we’ve got live music at night, and the soldering irons will be warmed up for you. It’s going to be great!
If you’re in town on Friday the 14th, we’ll be meeting up in the evening to get together over some pre-event food and drink, sponsored by Crowd Supply. It’s a nice opportunity to break the ice, get to know the people you’re going to be spending the next 48 hours with, and just mingle without missing that great talk or wonderful workshop.

Raspberry Pi Hack Chat With Eben Upton
Join us on Wednesday, January 15 at noon Pacific for the Raspberry Pi Hack Chat with Eben Upton!
The Hack Chat has been on an extended hiatus, but we’re back for 2025 and coming strong out of the gate! We’ve been trying to get Raspberry Pi co-founder and CEO Eben Upton on the chat for a while, but there was that whole thing of taking the company public that probably distracted him a wee bit. That’s fine though, because we know he loves getting in the trenches with the hacker community and talking about the things we all love to talk about. It’s not often that you get a chance for a one-on-one like this, so make sure you join us with all your Pi-related questions.
Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, January 15 at 12:00 PM Pacific time. If time zones have you tied up, we have a handy time zone converter.

Keebin’ With Kristina: The One With The Holey And Wholly Expensive Keyboard
However, [jwr] was not completely satisfied and decided to make a custom set of keycaps. The idea was to create ‘caps without the “annoyingly abrasive texture of PBT”, that are larger than average for larger-than-average fingers. Finally, [jwr] wanted the Function row to tower over the number row a little, so these have a taller profile.
So, what are they made of? The look kind rubbery, don’t they? They are cast of pigmented polyurethane resin. First, [jwr] designed five molds in Fusion360, one for each row. Then it was time to machine master molds via CNC in foam tooling board. These were filled with silicone along with 3D-printed inserts, which produced silicone molds for casting keycaps four at a time in resin.

Hackaday Links: January 12, 2025
The big news story of the week of course has been the wildfires in California, which as of Saturday have burned over 30,000 acres, destroyed 12,000 structures, caused 150,000 people to evacuate, and killed eleven people. Actually, calling them wildfires underplays the situation a bit because there are places where they’ve clearly become firestorms, burning intensely enough to create their own winds, consuming everything in their path in a horrific positive feedback loop. We’ve even seen fire tornados caught on video. We’ve got quite a few connections to the affected area, both personally and professionally, not least of which are all our Supplyframe colleagues in Pasadena, who are under immediate threat from the Eaton fire. We don’t know many details yet, but we’ve heard that some have lost homes. We’ve also got friends at the Jet Propulsion Labs, which closed a few days ago to all but emergency personnel. The fire doesn’t seem to have made it down the mountain yet, but it’s very close as of Saturday noon.
Retrotechtacular: The 1951 Telephone Selector
Telephone systems predate the use of cheap computers and electronic switches. Yesterday’s phone system used lots of stepping relays in a box known as a “selector.” If you worked for the phone company around 1951, you might have seen the Bell System training film shown below that covers 197 selectors.
The relays are not all the normal ones we think of today. There are slow release relays and vertical shafts that are held by a “dog.” The shaft moves to match the customer’s rotary dial input.

In Praise Of Simple Projects
Hackaday was at Chaos Communication Congress last week, and it’s one of those big hacker events that leaves you with so much to think about that I’m still processing it. Just for scope, the 38th CCC is a hacker event with about 15,000 attendees from all around Europe, and many from even further. If I were to characterize the crowd on a hardware-software affinity scale, I would say that it skews heavily toward the software side of the hacker spectrum.
What never ceases to amaze me is that there are a couple of zones that are centered on simple beginner soldering and other PCB art projects that are completely full 20 hours of the day. I always makes me wonder how it is possible to have this many hackers who haven’t picked up a soldering iron. Where do all these first-timers come from? I think I’m in a Hackaday bubble where not only does everyone solder at least three times a day, some of us do it with home-made reflow ovens or expensive microscopes.
But what this also means is that there’s tremendous reach for interesting, inviting, and otherwise cool beginner hardware projects. Hands-on learning is incredibly addictive, and the audience for beginner projects is probably ten times larger than that for intermediate or advanced builds. Having watched my own son putting together one of these kits, I understand the impact they can have personally, but it’s worth noting that the guy next to him was certainly in his mid-30s, and the girl across the way was even a few years younger than my son.
So let’s see some cool beginner projects! We’d love to feature more projects that could lure future hackers to the solder-smoky side.
