The Blackberry Keyboard: How An Open-Source Ecosystem Sprouts

June 4, 2025 by Arya Voronova 43 Comments

What could happen when you open-source a hardware project?

No, seriously. I hold a fair few radical opinions – one is that projects should be open-source to the highest extent possible. I’ve seen this make miracles happen, make hackerdom stronger, and nourish our communities. I think we should be publishing all the projects, even if incomplete, as much as your opsec allows. I would make ritual sacrifices if they resulted in more KiCad projects getting published, and some days I even believe that gently bullying people into open-sourcing their projects can be justified. My ideal universe is one where companies are unable to restrict schematics from people getting their hardware, no human should ever hold an electronics black box, by force if necessary.

Why such a strong bias? I’ve seen this world change for the better with each open-source project, and worse with closed-source ones, it’s pretty simple for me. Trust me here – let me tell you a story of how a couple reverse-engineering efforts and a series of open-source PCBs have grown a tree of an ecosystem.

The Rogue Emperor, And What To Do About Them

November 8, 2024 by Jenny List 134 Comments

The chances are if you know someone who is a former Apple employee, you’ll have heard their Steve Jobs anecdote, and that it was rather unflattering to the Apple co-founder. I’ve certainly heard a few myself, and quick web search will reveal plenty more. There are enough of them that it’s very easy to conclude the guy was not a very pleasant person at all.

At the same time, he was a person whose public persona transcended reality, and his fan base treated him with an almost Messianic awe. For them everything he touched turned to gold, every new feature on an Apple product was his personal invention, every one of his actions even the not-so-clever ones were evidence of his genius, and anyone who hadn’t drunk the Apple Kool-Aid was anathema. You’ll still see echoes of this today in Apple fanboys, even though the shine on the company is perhaps now a little tarnished.

It’s easy to spot parallels to this story in some of today’s tech moguls who have gathered similar devotion, but it’s a phenomenon by no means limited to tech founders. Anywhere there is an organisation or group that is centred around an individual, from the smallest organisation upwards, it’s possible for it to enter an almost cult-like state in which the leader both accumulates too much power, and loses track of some of the responsibilities which go with it. If it’s a tech company or a bowls club we can shrug our shoulders and move to something else, but when it occurs in an open source project and a benevolent dictator figure goes rogue it has landed directly on our own doorstep as the open-source community. It’s happened several times that I can immediately think of and there are doubtless more cases I am unaware of, and every time I am left feeling that our community lacks an adequate mechanism to come through it unscathed.

“Cheap Yellow Display” Builds Community Through Hardware

October 28, 2023 by Dan Maloney 29 Comments

For the most part, Hackaday is all about hardware hacking projects. Sometimes, though, the real hack in a project isn’t building hardware, but rather building a community around the hardware.

Case in point: [Brian Lough]’s latest project, which he dubs “CYD,” for the “cheap yellow display” that it’s based on; which is a lot easier to remember than its official designation, ESP32-2432S028R. Whatever you call it, this board is better than it sounds, with an ESP32 with WiFi, Bluetooth, a 320×480 resistive touch screen, and niceties like USB and an SD card socket — all on aforementioned yellow PCB. The good news is that you can get this thing for about $15 on Ali Express. The bad news is that, as is often the case with hardware from the Big Rock Candy Mountain, the only documentation available comes from a website we wouldn’t touch with a ten-foot pole.

To fix this problem, [Brian] started what he hopes will be a collaborative effort to build a knowledge base for the CYD, to encourage people to put these little gems to work. He has already kick-started that with a ton of quality documentation, including setup and configuration instructions, tips and gotchas, and some sample projects that put the CYD’s capabilities to the test. It’s all on GitHub and there’s already at least one pull request; hopefully that’ll grow once the word gets out.

Honestly, these look like fantastic little boards that are a heck of a bargain. We’re thinking about picking up a few of these while they last, and maybe even getting in on the action in this nascent community. And hats off to [Brian] for getting this effort going.

Do You SpaceAPI?

June 18, 2021 by Jenny List 8 Comments

Here at Hackaday we’re privileged to be part of a global community of hackers, makers, technology enthusiasts and creative people whose collective works make our daily news feeds such a fascinating read. We encounter you all directly in the physical world rather the virtual one at the many events across the community, or at the various hackerspaces we visit on our travels. But how can we keep track of the world of hackerspaces when there are so many? Maybe SpaceAPI might hold the answer.

A Case For Project Part Numbers

December 2, 2020 by Sonya Vasquez 32 Comments

Even when we share the design files for open source hardware, the step between digital files and a real-world mechatronics widget is still a big one. That’s why I set off on a personal vendetta to find ways to make that transfer step easier for newcomers to an open source mechantronics project.

Today, I want to spill the beans on one of these finds: part numbers, and showcase how they can help you share your project in a way that helps other reproduce it. Think of part numbers as being like version numbers for software, but on real objects.

I’ll showcase an example of putting part numbers to work on one of my projects, and then I’ll finish off by showing just how part numbers offer some powerful community-building aspects to your project.

A Tale Told with Jubilee

To give this idea some teeth, I put it to work on Jubilee, my open source toolchanging machine. Between October 2019 to November 2020, we’ve slowly grown the number of folks building Jubilees in the world from 1 to more than 50 chatting it up on the Discord server.

Get Over Your Fears

October 24, 2020 by Elliot Williams 23 Comments

Some projects are just too complex, that’s for sure. But I’d be willing to bet that some things you think are too difficult actually aren’t, and it may be that all you need to get over your personal hurdle is a good demonstration. Here come three cases in point.

I was looking at the new Raspberry Pi Compute Module last weekend. They have a whole bunch of high-speed traces: things like Gigabit Ethernet, HDMI, and those crazy-fast SDI serial camera interfaces. I have no experience in high-speed design and layout at all, and frankly it gives me the willies. But the Raspberries also shipped me an IO demo board, and concomitant KiCAD design files, with the review board. Looking at it, they were just wires — maybe pairwise length-matched and impedance controlled — but also just wires. Opening up the KiCAD board file and clicking on the traces just like I do with my own designs, I’m a lot less scared. That was a revelation for me.

In a great writeup of his experience building ten different Linux single-board-computers from scratch, Jay Carlson had a similar effect on me. I would never have considered breaking out the hotplate for some CPU-and-DRAM action, and I’ve never had to lay out a PCB with a high density BGA chip before either. I’m not quite into Dunning-Kruger territory yet; I still have a healthy respect for the layout intricacies in fanning out a tight BGA CPU into a DRAM. But Jay’s frank assessments of what is easy and what is hard make it all seem within the realm of the doable.

As Mike and I were talking on the podcast about Jay’s work, Mike came clean about his fear of BGAs. I’ve done enough reflow-plate soldering, with parts that have a lead pitch that’s a factor of two finer than the 0.8 mm pitch BGAs in question, so it doesn’t seem implausible to me. And I’m 100% sure Mike could pull it off too, but he is in need of a BGA guru. Any good hobbyist videos out there?

Being a nerdy type, I’m much more focused on the knowledge and the inspiration, but maybe the courage is equally important — at least I think I undervalue it. I don’t need to lay out HDMI lines, or build a from-scratch Linux box, but I am no longer afraid that I couldn’t, and that’s because I’ve seen detailed examples of fellow hackers who’ve done the same. I might not get it right on the first shot, but I’m not afraid to try, and I wouldn’t have said the same before looking over other folks’ shoulders. Forza e corragio!
