Last year’s Hackaday Superconference badge was an electronic tour de force, packing an ECP5 FPGA shoehorned into a Game Boy-like form factor and shipping with a RISC-V core installed that together gave an almost infinite badge hacking potential. It did not however run Linux, and that’s something [Greg Davill] has addressed, as he’s not only running Linux on his badge, but also a framebuffer that allows him to use the badge screen as the Linux terminal screen. Finally you can watch Linux boot on your Superconference badge itself, rather than over its serial port.
He’s achieved this by changing essentially everything: from the new VexRiscv CPU core, to new video drivers and a VGA terminal courtesy of Frank Buss, now part of the LiteVideo project. It’s not quite a fully fledged Linux powerhouse yet, but you can find it in a GitHub repository should you have a mind to try it yourself. Paging back through his Twitter feed reveals the effort he’s put into this work over the last few months, and shows that it’s been no easy task.
For those keeping score at home, this is an open hardware design, running an open CPU core, with community-designed open-source peripherals, compiled by an open-source toolchain, running an open-source operating system. And it’s simply a fantastic demo for the badge, showing off how flexible the entire system is. One of the best parts of writing for Hackaday is that our community is capable of a huge breadth of amazing pieces of work, and this is an exemplar of that energy. We can’t wait to see what Greg and any other readers tempted to try it will come up with.
If you’d like to refresh your memory over the 2019 Supercon badge, here’s our write-up at the time.
Well, this is it. The end of the decade. In a few days the 2010s will be behind us, and a lot of very smug people will start making jokes on social media about how we’re back in the “Roaring 20s” again. Only this time around there’s a lot more plastic, and drastically less bathtub gin. It’s still unclear as to how much jazz will be involved.
Around this time we always say the same thing, but once again it bears repeating: it’s been a fantastic year for Hackaday. Of course, we had our usual honor of featuring literally thousands of incredible creations from the hacking and making community. But beyond that, we also bore witness to some fascinating tech trends, moments that could legitimately be called historic, and a fair number of blunders which won’t soon be forgotten. In fact, this year we’ve covered a wider breadth of topics than ever before, and judging by the record setting numbers we’ve seen in response, it seems you’ve been just as excited to read it as we were to write it.
To close out the year, let’s take a look at a few of the most popular and interesting stories of 2019. It’s been a wild ride, and we can’t wait to do it all over again in 2020.

If you count yourself among the several hundred of our closest friends that have joined us at Supplyframe HQ for the 2019 Hackaday Superconference, then by now you’ll have your hands on one of this year’s incredible FPGA badges. It should come as no surprise that an incredible amount of time and effort went into developing and manufacturing this exceptionally unique piece of hardware; the slick gadget in your hands today took nearly an entire year to develop, and work continued on it until very literally the last possible moment.
Badge designer Jeroen Domburg (aka Sprite_TM), Hackaday staff, and a team of dedicated volunteers were still putting the final touches on these ambitious devices less than 24 hours before they were distributed to the first wave of Superconference attendees. Naturally, that’s not exactly how things were supposed to go. But when you’ve got a group of people that want to push the envelope and build something truly incredible, convincing them to actually stop working can be a challenge in itself.
In fact, development of the badge is still ongoing. Fixes and improvements are being made to the software even as you read this, and if you haven’t already, you should upgrade your badge to make sure you’ve got the latest and greatest from our international team of wizards. We all know that conference badges have an unfortunate habit of languishing on the shelf and collecting dust, but the 2019 Superconference badge was built to challenge you for longer than just one weekend. Consider yourself warned: for every Supercon badge that gets tossed in a drawer come Monday, Sprite_TM will shed a single tear.
After the break, come along as we turn back the clock and take a look at the last minute dash to get 500+ badges programmed and ready to go before the doors opened for the 2019 Hackaday Superconference.

Supercon badge hackers had to be ready to present their show-and-tell by 6 pm Sunday evening. This ruthless unmoving deadline meant every badge hack on stage represents an accomplishment in time management, and some luck, in addition to their own technical merits. But that deadline also meant a few fantastic projects lost their race against the clock. We were rooting for [Jac Goudsmit] to build an Apple I emulator as his badge expansion, but he wasn’t quite done when our badge hack ceremony began. After Supercon he went home, finished the project, and documented everything in a detailed writeup.
Our 2018 Supercon badge is built on a retro-computing theme, and the default firmware came with a BASIC interpreter as well as a Z80 emulator running CP/M. So an Apple 1 emulator should feel right home with its contemporaries. Mechanically speaking, all the parts were a tight fit on the badge expansion board given out to every attendee at Supercon. So tightly that [Jac] had to file down the two main chips in order to fit them side by side. The breadboard-like pattern of connected holes on the expansion board, intended to help ease in beginners for their badge hack soldering, proved to be an inconvenience in tightly packed arrangements such as this.
With all the work [Jac] had invested, it was heartbreaking to know he was only five minutes of soldering and 30 minutes of coding away when time ran out. Time pressure was part of the challenge faced by every Supercon badge hacker, and while we’re sad [Jac] missed the deadline for stage time we’re happy to see him finish and write it all up. We hope every badge hacker would write up their stories of frantic weekend projects. Those who do so on hackaday.io are encouraged to tag their project with “Supercon” and get them added to our list of badge hacks for everyone to admire.
At the end of Hackaday Superconference weekend, we hold a badge hacking ceremony on the main stage where anyone who has done anything with their badge is invited to come on stage and show off their work. Yes, even if it’s just a blinking LED! It was a tremendous pleasure to see not only people taking us at our word and presented blinking LEDs, but that the community in the room welcomed these inductees to hardware hacking with cheers. Before the ceremony, though, there was a lot of frantic work by badge hackers armed with soldering irons and fueled by caffeine. It’s always amazing how much people can accomplish in a single focused weekend.

In addition to great speakers and enlightening workshops at Supercon, we have an area set aside for attendees to hack on their conference badges. There is no prerequisite beyond having a badge and a willingness to get hands-on. From hardware beginners to professional embedded system developers, we welcome all skill levels!
The image above is a free-form LED light sculpture by [4C1dBurn], who had just learned to solder and this is how a new skill was put into practice. In the background is the badge hacking arena: 7 tables set up in a row with 6 seats per table. The doors opened at 9AM and almost all the seats were filled by 9:30AM. There’s a constant flow as people leave to attend a talk or workshop, and others arrive to fill the vacancy.
In our hardware hacking overview, we shared an example of an LED array controlled by badge using shift registers. Several badge hackers built on top of this idea. [X] is making a version for surface mount LEDs, and [macegr]’s variant incorporated an USB-to-serial adapter on board to reduce wire clutter. He calls it a “quality of life improvement” and we think it’s brilliant.
Any reduction in wire clutter can only help with the many glorious explosions of wires scattered about. This particular example is a work-in-progress by [carfucar] turning a badge into wireless remote for a large array of WS2812B LED strips.
Heeding our call to action in the hardware hacking overview, there are at least two efforts underway to add wireless communication capability to the badge. [Preston] is making good progress teaching a badge to talk to an AVR-IoT module. [morgan] and [Ben] are building a mesh network using ESP32s. If it gets up and running, they’ve brought a bunch of ESP32s to add more nodes to their network.
For the talks currently on stage, go to the Supercon event page and click “Livestream” in the upper right corner for the official live stream. Badge hacking will continue all through Supercon, parts of which will be visible through unofficial livestream of badge hacking from attendees like [X]’s robot [Sharon].
Hackaday Superconference is just a week away (precious few tickets remain), a celebration of all things Hackaday, which naturally includes creative projects making the most of their hardware. Every attendee gets a platform for hacking in the form of the conference badge.
To make the most of your badge hacking fun, plan ahead so you will have the extra components and the tools you need. At the most basic, bring along a serial to USB cable and a PIC programmer. These are common and if you don’t own them, ask around and you will likely be able to borrow them. Now is also the time to put in a parts order for any components you want to use but don’t have on hand!
The badge is hackable without any extras, but it’s designed for adding hardware and hacking the firmware. We’re excited to see what you can do with it. We gave an overview of this retro themed pocket computer a few days ago, today we’re inviting you to exploit its potential for your hardware hacks.
