Hackaday Belgrade 2018

Some technology conferences hand you a lanyard, a tote bag, and a pen that stops working before lunch. Hackaday Belgrade 2018 took a more gloriously unreasonable approach: it gave attendees a tiny retro computer to wear around their necks. That detail alone explains why this event still has a special place in hardware hacking lore.

Held in Belgrade, Serbia, on May 26, 2018, Hackaday Belgrade 2018 was not a typical tech meetup with beige slides and suspiciously dry pastries. It was a full-day celebration of hardware creation, open engineering, creative electronics, badge hacking, demos, workshops, music, and the sort of delightful technical chaos that happens when hundreds of curious builders are placed in the same room with solder, code, LEDs, and ideas.

The event brought together engineers, artists, embedded developers, open-source advocates, researchers, retro-computing fans, PCB designers, and people who simply enjoy making machines do things they were never politely asked to do. It combined serious technical depth with playful experimentation, making it one of the most memorable Hackaday gatherings in Europe.

What Made Hackaday Belgrade 2018 Special?

Hackaday has always had a particular flavor. It is less “look at our polished product roadmap” and more “look at this weird thing I built at 2 a.m., and yes, it runs Doom if you stare at it long enough.” Hackaday Belgrade 2018 leaned heavily into that culture. The schedule included talks, workshops, a hacker village, project demos, badge hacking, lightning presentations, live music, and social events before and after the conference.

The event was designed around participation, not passive observation. Attendees were not just viewers sitting quietly in rows. They were expected to build, modify, test, ask questions, swap ideas, and probably make a few microcontrollers regret their life choices. That hands-on spirit is exactly why the conference is remembered not only for its speakers but for its atmosphere.

The Famous Hackaday Belgrade 2018 Badge

The centerpiece of Hackaday Belgrade 2018 was the custom hardware badge. Calling it a “badge” feels almost unfair, the way calling a grand piano a “noise table” would be technically possible but spiritually wrong. This was a battery-powered, stand-alone retro computer inspired by 1980s personal machines, built small enough to wear but powerful enough to hack.

The badge featured a 55-key keyboard, a 320-by-240 RGB TFT LCD screen, audio output with a speaker, external flash storage, and a Microchip PIC32MX370F512H microcontroller. It ran a customized BASIC interpreter and even supported retro-computing experiments such as Z80 emulation and CP/M-related exploration. In other words, it was not just conference swag. It was a project platform.

A Badge Built by Hardware Legends

The hardware was led by Voja Antonic, a respected name in computing and electronics circles, while the software was led by Jaromir Sukuba. Together, they created a badge that felt like a love letter to early personal computing. The design had clever physical details, including rotated keyboard buttons that were not merely decorative but part of a compact mechanical layout. That is the sort of engineering decision that makes hardware people nod slowly and whisper, “That’s annoyingly elegant.”

For many attendees, the badge became the event’s social engine. It gave everyone a shared object to explore. You could program it, modify it, show off a graphical demo, make music, use the keyboard, poke at the firmware, or simply enjoy the sound of hundreds of clicky buttons filling the room like a tiny mechanical rainstorm.

Talks That Covered the Weird, Useful, and Wonderful

The Hackaday Belgrade 2018 schedule reflected the range of the Hackaday community. It was not limited to one narrow field. Instead, the talks moved across wearable electronics, biological research, acoustic levitation, drone-assisted sensor networks, PCB design, Raspberry Pi peripheral tricks, robotic sculpture, FPGA development, music circuits, and retro microcomputing.

Rachel Wong delivered a keynote that blended wearable electronics with stem cell research, showing how creativity can connect fashion, biology, and future medical technology. It was a perfect example of the event’s broad technical personality: one foot in the lab, one foot in the workshop, and both hands somewhere near a soldering iron.

Voja Antonic and Jaromir Sukuba discussed the process of building the Hackaday Belgrade badge itself, giving attendees a behind-the-scenes look at how custom electronics are conceived, designed, manufactured, and brought to life under tight deadlines. For anyone who has ever ordered a PCB and then refreshed the shipping page 47 times, this talk likely felt deeply personal.

Hardware Creation Beyond the Usual Boundaries

Other sessions explored the creative and practical sides of engineering. Vanessa Julia Carpenter examined meaningful hardware design through prototypes that focused on experience, identity, and connection rather than pure function. Kaspar Emanuel discussed designing PCBs with code, a topic especially appealing to people who look at a circuit board and think, “This needs more loops.”

Matt Evans presented fast peripheral control techniques using Raspberry Pi hardware in ways that moved beyond traditional bit banging. Sophi Kravitz talked about building blimps, which are like drones with less personal-injury energy and more balloon-based dignity. Asier Marzo demonstrated acoustic levitation, using sound to manipulate small particles and droplets without physical contact.

Luka Mustafa shared work on drone-assisted IoT sensor network deployment and LoRaWAN coverage mapping, including conservation-related applications. Tsvetan Usunov discussed improving an industrial soldering robot using open hardware tools. Marcel van Kervinck presented a TTL microcomputer built without a microprocessor, a project that sounds like a dare and somehow became a computer.

Elliot Williams brought in the musical side of digital electronics with logic noise, showing how simple chips can become instruments of charming electronic misbehavior. Aleksandar Zivanovic explored early interactive robotic sculptures, connecting computing history with art and human interaction.

Workshops: Where Theory Got Its Hands Dirty

Hackaday Belgrade 2018 also included hands-on workshops, and these were not filler sessions designed to keep people busy between coffee breaks. They were deeply aligned with the event’s maker-first identity.

The PCB art workshop, led by Brian Benchoff, explored how printed circuit boards can become visual objects as well as functional devices. This is a concept Hackaday readers understand well: a board can blink, compute, and still look good enough to make your desk feel underdressed.

The Interactive Poetic Glove workshop, led by Lavoslava Benčić, introduced participants to e-textiles, conductive materials, fabric-based sensors, and wearable sound interaction. It demonstrated that electronics do not always have to live inside black plastic boxes. Sometimes they belong in fabric, on the body, and in performances that make traditional circuit design look slightly stiff.

The FPGA Development 101 workshop, led by Miodrag Milanovic, gave attendees an introduction to FPGA tools and Verilog. For software developers used to telling processors what to do, FPGA development can feel like discovering that the furniture in your house is negotiable. Instead of simply writing instructions, you describe hardware behavior itself.

The Hacker Village Energy

The hacker village was where Hackaday Belgrade 2018 truly shifted from conference to community laboratory. After the talks, tables filled with projects, badges, tools, laptops, cables, and people explaining things with the universal engineer’s gesture: pointing at a tiny part while saying, “So this bit here is the problem.”

Badge hacking became a major focus. Attendees created demos, experiments, music, visual effects, firmware modifications, and strange little programs that made the badge feel alive. The RGB screen, keyboard, speaker, GPIO options, BASIC interpreter, and firmware access made it a flexible playground. Instead of a souvenir that ended up in a drawer, the badge became a shared creative challenge.

Live IDM and DJ sets added to the atmosphere, turning the event into something closer to a hacker festival than a standard technical conference. The combination of electronic music, embedded systems, and real-time tinkering created a mood that was both productive and joyfully impractical. That is a compliment.

Why the Badge Still Matters

The Hackaday Belgrade 2018 badge matters because it represents a high point in conference badge culture. In many communities, badges are simple identifiers. In hardware hacking culture, badges can be fully programmable devices, artistic canvases, networking tools, learning platforms, and collectible artifacts.

This badge stood out because it was not merely flashy. It was technically rich. The BASIC interpreter made it approachable. The keyboard made it self-contained. The screen enabled graphics. The speaker invited music. The microcontroller and firmware invited deeper modification. The CP/M and Z80-related features gave retro-computing enthusiasts something extra to chew on.

The badge also encouraged different levels of participation. A beginner could type BASIC commands and make something happen. An intermediate hacker could write programs or experiment with serial communication. An advanced embedded developer could dive into the firmware, toolchain, memory limits, and hardware expansion options. That layered design is one of the reasons people continued exploring the badge long after the event ended.

SEO Perspective: Why “Hackaday Belgrade 2018” Is Still Search-Worthy

From an SEO and content strategy perspective, “Hackaday Belgrade 2018” is a niche keyword, but it has durable value. It connects several evergreen topics: hardware hacking conferences, retro computing, electronic badges, open-source hardware, BASIC programming, embedded systems, and maker culture in Europe.

People searching for this term may be looking for the event schedule, the badge details, firmware information, speaker names, project inspiration, or historical context. A strong article should therefore do more than repeat the event date. It should explain why the conference mattered, what the badge did, who contributed, and how the event fits into the broader Hackaday ecosystem.

Related keywords such as “Hackaday badge,” “retro computing badge,” “hardware hacking conference,” “BASIC interpreter badge,” “open source hardware,” and “Hackaday Belgrade badge” can be used naturally throughout the content without turning the article into a robotic keyword smoothie. Search engines reward usefulness, and humans reward not being bored into a coma. Conveniently, both goals point in the same direction.

Lessons from Hackaday Belgrade 2018

The biggest lesson from Hackaday Belgrade 2018 is that great technical events are built around shared artifacts and shared curiosity. The badge gave everyone a common starting point. The talks gave context and inspiration. The workshops gave hands-on learning. The hacker village gave people permission to play, fail, fix, and show off.

Another lesson is that retro computing remains powerful because it makes systems understandable. Modern devices can feel sealed, abstract, and suspiciously allergic to screws. A retro-inspired badge with BASIC, a visible keyboard, and hackable firmware makes computing feel tangible again. You can see the machine. You can type into it. You can make it beep. There is a certain magic in that, even if the beep is objectively annoying after the 300th time.

Finally, Hackaday Belgrade 2018 showed that hardware communities thrive when art, science, engineering, and play are allowed to collide. A conference that can include acoustic levitation, stem cell research, PCB art, blimps, soldering robots, FPGA design, and a chorus of badge-generated tunes is not just an event. It is a reminder that technology is most exciting when it refuses to stay in its assigned lane.

Experience Section: What It Felt Like to Be Around Hackaday Belgrade 2018

Imagine arriving at Hackaday Belgrade 2018 and realizing within minutes that this was not going to be a normal conference day. Instead of politely collecting a passive name badge, you received a tiny computer with a keyboard, screen, speaker, and enough personality to make your laptop feel emotionally unavailable. The first experience was probably curiosity: What does it run? Can I program it? Why are there so many keys? Is this a badge, a computer, or a small electronic pet demanding attention?

The next experience was sound. Clicky buttons were everywhere. In a room full of hardware people, a 55-key badge is not quiet for long. Someone tests BASIC. Someone else finds a music feature. Another attendee begins exploring the display. Nearby, a person with a laptop and cable is clearly attempting something more ambitious, possibly brilliant, possibly cursed. That is the beauty of a Hackaday-style event: both outcomes are acceptable as long as the learning is good.

The talks added a steady rhythm to the day. One moment, attendees were hearing about wearable electronics and biological research. Later, they were thinking about acoustic levitation, robot soldering, FPGA development, and how to build a microcomputer without a conventional microprocessor. The mental gear changes were part of the fun. Hackaday Belgrade 2018 did not ask people to remain inside one discipline. It encouraged them to wander between them like a curious raccoon in a laboratory.

The workshops likely felt especially valuable because they transformed ideas into motion. PCB art made circuit boards feel less like anonymous green rectangles and more like designed objects. E-textiles showed that electronics can be soft, expressive, and wearable. FPGA development opened the door to a different way of thinking about digital systems. These sessions gave attendees practical skills, but they also expanded what “hardware hacking” could mean.

As the day moved toward the hacker village phase, the energy changed from presentation mode to creation mode. Tables became workbenches. Badges became instruments, terminals, screens, experiments, and puzzles. People compared discoveries. Small problems turned into group investigations. The phrase “try this” probably did heroic amounts of work. This is where community becomes more than a slogan: people learn faster when they are surrounded by others who are equally excited to break and rebuild things.

The experience of Hackaday Belgrade 2018 also had a strong social dimension. A good hardware conference is not only about the projects on display; it is about the conversations those projects start. A badge demo might lead to a discussion about memory limits. A PCB design might lead to a debate about manufacturing tricks. A talk about conservation sensors might inspire someone to rethink low-power field hardware. The best events leave attendees with more ideas than they arrived with, plus a mild concern about luggage space for new parts.

Looking back, Hackaday Belgrade 2018 feels important because it captured a rare balance. It was technical without being dry, playful without being shallow, and ambitious without becoming inaccessible. It gave beginners something to touch and experts something to investigate. It treated hardware not just as a product category but as a creative medium. Most of all, it proved that when a community gathers around open curiosity, even a conference badge can become a legend.

Conclusion

Hackaday Belgrade 2018 remains memorable because it delivered the full hardware hacking experience: strong technical talks, hands-on workshops, a lively hacker village, and one of the most beloved conference badges of its era. The event was not only about showing what people had built. It was about giving everyone in the room a reason to build something next.

The retro-computing BASIC badge perfectly captured the spirit of the event. It was playful, practical, hackable, and just a little outrageous. That combination is exactly what makes Hackaday culture so compelling. Whether you remember the event for the talks, the badge hacks, the workshops, or the sound of hundreds of tiny keys clicking in near-unison, Hackaday Belgrade 2018 deserves its reputation as a standout moment in open hardware conference history.
