The Honda Goldwing is one of the more famous motorcycles ever produced. It’s known for its reliability and comfort, but also for being one of the first motorcycles Honda rolls out new technology with. It was the first to have a factory-installed airbag as well as integrated GPS, and is now largely associated for being a sort of two-wheeled RV with how many creature comforts it supports for long-distance riders. [Matt] has a Goldwing of his own, and is taking that RV-like feeling to the extreme with a rooftop camper for this motorcycle.

Of course, motorcycles don’t have roofs, but if this Goldwing had one this camper would definitely be above that. Goldwings are already heavy enough without an enormous weight dramatically increasing the center of gravity, and [Matt] certainly had his problems with that along the way. But before this adventure he had modified it into a hill climber, removing a lot of the extraneous equipment from it. Attaching some metal frame and a lightweight camper shell to it didn’t seem like too much of a stretch from there, so he got to work with a welder. At the end he has a box that’s just barely big enough for him to sleep in but is more or less functional as a camper.

Perhaps unsurprisingly, [Matt] dropped this more than once on its maiden voyage, and one of those falls damaged a wiring harness that caused his battery to drain in the night. Luckily he was not too far from home on the test drive. We’d tend to think that this camper won’t be one that [Matt] keeps working on (although we’d imagine a tricycle kit might solve his center of gravity issues) but since he’s built some other interesting campers in the past we’re not too sure we’d count this one out just yet.

Printed circuit boards were developed first for function over form. They were a way to mount components and connect them in a stable, robust fashion, while taking into regard things like packaging and cooling requirements to enable a circuit to function. Circuit boards often end up looking cool in a techy kind of way, but their aesthetic is usually very much secondary to their actual purpose.

Katrin Dietzsch likes to use her PCBs a little differently, however. She designs boards that are intended to be a narrative tool for tabletop roleplaying, and came down to Hackaday Europe 2026 to walk us through the development of this very whimsical hardware.

Roll For It

Katrin starts her talk by explaining how she came to design circuits specifically for tabletop gaming. She saw an opportunity to combine her hardware hobby with the world of TTRPGs to help maintain both hobbies amidst a busy lifestyle. She also found that hardware she built could be a great artistic medium for supporting mystery and storytelling in the tabletop world. With the right design, her circuits became very much part of the narrative themselves.

How does one create a piece that becomes special, rather than just being another art project thrown in a drawer, though? Katrin notes that meaningful objects are the ones that gather stories about them and gain emotional baggage, and thus, relevance. Interaction is also key; she relates the familiar tale that many of us have yelled at a printer before. We often anthropomorphize objects or assign them personalities just because they have some level of strange behaviour, or even if they just blink at us. Often, she’ll also start a build not from specs, but from story and the game itself. The questions asked are about how to engage players, and how to help them reach their goals, and answering those can help guide the design process.

There are also elements drawn from typical ideas around magic and artifacts that can be drawn from. For example, many tabletop roleplaying games feature the concept of attunement, where a character may have to physically and spiritually connect with an object to access its magical features. This is something that can be readily recreated in the electronic world with the use of things like capactive touch sensing. Katrin also notes that using RF can be great for creating items or puzzles that respond based on proximity, and there is all sorts of fun to be had with things like IR beams, motors, switches, or whatever else players can interact with. Code is also a beautiful place to hide secrets and easter eggs—you get to write the behaviour of the device to be as beguiling and confounding as you like.

There’s also the visual side of things. It’s something that should be remarkably familiar to anyone who has been to a modern hacker or maker convention and seen the wonderful variety of badge designs created by the community. Everything from the copper layers to the silkscreen to the very routing of the fiberglass board itself can be leveraged to create an art piece that captivates and inspires. Particularly in this era when it’s so easy to find board houses that will produce your designs with soldermask in all the colors of the rainbow. Katrin’s wonderful D20 PCB serves as the perfect example of these techniques being applied well.

Like any good tabletop aficionado, Katrin has a great sense of practicality too. There’s no point designing some fantastic electronic gizmo for your game if you can’t afford the bill of materials, can’t solder the parts, or your players can’t figure out how they’re supposed to use an in-circuit programmer to interact with it. Most of us live very busy lives, so our hobby projects have to be achievable within the constraints of our lifestyle. She also notes that it’s great if you build something with longevity, rather than something that serves only as a single-use tchotchke for a one-off bit.

If you’ve ever contemplated bringing your electronics skills to bear in your role as a dungeon master, Katrin’s talk is a great place to start. Your little creations can serve as a wonderful bridge between your player’s experience and the world of imagination you’re collectively creating, and that’s always a fun time!
