Maker Konrad Wohlfahrt has turned a Seeed Studio XIAO nRF52840 growth board into watch impressed by the one worn by Artyom within the Metro franchise — designed, its creator says, to be nostalgic but purposeful.
“There’s all the time been one thing tremendous cool about bringing fictional devices and instruments to life. Holding a real-life model of one thing out of your favourite sport or film? That’s simply an superior feeling,” Wohlfahrt writes. “Now, a lot of the stuff you recreate in all probability will not be tremendous helpful in day-to-day life. However what in case you might construct one thing that truly is helpful — and nonetheless offers you that nostalgic kick? I’ve performed all of the Metro video games and completely love them. One gadget actually stood out to me: Artyom’s wristwatch. It really works as a gasoline masks timer and a visibility indicator within the sport. I believed, ‘Hey, this may make a cool first electronics venture!’ Spoiler: it wasn’t.”

Wohlfahrt’s venture is one thing of a throwback, and never simply to the favored Metro collection of post-apocalyptic shooters which launched in 2005 with Metro 2033: the explanation Wohlfahrt is aware of it wasn’t a very good venture for an absolute newbie is as a result of he began it when he himself was an absolute newbie. “I failed at it. Lots,” he admits. “However now? Issues are totally different. Through the years, I’ve realized the way to design circuits, make PCBs, solder correctly, and write code. So now it is lastly time to return to that superior little gadget… and construct it for actual.”
The reproduction watch is predicated on a compact Seeed Studio XIAO nRF52840 growth board, itself that includes the Nordic Semiconductor nRF52840. The show makes use of a quartet of seven-segment LEDs in a fetching yellow, rather than the in-game watch’s iconic Nixie tubes. An inside 100mAh battery retains every little thing ticking over, with a CR927 battery for teh real-time clock — an Analog Gadgets DS1302. A round PCB connects every little thing collectively, and a metallic mesh completes the simulated Nixie look.

“Like with any venture, there’s all the time room for enchancment, however in some unspecified time in the future, it’s a must to name it completed,” Wohlfahrt writes. “I am actually curious to see the way it holds up in every day use. I am optimistic that it will final far longer than my early makes an attempt. And that is the most important takeaway right here: even in case you fail at first, maintain going. Continue learning. Then, while you attempt once more, you’ll discover the venture is way simpler together with your new abilities and information. I realized that the laborious method — that is the fifth iteration of this watch. However hey, that is progress!”
The venture is documented in full on Instructables; Wohlfahrt has additionally launched supply code, schematics, and 3D print recordsdata on GitHub underneath an unspecified license.
