A decade ago, smartwatches were an unexplored avenue full of exotic promise. There were bleeding-edge and eye-wateringly expensive platforms from the likes of Samsung or Apple, but for the more experimental among technophiles there was the Pebble. Based on a microcontroller and with a relatively low-resolution display, it was the subject of a successful crowdfunding campaign and became quite the thing to have. Now long gone, it has survived in open-source form, and now if you’re a Pebble die-hard you can even buy a new Pebble. We’re not sure about their choice of name though, we think calling something the “Core 2 Duo” might attract the attention of Intel’s lawyers.

The idea is broadly the same as the original, and remains compatible with software from back in the day. New are some extra sensors, longer battery life, and an nRF52840 BLE microcontroller running the show. It certainly captures the original well, however we’re left wondering whether a 2013 experience still cuts it in 2025 at that price. We suspect in that vein it would be the ideal compliment to your game controller when playing Grand Theft Auto V, another evergreen 2013 hit.

We look forward to seeing where this goes, and we reported on the OS becoming open source earlier this year. Perhaps someone might produce a piece of open source hardware to do the same job?

While we’d like to think that pandemics and lockdowns are behind us, the reality is that a warming climate and the fast-paced travel of modern life are a perfect storm for nasty viruses. One thing that could help us curb the spread of the next pandemic may already be on your wrist.

Researchers at Aalto University, Stanford University, and Texas A&M have found that the illness detection features common to modern smartwatches are advanced enough to help people make the call to stay home or mask up and avoid getting others sick. They note we’re already at 88% accuracy for early detection of COVID-19 and 90% for the flu. Combining data from a number of other studies on smartwatch accuracy, epidemiology, behavior, and biology, the researchers were able to model the possible outcomes of this early detection on the spread of future diseases.

“Even just a 66-75 percent reduction in social contacts soon after detection by smartwatches — keeping in mind that that’s on a par with what you’d normally do if you had cold symptoms — can lead to a 40-65 percent decrease in disease transmission compared to someone isolating from the onset of symptoms,” says Märt Vesinurm.

We’ve got you covered if you’re looking for a smartwatch that looks a bit like a hospital wristband and we’ve also covered one that’s alive. That way, you’ll have a slimy friend when you’re avoiding other humans this time around. And when it’s time to develop a vaccine for whatever new bug is after us, how do MRNA vaccines work anyway?
