If you’ve been following NASA’s latest moon mission, you’ve probably seen headlines about everything from the floating iPhone in Artemis II to its advanced toilet system. And it seems like wearable makers are also capitalizing on this hype, with CircuitMess just announcing a quirky gadget.

Meet NASA Artemis Watch 2.0, a new smartwatch that brings a retro-futuristic look.

What’s so cool about this one?

NASA Artemis Watch 2.0 features a transparent rectangular body, and the design is easily the main attraction here. It has that chunky, sci-fi gadget body that looks more like a prop from an old-school space adventure than a polished mainstream wearable.

The Artemis Watch 2.0 has fairly modest hardware that uses an ESP32 microcontroller with Bluetooth support, allowing it to connect to Android phones and iPhones for incoming notifications. It also includes a gyroscope, accelerometer, temperature sensor, and compass.

It is not trying to compete with premium wearables out there, lacking popular health features like a heart rate sensor or SpO2 tracking. So it won’t be replacing your Apple Watch.

Why software is the real star here

What makes the Artemis Watch 2.0 stand out is its open-source firmware. The wearable can customize the software, build new watch faces and apps, access sensor data, and much more. It houses a USB-C port for both charging and data transfer, which makes it feel less like a true smartwatcha nd more like a tiny wearable project device.

Price and availability

CircuitMess just released the NASA Artemis Watch 2.0 on its official online store for $129. The company is even offering free shipping globally. It is not the most advanced smartwatch out there, despite what its look might suggest, but for those who want something more playful and programmable, this is a solid nerdy product.

Qualcomm is set to ratchet up chip prices in September, and your next gadget upgrade could bear the brunt

The price hike could touch every Snapdragon-powered device category.

The new Qualcomm Snadragon 8 Elite Gen 5

I want you to sit with this for a second. Qualcomm, the company whose Snapdragon chips sit inside your Android phone and tablet, your Windows laptop, your Meta smart glasses, your Galaxy Watch, and your wireless earbuds, reportedly sent a letter to every major customer telling them prices are going up by double digits.

The price hike will be in effect from September 1, 2026, a recent Bloomberg report claims. Essentially, all the companies placing their chip orders after that will pay a higher price.

Slacked off all summer? Here are 3 fitness trackers that’ll help you stay accountable as you head back to school

Three trackers, three price points, three totally different approaches to keeping you honest about your own goals.

Summer break did what it usually does. Your sleep schedule drifted, workouts happened less often than you'd hoped, and by the time August rolled around, you were feeling it. You've got a plan to get back on track once the school year starts and your days have more structure, but you know how that usually goes. The first two weeks are solid, then the routine quietly slips.

A fitness tracker won't get you off your couch. What it will do is put a number in front of you every day, one that makes it obvious whether you stuck to your goal or slacked off. That small bit of visibility is often the difference between meaning to work out and actually doing it. Back-to-school season is a good time to buy in, since you're already resetting more than one part of your routine, and the overlap makes the habit more likely to stick. To keep the odds in your favor, here are three fitness trackers that can help you stay accountable and actually hit your goals.

Galaxy Watch 9 vs. Watch Series 11: Has Apple finally met its smartwatch match?

From AI-powered health coaching to outdoor fitness tracking, here's how Samsung's Galaxy Watch 9 stacks up against Apple's Watch Series 11.

Wristwatch, Arm, Body Part

These days, the real battleground between smartwatches is who can turn a wrist-worn, sensor-loaded device into something that resembles a personal fitness trainer, and this year's crop of flagship wearables takes that fight more seriously than ever.

Samsung just refreshed its mainstream Galaxy Watch line with a new silicon and a batch of clinically-backed health tools, landing squarely on Apple's home turf of preventive wellness tracking. Apple, for its part, has spent the better part of a year letting its Series 11 sit as the reigning pick for anyone inside its ecosystem, propped up by a software catalog few rivals match feature-for-feature.
