A Smartwatch You Can Easily Build Yourself

The concept of a smartwatch was thrown around for a long time before the technology truly came to fruition. Through the pursuit of miniaturisation, modern smartwatches are sleek, compact, and remarkably capable for their size. Companies such as Apple and Samsung throw serious money into research and development, but that doesn’t mean you can’t create something of your own. [Electronoobs] has done just that, with this Arduino-based smartwatch build.

The brain of the watch is that hacker staple, the venerable ATmega328, most well known for its use in the Arduino Uno and Nano platforms. An FTDI module is used for …read more

Heartwatch Monitors Your Ticker

The heart! A pump of the most fantastical kind, it is capable of operating for decades without rest. It’s responsible for supplying vital oxygen to the body’s subsystems, and can be readily monitored with modern technology. [Dave Vernooy] wanted to build a watch that could take heartrate and blood oxygen measurements – so he did.

Named Heartwatch, the device is a DIY smartwatch build with a bunch of exciting features. Heart monitoring is taken care of by the MAX30102 sensor which integrates all the hardware to sense heart rate and oxygen saturation into a single tiny plastic package. There’s then …read more

A Watch Only A Ham Can Use

We’re not sure what to make of this one. With the variety of smartwatches and fitness trackers out there, we can’t be surprised by what sort of hardware ends up strapped to wrists these days. So a watch with an RPN calculator isn’t too much of a stretch. But adding a hex editor? And a disassembler? Oh, and while you’re at it, a transceiver for the 70cm ham band? Now that’s something you don’t see every day.

The mind boggles at not only the technical prowess needed to pull off what [Travis Goodspeed (KK4VCZ)] calls the GoodWatch, but at the …read more

80’s Smartwatch Finally Plays Tetris

While the current generation of smartwatches have only been on the market for a few years, companies have been trying to put a computer on your wrist since as far back as the 80s with varying degrees of success. One such company was Seiko, who in 1984 unveiled the UC-2000: a delightfully antiquated attempt at bridging the gap between wristwatch and personal computer. Featuring a 4-bit CPU, 2 KB of RAM, and 6 KB of ROM, the UC-2000 was closer to a Tamagotchi than its modern day counterparts, but at least it could run BASIC.

Ever since he saw the …read more

Controlling This Smartwatch is All in the Wrist

Smartwatches are pretty great. In theory, you’ll never miss a notification or a phone call. Plus, they can do all kinds of bio-metric tracking since they’re strapped to one of your body’s pulse points. But there are downsides. One of the major ones is that you end up needing two hands to do things that are easily one-handed on a phone. Now, you could use the tip of your nose like I do in the winter when I have mittens on, but that’s not good for your eyes. It seems that the future of smartwatch input is not in available …read more
