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.

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.

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
