Do you want to be a better person? Maybe you want to curse less, drink more water, or post fewer inflammatory comments on the internet. You could go the old school route by wearing a rubber band around your wrist and snapping it every time you slip, or literally pat yourself on the back when […]
Over the last several months, [Aaron Christophel] has been working on creating a custom firmware for cheap fitness trackers. His current target is the “D6 Tracker” from a company called MPOW, which can be had for as little as $7 USD. The ultimate goal is to make it so anyone will be able to write […]
The Charliewatch by [Trammell Hudson] is one of those projects which is beautiful in both design and simplicity. After seeing [Travis Goodspeed]’s GoodWatch21 digital watch project based around a Texas Instruments MSP430-based SoC, [Trammell] decided that it’d be neat if it was more analog. This is accomplished using the CC430F5137IRGZR (a simpler member of the […]
Making your own clothing can be fun, but it’s even better if you can throw some LEDs into the mix and give a new meaning to the term “glow up”. [arturo182] did just that with this custom rocket jacket for CCCamp2019. We’re getting kind of a stained-glass vibe here. To create the jacket, a 3D […]
There are few moments in history that have ever been recorded in more detail or analyzed as thoroughly as the Apollo 11 mission to the Moon. Getting three men to our nearest celestial neighbor and back in one piece took a lot of careful planning, and recording every moment of their journey was critical to […]
Digital watches are a pretty neat idea, and are a great way to experiment with designing and building low-power circuits. That’s what [Eric Min] did with this neat smart watch build. It’s based around an nRF52832 SoC that does all of the heavy lifting, including connecting to a smartphone to get the time when the […]
The folks behind the Atmos Extended Reality (XR) headset want to provide improved accessibility with an open ecosystem, and they aim to do it with a WebVR-capable headset design that is self-contained, 3D-printable, and open-sourced. Their immediate goal is to release a development kit, then refine the design for a wider release. An early prototype […]
The Casio F-91W is probably the most popular wristwatch ever made. It’s been in production forever, it’s been worn by presidents, and according to US Army intelligence it is “the sign of al-Qaeda”. There’s a lot of history in this classic watch. That said, there is exactly one problem with this watch: it’s barely water […]
Jewelry making offers many opportunities for the electronics tinkerer, and on these pages we’ve seen some eye-catching creations using LEDs to great effect. They all have the same limitation though, it’s difficult to power something that tiny without a cumbersome battery. In seeking to solve that problem there have been a variety of inventive solutions […]
Despite the incredible advancements in special effects technology since the film’s release, the dinosaurs in 1993’s Jurassic Park still look just as terrifying today as they did nearly 30 years ago. This has largely been attributed to the fact that the filmmakers wisely decided to use physical models in many of the close-up shots, allowing them […]
