Although a somewhat common feature on cars these days, tire pressure sensors (TPS) are also useful on bicycles. The SKS Airspy range of TPS products is one such example, which …read more Continue reading Reverse-Engineering SKS Airspy Tire Pressure Sensors for Custom Firmware
If something has a “smart” in its name, you know that it’s talking to someone else, and the topic of conversation is probably you. You may or may not like …read more Continue reading Smartwatch Snitches on Itself and Enables Reverse Engineering
Over the past two decades, e-paper has evolved from an exotic and expensive display technology to something cheap enough to be used for supermarket price tags. While such electronic shelf …read more Continue reading Low Power Challenge: E-Paper Shelf Label Becomes Ultra-Frugal Clock
Have you ever come across an interesting chip or component that you wanted to experiment with, only to find that there doesn’t seem to be a development board for it? Spinning up your own board is a lot easier today than it has been in the past, but it’s still …read more

[Aaron Christophel] has been busy, he picked up a P8 smartwatch of the type that many of you will no doubt have seen. They cost almost nothing and do almost… nothing. In all fairness, they do connect to your phone using Bluetooth LE courtesy of a chip from Nordic (the …read more

Apparently, there is a wrist-mounted device that delivers electric shocks to the wearer when it receives the appropriate command over Bluetooth. No, it’s not part of some kind of house arrest program. If you can believe it, the gadget is actually intended to help break bad habits or wake up …read more
The search for the ultimate hacker’s smart watch probably won’t end any time soon. [emeryth] has nominated another possible candidate in the form of the SMA-Q2, and has made a lot of progress in making it accessible.
Also known as the SMA-TIME, the watch is based around the …read more
[André Biagioni] is developing an open hardware bicycle navigation device called Aurora that’s so gorgeous it just might be enough to get you pedaling your way to work. This slick frame-mounted device relays information to the user through a circular array of SK6812 RGB LEDs, allowing you to find out …read more
If you had asked us yesterday what peak nightlight technology looked like, we might have said one of those LED panels that you stick in the outlet. At least it beats one of those little wimpy light bulbs behind the seashell, anyway. But after looking at a detailed teardown of …read more
[Uri Shaked] accidentally touched a GPIO pin on his 3.3 V board with a 12 V alligator clip, frying the board. Sound familiar? A replacement would have cost $60, which for him wasn’t cheap. Also, he needed it for an upcoming conference so time was of the essence. His only option was to try to fix it, which in the end involved a delicate chip transplant.
The board was the Pixl.js, an LCD board with the nRF52832 SoC with its ARM Cortex M4, RAM, flash, and Bluetooth LE. It also has a pre-installed Espruino JavaScript interpreter and of course the …read more
