Over on his YouTube channel [Electronic Wizard] has released a video that explains how infrared (IR) remote controllers work: IR Remote Controllers protocol: 101 to advanced. This video covers the NEC family of protocols, which are widely used in typical consumer IR remote control devices, and explains how the 38 kHz carrier wave is used […]
The “USB C” cable that comes with the Inaya Portable Rechargeable Lamp. (Credit: The Stock Pot, YouTube) Recently [Dillan Stock] over at The Stock Pot YouTube channel bought a $17 ‘mushroom’ lamp from his local Kmart that listed ‘USB-C rechargeable’ as one of its features, the only problem being that although this is technically true, there’s […]
There’s a dedicated group of users out there that aren’t ready to let their beloved IBM PC110 go to that Great Big Data Center in the Sky. Unfortunately, between the limited available technical information and rarity of replacement parts, repairing the diminutive palmtops can be tricky. Which is why [Ahmad Byagowi] has started a project […]
It’s official, we’re living in the future. Certainly that’s the only explanation for how [wrongbaud] was able to write a three-part series of posts on hacking a cheap electric toothbrush off of AliExpress. As you might have guessed, this isn’t exactly a hack out of necessity. With a flair for explaining hardware hacking, [wrongbaud] has […]
A spectrometer is one of those tools that many of us would love to have, but just can’t justify the price of. Sure there are some DIY options out there, but few of them have the convenience or capability of what’s on the commercial market. [Chris] from Zoid Technology recently found a portable spectrometer complete […]
Ever want to get into reverse engineering but don’t know where to start? You’re in luck — [Hash] just dropped a case study in chip glitching that should get you off on the right foot. The object of this reverse engineering effort in the video below is a Microchip SAM4C32C, removed from one of the […]
Every year, USB flash drives get cheaper and hold more data. Unfortunately, they don’t always get faster. The reality is, many USB 3.0 flash drives aren’t noticeably faster than their USB 2.0 cousins, as [Chase Fournier] found with the ultra-cheap specimens purchased over at his local Micro Center store. Although these all have USB 3.0 […]
While the Bus Pirate 5 is an impressive piece of hardware, the software is arguably where the project really shines. Creator [Ian Lesnet] and several members of the community are constantly working to add new features and capabilities to the hardware hacking multi-tool, to the point that if your firmware is more than a few […]
[Ken Shirriff] has been sharing a really low-level look at Intel’s Pentium (1993) processor. The Pentium’s architecture was highly innovative in many ways, and one of [Ken]’s most recent discoveries is that it contains a complex circuit — containing around 9,000 transistors — whose sole purpose is to multiply specifically by three. Why does such […]
Last year, we’ve featured a super cheap smart ring – BLE, accelerometer, heart sensor, and a battery, all in a tiny package that fits on your finger. Back when we covered it, we expected either reverse-engineering of stock firmware, or development of a custom firmware outright. Now, you might be overjoyed to learn that [Wesley […]
