Bluetooth is everywhere, but it’s hard to inspect. Most of the magic is done inside a Bluetooth controller chip, accessed only through a controller-specific Host-Controller Interface (HCI) protocol, and almost everything your code does with Bluetooth passes through a binary library that speaks the right HCI dialect. Reverse engineering these libraries can get us a […]
Some synthesizer sounds are just catchy, but some of them are genre-defining. We think you could make that case for the Roland JP-8000 patch “Sandstorm”, which you’ve heard if you listened to any trance from the 90’s, but especially the song that was named after it. “Sandstorm” is powered by the Roland Supersaw, and synth […]
Many of us have them, few of us really hack on them: well, here we’re talking about large home appliances. [Severin von Wnuck-Lipinski] and [Hajo Noerenberg] were both working on washing machines, found each other, and formed a glorious cooperation that ended in the unholy union of German super-brands Miele and B/S/H — a Miele […]
Although something that’s taken for granted these days, the ability to perform floating-point operations in hardware was, for the longest time, something reserved for people with big wallets. This began to change around the time that Intel released the 8087 FPU coprocessor in 1980, featuring hardware support for floating-point arithmetic at a blistering 50 KFLOPS. […]
In a recent video, [Andrew Zonenberg] takes us through the process of decapsulating a PIC12F683 to take a peak at its CMOS implementation. This is a multipart series with five parts done and more to come. The PIC12F683 is an 8-pin flash-based, 8-bit microcontroller from Microchip. [Andrew] picked the PIC12F683 for decapsulation because back in […]
Apple’s AirPods can pair with their competitors’ devices and work as basic Bluetooth earbuds, but to no one’s surprise most of their really interesting features are reserved for Apple devices. What is surprising, though, is that simple Bluetooth device ID spoofing unlocks these features, a fact which [Kavish Devar] took advantage of to write LibrePods, […]
Ever wonder what happens to those digital price tags you see in stores once they run out of juice? In what is a prime example of e-waste, many of those digital price tags are made with non-replaceable batteries, so once their life is over they are discarded. Seeing an opportunity to breathe new life into […]
The infrared transceiver installed on the washing machine. (Credit: Severin) Since modern household appliances now have an MCU inside, they often have a diagnostic interface and — sometimes — more. Case in point: Miele washing machines, like the one that [Severin] recently fixed, leading to the firmware becoming unhappy and refusing to work. This fortunately […]
The arrival of cheap thermal printer mechanisms over the last few years has led to a burst of printer hacking in our community, and we’re sure many of you will like us have one knocking around somewhere. There are a variety of different models on the market, and since they often appear in discount stores […]
When the files on the Titan submersible disaster were published, most people skimmed for drama. Hackers, however, would likely zoom in on the hardware autopsy. [Scott Manley] actually did this. He faced a hacker’s nightmare: three crushed PCs, bent SSDs, and an encrypted SD card from a camera that survived six kilometres under pressure, all […]
