How low we can Go and still do something useful? I recently bought this ridiculously cheap board: I bought it for three reasons. First, I have never dealt (as a programmer) with STM32F0 series. Second, the STM32F10x series is getting old. MCUs belonging to the STM32F0 family are just as cheap if not cheaper and has…

Is it OK to daisy chain UPSs? Let’s look at a few reasons this is a common question and alternative approaches that can better address the target.
I feel like I used to spend an inordinate amount of time dealing with suspect hard drives. I mean, like, back in high school. These days I almost never do, or on the occasion that I have storage trouble, it's a drive that has completely stopped responding at all and there's little to do besides replacing it. One time…
The first mass market optical media
If you'd asked me a few years back if I thought I'd buy a 3D printer, I would have said no. My experience of 3D printers back when I was in college was that they were very slow, expensive, frequently failed mid-print, and needed constant calibration...
Most software developers prefer to work on "fast" computers, and I am normally one of them. Many of my tools work best with lots of memory, ...
I am pleased to announce that pre-orders for the PinePhone BETA Edition will open on March 24. The PinePhone BETA Edition is powered by KDE Plasma Mobile and Manjaro Linux.
Following these steps, you will add hardware acceleration decoding capabilities to the Chromium web browser. This is an extension to the tutorial about DRM for Chromium on the Raspberry Pi. Videos from Amazon Prime, Netflix, Disney+, Youtube, etc. can be decoded using the Raspberry Pi GPU.
Most MiniDisc aficionados are aware of unit hacking to gain access to new features. The unit that perhaps benefits the most from this is the Sony MZ-N510, which also comes in the N520 and NF610 variants. The 2001 model R700 can be hacked to add many features of its upscale brother, the R900 , as well as the Type-R…
A Field-Programmable Gate Array (FPGA) can implement arbitrary digital logic, anything from a microprocessor to a video generator or crypt...
A tale of debugging hardware with unconventional methods. How I perfected the firmware of BrakeBright (a motorcycle safety device) using a vibrator.
Get started running LLMs with PyTorch on Windows using AMD consumer graphics hardware.
How to calculate sensor error, compare measurements, and use metrics like RMSE to judge air quality sensor performance.
This is part 2 of a series on PC floppy copy protection methods. You can read Part 1, covering Formaster Copy-Lock here . Softguard System...
The Goal – Explain What is Magic Leap Doing Magic Leap has a way of talking about what they hope to do someday and not necessarily what they can do anytime soon. Their patent applications ar…
In 1980, Intel introduced the 8087, a chip that made floating-point operations much faster in the IBM PC and other systems. Although the 808...
When learning a new programming language, I like having a well defined yet non-trivial problem to solve. Conway’s Game of Life (GoL) fits this definition. It has enough depth to uncover various tradeoffs. So naturally, when I picked up Chisel hardware description language (HDL), I wanted to build Game of Life in FPGA…
Zigfrid is the end result of my RFID tinkering. Since I will most definitely forget most things described here in the (very) near future, I share this for those few who might find it interesting. P…
RISC-V Community News Success in the mobile and consumer device market depends on a vibrant software ecosystem. Over the past decade the Android Open Source Project (AOSP) has become one...
Cryptography tells us how to make a chain of trust rooted in special-purpose chips known as secure elements. But how do we come to trust our secure elements? I have been searching for solutions to this thorny supply chain problem . Ideally, one can directly inspect the construction of a chip, but any viable inspection…
Extreme refurbishing of a Commodore SX-64 keyboard. Lots of putty, epoxy resin and spray painting with original color and more :)
Discover hardware product teardowns to learn about key design for manufacturability and mechanical design principles.
Update: Just to clarify, this post is speculation, not fact. Based on the excellent iFixit teardowns it looks like the iPad 2 headphone jack has pins on both sides , which is more in line with Apple's typical cantilever design (roughly similar to the jack in the Macbook Air ). Interestingly, it looks like the…
