Google recently launched GPUs on Google Cloud Platform (GCP), which will allow customers to leverage this hardware for highly parallel workloads. These GPUs are connected to our cloud machines via a variety of PCIe switches, and that required us to have a deep understanding of PCIe security.
What’s the real reason that cellphone manufacturers stopped fitting this simple, robust connector?
How the instruction set for RISC-V processors has been designed cleverly for both simplicity and high performance.
An experiment to design a cute PCB (without touching any tools) in plain English
The Fairphone 6 is an interesting target for mainline Linux and postmarketOS for a few reasons:
We’re very excited to be making a Flow preview available for public download on the Raspberry Pi 400.
The updated MIDI 2.0 specifications have been released, so we're opening the repo to the public.
A visual step-by-step guide to Joseph Whitworth’s three-plate method for creating very flat reference surfaces.
Today I’m publishing tihle, a new emulator targeting TI graphing calculators (currently only the 83+, but maybe others later). There’s rather a lot to say about it, but here I will discuss the motivation for a new emulator and the state of the art followed by technical notes on the design and initial development…
The world’s current and next innovations depend on a single country: Taiwan. It’s probably one country you might never hear about, or perhaps confuse with its neighbor, Thailand, or even think it’s a part of China. I’ve been living in Taiwan for 3+ years, and am baffled that I never pay attention to semiconductors…
Light can transmit more data while consuming far less power than electricity, and an engineering feat brings optical data transport closer to replacing wires.
Learn electronics by working through real designs, builds, and stubborn bugs at the bench. You’ll get practice making your own boards and understanding what they do when you power them up.
The story behind Zusie begins in May 2008, when I went on vacation to Berlin for a few days with a friend. As is my habit, I looked for interesting technical or scientific sites to visit, and the main thing to visit was the Technische Museum. I think I spent a full day day there, to the expressed dismay of my friend…
Hardware Bugs can be frustrating, as they are likely the last place you would expect a bug. Unfortunately, they can and do happen. Most likely every CPU has a list of erratas. This post outlines th…
Measure with Music: How to Read Analog Sensors Using a PC Sound Card
Way back in 2012, The Guardian reviewed an eInk reader which cost a mere £8. The txtr beagle was designed to be a stripped-down and simplified eReader. As far as I can tell, it never shipped. There were a few review units sent out but I can't find any evidence of consumers getting their hands on one. Also, that £8…
The third-generation AirPods deliver powerful audio features and a magical wireless headphone experience in a new contoured design.

Hard drives fail. With the new iMac from Apple, when the main drive does fail, there is no DIY replacement option available.
Repair of a TI-83 Plus calculator with a non-working screen
I’ve started work on the next in my 1-bit Woodblocks series: “Tekagami” (Ito Shinsui’s “Hand Mirror”). So it’s a good time to talk about how I turned an iPad...

Update 2025-03-05 : @jxu has shared a collection of simplified examples that are even easier to follow than the original ones in this post.
Durability is the guarantee that data can be accessed after a failure. It seems like this should be very simple: either your system provides durable data storage, or it does not. However, durability is not a binary yes/no property, and instead should be defined as the kinds of failures you want your data to survive…
I built a robot that mixes drinks named Bar Mixvah. It utilizes an Arduino microcontroller switching a series of pumps via transistors on the physical layer, and the MEAN stack (MongoDB, Express.js, Angular.js, Node.js) and jQuery for the frontend and backend. In this post, I’ll teach you how I made it. You can follow…
Surprised at CES 2017 – Avegant Focus Planes (“Light Field”) While at CES 2017 I was invited to Avegant’s Suite and was expecting to see a new and improved and/or a lower cost ver…
