When I placed the last screw on the DB4 chassis of the Beautiful Silent PC [1] , I thought I would not have to open it up again for years. Perhaps, I hypothesized, it would be a decade before an upgrade. The beautiful silent PC. The imperative of working from home proved me wrong when the seemingly easy problem of…
Listen, anyone can make a PCB at home, it’s easy. PCBs (printed circuit boards) are those flat things with all the components that are inside all electronic devices, you’ve seen them. All you need is a laser printer, some glossy magazine pages, print your circuit onto the page, use a clothes iron to transfer the toner…
Using Python 3.6, OpenCV, Dlib and the face_recognition module
Note: This post originally appeared as an update in the crowdfunding campaign for Precursor.
In these videos, I talk about how VGA signals work and build a circuit that provides the correct timing of sync signals so that a monitor recognizes the signal and displays an image stored on an EEPROM.
With the benefit of hindsight, this was a naïve question: > Alright clever IoT folks, I've got two of these garage door openers, what do you reckon the best way of connecting them with Apple HomeKit is? https://t.co/i0RmjSMkkD — Troy Hunt (@troyhunt) April 25, 2020 [https://twitter.com/
Motivation Despite using a FTTH internet connection since 2014, aside from the one fiber uplink, I had always used network gear with 1 Gbit/s links over regular old rj45 cat5(e) cables. I liked the simplicity and uniformity of that setup, but decided it’s time to add at least one fiber connection, to get rid of a…
The amount of time my outdoor cameras are being set off by light, wind, cars, or anything other than a human is insane. Overly cautious security cameras might be a feature, but an annoying one at that...
In my previous blog post, I compared the performance of my new ARM-based MacBook Pro with my 2017 Intel-based MacBook Pro. I used a number parsing benchmark. In some cases, the ARM-based MacBook Pro was nearly twice as fast as the older Intel-based MacBook Pro. I think that the Apple M1 processor is a breakthrough ……
In 2018, I gave an talk at Hackaday Supercon that was basically Phased Arrays 101. You can watch it at the bottom of this post.
This article is now available in Russian: Реверс-инжиниринг TL431, крайне распространенной микросхемы, о которой вы и не слышали . A die p...
These are my first impressions of the new Raspberry Pi 400, and my experiences of setting it up as a machine for development and blogging.
Apple Silicon changes everything for Broadway electronic music designers. The new M1 Mac mini is capable of running high-end sample libraries and virtual instruments in a stable manner, and it's only going to get better with M2, M3, and M4-series chips in the future.
A comprehensive deep dive into the design of Roland's legendary DCO

Starting with the release of the Pixel 3, all of Google's Pixel Android smartphones come with the Titan M security chip on board. When I realized the Pixel 3a XL I purchased also had it, I decided to try to take advantage of it in an app I work on. It turned out that using the Titan M chip through the Android Keystore…
The Pinebook Pro is a $200 laptop with ARM processors that promises a lot. Does it deliver?
After seeing the work done by Thomasz Mloduchowski and Colin Riley with managing to bridge the Raspberry Pi 4's PCI-Express bus to a USB 3.0 port, and then seeing these comments on hack-a-day, I thought I would give it a go too! So, here's a PCIe bridge chip that simply replaces the VL805 USB 3.
Laptop makers have long shortchanged AMD-based offerings. Read on to find out how they can avoid common mistakes that limit the potential of their products.
FM radio headphones were given out at the door. Each set was tuned beforehand to receive a broadcast from my programmed station. Visitors were then invited to walk around the room, contemplating the artifacts of the exhibit.
Recently I realised that, as part of his 8086 reverse-engineering series, Ken Shirriff had posted online a high resolution photograph of the 8086 die with the metal layer removed . This was something I have been looking for for some time, in order to extract and disassemble the 8086 microcode. I had previously found…
I took me 7 years to admit I'd made a mistake in choosing a Z-Wave Wireless Lighting System. Finally I've taken stock and replaced it!
The Intel 8086 microprocessor is one of the most influential chips ever created; it led to the x86 architecture that dominates desktop an...
Here, I provide an in-depth analysis of GPUs for deep learning/machine learning and explain what is the best GPU for your use-case and budget.
