The AirPods Pro “Rattlegate” The first generation of the AirPods was generally regarded as a perfect product. “Apple at its best!” was the universally accepted opinion. I used them for a long time. No speaker issues, no battery issues. Excited for the noise cancelling feature I ordered the AirPods Pro and for the…
Mike Kohn's music, software, and electronics projects.
Introduction ARM CPUs have long dominated the mobile world, nearly all Apple and Android phones and tablets utilize some model of ARM processor. However Intel and AMD still dominate the laptop, des…
Latest on the 3d-printed keyboard switch project: I've reached a switch design that I think is probably reliable enough, and I've put 3 of them together to form a macro keypad just to see how it all goes together before I commit to a full keyboard. I don't have a number for how many presses the switch lasts, other…
You can view a video related to this blog post here: Does UASP make the Raspberry Pi faster?. A couple weeks ago, I did some testing with my Raspberry Pi 4 and external USB SSD drives. I found a USB 3.0 SSD was ten times faster than the fastest microSD card I tested. In the comments on the video associated with that…

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.
Introducing URU Card: an open-source, wallet-sized FIDO2 BLE authenticator based on ESP32, ATECC508A, OLED screen, and MPR121 touch keyboard. Join the project and start building your own secure authenticator.
Extreme refurbishing of a Commodore SX-64 keyboard. Lots of putty, epoxy resin and spray painting with original color and more :)
The revolutionary Intel 8086 microprocessor was introduced 42 years ago this month so I've been studying its die. 1 I came across two 8...
My macOS Big Sur Patcher allowed countless users of older Macs to enjoy the new design and features of macOS Big Sur.
It's late 2020 and you just got a brand-new Mac with Apple's own ARM processors. Exciting! But what will development be like?
All this work was done in November last year. I haven’t worked on it since, but others have shown interest in picking this up, so it’s about time this gets thrown out in the open.
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...
Over and over again, I’ve seen people fix some wireless-related problem and go “wow, I had no idea how much better this could be!" • Wireless protocols often silently operate in an extremely degraded state that makes them substantially worse than wired equivalents.
A version of this article appeared in War on the Rocks. Controlling advanced chip manufacturing in the 21st century may well prove to be like controlling the oil supply in the 20th. The coun…
As much as I love digital instruments, synthesizers and other electronic gear I also really love the look and feel of instruments made from wood, brass, steel and felt. There is objectively no difference between the best digitally sampled pianos but for some reason it doesn’t quite feel as much alive as an actual…
The Intel 8086 microprocessor was introduced 42 years ago this month, 1 so I made some high-res die photos of the chip to celebrate. The ...
A non-comprehensive and opinionated guide to best monitor for programming
ARM Macs are imminent; why they make sense, and why the implications could be far-reaching, for not just Apple but also Intel.
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.
Earlier this week, as part of my work doing a more complete review of the Raspberry Pi 4 (coming soon!), I decided I'd go all-in and spend one entire day working entirely (or at least as much as possible) from a Raspberry Pi. And not just doing some remote coding sessions or writing a blog post—that's easy to do on a…
Recent studies have suggested various side-channel attacks for eavesdropping sound by analyzing the side effects of sound waves on nearby objects (e.g., a bag of chips and window) and devices (e.g., motion sensors). These methods pose a great threat to privacy, however they are limited in one of the
Our software feels less refined as our hardware achieves platonic ideals
From home temperature monitoring to a Kubernetes cluster hosting a live Drupal website, I have a lot of experience running Raspberry Pis. I've used every model through the years, and am currently using a mix of A+, 2 model B, and 4 model B Pis. The 3 model B+ was the first generation that had me concerned more about…
