Testing Phone-Sized Faraday Bags
Complex software is, to put it mildly, hard to get right (for details, see almost any other posting on this or any other security blog). Especially for gadgets that are rich with microphones, cameras, location and environmental sensors, and communication links (such as, you know, smartphones), errors and security…

Turing Pi 2: 4 Raspberry Pi nodes on a mini ITX board
Last year I spent a bit of time building a Kubernetes cluster with the original Turing Pi. It was fun, and interesting, but ultimately the performance of the Compute Module 3+ it was designed around led me to running my homelab off some newer Pi 4 model B computers, which are at least twice as fast for almost…

Researchers shrink camera to the size of a salt grain
Researchers at Princeton University and the University of Washington have developed an ultracompact camera the size of a coarse grain of salt. The new system can produce crisp, full-color images on par with a conventional compound camera lens 500,000 times larger in volume.

The Secret History of ATAPI
The other day I asked myself a seemingly trivial question: What was the first ATAPI CD-ROM drive and when was it available? Given that ATAPI was a major technology which instantly obsoleted all proprietary CD-ROM interfaces and made SCSI much less desirable, one might expect that there would have been some press…

Mini-ITX Seaberry Adds 11 PCIe Slots to a Raspberry Pi
Since the Compute Module 4 came along last year, there have been a few projects that use it that make me do a double-take: They did what with a Pi? Alftel's Seaberry is a carrier board for the CM4 in the Mini ITX form factor that adds on eleven PCI Express slots: 1 x16 slot (with x1 lane) in the standard ITX location…

The unbearable fussiness of the smart home
As we head into another gifting season and more and more connected devices make their way onto gift guides, I want to offer a cautionary note. The smart home is like a cat — mostly self-sufficient and nice to have, but also possessing a mind of its own that can lead to frustration and confusion […]

TPM Sniffing
TL;DR : we reproduced Denis Andzakovic’s proof-of-concept showing that it is possible to read and write data from a BitLocker-protected device (for instance, a stolen laptop) by sniffing the TPM key from the LCP bus.

I built a $5k Raspberry Pi server (yes, it's ridiculous)
When I heard about Radxa's Taco—a Raspberry Pi Compute Module 4-powered NAS/router-in-a-box—I knew what must be done. Load it up with as much SSD storage as I can afford, and see what it can do. And after installing five Samsung 870 QVO 8TB SSDs and one Sabrent Rocket Q NVMe SSD—loading up every drive slot on the Taco…

IoT Nixie Tubes
Every day I make a cup of coffee, organize a list of the things I want to do that day, and try to work through it. Every time I finish one of the tasks, I mark it as complete. By the end of the day, ideally there are no things left on the list, but if there are, I’ll move them into a backlog and start fresh the next…
