Logitech MX Master 3 vs. 2S Teardown

The Logitech MX Master series of mice is a favorite among the Bolt team. They’re consistently rated as top of the pack among graphic designers, engineering design professionals and everyday users who are looking for a solid wireless mouse.

My Unholy Battle with a Rock64

I’ve got this rock64, which is an aarch64 board comparable to a Raspberry Pi 3 B+ with 4 gigs of ram. For years I’ve wanted to put a distribution on here that doesn’t have a premade image available, mainly because out of all the options on that page I don’t actually like any of them. Well, except NetBSD, but NetBSD…

Reverse-Engineering an IP Camera (2019)

A few days ago I had to replace the old IP camera I use to watch over my dogs and cats, and found out that IP cam technology changed a lot since I bought that old camera.

Your data lived on your C drive, and you were in control. Software was a tool, like a…

A CD Spectrometer (2006)

A simple spectrometer can be built from a CD and a box. Cut a slit on one side of the box. Place the CD on the other side with about 60 degree angle. Look down into the openning on the box. The slit should not be too wide, otherwise the spectrum lines will be blurred. It should not be too narrow either, otherwise the…

Triton: DirectX 11 Driver for QEMU

In the prequel, we introduced Neptune, a Direct3D protocol forwarding layer for VirtIO. Neptune allowed us to serialize Direct3D API calls across the hypervisor boundary and this allowed us to run Wine games on a Linux guest with a Linux host faster than with DXVK directly in the guest. Admittedly, the payoff there…
