New York Times ☛ Car Parts, Fiberglass and a Dream: How a Teacher Built a Hovercraft
Mr. Tymofichuk’s hovercraft now sails above land and water, a bright red gem coasting over the Saskatchewan River. With speeds that can reach around 40 m.p.h. over water — faster on ice — it might be hard to catch the ingenuity in its Frankenstein design.
The cab was cut from a 1997 Jeep Grand Cherokee; the engine once revved up a 1985 Toyota Celica; and 107 hand-sewn rubber segments, courtesy of Mr. Tymofichuk’s wife, help to direct low-pressure air beneath the craft so that it rises eight inches above the ground.

Kevin Boone ☛ Kevin Boone: Fitting an NVMe disk in a computer with no NVMe support
I am the proud owner of a Lenovo ThinkStation P710. This was a top-of-the-market workstation back in 2015, and it still has some great features. Mine has two 40-core Xeon CPUs with 32Gb RAM each, and it’s… well, rather slow, to be frank. Things have moved on since 2015 and, these days, we’ve become used to the huge speed improvement of NVMe solid-state drives (SSDs), compared to the earlier SATA storage. It’s all very well having 80 CPU cores, but you’ve still got to feed them with work; and all that work is coming from SATA-III disks, which do not impress, by contemporary standards.

Hackaday ☛ Jumperless Breadboard V5 Readies For Launch
When are jumper wires on a breadboard entirely optional? When it’s the latest version of [Kevin Santo Cappuccio]’s Jumperless, which uses a bunch of analog crosspoint switches (typically used for handling things like video signals) to create connections instead of physical wires. There’s even an RGB LED under each hole capable of real-time visualization of signals between components.

CNX Software ☛ M5Stack ESP32-S3-Pico-based devkits: ATOMS3R with 0.85-inch color display, and ATOMS3R Cam with VGA camera
M5Stack ATOMS3R and ATOMS3R Cam are two tiny devkits based on ESP32-S3-Pico system-in-package and a similar design but the first one features a 0.85-inch color color IPS display, while the other is equipped with a GC0308 VGA camera. Both modules measure just 24x24mm with a thickness of around 13mm, integrate BMM150 and BMI270 motion sensors, offer GPIO expansion through female headers and a grove connector, and feature an infrared transmitter and a USB Type-C port for power and programming.

Pi My Life Up ☛ Installing Ubuntu on the Raspberry Pi
Ubuntu is one of the most popular Linux-based operating systems known for striking a good balance between being stable and user-friendly.
One of Ubuntu’s neatest features is its full support for the newer versions of the Raspberry Pi. You get the same full desktop experience that you would get if you installed Ubuntu on a full desktop machine.
