CNX Software ☛ Elecrow ESP32-S3 rotary displays combine round IPS touchscreen, knob, and press input
Elecrow has added two new ESP32-S3-powered rotary displays to its CrowPanel Advance lineup, which come in 1.28-inch (240×240) and 2.1-inch (480×480) sizes, and feature a round IPS screen with rotary, touch, and press input. Both rotary displays feature IPS capacitive touchscreens, rotary input with a smooth feel, knob-press operation, ambient lighting, USB-C (5V) power, and expansion capabilities via UART, I²C, and FPC connectors.

Hackaday ☛ A Ruggedized Raspberry Pi For Sailors
Nautical navigation has a long history of innovation, from the compass and chronometer to today’s computer-driven autopilot systems. That said, the poor compatibility of electronics with saltwater has consequently created a need for rugged, waterproof computers, a category to which [Matti Airas] of Hat Labs has contributed with the open-source HALPI2.

Linux Gizmos ☛ Shuttle Fanless Mini Edge PC with Up to 40 TOPS AI Performance
The SPCNV03 is built on the NVIDIA Jetson Orin Nano module, available in two configurations. The 8GB version provides 40 TOPS of AI performance with 1024 CUDA cores and 32 Tensor cores at 7 to 15 watts, while the 4GB version offers 20 TOPS with 512 CUDA cores and 16 Tensor cores at 7 to 10 watts. Both versions integrate a six-core Arm Cortex-A78AE CPU running at 1.5GHz and a GPU frequency of 625 MHz.

Hackaday ☛ “Simplest” Oscilloscope Is A Cunning Vector Display
Superlatives are tricky things. [mircemk]’s guide “How to make Simplest ever Oscilloscope Clock” falls into that category. It’s that word, simplest. Certainly, this is an oscilloscope clock, and a nice one. But is it simple?

CNX Software ☛ Olimex ESP32-C5-EVB – A dual-band WiFi 6 IoT board with relays, opto-isolated inputs, LiPo battery support
Olimex ESP32-C5-EVB is an evaluation board built around Espressif’s ESP32-C5-WROOM-N8R4 module with dual-band (2.4/5.0GHz) WiFi 6, Bluetooth 5.0 LE, and 802.15.4 (Zigbee/Thread/Matter) wireless connectivity, 8MB flash, and 4MB PSRAM. The board integrates two relays rated 250V/10A, two opto-isolated inputs, and a LiPo UPS charger and step-up converter. Other features include USB-C ports, a UEXT connector for expansion, and two buttons.

Hackaday ☛ Computer Has One Instruction, Many Transistors
There’s always some debate around what style of architecture is best for certain computing applications, with some on the RISC side citing performance per watt and some on the CISC side citing performance per line of code. But when looking at instruction sets it’s actually possible to eliminate every instruction except one and still have a working, Turing-complete computer. This instruction is called subleq or “subtract and branch if less-than or equal to zero“. [Michael] has built a computer that does this out of discrete components from scratch.

Hackaday ☛ Regretfully: $3,000 Worth Of Raspberry Pi Boards
We feel for [Jeff Geerling]. He spent a lot of effort building an AI cluster out of Raspberry PI boards and $3,000 later, he’s a bit regretful. As you can see in the video below, it is a neat build. As Jeff points out, it is relatively low power and dense. But dollar for dollar, it isn’t much of a supercomputer.
