Hackaday ☛ There’s Nothing Mini About This Mini Hasselblad-Style Camera’s Sensor
When someone hacks together a digital camera with a Raspberry Pi, the limiting factor for serious photography is usually the sensor. No offense to the fine folks at the foundation, but even the “HQ” camera, while very good, isn’t quite professional grade. That’s why when photographer [Malcolm Wilson] put together this “Mini Hasselblad” style camera, he hacked in a 1″ sensor.

CNX Software ☛ Pi Zero-sized Radxa Cubie A7Z SBC features Allwinner A733 Cortex-A76/A55 SoC, up to 16GB RAM, WiFi 6
Radxa Cubie A7Z is the little brother of the Cubie A7A SBC, still based on a powerful Allwinner A733 octa-core Arm Cortex-A76/A55 SoC, but offered in a more compact form factor inspired by the Raspberry Pi Zero. The compact single board computer also comes with up to 16GB RAM, a microSD card slot, optional UFS flash, micro HDMI and USB-C DisplayPort video output, a WiFi 6 and Bluetooth 5.x wireless module, a 4-lane MIPI CSI camera connector, a PCIe Gen3 FPC connector (at first for Pi Zero-sized board), and a 40-pin GPIO header.

CNX Software ☛ Waveshare RP2350-Matrix board features 8×8 WS2812 RGB LED matrix, 6-axis IMU, Dout pin for more LEDs
Waveshare’s RP2350-Matrix is a Raspberry Pi RP2350A-powered LED matrix board featuring 64 RGB LEDs (8×8 RGB matrix), a built-in 6-axis IMU, and a Dout pin in case the user needs even more LEDs. The RP2350-Matrix also includes 25 GPIOs along with 12 PIO state machines for custom peripheral support, an on-chip temperature sensor, accurate hardware timers, and support for low-power sleep and dormant modes. It comes with a USB Type-C port for power and programming via USB 1.1 device/host, and an onboard 800mA LDO regulator for stable power delivery. These features make this board suitable for motion sensing and visual feedback.

Hackaday ☛ Debugging The Instant Macropad
Last time, I showed you how to throw together a few modules and make a working macropad that could act like a keyboard or a mouse. My prototype was very simple, so there wasn’t much to debug. But what happens if you want to do something more complex? In this installment, I’ll show you how to add the obligatory blinking LED and, just to make it interesting, a custom macro key.

Jeff Geerling ☛ Reverse Engineering ALL the Raspberry Pis
Earlier this month I covered Jonathan Clark's effort to reverse-engineer the Pi Zero 2 W, and just yesterday, I discovered TubeTime reverse-engineered the Compute Module 5.

Arduino ☛ An Arduino Opta micro PLC safely controls this massive solar panel lift
The dividing line between microcontroller development board and programmable logic controller (PLC) use cases has become increasingly blurred in recent years, as today’s Arduino hardware is very robust and reliable. But there are still situations in which peace of mind and regulatory standards support the use of a PLC, which is why we launched the Arduino Opta line of micro PLCs. Rob Broomfield, AKA “Metal Fab Man,” took advantage of an Opta to build a set of massive motorized solar panel lifts for a customer.

Raspberry Pi ☛ Picocomputer 6502
The fact that anyone can build it themselves is testament to some brilliant design work by Rumbledethumps. And, of course, we’re delighted to see a pair of Raspberry Pi Pico microcontroller boards as part of the build.

Raspberry Pi ☛ Network mapper
Like many projects, this one began life not out of a need, but out of finding a stash of cool components and wanting to do something with them. In this case, the component haul was a tray of MD0657C2-R displays from a surplus component shop. Add a few MAX6952 chips to drive the displays, and six Raspberry Pi Pico Ws, and you’ve got the guts of a unique visual display that feels like it came from the set of Superman 3.

Hackaday ☛ Pi Port Protection PCB
We’re used to interfaces such as I2C and one-wire as easy ways to hook up sensors and other peripherals to microcontrollers. While they’re fine within the confines of a small project, they do have a few limitations. [Vinnie] ran straight into those limitations while using a Raspberry Pi with agricultural sensors. The interfaces needed to work over long cable runs, and to be protected from ESD due to lightning strikes. The solution? A custom Pi interface board packing differential drivers and protection circuits aplenty.

CNX Software ☛ LILYGO T-Circle-S3 – An ESP32-S3 devkit with 0.75-inch circular touch display, microphone and speaker
The LILYGO T-Circle-S3 is a circular touch display development board built around the ESP32-S3 MCU and designed for smart gadgets, IoT devices, and wearable applications. The board integrates Wi-Fi 4, Bluetooth 5.0, a MEMS microphone, a 3W Class-D audio amplifier with speaker support, an RGB LED, six rear GPIO pins, a Qwiic interface, and USB-C for charging. The board is very similar to the Waveshare RP2350-LCD-1.28, with its round display design, but it does not support wireless connectivity and audio.

Jan Lukas Else ☛ Is it a bad buy?
I was able to completely replicate my current setup, which uses a dedicated GL.iNet Beryl AX running vanilla OpenWRT. I even replaced my router with it for a few hours to test it in a real-world “production use” scenario. Unfortunately, I somehow experienced some weird latency issues from time to time. I ran countless speed tests and tried different network adapter settings in Proxmox (using network bridges, mapped PCI devices, and direct PCI device passthrough) as well as different CPU and memory settings. None of these changes helped much. The test results weren’t bad, but they were worse than the results from the Beryl AX. Maybe with a more stable internet connection and not via 5G, I wouldn’t have even noticed, but SQM with CAKE is critical for a good internet experience in my setup.
