Optocam Zero – A Raspberry Pi Zero 2 W -based DIY digital camera

Inspired by Kodak Charmera and similar toy cameras, the Optocam Zero is a Raspberry Pi Zero 2 W-based DIY digital camera made of off-the-shelf components and 3D-printed parts. It connects the Pi Zero 2 W SBC with a Raspberry Pi Camera Module 3, a 1.3-inch LCD, a 14500 Li-Ion battery holder, and other components. The camera supports autofocus, eight photo filters, USB-C charging, and lasts 70 to 80 minutes on a charge. Optocam Zero camera key features: Based on Raspberry Pi Zero 2 W SBC Display 1.3-inch LCD with 240 x 240 resolution 15–20 FPS camera preview on the screen. Screen dimming when inactive to preserve battery Camera features 2592 x 2592 JPEG image capture. GIF recording and playback support. Autofocus support 8 photo filters included. Misc Image transfer through custom hotspot interface. Fully 3D printed case parts 3D printable TPU protective sleeve and lanyard design is available. 22-second boot

Convert old IR remote controls into presentation clickers using an RP2040 USB board and open-source TTVKTR firmware

Brisk4t's "Tossed The TV — Kept The Remote" (TTVKTR) is an open-source firmware project for Raspberry Pi RP2040 USB boards that aims to reduce electronics waste by converting old IR remote controls into presentation clickers. Most Raspberry Pi RP2040 boards with USB ports should work, but the project highlights the Waveshare RP2040-Zero combined with a standard 38 kHz infrared receiver due to its small size and low price ($4-5). The project also relies on the built-in RGB LED for layer color feedback. That's about it for the hardware. It just required some basic soldering of the IR receiver to GPIO 28 (OUT), 5V or 3.3V, and GND pins. Nothing too hard. The WS2812 RGB LED is already connected to GPIO 16. I tried to look for RP2040 USB boards with a built-in IR receiver, but I could not find any.   The firmware receives IR codes from a standard 38

Waveshare RP2350B-Plus-W – A Raspberry Pi Pico 2 W-sized board with 41 GPIOs, 16MB flash, USB-C port

Waveshare RP2350B-Plus-W is a development board that follows the Raspberry Pi Pico 2 W form factor, but offers 41 GPIOs thanks to the RP2350B MCU, integrates 16 MB of flash, and includes a USB-C port. So, in several ways, it's an upgrade over the RP2350A-based official board, which offers only 26 GPIOs via two 13-pin GPIO headers, 4MB of flash, and a micro USB port. Since it's the same size, where do the extra GPIOs come from? Answer: The company simply added 15 pads to the bottom of the board, not quite as convenient since it's requires soldering, but it does the job.   Waveshare RP2350B-Plus-W specifications: SoC – Raspberry Pi RP2350B CPU Dual-core Arm Cortex-M33 @ 150 MHz with Arm Trustzone Dual-core RISC-V Hazard3 @ 150 MHz Only two cores can be used at any given time Memory – 520 KB on-chip SRAM Package – QFN-80 Memory - Footprint
