PicoIDE – An open-source hardware IDE/ATAPI drive emulator for vintage computers (Crowdfunding)

PicoIDE is an open-source hardware IDE/ATAPI drive emulator based on a Raspberry Pi RP2350 board and designed to replace hard drives and CD-ROM drives in vintage computers with microSD card storage. Users don’t need to burn optical discs or deal with old IDE hard drives with bad blocks, and instead, they can simply put their disk images on a microSD card and swap between them as needed. Two versions are offered, namely the PicoIDE Base featuring full IDE/ATAPI emulation in a standard 3.5-inch enclosure with a microSD card slot, and CD audio output, and the PicoIDE Deluxe, adding an ESP32-C3-based front panel with WiFi connectivity, an OLED, and navigation buttons. PicoIDE specifications: MCU – Raspberry Pi RP2350 microcontroller CPU 2x Arm Cortex-M33 cores @ 150 MHz 2x Hazard3 RISC-V cores @ 150 MHz Up to two cores can be used at any time (configured at boot) Memory – 520KB SRAM […]

Witty Pi 5 HAT+ – A Raspberry Pi RP2350-based power scheduler with time, temperature, and voltage-based triggers

Designed by UUGear, the Witty Pi 5 HAT+ is a power scheduler board for Raspberry Pi that features an RP2350 MCU for running scheduling logic. It includes a high-precision RTC with voltage and temperature monitoring for automated power on/off, making it suitable for solar-powered projects, environmental monitors, and industrial controllers that require scheduled power on/off control to extend battery life. The board follows the Raspberry Pi HAT+ specification and accepts power from either a 6V–30V DC input through a terminal block or a 5V USB-C supply, while delivering up to 5A to the Raspberry Pi and connected peripherals. It can also work as a simple UPS, thanks to its dual “ideal diode” configuration with an automatic switchover feature in case of power failure. Other hardware features include an onboard DC/DC converter, an ID EEPROM for HAT+ identification, a CR2032 RTC battery, and a wide –30°C to +80°C operating temperature range. […]
