PicoROM – Raspberry Pi Pico ROM Emulator for Amstrad CPC
Sep 25,2026
This is just sharing the project from https://github.com/mattcallow/CPC_PICOROM — all design credit goes to the original author, Matt Callow. PicoROM plugs into the 50-way expansion port of an Amstrad CPC and uses a Raspberry Pi Pico to emulate the lower ROM and up to 12 upper ROMs from RAM.Plugged into a PC, the Pico appears as a USB flash drive, so you just copy ROM files and simple config files onto it. A companion ROM adds RSX commands such as |ROMSET, |ROMIN and |PDIR to switch ROM sets fro...

Case Study: Designing a Raspberry Pi HAT for Industrial Sensor Data Collection
kumari Sep 18,2026
They had a fleet of Raspberry Pi units deployed across factory floors, each one collecting readings from vibration, temperature, and current sensors. The setup worked, but the wiring was a mess. Every Pi had a breadboard or a bundle of jumper wires hanging off the GPIO header. Connections worked loose. Units failed in the field. Maintenance techs spent more time reseating wires than actually fixing anything.They wanted a proper HAT — a Hardware Attached on Top board that would sit cleanly on the...

Captain Reef's Prophecies
Sep 16,2026
What's this project about?Captain Reef is a Zoltar-style fortune-telling fish. You ask her a question, she thinks it over (with some dramatic flair), and prints out a personalized fortune on a receipt. Under the hood she's running a Raspberry Pi 5, an ESP32, custom PCBs, an E-Ink display, and a thermal printer, all wrapped in a 3D-printed and CNC-cut fish-themed enclosure.Why did I build it?Growing up, I was obsessed with the Zoltar machine at Cedar Point. Something about a mechanical fortune t...

ZX Spectrum RGBI to VGA & HDMI Adapter (Raspberry Pi Pico)
Sep 14,2026
This is simply a reshare of an existing open-source project — all design credit belongs to AlexEkb, and the original lives at https://github.com/AlexEkb4ever/ZX_RGBI2VGA-HDMI under GPL-3.0. Nothing in the design has been altered; the files here have only been reorganised, documented, and prepared for fabrication.The board captures the ZX Spectrum's four digital colour signals (R, G, B and the brightness bit) directly from the machine's ULA or logic, rather than digitising an analogue output the ...

Trident MCU Sandbox
Kumar Sep 12,2026
Trident MCU Sandbox This board is a combined version of Arduino Nano, ESP32 32E, Raspberry Pi Pico micro-controllers.Also has a battery holder and a battery protection plus charging circuit. Although you can charge it through a Mobile Charger BUT it is generally recomended to charge it through a Laptop. This board also features an adjustable Micro SD card slot, means you can connect the Micro SD card to any of these micro controller through jumper wires. Also have three OLEDs 1 for each mirocont...

QLpicoVGA — Sinclair QL to VGA Video Interface with a Raspberry Pi Pico
Sep 11,2026
This is a share of holmatic's open-source QLpicoVGA project — the original lives at https://github.com/holmatic/video_if_ql_vga and all credit goes to its author. Finding a monitor that displays a Sinclair QL properly is a real problem today, since the QL's video output is non-standard and most displays crop the 512-pixel-wide screen. This interface samples the QL's RGB and composite sync signals at 32 MS/s and re-renders them as a pseudo-XGA 1024×768 VGA signal, mapping each QL pixel to a 2×3 b...

Giving an HP N40L MicroServer a New Raspberry Pi CM5 Motherboard
Sep 11,2026
Embedded Project Video This is an HP N40L MicroServer. After nearly 15 years its original processor, USB 2.0 connectivity and ageing hardware are becoming increasingly limiting.So rather than replace the server, I decided to replace the motherboard.I started with the Raspberry Pi Compute Module 5 IO Board reference design and turned it into a completely custom motherboard designedspecifically around the HP N40L chassis.PCBWay sponsored the manufacturing for this project by providing the PCB, ass...

Case Study: Building the Raspberry Pi RC522 RFID HAT — An Open-Source RFID Expansion Board
kumari Aug 31,2026
The Problem: RC522 Modules Are a PainThe RC522 is a solid, inexpensive MFRC522-based RFID reader IC. It's been around forever, it's well-documented, and it works. But the breakout boards you find online have a few problems:- They're 5V logic, not 3.3V. The RC522 chip itself runs at 3.3V, but many breakout boards have level-shifting issues that cause intermittent SPI communication failures.- They require manual wiring. 7–8 jumper wires to the Pi's GPIO header. Fine for a one-off prototype, terrib...
