Raspberry Pi Rescues Old Wi-Fi Radios: Open-Source HLS-to-MP3 Converter Hits v2.3 Plenty of perfectly good internet radios, including many built on Frontier Silicon modules, can play a plain MP3 stream over HTTP but have no idea what to do with an HLS (.m3u8) playlist. When a favourite station moves to HLS, the radio simply goes quiet. Clifford Farrugia built HLS Radio Converter to fix that. It runs on a Raspberry Pi on your home network, pulls the HLS stream, and hands the… |

Raspberry Pi 4 Runs a Real Apollo Guidance Computer Inside This 1:1 3D-Printed DSKY Replica The DSKY was the keypad and display Apollo astronauts used to talk to the Apollo Guidance Computer, and Michael Newton has rebuilt one at 1:1 scale from archived NASA and MIT drawings. Inside the 3D-printed case, a Raspberry Pi 4B runs yaAGC, the Virtual AGC project's emulator of the original computer, so the keypad, the green VERB/NOUN/PROG readout and the warning lights all behave as they… |

A Single 1GB DDR4 Chip Now Costs More Than an Entire 1GB Raspberry Pi 5 A single mainstream DDR4 chip now costs more on the spot market than a whole entry-level Raspberry Pi. In its latest memory spot price report, TrendForce put the average spot price of a DDR4 1Gx8 3200 MT/s chip (8 Gb, or 1 GB) at US$46.357 for the week of October 20, up 0.84%. Raspberry Pi still lists the 1GB Raspberry Pi 5 at US$45. If you design boards or buy SBCs, memory now decides your… |

No PC, No Cables: This Raspberry Pi 4 Beams an FPV Drone Sim Straight Into Your Analog Goggles Developer juricabi has built StickTime Pi, an open-source project that turns a Raspberry Pi 4 into a "virtual quad". The Pi runs the StickTime FPV simulator and pushes the picture through a 5.8 GHz video transmitter (VTX) wired to its AV jack, so the game shows up in the same analog goggles you use for real flights. You fly it with your own radio over the ExpressLRS/Crossfire WiFi joystick,… |

Building a Private AI Media Library With Raspberry Pi 5 for Smart Photo Search and Auto Backups to Two USB Drives Alonso Vidales has built Off The Cloud, an open-source Raspberry Pi 5 project that lets users store, search and share family photos without relying on a traditional cloud photo and video -storage service. Instead of sending photos and videos to an external server for storage and AI analysis, the system keeps them on a device at home. It automatically backs up full-resolution photos and videos… |

Turning a Backyard into an 8-Foot Satellite Ground Station with Raspberry Pi to Capture Weather Images from Space Cranktown City has built a DIY satellite ground station that uses an 8-foot satellite dish to follow satellites as they move across the sky and receive the radio signals they transmit. Unlike a manually operated dish, this system can calculate a satellite's position and automatically move the dish to follow it. One of the project's biggest achievements is receiving full-disk weather images… |

iPod Lives Again: Open-Source RPi Motherboard Adds Wi-Fi, Bluetooth, USB-C, 2TB Storage, Spotify, Apple Music & More For nearly two decades, vintage Apple iPods have been dormant in desk drawers, victims of dead batteries, obsolete charging cables, and retired iTunes libraries. Now, a London-based hardware startup called Certain Things is changing the narrative with Sprout, an open-source replacement motherboard that drags early-2000s music players kicking and screaming into the modern wireless era. Rather… |

This Raspberry Pi Zero 2 W Runs a Virtual Viking Dragon That Feeds on Nearby Wi-Fi and Bluetooth signals What if your virtual pet could find food from the Wi-Fi and Bluetooth signals around you? Meet Harald, a virtual dragon created by a Raspberry Pi enthusiast. Built using a Raspberry Pi Zero 2 W and a Waveshare V4 e-paper display, Harald treats nearby Wi-Fi networks and Bluetooth devices as food. Discovering new devices makes the dragon happier, turning everyday wireless activity into a virtual… |

Ball-Balancing Robot Uses a Mirror to Stay Compact; Pi Handles Vision, Leaves Motor Step Timing to 3 RP2040 Chips MirrorBallBot, an open-source ball-balancing robot from a maker using the GitHub handle AndreaFavero71, looks at its platform through a mirror rather than from above. The camera sits to the side and points at a mirror inclined at 27 degrees beneath the platform. The author says that, for the same camera and robot height, this widens the field of view by 58%, which allows a larger platform… |

RP2350 Microcontroller Drives Full 1080p HDMI With No Framebuffer Using Scanline Technique Aaron Gayle’s TV‑Top Kiosk project shows how to squeeze a full 1920×1080 HDMI signal out of a RP2350 microcontroller, which is seen in the popular Raspberry Pi RP2350 development board. To reach 1080p, he overclocked the RP2350 to 372 MHz and used its faster peripherals to generate a DVI/HDMI signal at up to 30 Hz in 24‑bit color. The result is a tiny, low‑cost “console” stick, something like… |

Maker Turns a Normal IR TV Remote into a Functional Keyboard Using I2C for His Handheld PC In his DIY electronics project, maker Mirza Makes transformed an ordinary TV remote into a fully functional keyboard for his portable computer. The idea was to give it a soft keyboard, the kind of ones seen in TV remotes. The build centers around a high-performance Raspberry Pi 5 paired with a compact Elecrow 5-inch TFT touchscreen display to provide a… |

He Trained a 2.9M-Parameter AI Image Generation Model, Ran It on a $1 RP2350 Chip and Open-Sourced the Project Generative AI image models usually require powerful processors and large amounts of memory, but a new project demonstrates that image generation can be pushed onto a small microcontroller. Tim, from Tim’s Blog, has implemented a generative AI image model on the RP2350, the microcontroller used in the Raspberry Pi Pico 2. Running on a Waveshare RP2350-Plus board, the system can generate 128×128… |
