Visualize radio signals with Raspberry Pi 5-based QuadRF 4x4 MIMO software-defined radio tile (Crowdfunding)

RP2350B bells&whistles development board features on-board RP2040 debugger, HDMI, and microSD card slot

Bảng phát triển RP2350B Bells&Whistles tích hợp sẵn bộ gỡ lỗi RP2040 (Picoprobe), cổng HDMI (qua PicoDVI), khe cắm thẻ microSD, PSRAM 8MB tùy chọn, flash SPI 4MB, 46 chân GPIO và hai cổng USB-C. Bo mạch hỗ trợ nguồn mở (KiCad, sơ đồ trên GitHub) với giá 29,95 USD trên Tindie.

Lập trình viên muốn phát triển ứng dụng trên RP2040 nhưng gặp khó khăn với việc debug và mở rộng hệ thống cần tìm hiểu cách tích hợp RP2350B để tiết kiệm chi phí và tăng hiệu năng với các tính năng như debug built-in, HDMI, và lưu trữ MicroSD.

I turned an old Android phone into a home server, and it outperformed my Raspberry Pi

An old Android phone running Termux can serve as a capable home server that outperforms a Raspberry Pi in several ways. The phone's UFS storage is significantly faster than microSD cards commonly used in Pi setups, and even older flagship Android chips tend to be more powerful than typical SBC processors. Setup involves installing Termux, disabling battery optimization, and assigning a static IP. Services like Jellyfin, Tailscale, ad-blockers, file servers, and lightweight databases run well. The main caveat is battery longevity when kept plugged in constantly, which a smart plug can help manage.

My 3D printer pays for itself every time I skip buying a PC accessory

A home lab enthusiast shares how 3D printing has replaced buying small PC accessories. By printing custom cable organizers, headphone stands, GPU anti-sag risers, Raspberry Pi cases, and ESP32 enclosures, they get perfectly sized parts for under $5 that outperform cheap ready-made alternatives. The post covers practical use cases including PETG filament for heat-resistant functional parts and plans for future projects like DIY headphones and an open-air E-ATX server case.

Network-wide ad blocking with a Raspberry Pi Zero is easier than you think, but the Wi-Fi problem is real

Running Pi-hole on a Raspberry Pi Zero is one of the easiest ways to set up network-wide ad blocking at home. The board is cheap, low-power, and requires minimal setup — flash an image, install Pi-hole, and point your router's DNS at it. However, the Pi Zero lacks built-in Ethernet, meaning DNS runs over Wi-Fi unless you add a USB Ethernet dongle and adapter, which undermines the device's simplicity and reliability. MicroSD storage is another long-term concern. The Pi Zero is a great entry point for learning DNS filtering, but once it becomes core household infrastructure, upgrading to a Pi 4, mini PC, or LXC container on existing hardware offers better reliability, real Ethernet, and more robust storage.

Raspberry Pi Locator Website To Shut Down In July

Rpilocator.com, a popular site tracking Raspberry Pi stock and pricing across online retailers, is shutting down in July 2026. The main reason is that the site's indexing bot has been blocked by most shopping sites, likely due to anti-scraping measures aimed at AI bots. The site still serves around 11,000 monthly users but the effort to maintain workarounds became unsustainable. The closure also reflects a broader shift in the single-board computer landscape: the chip shortage era that made such a tracker essential has passed, replaced by concerns over rising memory prices pushing Raspberry Pi boards into luxury price territory.

Vaultwarden has been running on a Raspberry Pi Zero in a drawer for a year, and it's the most underrated thing I host

Running Vaultwarden on a Raspberry Pi Zero 2W as a self-hosted password manager is a low-cost, low-power alternative to cloud-based services like LastPass. The setup uses DietPi (skipping Docker to conserve resources), the Bitwarden browser extension pointed at the local server, and Tailscale for secure remote access. The Pi Zero 2W draws under a watt, can run off a power bank, and handles Vaultwarden's lightweight workload comfortably. The result is full Bitwarden feature parity — password generator, 2FA, vaults, autofill — with no monthly subscription and no third-party data exposure.
