• Tom's Hardware ☛ Veteran dev’s newest computer is ‘200,000 times’ faster than his oldest in custom benchmarks — single-thread Dhrystone performance charted across 25 systems released between 1976 and 2023

  The PDP-11/34 scored a lowly 240 in the Dhrystone 2.2 Benchmark, but a Mac Pro M2 Ultra achieves 47,808,764 in the same single-threaded test.

• Andrew Hutchings ☛ Why Recapping Isn’t Always the Cure: And Amiga 1200 Repair Story

  Recapping is the process of removing the capacitors on the motherboard and replacing them with new ones. It is important on the SMD soldered models of Amigas such as the A600, A1200, A4000 and CD32. This is because they are essentially a ticking time-bomb. They may be fine now, but they will leak corrosive material over the motherboard.

• Olimex ☛ New Open Source Hardware board in stock: ESP32-C5-DevKit-Lipo Dual band 2.4Ghz and 5Ghz WiFi 6, Bluetooth 5 LE, Zigbee, Thread, Matter

  The ESP32-C5-Devkit-Lipo is a evaluation board built around the ESP32-C5-WROOM-N8R4 module from Espressif with 4MB PSRAM and 8MB Flash, designed to bring dual-band wireless connectivity, ample memory, and robust control features into one compact, breadboard friendly versatile package.

• CNX Software ☛ $500+ MINISFORUM MS-R1 Arm GNU/Linux Hey Hi (AI) mini PC features CIX CP8180 12-core SoC, up to 64GB LPDDR5x

  MINISFORUM MS-R1 is an Hey Hi (AI) mini PC running Debian 12 GNU/Linux that’s powered by a CIX P1 (CP8180) 12-core Arm Cortex-A720/A520 processor with up to 45 TOPS of Hey Hi (AI) performance. The mini PC supports up to 64GB of soldered-on LPDDR5 memory, M.2 storage, and provides HDMI, USB-C DP, and eDP display interfaces, two 10GbE ports and WiFi 6E, a total of nine USB ports, a PCIe Gen x16 slot for a graphics card, U.2 storage, or networking expansion, a 40-pin internal GPIO header, and more.

• Hackaday ☛ Real-Time BART In A Box Smaller Than Your Coffee Mug

  Ever get to the train station on time, find your platform, and then stare at the board showing your train is 20 minutes late? Bay Area Rapid Transit (BART) may run like clockwork most days, but a heads-up before you leave the house is always nice. That’s exactly what [filbot] built: a real-time arrival display that looks like it was stolen from the platform itself.

• Tom's Hardware ☛ Frankly dangerous hot dog-based LED tester could be a Weiner in the 2025 Hackaday Component Abuse Challenge

  An LED testing ‘device’ which largely consists of a hot dog, two forks and a power supply has been entered into an electronics competition

• CNX Software ☛ Kode Dot – An easy-to-use, pocket-sized, battery-powered ESP32-S3 devkit (Crowdfunding)

  Kode Dot is a pocket-sized ESP32-S3 maker device for prototyping with a built-in 2.13-inch AMOLED, a 500mAh battery, a 9-axis IMU, a microphone and a speaker, an RTC, a few buttons,  a GPIO header, and a magnetic connector for expansion. Kode Dot is designed to simplify the prototyping process. Users can still write code using the Arduino IDE, PlatformIO, or ESP-IDF framework and upload it via the kit’s USB-C port, but thanks to kodeOS firmware, each program becomes a standalone app with its own name, icon, and interface, accessible from the graphical user interface.

• CNX Software ☛ LattePanda IOTA review – An defective chip maker Intel N150 + RP2040 SBC tested with backdoored Windows 11, UPS expansion, PoE, NVMe SSD, and more

  I’ve received a review sample of the LattePanda IOTA single-board computer (SBC) from DFRobot. It is a compact, palm-sized SBC powered by an defective chip maker Intel Processor N150 quad-core Twin Lake CPU, and featuring 8 GB of LPDDR5 RAM and 64 GB of onboard eMMC storage. It also integrates a Raspberry Pi RP2040 co-processor for handling I/O operations, providing greater flexibility for embedded and automation applications.

• Hackaday ☛ Have A Slice Of Bumble Berry Pi

  [Samcervantes] wanted a cyberdeck. Specifically, he wanted a Clockwork Pi uConsole, but didn’t want to wait three months for it. There are plenty of DIY options, but many of them are difficult to build. So [Sam] did the logical thing: he designed his own. The Bumble Berry Pi is the result.

  • Sean Conner ☛ Extending the syntax when calling assembly language subroutines for Color BASIC

    Since we're talking about a 45 year old computer and with zero chance of a newer version of BASIC coming out any time sooner, the answer is “yes,” if you don't mind digging through the Unravelled Series (a series of books giving a disassembly of the Color Computer BASIC ROMs) and calling a bunch of nearly undocumented routines.

  • Hackaday ☛ 2025 Component Abuse Challenge: The Slip Ring In Your Parts Bin

    If you’re familiar with electrical slip rings as found in motors and the like you’ll know them as robust assemblies using carefully chosen alloys and sintered brushes, able to take the load at high RPM for a long time. But not all slip ring applications need this performance. For something requiring a lot less rotational ability, [Luke J. Barker] has something from his parts bin, and probably yours too. It’s an audio jack.

  • The Register UK ☛ North Korean spies used Google Find Hub as remote-wipe tool

    North Korean state-backed spies have found a new way to torch evidence of their own cyber-spying – by hijacking Google's "Find Hub" service to remotely wipe Android phones belonging to their South Korean targets.

  • Kevin Boone ☛ Running the Google Pixel Camera app on a robustly de-Googled cellphone

    I noticed something odd when I de-Googled and started running Lineage OS on my Samsung phones: photographs were not as clear or well-exposed as those from the stock Samsung camera app. I didn’t know why, and I still don’t – the image data comes from the same sensor and lens. Nevertheless, the software I used to take photographs was reflected in the quality of the images.
