This Raspberry Pi price tracker is shutting down next month because retailers blocked its bot

RPI Locator, a popular Raspberry Pi price tracking site, is shutting down in July after retailers began blocking its web scraping bots. The site's owner tried various workarounds but none lasted more than a few days or weeks. With Raspberry Pi prices having risen significantly, the closure makes finding good deals harder for hobbyists.

This ASUS Vivobook S16 with an AMD Ryzen AI 7 CPU hits its lowest price ever, but you'll need to act fast before Prime Day ends

The ASUS Vivobook S16 is on sale during Amazon Prime Day 2026 at its lowest price ever — $880 (down from $1,095). It features an AMD Ryzen AI 7 350 CPU, a 16-inch 3K OLED display at 120Hz, 16GB RAM, 1TB storage, and a 75Wh battery rated for up to 14 hours. The laptop is thin and light at 0.55 inches and 3.31 lbs, with integrated graphics rather than a discrete GPU. It includes a solid port selection: HDMI, two USB-C, microSD, audio jack, and two USB-A ports.

Review: Gamrombo PS5 controller - including Linux set up

A hands-on review of the Gamrombo PS5 controller, a ~£40 third-party alternative to the official DualSense. It works out of the box on Linux via USB-C and Bluetooth, registers as a Sony DualSense, and supports touchpad gestures, vibration, speaker, and 3.5mm audio. Extras include programmable macro buttons and a turbo function. Downsides include no microphone, Windows-only firmware updater distributed via WeTransfer, no charging dock support, and a slightly cheaper feel compared to the official controller.

Top SA computer scientist on IBM’s chip breakthrough

IBM has announced a sub-1nm (0.7nm / 7-angstrom) chip design that packs nearly 100 billion transistors onto a fingernail-sized surface — roughly double the density of its 2021 2nm chip — with up to 50% more performance or 70% better energy efficiency. The key innovation is a 3D 'nanostack' architecture that stacks transistors vertically rather than shrinking them further. A South African quantum computing expert, Francesco Petruccione of NITheCS and Stellenbosch University, calls it a genuine engineering milestone and highlights implications for AI workloads, data centre energy costs, and on-device AI. IBM also reports a ~40% improvement in on-chip SRAM, easing the memory bottleneck for AI inference. Commercial production is estimated within five years, though significant manufacturing challenges remain.

$449 CHUWI UniBook 14-inch laptop is powered by an Intel Core 3 304 Wildcat Lake processor

CHUWI has opened pre-orders for the UniBook, a 14-inch laptop priced at $449 (regular $499) powered by Intel's new Core 3 304 'Wildcat Lake' processor. The penta-core SoC is built on Intel 18A and features an Xe3 GPU and 15 TOPS NPU. The laptop ships with 8GB LPDDR5 RAM, a 256GB NVMe SSD, a 1920×1200 IPS display, Wi-Fi 6, and a 53.38Wh battery rated for up to 13 hours. Early PassMark benchmarks suggest performance comparable to Apple's A18 Pro. Shipping is expected to start July 20, 2026, making this one of the first consumer Wildcat Lake laptops available for purchase.

Firefly AIBOX-9075 Edge AI box features Qualcomm IQ-9075 SoC with 200 TOPS NPU, 36GB LPDDR5

Firefly has launched the AIBOX-9075, an industrial Edge AI box powered by the Qualcomm DragonWing IQ-9075 SoC. It delivers up to 200 TOPS of AI performance via a Hexagon Tensor Processor NPU, paired with 36GB LPDDR5 ECC memory and 128GB UFS 2.2 storage. The device targets edge AI workloads including private LLM deployment, robotics, and computer vision. It supports popular AI frameworks (TensorFlow, PyTorch, ONNX) and LLMs such as DeepSeek-R1, Llama, and Gemma, achieving up to 22 tokens/s with Llama2-7B. Connectivity includes dual 2.5GbE with TSN, optional Wi-Fi 6, 4G/5G, and 8x GMSL2 camera inputs. The rugged aluminum enclosure operates from -40°C to 85°C. It runs Ubuntu and Yocto Linux and is priced at $1,239 from the Firefly store.
