Battery powered MEGO Portable Power Supply fits into Breadboards

Breadboard power supplies like MB102 have been around for years, and some even designed a variable power supply for breadboards, but EVO-IN-MOTION MEGO looks much neater as a fully enclosed power supply, 4 to 24V output, fitted with a LiPo battery, and a display to show current voltage. MEGO enabled on-the-go breadboard projects without any cables for the power supply. Just connect the power supply, and you’re good to go with power delivered from the built-in battery. MEGO power supply specifications: Output Voltage – 4-24V DC Maximum Power – 6W Safety – Overload protection; short circuit protection Typical Power Efficiency – 88% Voltage Display Accuracy – <1% Ripple Voltage – <1% Load Regulation – 270mV Battery – 7.4Whs (2,000 mAh @ 3.7V) Misc – Power button;, adjust knob for output voltage; low battery and charging LEDs Dimensions – 73 x 59 x 32 mm Weight – 100 grams Temperature Range […]

Alipay Dragonfly F1 PoS Enables Payments with Face Recognition

We’re being told the traditional way of paying for purchases – cash – is going away, so we’ll soon have to rely exclusively on electronics payment means such as debit cards, credit cards, contactless stored value smart cards, smartphones, our own face, etc… Wait? I could pay by just showing up my face? Apparently yes, as Alipay recently installed 12 Dragonfly POS (Point-of-Sales) devices with biometric technology at Hong Kong airport. The systems started operating at the airport on April 2nd, but similar devices were allegedly deployed in more than 300 cities in mainland China previously. I’m not entirely sure of the exact model operating at Hong Kong airport, but a quick web search reveals Alipay Dragonfly F1 matches the description. Hardware specifications: Processor – Quad-core Arm Cortex A53 processor @ 1.3GHz System Memory – 2GB RAM Storage – 8GB FLASH Display – 10.1″ TFT touch screen display with 1280×800 […]

Panfrost is an Open Source Driver for Arm Mali Midgard GPUs

Getting GPU drivers to work on Linux with Arm SoCs was really a struggle a few years ago due to close-sources binary blobs that required all bugs to be fixed by a single team. But in recent years we’ve seen good progress with open source mobile GPU drivers including Freedreno for Adreno GPUs, and Etnaviv for Vivante GPUs. Arm Mali also got its own open source Lima driver worked on for many years but only for older Utgard GPUs (Mali 400, Mali 450). However, during the Opensource GPU Drivers BoF at Linaro Connect Bangkok 2019, Rob Herring, Technical Architect at Linaro and Tomeu Vizoso, Principal Software Engineer at Collabora, discuss the status of drivers, and I learned about an open source driver for Mali Midgard (Mali-T6xx, Mali-T7xx) GPU called Panfrost. As we’ll see below, the driver is already capable of running basic demos, has been upstreamed to Mesa, and tested […]
