PicoMQTT – An MQTT Client/Broker library for ESP8266 and ESP32

PicoMQTT is a lightweight MQTT library for Arduino/PlatformIO optimized for ESP8266 and ESP32. It not only supports the MQTT Client mode like most existing solutions but also the MQTT Broker mode which transforms an ESP8266 or ESP32 board into an MQTT gateway replacing a Raspberry Pi board or an IoT gateway typically used for this task.

The library follows MQTT 3.1.1 specification, supports the publishing and consuming of arbitrary-sized messages, can deliver thousands of messages per second, and supports easy integration with the ArduinoJson library to publish and consume JSON messages.

AMD Alveo MA35D media accelerator transcodes up to 32 1080p60 AV1 streams in real-time

AMD ALVEO MA350 AV1 real-time encoding card

AMD Alveo MA35D media accelerator PCIe card is based on a 5nm ASIC capable of transcoding up to 32 Full HD (1080p60) AV1 streams in real-time and designed for low-latency, high-volume interactive streaming applications such as watch parties, live shopping, online auctions, and social streaming. AMD says the Alveo MA35D utilizes a purpose-built VPU to accelerate the entire video pipeline, and the ASIC can also handle up to 8x 4Kp60, or 4x 8Kp30 AV1 streams per card. H.264 and H.265 codecs are also supported, and the company claims its “next-generation AV1 transcoder engines” deliver up to a 52% reduction in bitrate at the same video quality against “an open source x264 veryfast SW model”. AMD Alveo MA350 highlights: Auxiliary CPU – 2x 64-bit quad-core RISC-V to perform control and board management tasks AI Processor – 22 TOPS per card for AI-enabled “smart streaming” for video quality optimization Memory – 16GB […]

PiEEG shield for Raspberry Pi enables brain computer interfaces (Crowdfunding)

PiEEG is an open-source hardware Raspberry Pi shield that measures electroencephalography (EEG), electromyography (EMG), and electrocardiography (ECG) bio-signals and provides a brain-computer interface to applications or robots for gaming, entertainment, sports, health, etc… Ildar Rakhmatulin, a Research Associate at Heriot-Watt University in Edinburgh, is passionate about open-source brain-computer interfaces and first created the IronBCI project based on ADS1299 and STM32 and published a research paper entitled “Low-cost brain computer interface for everyday use” about his work. But cost increases related to the semiconductors shortage of recent years meant the price for his “low-cost” project shot up to over $1,000. So he went back to the drawing board and created the PiEEG shield for Raspberry Pi now available on Crowd Supply. PiEEG shield specifications: ADC – Texas Instruments ADS1299 Analog-to-Digital Converter for biopotential measurements Supported SBCs – Raspberry Pi 3 or 4, and boards with the same 40-pin GPIO header. Host […]

Scrcpy 2.0 Android screen mirroring and control utility for PCs released with audio forwarding support

Scrcpy 2.0 Android screen mirroring and control utility for Windows, Linux, and macOS has just been released with support for audio forwarding that enables audio to be played back into the computer/laptop, instead of the smartphone, at least for mobile devices running Android 11 or greater. We first reported about Scrcpy open-source utility in 2018, and at the time, it worked relatively well in Ubuntu 16.04 but required quite a few steps for the installation, and it would lag from time to time. I could still use the mouse and keyboard to control my phone, send SMS, chat, browse the web, play games, switch between landscape and portrait modes, and so on. Five years later, Scrcpy 2.0 has been released, the installation is much easier, and new features have been implemented. Scrcpy 2.0 highlights: Quality – 1920×1080 or above Performance – 30~120fps, depending on the device Latency – 35~70ms Startup […]
