ANAVI Dev Mic is a digital omnidirectional microphone based on Raspberry Pi RP2040 MCU (Crowdfunding)

The ANAVI Dev Mic is an open-source microphone board from ANAVI Technology in Plovdiv, Bulgaria powered by the Seeed Studio XIAO RP2040 module and an omnidirectional digital microphone from STMicroelectronics. It is a compact and affordable product that outperforms USB microphones in artificial intelligence and machine learning voice applications. The design is simple and unassuming, with the Seeed Studio XIAO RP2040 module in the center, surrounded by a USB-C port for power and programming and 9 GPIO pins for extensibility. The STMicroelectronics MP23DB01HP microphone (MK1) is mounted on the top of the board with a small hole on the bottom. It is a compact, low-power, digital MEMS microphone capable of capturing sounds from different directions with very low distortion. It uses a PDM (Pulse-Density Modulation) interface created via the programmable inputs/outputs (PIO) on the RP2040. The ANAVI Dev Mic is applicable for conducting AI/ML research, building a voice recognition platform, […]

Linamp – A Raspberry Pi 4-based audio box with Winamp look and feel

Linamp is a media player box based on Raspberry Pi 4 SBC and a touchscreen display with a GUI that replicates the popular Winamp media player’s GUI that older readers may remember from the late 90s and early 2000s when it was one of the most popular music players for Windows. Rodmg found some renders of what a real Winamp player could look like online, and it inspired him to create his own. As its name implies Linamp runs on Linux (DietPi) instead of Windows, and the hardware is based on a Raspberry Pi 4, a 7.9-inch touchscreen display, a USB DAC, and various connectors and cables, all housed in a custom-designed metal enclosure and a 3D-printed front cover both designed with Onshape. Here’s the complete list of off-the-shelf items used for the build: SBC – Raspberry Pi 4 with a 32 GB microSD card, a set of passive heat […]

picoLLM is a cross-platform, on-device LLM inference engine

Large Language Models (LLMs) can run locally on mini PCs or single board computers like the Raspberry Pi 5 but with limited performance due to high memory usage and bandwidth requirements. That’s why Picovoice has developed the picoLLM Inference Engine cross-platform SDK optimized for running compressed large language models on systems running Linux (x86_64), macOS (arm64, x86_64), and Windows (x86_64), Raspberry Pi OS on Pi 5 and 4, Android and iOS mobile operating systems, as well as web browsers such as Chrome, Safari, Edge, and Firefox. Alireza Kenarsari, Picovoice CEO, told CNX Software that “picoLLM is a joint effort of Picovoice deep learning researchers who developed the X-bit quantization algorithm and engineers who built the cross-platform LLM inference engine to bring any LLM to any device and control back to enterprises”. The company says picoLLM delivers better accuracy than GPTQ when using Llama-3.8B MMLU (Massive Multitask Language Understanding) as a […]
