Pine64 launch $50 smart speaker for Home Assistant tinkerers
20 days ago
- Pine64 launched PineVoice, a $50 smart speaker with RISC-V chip and open-source software.
- Hardware includes Bouffalo Lab BL606P SoC with Wi-Fi, Bluetooth 5.0, Zigbee, dual mics, speaker, and local wake word detection.
- Factory firmware uses Alibaba's YoC platform and Wyoming Satellite protocol for Linux-based Home Assistant, though Wyoming is deprecated.
- Specs: 32 MiB pSRAM, 16 MiB flash, 128 KiB ROM; intended as embedded device, not high-performance PC.
- Early-stage development; may have quirks; firmware updates expected; not a consumer-grade product.
- Pine64 focuses on low-cost, open hardware for developers; comparable price to Amazon Echo Dot and Google Nest Mini.
- Unlike cloud-dependent proprietary devices, PineVoice targets local, open-source networks.
- Available for $49.99 with USB cable, guide, 30-day warranty; suitable for tinkerers.
One man, two kernels, and a lot of RISC-V
25 days ago
- Yuri Zaporozhets develops multiple projects, including a RISC-V-based GateMate PC inspired by IBM PS/2, a System/359 mini-mainframe on FPGA, and ports/rewrites of QNX.
- He ported QNX 6.4 to RISC-V as QRV, later creating QSOE with two variants: one on the Skimmer microkernel and another on seL4, both under Apache 2.0 license.
- Zaporozhets uses AI tools like Claude LLM but has long-standing expertise, dating back to projects like RadiOS in 2003, focusing on open-source, low-level systems design.
Modder builds 8,192-core GPU at home out of RISC-V microcontrollers
14 days ago
- A modder built an 8,192-core GPU from RISC-V microcontrollers, each with an RGB LED, creating a combined graphics card and monitor.
- The project uses 8,192 chips (planned for 64,000 for 320x200 resolution), draws over 2,000 watts of power, and requires a custom 3D-printed tool for programming.
- Each microcontroller costs $0.13, leading to over $8,000 for the full array, with power supplied via a Corsair WS3000 PSU and custom converters.
- The design features custom six-layer PCBs in a circular arrangement, inspired by the Cray-1, and addresses challenges like cooling and high-current power delivery.
Book: RISC-V System-on-Chip Design
12 days ago
- RISC-V System-on-Chip Design is accessible to advanced undergraduates with limited background, covering concepts from operating systems, VLSI, and memory systems.
- It features easy-to-read explanations, sidebars, and humor, similar to Harris and Harris's textbooks, and includes open-source SystemVerilog code, validation code, and benchmarking tools.
- The book provides detailed design for microprocessor components, implementation of RISC-V microprocessors, and enables building processors on the open-source Skywater process.
- Authors James Stine and Sarah L. Harris are experts in computer arithmetic, VLSI, and digital circuit design, with backgrounds at institutions like Oklahoma State University and Harvey Mudd College.
- Published by Morgan Kaufmann in July 2026, it has 856 pages, ISBN-10: 0323994989, and ranks in categories like Integrated Circuits and Computer Hardware Design.
