[Перевод] Новый высокопроизводительный одноплатный компьютер BeagleV построенный на открытой архитектуре RISC-V за $119+
До недавнего времени платы построенные на процессоре RISC-V такие как Kendryte K210, невозможно было использовать для высоко ресурсоемких задач, т.к. производительность конечных была очень низкой. В частности одноплатный компьютер XuanTie C906 на базе Allwinner RISC-V можно было использовать только для нишевых небольших задач, например в качестве камеры из-за отсутствия аппаратного графического ускорителя и наличия только 256 МБ оперативной памяти. Можно использовать одноплатные компьютеры такие как SiFive HiFive Unmatched или PolarBerry, но стоимость конечной системы составит сотни, а то и более тысячи долларов, что является весьма дороговато.

January Update: Happy New Gear!
Happy New Year everyone! Let us all hope that the difficulties brought about by the COVID-19 virus are now waning and that more aspects of our lives will return to normal soon.
Diodes part 4: Glowing ionic diodes recreated & my ionic thesis research
Ionic diodes, failures in researching potential transistor-like devices and misdirection in transistor proofs. Lots of pretty pictures.
I owe you a riddle
The riddle has been solved and we’ll be contacting the winner in the coming days. The comments section has now been locked until January. Thank you to everyone who played along!
December Update: The Longest One Yet
Welcome to the last community update of the year. I want to start this month’s update by thanking everyone who helped us make this challenging year a fruitful and successful one.
Free Stuff, April 2020–June 2020
April 2020
Dave Ferguson of the Woodinville (WA) Emergency Communications Team asked us for a HackRF One in April. This volunteer ARES group is turning a donated fire department aid truck into a mobile communications center that will service local public events (runs, bike rides, etc.) as well as provide essential communications via ham radio during emergencies. Their new HackRF One will allow them to watch communications across the entire spectrum and to potentially automate their systems.
May 2020We sent a couple of YARD Stick Ones to the MCH2021 Badge Team. We can’t say any more than that, other than they are...
Pine Store Community Pricing & Online Retail Stores
In 2021 you’ll see online retail Pine stores open in Europe, North America and possibly also worldwide at a later stage. Let me start by making one thing clear - the current Pine Store isn’t going away and the pricing in the Pine Store will remain unchanged.
KDE Community Edition is now available
We are pleased to announce that the KDE Community Edition (CE) PinePhone is now available for pre-order. This edition of the PinePhone ships with a tailored build of Plasma Mobile built upon Manjaro Linux, and it is the culmination of ongoing efforts to bring the popular Plasma desktop environment to the smartphone.
November Update: KDE PinePhone CE And A Peek Into The Future
Welcome to this month’s community update! We’ve got exciting news to share, but before I proceed in doing so I’d like to thank Gamiee, JF, and PizzaLovingNerd for contributing to this blog entry and Clover for the final edits and proof-reading.
Wemos D1 mini reconnecting all the time to Arduino IDE
Lately I've acquired some Wemos D1 mini from Amazon and I've noticed an annoying behavior.
Every 2,3 seconds a disconnect and a reconnect sound was produced making impossible any software development on them along with any debugging.
The problem was a the 3V3 on the CH340C (USB to serial).
After I've added a 100uF capacitor on the 3V3 and not everything is fine again.
