A Closer Look at the SiFive RISC-V Rack Cluster

https://player.vimeo.com/video/652473940

SiFive collaborated with AB Open to create a rack-mount RISC-V cluster based around the SiFive HiFive Unmatched developer platform for compute and a SiFive HiFive1 Rev. B development board for control. In this article we take a closer look at the design of the cluster and consider some of the key use cases.

The objective was quite simply to package together a total of four SiFive HiFive Unmatched boards in a rack-mount enclosure, that would serve as a powerful and convenient way to host and use a native RISC-V development platform. From this it was decided that the solution must feature:

Shutting Down GSG Project-Specific Mailing Lists

Thank you to everyone who has been a part of the GSG project mailing lists. We at Great Scott Gadgets appreciate all of the conversations and friendships that have been forged on these lists. Over the last few years we have not given our project-specific mailing lists the attention they deserve; instead we have been focusing our efforts on Discord and GitHub. As such, we will be disabling all the mailing lists except for GSG-announce. Links to the mailing list archives for Ubertooth, YARD Stick One, GreatFET One, and HackRF will all remain available on their individual product pages. Current...

Future Corporation Partners with AB Open for Unique RISC-V PC Project

https://player.vimeo.com/video/644341183

FOR IMMEDIATE RELEASE

Custom-built RISC-V personal computer features open-hardware front panel.

Halifax, UK, 30th November 2021—Open hardware consultancy AB Open has built a unique personal computer based on the free and open source RISC-V instruction set architecture, following a partnership with Future Corporation.

Following AB Open’s earlier success in being one of the first in the world to assemble a complete RISC-V PC, Future Corporation partnered with the company to build a more powerful version based around SiFive’s HiFive Unmatched board.

To this, AB Open has added a GNU/Linux-based operating system, dedicated graphics processing card, high-speed solid-state storage, and Wi-Fi connectivity, housed in a...

Программируем микроконтроллеры ESP32 и STM32 на C# (nanoFramework)

.NET nanoFramework — это бесплатная платформа с открытым исходным кодом, основанная на .NET и предназначена для малых встраиваемых устройств, микроконтроллеров. С её помощью можно разрабатывать различные устройства для Интернета вещей, носимые устройства, научные приборы, робототехнические устройства, можно создавать прототипы и даже использовать на промышленном оборудовании. В первой части мы познакомились с платформой .NET nanoFramework, её архитектурой, основными возможностями, посмотрели примеры программного кода. Теперь перейдем к практике, установим nanoFramework на микроконтроллеры серии ESP32 и STM32, напишем первый «Hello World!», поработаем с аппаратными интерфейсами, и оценим переносимость кода с «большого» .NET на платформу nanoFramework.

LUNA Delayed

Note: This is a crosspost of a Cynthion update on Crowd Supply: https://www.crowdsupply.com/great-scott-gadgets/luna/updates/luna-delayed

LUNA is delayed. All of us at Great Scott Gadgets are sad to have to give this news, but the global chip shortage and supply chain chaos has impacted our LUNA manufacturing and delivery timeline more deeply than anticipated. Unfortunately, LUNA is now expected to start shipping December 2022 because the lead time for the ECP5 FPGA chip we use on LUNA doubled between July and September. There isn’t a suitable substitute component for the ECP5, so our timeline depends on Lattice’s production schedule for this chip. Please...

All Invited to the OpenTapeOut Open Source ASIC Design Conference This Weekend

The free and open source silicon community, both established and simply interested, is invited to a new event this weekend: the OpenTapeOut Conference 2021, hosted by Zero to ASIC course creator Matt Venn.

“We encourage all of you folks to join us at what we hope will be the start of a revolution! No matter who you are or where you are from, don’t care what you did, as long as you love ASICs [Application Specific Integrated Circuits] and electronics in general,” the event’s organisers explain. “We don’t expect you to have any serious pre-knowledge in ASIC design. Actually we’d love...

October Update Follow-up

Happy Halloween! As promised earlier this month, here is the follow-up to the October community update. Some of the topics I’ll touch upon will be covered in more detail in November. I’ll keep this one brief.
