Мой маленький триод: Ламповая ЭВМ — это магия

Экспериментальная 3U декатронная ячейка. Модуль декатрона А103 со схемой шифратора и переноса
Пришло время возобновить славную традицию ежегодного первоапрельского дайджеста по моим безумным вычислительным проектам. В прошлой трилогии [1], [2], [3] я рассказывал про создание де-факто самого быстрого в мире релейного компьютера BrainfuckPC. После трёх лет раздумий я наконец-то готов начать активную фазу строительства уникальной ламповой ЭВМ с кодовым названием DekatronPC. Читать дальше →

Introducing the PineBuds and PinePod. Seriously.

People are frequently asking us to create more mainstream devices such as an inkjet printer or a microwave, and for a good reason. Complex open devices such as the PinePhone are both exciting and fun, but they also aren’t for everyone.

Efabless’ CLEAR, a Fully-Open RISC-V ASIC Built on chipIgnite, Nears its Goal with Days to Go

https://invidious.privacyredirect.com/watch?v=S0pV1gltm-Q

CLEAR, a fully-open development board built around a RISC-V embedded-FPGA application-specific integrated circuit (ASIC) designed by Efabless as a showcase of what its chipIgnite platform can offer, is entering the last days of its crowdfunding campaign with just a handful of boards left to reach its goal.

“CLEAR is an open source FPGA ASIC delivered to you on its development board and its open source software development tools and all the ASIC design tools used to create it,” Efabless explained of the project at its launch earlier this year. “That’s for you to create your own – yes that’s right –...

March Update: Introducing the QuartzPro64

This month we’re announcing the QuartzPro64 - a new single-board computer based on Rockchip’s powerful RK3588 SoC. This is our first Pro-grade SBC since the introduction of the ROCKPRo64, and I believe it to be a worthy successor to the much revered Pro lineup.

Free Stuff - February 2022

The February recipient for the Great Scott Gadgets Free Stuff Program is Matthew Hilts! Matthew is a student at the University of Dayton who will be spending his Spring semester learning about and using GNU Radio. To help enhance his studies we have sent Matthew a HackRF One. We look forward to hearing about what he learns!

Ten Reasons to use SiliconCompiler – Including SPDX Provenance Support

Zero ASIC’s chief executive Andreas Olofsson has called for “all chip designers” to try out the open-source SiliconCompiler build system, showcasing his top ten reasons for giving it a go – including a provenance feature which supports the Software Package Data Exchange (SPDX) standard.

“We have been working hard on our open source SiliconCompiler build system for a year now and it’s coming together really nicely,” says Olofsson. “I have been doing chip design and CAD development since 1998 (Perl, TCL, make…) and this is light years ahead of anything in the industry. You owe it to yourself to at least...
