Долго. Дорого… Делать гаджет в России – учиться, терять деньги, жить на работе

Привет! Я Игорь, создатель проекта гражданского мониторинга Nebo и это моя первая статья на Хабре, в которой хочу поделиться опытом разработки гаджета.

Важное: наша команда состоит из дизайнера, программиста и инженера. Множество работ мы закрывали своим трудом, учились, реальные расходы могут вырасти X10. Мы сильно экономили, возможно это станет полезно кому-то.

Изначально мы создали проект, чтобы с помощью недорогих девайсов определять загрязнение воздуха в Красноярске. В нашем городе люди часто жаловались на удушливый смог, и очень часто официальные данные оставались не актуальными. Этому смогу местные жители даже дали специальное определение «чёрное небо».

Free Stuff - April 2022

The April recipient for the Great Scott Gadgets Free Stuff Program is Anmol, a high school student in India! Anmol learned about Great Scott Gadgets after watching Michael Ossmann’s video on complex numbers, which is part of his Software Defined Radio with HackRF training video series. Anmol is the IT president of their school and is excited to use the HackRF we will be sending them to share the world of Software Defined Radio with other students.

Free Stuff - March 2022

The March recipient for the Great Scott Gadgets Free Stuff Program is Katerina Autumnrain! Katerina had such an enthusiastic and detailed application to the Free Stuff Program that we just had to send her the HackRF One she requested. In her application she had this to say:

“I believe that the HackRF could enable me to open up the oft more confusing aspects of radio, particularly modulation modes like QAM and digital systems like satellites and P25/DMR. I’d also like to try and promote the higher frequencies (33cm and beyond). Once the bandwidth and frequency limitation is lifted I can more...

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 –...
