Изготавливаем самодельный электролюминесцентный индикатор
В прошлый раз я показывал вам свою коллекцию советских электролюминесцентных индикаторов. Я капитально подсел на эту тему и последние три месяца пытаюсь изготовить самодельный индикатор удовлетворительного качества.
Дерпи Хувс ловит маффины. Стекло. Эпоксидка. Зелёный люминофор.
Я потратил целых три месяца и изготовил добрую сотню образцов, прежде чем у меня стало получаться что-то сносное. На данный момент я провёл пять экспериментов и изготовил две серии прототипов.
Думаю ещё через несколько месяцев я смогу написать уже Исчерпывающее руководство по изготовлению самодельных индикаторов, с подробным обоснованием всех возможных комбинаций материалов, но пока же ограничусь описанием проведённых экспериментов и полученными текущими результатами^ Читать дальше →
Free Stuff, July 2021–September 2021
July
July’s recipient is Nick with Urban Rivers. This organization is building a floating park in the Chicago River that has been getting a lot of bird layovers. Nick wants to integrate a HackRF One into Motus Wildlife Tracking System to study migratory patterns and capture a more complete picture of avian travel.

Free Stuff, April 2021–June 2021
April 2021
Eric wrote to us on behalf of the Chaffey High School (Ontario, CA) Tech Club, asking for a HackRF One. He’ll be graduating from the University of Tulsa soon and as a past president of the club, he zooms into the club’s meetings to offer help with computer science and cybersecurity topics. Now he’ll be able to help the students use a HackRF One for their own projects. They’ll also be holding workshops on RC Car Hacking, Listening to and Broadcasting AM/FM Radio Signals, and Mapping Planes with ADS-B Signals.

Free Stuff, January 2021–March 2021
January 2021
The first Free Stuff recipient of 2021 is Christos Voutichtis, an artist in Gemany who asked for a HackRF One for his project, Order of Sound. He tells us, “This is an arrangement of five complex antenna receivers which make the electromagnetic waves that permanently surround us audible. This data, which we perceive as sound, is processed in a program (VVVV) that I have designed which enables the analysis to translate them into graphical elements, which are then rendered as an abstract architecture in the form of a real-time projection. The viewer enters an immersive megastructure of abstract data...
LUNA Now Uses Amaranth HDL
Note: This is a crosspost of a Cynthion update on Crowd Supply: https://www.crowdsupply.com/great-scott-gadgets/luna/updates/luna-now-uses-amaranth-hdl
Over the next while we will be updating the LUNA project to use “Amaranth HDL”, which is the new name whitequark and other maintainers have chosen for their project. Amaranth is the hardware description language used in LUNA. The Amaranth gateware provided with LUNA enables you to create USB devices in gateware, firmware or both. Amaranth also enables LUNA to customize itself to the task at hand, which gives it access to unique features like user-defined hardware triggering and simultaneous capture of additional external or internal signals. The...
December update: a year in review
Seasonal greetings from the PINE64 community team! In the last community update of 2021 we’ll take a look at progress made this year and discuss potential avenues to explore in 2022.
Testing a HackRF Clone
Like every open source hardware company, we’ve seen clones of our products for sale on the Internet. These clones arguably provide a valuable service to the community, making our designs more widely available and at a price more people can afford. However, they also have negative effects such as an increase on our technical support burden without a corresponding increase in revenue to pay our staff. When the quality of a clone is poor it may also degrade the reputation of our products.
Our most frequently cloned product is HackRF One. While we have every reason to believe that some of the HackRF clones...
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.
FeaturesThe 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:
