Second LUNA Enclosure Update

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

We have an update on the enclosures! We have received 10 enclosures from our manufacturer and we are impressed.

A LUNA in a case measures 2 inches by 2.5 inches and weighs 103 g with the hardware and lightpipes installed. I’ve been carrying mine around constantly like a pet rock since it has such a comfortable weight. The case has held up really well, regardless of the wine, pesto, sesame oil, and other sauces I’ve gotten on it while cooking. The USB-C ports have a satisfying amount of...

Replacing wifi coax, modifying bios to allow new wifi cards, unsticking tired clock chips, DIY custom power suppy plugs, de-flickering backlight and more. Somehow my best laptop yet.

The History of LUNA

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

Ten years ago this summer I quit my day job at a radio research lab and made Great Scott Gadgets (GSG) my full-time job. I dedicated myself and the company to our mission: to put open source tools into the hands of innovative people. One of the first things I did at that time was to make a list of products I was interested in making. That list included “USB swiss army knife”. I didn’t know how to make such a thing at the time,...

Open Source Clair de Lune

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

Open source is at the heart of everything Great Scott Gadgets does. When we design hardware, we publish the KiCad design files, firmware, and software under open source licenses. We try to ensure the documentation, tutorials, research papers, and videos we publish are openly licensed as well. It is the GSG way. While preparing for this Crowd Supply campaign, we took our commitment to open source even further by ensuring the music used in our campaign video is openly available too.

As we started thinking about our campaign video,...

Метеостанция на Banana Pi M64 (Linux, C#, Docker, RabbitMQ, AvaloniaUI)

Статей о создании метеостанции на базе Arduino не счесть. Можно сказать, если статья про метеостанцию, то это про микроконтроллеры Arduino, ESP32 или STM32. Но только не в этот раз. Будем запускать метеостанцию на Banana Pi BPI-M64 под Linux, без использования Arduino-подобных оберток в виде WiringPi, на C# .NET5. Пример метеостанции является демонстрацией встраиваемого решения работы с GPIO, датчиками и вывода пользовательского интерфейса напрямую на LCD. В решении используется: Linux (Armbian) — основная ОС, .NET и C# — платформа для создания прикладного ПО, AvaloniaUI — графической интерфейс с интерактивными графиками и анимацией, Docker — инструмент для развертывания, управления, доставки приложений, RabbitMQ...
