OsmoDevCall: "SS7 and SIGTRAN in 2G/3G networks"
I've presented a talk SS7 and SIGTRAN in 2G/3G networks as part of the OsmoDevCall talk series on Osmocom and related technology.

FemtoStar: taking aim for the stars
Networking and communication is something that has been on our minds as of late. As many of you are surely aware, we have started developing our own solution to private and secure peer-to-peer and group text messaging based on the PineDio gateway system, available next month.
Chip Crisis Status
Oct 21, 2022
Current status: Production is stable and on-going! We don’t foresee any shortages of Omega2 devices or changes to lead time through Q2 2023 Our core focus since the beginning of the chip crisis has been strengthening our supply chain to make sure we can still produce and ship Omega2 devices – we’re happy to report this focus has paid off Our distributors Mouser and Digikey are being continuously resupplied! See our Buy page for direct links for each product Accepting orders directly from customers Lead time is 12 weeks and other terms will apply See our volume ordering page for more details and to get...The Chip Crisis and Onion
There’s been considerable turbulence in the electronics world the past six months. What’s now being called the chip crisis has affected companies big and small across a wide range of industries.
Onion is one of the companies impacted by all of this, and in this blog post, we will share the details of what’s happened, how we’ve adjusted, and what you can expect from here on out.
What happened?Price increases and longer lead times across the electronics component markets started in late 2020. The explanation was supply chain disruptions due to COVID-19 had finally started impacting electronics component manufacturers.

Домашняя микроскопия ч. 2 (Смотрим разное!)
Как показала практика, реальный микромир в окуляре – совершенно не похож на картинки, которые мы видели в школьных учебниках, или картинки художников в медийном пространстве.
Эта статейка будет проще чем предыдущая, но интересней прохожему пользователю – мы посмотрим кучу разных штуковин и просто познакомимся с микромиром. Подсовываем под объектив всё подряд, и комментируем. :)
Помните, что все фото – кликабельны.
Т.к. элементы на них малы(не только физически, но и на мониторе), то рекомендую растягивать их на весь экран(круглая кнопка в верхнем правом углу), либо открывать в новой вкладке.

Управляем контактами GPIO из C# .NET 5 в Linux на одноплатном компьютере Banana Pi M64 (ARM64) и Cubietruck (ARM32)
Когда заходит речь про программирование на C# .NET для одноплатных компьютеров, то разговоры крутятся только в основном вокруг Raspberry Pi на Windows IoT. А как же Banana/Orange/Rock/Nano Pi, Odroid, Pine64 и другие китайские одноплатные компьютеры работающие на Linux? Так давайте это исправим, установим .NET 5 на Banana Pi BPI-M64 (ARM64) и Cubietruck (ARM32), и будем управлять контактами GPIO из C# в Linux. В первой части серии постов, подключим светодиод и кнопку для отработки прерываний и рассмотрим библиотеку Libgpiod (спойлер, библиотеку так же можно использовать в C++, Python) для доступа к контактам GPIO.
Let's make MiRAKles happen
Many of you are already aware that we are very interested in LoRa®. We hope to use the technology for both traditional IoT applications as well as in less orthodox ways, such as peer-to-peer text communication and even group text-messaging.

Kyle Kaminky from Arvada, Colorado emailed us in October to ask for a HackRF One. He’s an EE with a young family who told us, “After becoming familiar with my HackRF One and GNU Radio, I hope to use it to begin making tutorials on wireless communications and other RF topics. I picture a series of follow-on classes to Michael Ossmann’s DSP course. I would also enjoy getting enough experience and expertise to be able to write my own GNU Radio blocks and post them online for others to use to aid in their SDR projects. Ultimately I want...
