March Update: Status Report

Welcome to this month’s community update. We’re now facing one of the most challenging electronics manufacturing circumstances in years, and possibly even in all of electronics history. Despite this, I’ve got some good news to relay this month, including a Quartz64 pilot production-run, SOEdge being available next month and plenty of community news.

MQTT BROKER on ESP8266 or ESP32

 Since lately I received some messages about the old MQQT broker on ESP8266 I was thinking that it might be a good idea to restart the project.

The plan will be to moved it back to ESP32, where was originally started, in fact was started on ESP31B.

I will do that if there is some interest in this project, also if we can share the work.

Please let me know in the comments if this project makes sense or not.

LiquidCrystalRus - небольшое обновление

Недавно в проект LiquidCrystalRus на GitHub пришло issue по поводу того, что функция print при попытке выводить некоторые неалфавитно-цифровые символы из знакогенератора дисплеев на основе HD44780U, несправедливо их калечит. И я решил скорректировать алгоритм трансляции - чтобы он применялся строго к символам русского алфавита. Чуть больше кода из-за проверок, но зато можно так:
lcd.print("Дисковод 5\xf0");
На экране мы увидим:  Дисковод 5¼
Плюс добавил пример DumpCharacters, выводящий построчно весь знакогенератор дисплея, что снимает вопросы по поводу того, есть ли там кириллица в принципе. 
Надеюсь, кому-то пригодится )

Free Stuff, July 2020–September 2020

July 2020

Anna from South Carolina had a lame quarantined birthday in July, so we sent her a present- a GreatFET One. She recently started taking cybersecurity classes and wants to learn about hardware hacking.

Ed from the Suffolk County (NY) Radio Club wrote to us in August to ask for free stuff for learning activities with their new members, mainly scouts and their parents. We sent a bunch of Throwing Star LAN Tap Kits, and hopefully they’ll be able to get together to use them soon.

Axell Macclawd is a security researcher in Brazil. He requested a HackRF One for...

Omega2 Lead Time Temporarily Increased

Updated: May 7, 2021

We want to make everyone aware the lead time for Omega2 volume orders has been temporarily increased to 16 weeks. The extended lead time is currently in effect and applies to all Omega2 devices when purchased directly from Onion:

This temporary extension to the lead time is a result of the global microchip crisis.

We are working with our suppliers and manufacturing partners to minimize the impact this has on our customers.

Visit our distributors Mouser and Digikey – they will continue to sell Omega2 devices in small and large quantities...
