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...

February Update: Show and Tell

Welcome to this month’s community update. As many of you know, we have now entered the Chinese New Year (CNY) period, which means that all manufacturing and related business activities have ground to a halt. It is always a mad rush to complete ongoing work prior to CNY, but now that the festive period is upon us we get a chance to catch our breath and evaluate the progress made.

The end of Community Editions

Today marks the end of the PinePhone Community Edition scheme. On behalf of myself, the Pine Store crew and the entire PINE64 community I’d like to thank the UBports Foundation, the postmarketOS project, Manjaro Linux, KDE e.V as well as the Mobian project for participating in bringing the PinePhone to tens of thousands of FOSS enthusiasts worldwide. We literally couldn’t have done it without you.
