Teardown for the Ring doorbell camera. It’s not good.

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.

Finally debugging an old project. It’s a mess but we can work with this.

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.

We now ship also from the USA

Since I started manufacturing and selling nixie tubes and clocks, our customers from the USA formed the single biggest market for us. I remember years where we shipped 50% of our clocks to the USA. Today, I am excited to announce an improvement for our US customers – cooperation with Nicholas Stock from California. Nick will ship our clocks to US customers and also do some warranty and repair services. This change means faster delivery, no import process, lower risk of damaging the package and lower overall cost of the delivery.

So, who is Nick? If you are a member...

Hellobox B1 satellite finder teardown

It is a very simple device for about $15. The main SoC is GX6605S. There is some limited info about this chip on C-SKY page and some technical docs at their tools repo. It communicates with a Bluetooth module TLSR8266 using UART. There is also 4MB SPI flash holding the whole bootloader called GxLoader, Linux kernel and filesystem with the main app. The last important chip is RDA5815M which handles the RF to I/Q conversion. In the future I plan to add an USB-to-Ethernet adapter and repurpose it as an cheap opensource SAT>IP server.
