Вебинар посвященный вопросам применения SiC MOSFET 650В

14 апреля пройдет вебинар, посвященный вопросам применения SiC MOSFET 650В в источниках питания. Может быть полезно для расширения кругозора по современной элементной базе. Материалы на английском языке, но если нужно — вопросы на русском можно задавать сюда

Пример DC/DC выше демонстрирует как можно использовать улучшенные параметры SiC транзисторов нового поколения для повышения КПД и снижения массово-габаритных показателей преобразователей. Примечательно что предыдущий вариант также сделан на SiC и сам по себе существенно меньше альтернативного решения на обычных кремниевых MOSFET.
В случае интереса к теме, по мотивам вебинара можно сделать развернутую публикацию с ответами на часто задаваемые вопросы по теме...

PinePhone UBports Community Edition Pre-Orders Now Open

PinePhone UBports Community Edition mock-up; final product may differ in appearance.

I am proud to announce that the PinePhone UBports Community Edition is now available for pre-order with an estimated shipping date of late-May, 2020. Community editions are meant to bring exposure to partner-projects operating systems and communities, as well as help finance ongoing development. 

Самодельный лазер на парах марганца

В этой, юбилейной 10ой статье я опишу, что же является логическим следствием, продолжением моего самостоятельного лазеростроения. После построения источника питания, который подходит для накачки импульсных лазеров на парах металлов и приобретения опыта работы с готовыми активными элементами лазеров на парах меди и её соединений оставалось только изготовить активный элемент лазера (далее — АЭ) полностью самостоятельно, при этом с новой рабочей средой.

I2C Scanner

Since always when I am working with I2C devices I need the scanner I will post here for me and for others:
#include <Wire.h>
void setup()
{
  Wire.begin();
  Serial.begin(115200);
  Serial.println(F("\nI2C Scanner"));
  byte error, address;
  int nDevices;
  Serial.println(F("Scanning..."));
  nDevices = 0;
  for(address = 1; address < 127; address++ )
  {
    Wire.beginTransmission(address);
    error = Wire.endTransmission();
    if (error == 0)
    {
      Serial.print(F("I2C device found at address 0x"));
      if (address<16)
        Serial.print("0");
      Serial.print(address,HEX);
      Serial.println(F("  !"));
      nDevices++;
    }
    else if (error==4)
    {
      Serial.print(F("Unknow error at address 0x"));

March Update: Manjaro on Pinebook Pro & PinePhone Software

COVID-19 recovery in China is underway and factory work is slowly returning back to normal. This is good news, and we hope to have a constant stream of updates for you in the coming weeks. That said, we’re taking it one step at a time, since factories are still at 20% of the normal manufacturing capacity and it’s hard to predict the recovery pace. So rather than offering you my guesstimates for particular device availability, we will make announcements once all stages of production are secured for each device. Frankly speaking, this also means that announcements will likely drop suddenly;...

Самодельный лидар: OpenTOFLidar

В этой статье я хочу рассказать про свой проект импульсного (TOF) Open Source лидара — о том как я его делал, и каких результатов удалось добиться.

February Update: Post CNY and FOSDEM Status Report

Nemo Mobile and Ubuntu Touch on the PinePhone at FOSDEM 2020

A lot has happened in the past month. PinePhones have finally begun arriving in the hands of their owners, we had a great showing at FOSDEM, and new hardware was announced. If you haven’t yet read my post about our trip to FOSDEM and the new devices, then I encourage you to do so. Behind the scenes, much work is currently being poured into consolidating and evolving current projects as well as exploring new ones. There are some really exciting months ahead of us! 

Michael "mickeyl" Lauer: Welcome, 2020

Here's the new decade. 2019 went by as an important year where I regained some of my health, discipline, and motivation. Next to the inevitable iOS development, the most important milestones were the release of the 2nd edition of my Vala book and my first music album after more than two decades of inactiveness. I'm looking forward to this decade. The best is yet to come.

FOSDEM 2020 and Hardware Announcements

PINE64 get-together with community devs and partner-projects at FOSDEM 2020

Sorry for the delay in delivering FOSDEM news and announcements to you - I was too occupied with great company, splendid beer and shouting at hundreds of people across our stall table. It was awesome to see so many familiar faces, meet new ones and socialise with projects we usually don’t get an opportunity to talk with. 

Setting the Record Straight: PinePhone Misconceptions

I take no pleasure in writing this blog post. In fact, even as I am writing these words I am internally torn on whether this is the right approach to addressing the problem on hand. Whether I’ve chosen the right approach remains to be seen, but regardless, I now feel it’s time to confront misconceptions about the PinePhone.
