Настал третий за 12 лет случай, когда в профессии программист-микроконтроллеров понадобилось вспомнить школьную математику. В этом тексте я представил перевод AppNote(а) "The mathematics of two-way ranging". Также добавил свои комментарии в те места, которые неочевидны при первом прочтении.Тема нужна для определения расстояния между двумя радио трансиверами, которые могут определять моменты времени прихода и отправки радиоволны. Такое умеют делать UWB трансиверы, например чип DW1000. Read more Read more ›

Journey to find a headset with a good side talk cancellation mic for calls in an open office

Add to bookmarks Don't show Habr

Murz @ Habr 3 place · 03/17/2023 02:04 EDT

TL;DR: All AI-based noise cancellations suck, only the physical cancellation technique works! And physical cancellation is implemented well only in Jabra devices yet, but other features suck them! All Bluetooth headsets suck too! So, no solution yet, just complaints!The environment: I work in a pretty talky office room, where sit around 10 people, and all of them have many online conferences every day, including me. So, silence in the room... Read more ›

In most manuals, the exercises are similar to each other and not particularly interesting: create another address book, draw a circle using turtle, develop a website for a store selling some kind of "necessary" advertising nonsense. Too far from the authentic imitation of "The Matrix". Although…How about taking over the control and starting to invent exercises yourself?Would you like... Read more ›
