Санком. Неизвестный производитель оптических домофонов

Приветствую всех!
В начале лета этого года я уже рассказывал про домофоны с оптическим ключом. И так уж вышло, что в статье речь шла исключительно про самый популярный тип ключа с пятью тройками дырочек. Но, само собой, существовали и другие устройства.
Итак, сегодня поговорим об оптических считывателях и домофонах ранее неизвестной мне фирмы. Узнаем, как работали их ключи и разберёмся, как всё это запустить. Традиционно будет много интересного.

Cutting Pins for F Nixie tube | EP#3

https://invidious.privacyredirect.com/watch?v=9Gsk4Y-N4iA

Another version of a mold for manufacturing stems is in development. Meanwhile, I am trying the process of cutting wires to pins – this will be needed once the mold is ready..

Ламповый дисплей для компьютера. Часть 1 — обзор концепций и постановка задачи

Всем привет! Мне с большим трудом удалось побороть лень и начать писать новый цикл статей, но на этот раз не о лазерах. Дело в том, что лазеры – не единственный мой интерес, значительное место в списке интересов у меня занимает ламповая техника в её разнообразных проявлениях, и совершенно особый фетиш – советская ламповая радиолокационная аппаратура. Мне давно хотелось отвлечься от лазеров и создать что-то такое, что, как бы это ни звучало банально, не имеет аналогов. Потому вспомнил одну старую идею, очень долго лежавшую в «долгом ящике». И речь в статье пойдет о нестандартных устройствах отображения визуальной информации.

App note: The difference between current sense resistors and hall effect sensors for motor control

App note from Bourns’ comparing current shunt resistors and hall effect current sensing pros and cons. Link here (PDF)

Current sensing is an essential design function that is necessary in a broad range of applications. For example, current sensing is needed to detect a battery’s capacity, to measure current flow, or to calculate angles in motor control applications. Applications that can benefit from current sensing include Battery Management Systems (BMS), 3-Phase motor control units and On-Board Charging (OBC) Systems used in electric vehicles (EVs), and in other high energy charging-based designs.
Current sensing is also advantageous in medical equipment to detect leakage...

App note: A simple solution for LED overtemperature protection

Bourns’ new thermal cutoff device for LED protection can be found in this paper. Link here (PDF)

Compared to traditional lighting technologies such as incandescent and fluorescent lamps, LED lighting has a much longer life span, consumes far less energy and offers shock and vibration ruggedness. LEDs also produce very little heat and do not contain the toxic materials of predecessor lighting technologies.
One issue LEDs have is that they tend to fail when they overheat. The fabled long life of LEDs is very much dependent on them remaining cool or at least not being subjected to heat shock.
Bourns has recently released...
