Ламповый дисплей для компьютера, часть 4: блок питания, строчная развертка и первый растр
Краткое содержание предыдущих статей цикла:
Часть 1 – обзор возможных концепций и постановка задачи
Часть 2 – запуск ЭЛТ и фокусировка электронного пучка в ней
Часть 3 – построение канала синхронизации и блока кадровой развертки
В этой части будет рассказ о тех электронных узлах, которые я создавал дальше, а именно — описание окончательного оформления блока питания, переделки источника высокого напряжения кинескопа, строчной развертки и получения первого растра.

Bus Pirate 5 is here!
Bus Pirate 5 is the latest version of the multi-tool hackers trust since 2018. RP2040-based, color LCD, 1-5volt power supply and IO buffers, and more! Firmware, hardware and a fresh new forum are hosted at BusPirate.com, which I rescued from spammers a few years ago.
The software on this server (Dangerous Prototypes) is seriously outdated and there’s a load bearing laptop somewhere in the config, it was easiest to start over with all the latest tools. Soon this site will be ripped to a flat file/static site and archived.

The WS2812 has been around for a decade and remains highly popular, alongside its numerous clones. The protocol and fundamental features of the device have only undergone minimal changes during that time.
However, during the last few years a new technology dubbed “Gen2 ARGB” emerged for use in RGB-Illumination for PC, which is backed by the biggest motherboard manufacturers in Taiwan. This extension to the WS2812 protocol allows connecting multiple strings in parallel to the same controller in addition to diagnostic read out of the LED string.
Not too much is known about the protocol and the supporting LED. However, recently...

Revisiting Candle Flicker-LEDs: Now with integrated Timer
Years ago I spent some time analyzing Candle-Flicker LEDs that contain an integrated circuit to mimic the flickering nature of real candles. Artificial candles have evolved quite a bit since then, now including magnetically actuated “flames”, an even better candle-emulation. However, at the low end, there are still simple candles with candle-flicker LEDs to emulate tea-lights.
I was recently tipped off to an upgraded variant that includes a timer that turns off the candle after it was active for 6h and turns it on again 18h later. E.g. when you turn it on at 7 pm on one day, it would...
Ламповый дисплей для компьютера, часть 3: Синхронизация и кадровая развертка
В первой части я привел обзор возможных концепций для построения необычных дисплеев и описал свой замысел на основе круглой ЭЛТ от индикатора кругового обзора РЛС. Во второй части я начал описание пути реализации замысла, который начался с построения высоковольтного источника питания ЭЛТ и узла магнитной фокусировки электронного пучка. В этой же части я продолжу описывать электронные узлы, которые пришлось собирать в рамках этого проекта.

Free Stuff - October 2023
The October recipient for the Great Scott Gadgets Free Stuff Program is the Illinois Space Society, which is a student-run non-profit 501(c)3 aerospace organization at the University of Illinois Urbana-Champaign campus. The Illinois Space Society hosts a variety of technical projects and educational outreach programs. One of their largest technical projects, Spaceshot, is aiming to be one of the first collegiate teams to build and launch a two stage rocket to 100km, also known as the Kármán line, the beginning of space.
Over the past two years they’ve been working on creating flight computers that can accurately conduct state estimation at...
