Ламповый дисплей для компьютера, часть 5: коллектор, видеоусилитель и изображение

Рад приветствовать всех, читающих уже пятую часть цикла статей о ламповом дисплее для компьютера, в которой можно рассмотреть долгожданный результат проделанной опытно-конструкторской работы. Прежде чем перейти к такому описанию, кратко напомню содержание предыдущих частей:
Часть 1 – обзор существующих концепций для построения необычных дисплейных устройств и выбор своей собственной Часть 2 – запуск ЭЛТ и фокусировка электронного пучка в ней Часть 3 – описание блоков синхронизации и кадровой развертки Часть 4 – описание финальной сборки блока питания и блока разверток, получение растра на экране

Cynthion Design Work Completed

Note: This is a crosspost of a Cynthion update on Crowd Supply: https://www.crowdsupply.com/great-scott-gadgets/cynthion/updates/cynthion-design-work-completed

We are happy to say that early this month we completed the design work for Cynthion! This milestone is the culmination of yet another three months’ worth of work. Since our October update we have:

revisited the EMC testing lab for another round of pre-compliance testing,

used the EMC testing results to improve signal integrity on Cynthion and produce another hardware revision,

ordered another revision of the Cynthion enclosure prototypes,

designed and ordered prototypes of the Cynthion packaging,

produced another Cynthion hardware revision to fix minor issues,

rearranged the Cynthion schematic,

updated documentation in Cynthion-related...

Minimal Fab Special Award

In November of last year, I participated in the Minimal Fab Design Contest for SemiCon Japan 2023. You can find more about my submission and Minimal Fab in this previous blog post.

At the time I wasn't expecting too much, it was already fun to submit my design.

Shortly after, I was informed that I would receive the Minimal Fab Special Award for my design! The organization comittee was even so kind as to send me the certificate and a wafer.

It's a wafer with the Minimal Fab mascot made of Au/Ti/Si substrate. What amazes me the most is just how tiny it is 🤩️

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.

Outage January 21st

We regret to inform you that we are currently experiencing an outage in our main cluster. We are currently actively investigating the cause of this issue. We understand the inconvenience this may cause and appreciate your patience during this time.

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...
