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.

Design of a NAND gate using the ICPS PDK
Table of Contents Table of Contents Introduction Tools Setup PDK Installation Linux Windows and Mac OS Drawing the Schematic Create the Netlist Simulation Drawing the Layout Performing Checks DRC - Design Rule Check DRC Troubleshooting LVS - Layout Versus Schematic LVS Troubleshooting Final Words Introduction
In this blog post I would like to show you how to create your own NAND gate using the newly released ICPS PDK. I highly recommend following the tutorial for yourself to get some hands-on experience. For comparison, you can find all the resulting source files in this repository.
If you have no idea what a Minimal Fab or the ICPS PDK or SOI-CMOS is, fear not! Please read my previous blog post which...
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...
Fritzing 1.0.2 released
Fritzing 1.0.2 is a feature release. It has been tested on Windows 10, Windows 11, macOS Ventura, macOS Monterey, Ubuntu 20.04, and Ubuntu 22.04. It is designed to work on all Linux variants with glibc >= 2.31 (64 bit Intel/AMD). Changes since 1.0.1. Copper fill The Copper Fill algorithm is now vector based. This fixes a number of bugs along, especially with Ground Fills, most prominent the annoying horizontal gaps in the copper fill. It results in higher precision, and more predictable behavior. It also enables a number of Gerber improvements and new features for PCBs in the future. The...
Happy New Year 2024 from Dangerous Prototypes
Happy New Year!
Thank you for reading the blog and being part of our community in 2023! We’re looking forward to more open hardware projects, more how-tos, more videos, more free PCBs, and more hacking in 2024.
Merry Christmas!
Merry Christmas and Happy Holidays to all. May you find many PCBs and other electronics wizardry under your tree or pole.
Remember, support is available on Christmas. Just give us a shout in the forum.
About Minimal Fab and the ICPS PDK
Introduction
Recently I participated in the Minimal Fab Design Contest. I had a go at designing a transmission-gate D-FF using the provided template for the layout. You could only use the first metal layer to connect devices.
It was actually selected for fabrication! This image shows the layout of the wafer with all the submitted designs:
My design is the second die in the first row of the 5x5 array.
This was only possible because the Industrial CPS Research Center (ICPS) at AIST (Advanced Industrial Science and Technology) in Japan open sourced their PDK for the Minimal Fab SOI-CMOS process. In a follow-up blog...
Ламповый дисплей для компьютера. Часть 2 – ускорение и фокусировка электронов в ЭЛТ
В предыдущей части я привел обзор ряда подходов к созданию необычного дисплейного устройства. В отличие от приведенных примеров мне хотелось создать дисплей, который будет пригоден для регулярного пользования. Для этого я выбрал круглую индикаторную ЭЛТ от радиолокационной установки с зелёным цветом свечения экрана. О том, как удалось заставить её работать, рассказывается в этой статье.
