АВК-6: Персональный Аналоговый Компьютер
Итак, перед нами персональный аналоговый компьютер АВК-6.
Аналоговые вычислительные машины в 60-70-е годы были способны в реальном времени решать системы дифференциальных уравнений до 60 порядка и выше, обеспечивая эквивалентное быстродействие в сотни миллионов операций в секунду, в то время пока цифровые ЭВМ только набирали обороты. Советская и зарубежная промышленность активно выпускала большие и малые аналоговые компьютеры и АВК-6 в этой истории — вершина развития настольных аналоговых компьютеров, удостоенная множества наград в СССР и за рубежом.
Я с детства мечтал заполучить АВК-6 и вот наконец могу провести на нем различные эксперименты, попытаться построить аттракторы, а главное — подтвердить миф о том может...
Несложные ходовые вакуумметры. Часть 1. Манометры сопротивления (Пирани)
На примере старинных барометрических манометров и разрядной трубки [1], коснувшись измерений остаточного давления в вакуумной системе, следом рассмотрим условно несложные вакуумметры ходовые ныне — тепловые и ионизационные — как выглядят, как работают, варианты (исторические, фабричные, самодельные), способы включения, особенности, интересные моменты. Условия задачи: любительская лаборатория-мастерская, общий курс — самодельные электронные и газоразрядные лампы.

Free Stuff - February 2026
The February 2026 recipient for the Great Scott Gadgets Free Stuff Program is David Wagner on behalf of the TU Wien Space Team, a collective of 100 students in Austria at the Vienna University of Technology. SpaceTeamSat1 (STS1) is the current CubeSat mission, which aims to develop a 1U CubeSat for educational purposes and operate it in orbit. In addition, a dedicated ground station is operated for communication with the CubeSat. Students in Austria will have the opportunity to run self-developed software on the satellite’s education payload. The payload of the CubeSat “STS1” consists of a Raspberry Pi to which...
Free Stuff - March 2026
The March 2026 recipient for the Great Scott Gadgets Free Stuff Program is Ramon Gallinad Corti, a final-year Telecommunications Engineering student from Spain. Ramon has a background in signal processing and SDR and has proposed a project he calls RF-Learn, an open source educational repository and YouTube video series in Spanish. RF-Learn will be structured in three progressive modules. The first will cover satellite signal reception: decoding NOAA weather satellite imagery, tracking aircraft via ADS-B, and visualizing signal propagation — all with full GNU Radio flow graphs published to the repository. The second module will focus on RF protocol analysis...
Free Stuff - April 2026
The April 2026 recipient for the Great Scott Gadgets Free Stuff Program is Juan Tejeda, applying on behalf of The Diplomatura en Ciberseguridad at UNTREF (Universidad Nacional de Tres de Febrero), an academic graduate program focused on training cybersecurity professionals in Argentina. We have sent the group a HackRF One to use in their program’s curriculum. Students will use HackRF One to understand radio frequency fundamentals and signal processing, analyze and reverse-engineer wireless protocols used in critical infrastructure and IoT devices, conduct ethical penetration testing on wireless networks, demonstrate vulnerabilities in wireless communications and help students understand real-world attack vectors....
Name that Ware, June 2026
The Ware for June 2026 is shown below:
This board is from my personal collection of “favorite boards” that I’ve collected over the years. A lot of old memories associated this one – both figuratively and literally.
I’ve received some feedback that gmail in particular is marking my email updates as spam. Not sure I have a good way to fix this yet, as the blog is also under heavy attack from automated AI spammers at the same time (to the tune of several thousand requests a day).
You’ll notice that the blog has no ads, so I also have no budget for...
Solution, Name that Ware May 2026
The Ware for May 2026 is, in FETguy’s words: “one of many large pc boards of a Rodgers Instrument Co church organ. The core memory was used to store and recall settings of the organ’s “stops”. There were 5 core memory boards in this instrument which differ in how many words were implemented. I photographed the largest one, which has 19 x 10 bit words, of which one is a spare, and then another word, I guess also spare, with no corresponding drive circuitry populated. So, 200 cores of which 180 were actually used.”
Here’s the unredacted version of the ware...
