Кустарные вакуумные триоды Клода Пайяра. Часть 5. Конструкция лампы

Продолжим знакомство с работой современного французского энтузиаста-электровакуумщика Клода Пайяра [1], воссоздавшего в своей мастерской кустарное микропроизводство ранних высоковакуумных триодов — варианта легендарного ТМ [2]. Ранее мы уже рассмотрели его огневое оснащение [1], технологическую печь, контактную сварку [3] и ламповый аппарат ТВЧ [4], полюбопытствовали, чем Клод откачивает свои лампы [5]. С воображаемой лупой в руках посмотрим же, как устроен его вариант триода, чем он похож и чем отличается от исторических прототипов; по характерным примерам последних проследим часть эволюции этой выдающейся лампы.

Что на самом деле показывал индикатор частоты ЦП на корпусе?

Приветствую всех!

Когда-то давно тут уже рассказывали про кнопку Turbo и про замок на корпусе ПК. Самое время вспомнить ещё один неотъемлемый атрибут компьютеров тех лет: индикатор частоты процессора.

Казалось бы, это до невозможности банальная штука, не сложнее индикатора питания. Но всё оказалось не так уж просто и даже у этого устройства иногда можно было найти много интересного. Давайте разбираться...

Fanless Factor 101 Arrives with Qualcomm QCS6490 and 10GbE Networking

OnLogic has introduced the Factor 101, a compact fanless industrial system built around Qualcomm’s QCS6490 platform. The unit targets edge deployments that need wired networking, basic display output, and local inference acceleration in a small enclosure. The platform is based on an 8-core Qualcomm Kryo 670 CPU clocked at up to 2.1GHz, paired with 8GB […]

Free Stuff - September 2025

The belated September 2025 recipient for the Great Scott Gadgets Free Stuff Program is Ashen Chathuranga, a university student from Sri Lanka. He is working on a project involving the development of an open source satellite monitoring station and requested a HackRF One to conduct his research. He will also be researching radio wave penetrating materials for his university. Being able to assist students in need of equipment for academic research and goals is one of our primary goals for our Free Stuff Program, so we are happy we were able to help Ashen out!

Free Stuff - October 2025

The belated October 2025 recipient for the Great Scott Gadgets Free Stuff Program is Alex Barnes, who applied on behalf of Amateur Radio and Electronics Society (QUB_ARES) at Queen’s University Belfast! Alex has informed us that they are an academic society primarily focused on running regular educational events around radio and electronics. So far they have run lessons and training for their members to get UK Foundation Amateur Radio licenses, worked with a local Scouts group for Jamborees on the Air, and she ran a series of events last year where she demonstrated using an SDR and a few 433...

Free Stuff - November 2025

The belated November 2025 recipient for the Great Scott Gadgets Free Stuff Program is Srajan Sonkesriya from India! Srajan is currently working on an open source project where he is turning an Android device (Realme 5 Pro, RMX1971) into a portable RF experimentation and learning platform. His goal is to show that a smartphone, when paired with a properly customized kernel and open-source tools, can function as a compact RF workstation for students and beginners who cannot afford other common equipment. He says that so far, he has successfully built a custom kernel for Android 16 and added multiple patches...

Frigate with Hailo for object detection on a Raspberry Pi

I run Frigate to record security cameras and detect people, cars, and animals when in view. My current Frigate server runs on a Raspberry Pi CM4 and a Coral TPU plugged in via USB.

Raspberry Pi offers multiple AI HAT+'s for the Raspberry Pi 5 with built-in Hailo-8 or Hailo-8L AI coprocessors, and they're useful for low-power inference (like for image object detection) on the Pi. Hailo coprocessors can be used with other SBCs and computers too, if you buy an M.2 version.

AI is destroying Open Source, and it's not even good yet

Over the weekend Ars Technica retracted an article because the AI a writer used hallucinated quotes from an open source library maintainer.

The irony here is the maintainer in question, Scott Shambaugh, was harassed by someone's AI agent over not merging its AI slop code.

It's likely the bot was running through someone's local 'agentic AI' instance (likely using OpenClaw). The guy who built OpenClaw was just hired by OpenAI to "work on bringing agents to everyone." You'll have to forgive me if I'm not enthusastic about that.
