A website dedicated to various topics that interest me. Retro electronics – primarily devices using vacuum tubes, forgotten old corners of Warsaw, playing with artificial intelligence, and other topics that strike my fancy at the moment.

I'm also trying to recreate the device descriptions I once posted on the now-defunct FonAr and Trioda website. These descriptions are not only mine but also those of my friends, primarily from the Trioda Forum. To enhance the site's content, I've included illustrations in various sections that I found in old books, usually from the 1950s, on topics broadly related to radio engineering (these are books or excerpts from books from defunct publishers, often without identifying the authors).

Where possible, I add information about the author to the drawing.

Due to the fact that much of the archived material being recreated is quite old, there's a certain inconvenience. Many links in the descriptions may no longer be current. Please don't hold this against me. I strive to be consistent and don't tamper with the content of the presented materials. I strive to preserve their original form. This applies not only to my own, sometimes "joyful" work, but especially to the descriptions of my colleagues, with whom I don't necessarily have the opportunity to consult, for example, on any changes. The only exception is the addition of a drawing at the beginning of some descriptions, the sole purpose of which is to encourage the potential reader to familiarize themselves with the description. The drawings are either the result of my struggles with Artificial Intelligence (AI) or come from my collection of technical literature from many years ago. Technical books and magazines occupy a significant percentage of my living space. Let them somehow repay me for the storage and dusting (that was a joke, of course).

Unfortunately, some of the ideas presented, which I find interesting, are judged as so-so by the local cats. Occasionally, the description provided here causes them to become highly excited. Positive feedback begins to operate, transforming the amplifier into a generator, as seen in the photo below.

And I think that's all I have to say about the archives for now.

Of course, I also post new information in this quiet corner of the internet, and in this case, I'm open to criticism. Due to its specific nature, the site receives little traffic. It's mostly visited by enthusiasts of electronic antiques, so I don't rule out the possibility of adding commenting to the site in the near future.

I'd also like to apologize for the typos in the text. Unfortunately, as I age, my eyesight begins to play tricks on me.

A small addition – I wonder what will come of this?
During a social gathering and a conversation about nothing, of course politics and social media, I was asked about my website activity. The topic of electronic device schematics and the famous (in certain circles of retro tech enthusiasts) 11-volume German catalog of schematics came up.

I have all 11 volumes, two separate editions from the 1950s.

 During the discussion, I was told that I certainly wouldn't be able to share the full set of schematics from this catalog (and there are many thousands of them). "What? I can't do it? Of course I can. It's just a matter of time!!!" So I gave in. I randomly selected volume II and started working. Each schematic needs to be graphically edited, as it's yellow and blurry after scanning. I've already added the first schematics to the table of contents of the aforementioned second volume of the catalog. I will be gradually adding to the schematic resources. It looks like the catalog will be complete in 50 years.
