The Book with the most meaningful Impact on my Life
Posted on 2026-06-20I was recently asked which book had the most meaningful impact on me. I had to think about it for quite a while and went through various books in my mind. But then it hit me like a bolt of lightning, and the answer actually sounds like a joke: It was the mail-order catalog from Conrad Electronic (No advertising - I don't get any money from this company; it's just a factual account). Conrad is a German mail-order company for electronic components and more, founded back in 1923.

In the early ’90s, I was just over 10 years old and lived in a family that wasn’t really tech-savvy. A VHS VCR was already the pinnacle of my parents’ technological achievements, and even that one we kids programmed on our parents’ behalf to record TV shows. I already had a Commodore C64 myself and taught myself pretty much everything or got help from my older brother. My main source of information was the city library, which had both many older issues of 64'er magazine and books about my beloved computer. Furthermore, I was already very interested in electronics projects back then and had a Kosmos electronic X1000 experiment kit. I don’t know how or why, but one day I also had a catalog from Conrad Electronic in my hands. I assume I had my brother to thank for that as well.
Really? A Catalog?
Strangely enough, yes. That catalog had everything that interested me, everything I didn't know about, and everything that would interest me later on. It was like a window into another world for me. I thought it would be not only nice to have some pictures for this post but also to do a catalog time travel so I did some research and found a copy of the 1993 issue online for sale. I better not mention how much it cost me...
Electronic Components
Spanning over a huge portion of the total 1,000+ A4 pages, it listed practically every available electronic component on the market. From resistors to capacitors, LEDs, ICs, and so much more. Some things I knew, many I didn't. I could figure out quite a bit from the descriptions; the rest I looked up at the city library, which gave me more and more ideas for my own projects.
Electronic Kits
There were also many kits available for purchase. Through these, I learned about all the possible uses for electronic components.
Whenever my allowance allowed, I used order postcards to order new kits, or - and this was the absolute best - my mother would take me 50 km by train to the nearest store, where I would find myself in the land of my materialized dreams and could spend my allowance right there.

Computer Accessories
Only a few of my friends had a C64, so I had no idea what kinds of accessories were available. For example, I had no clue what a scanner or a light pen was. The catalog listed all these items. I also learned about the existence of other computer systems, what they looked like, how much they cost, and, indirectly, what you could do with them.

CB/Amateur Radio
Back then, I had no idea what CB or amateur radio was. I also had no way to participate in it. However, I was able to learn what it was all about, that you could also transmit data over it, etc. The whole thing didn't play a big role for me at the time, but it was interesting, and the memory of it also helped me get my amateur radio license in 2019.

So much more
There was so much more to discover, e.g., model building (RC cars, airplanes, helicopters, ships, etc.), hi-fi, tools, etc. I read it - and not just once, more on a daily basis. And it was not just reading, it was more like studying.
Was this really the book that had the biggest impact on my life?
Yes, really. It was truly like a window into another world. I learned an incredible amount from it and was inspired to take an interest in things and delve deeper into the subject matter. It laid the foundation for everything that interests me today (computers, electronics projects, amateur radio), and I had that foundation very early on in my life.
One thing led to another: I got my first soldering iron, learned an incredible amount about electronic circuits, was able to help my father repair cars (my job was the automotive electrical system), got an incredible number of ideas for things I could build (e.g., an alarm system for my room, a homemade audio mixing console), and learned how to repair things. Later, I switched to a technical high school, was able to do the electrical work in my own house myself, and so much more.
Of course, I could have learned a lot of this in other ways without that catalog. But did I have other sources of inspiration? Were there other ways to spark my interest in all of this? Probably not. Certainly not so early on. Keep in mind that there was no internet back then - at least not for me.
So: The book that had the greatest impact on my life was a mail-order catalog for electronic components, kits, computer accessories, and more because it sparked many interests, showd me what you can build and triggered so many projects.
