No store-bought transistors for these guys -- they homebrew their own point contact transistors using a bit of Germanium from a diode. This makes me feel like such an appliance operator.
This video is in Polish, but The Knack is a universal language, and this guy obviously speaks it. Turn on captions, then opt for auto-translate to English. You will then get English subtitles and Bob will be your uncle.
I really liked this one. This fellow has obviously DONE this; his video is filled with both practical tips and theoretical explanations. He talks about the virtues of beeswax, and about how to borrow red nail polish to mark the collector lead. FB.
Here's the channel: https://www.youtube.com/@Marcin_Marciniak
In their next episode they promise to build a radio receiver using the homebrew transistors. That'll be great.
Thanks to Marcin and company, and to Jenny List of Hack-A-Day who alerted us to this.

But who is the fellow who built the homebrew transistor?

This is Alexander Zawada from Poland, one of the few people in the world who can make an electron tube at home. In September Alek will be a guest of SP Ham radio Technical meeting https://zjazdtechniczny.pl/
ReplyDeleteThank you Alexander. Can you tell us more about Alek? Bill
