First time I see a three-stage Darlington ...
And, by the way, first time I see such a weird on-off power switch 😄

Basically just a circuit that amplifies the induced AC in the copper antenna by roughly 3X to trigger the LED to light.

I have one of these built into my multimeter. Non contact AC detection. Great for not drilling through power lines in my house!

Удлиннитель: включение - I, выключение - O, а не так как в ролике! :))

Я правильно понял - удлинитель выключается, если нажать "Вкл" ("I") и включается, если нажать "Выкл" ("O")?
