Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Hello

Congratulations! You have discovered how to make two LEDs glimmer just barely perceptibly, on a capacitor charged to 9V !

Now, if you can only make the LEDs light up bright enough on ONE VOLT to find the volume control for the soundtrack ........

;)

I posted these old JT videos in another thread, but they are relevant here now as well, so.... here you go again.

Making a simple PCB so that you don't have to deal with ugly pad-per-hole boards:

Mode switching, loopstick variable inductor:

Tiny current draw of microamps , with 2 LEDs so dim you can barely tell they are on, when the supply voltage is 2 1/2 or 9 or 12 volts, is one thing, well and good.

A draw of a few milliamps, when the supply is only one volt, with 24 LEDs bright enough to read by, or find the volume control.... is something else.

Я комментировал видео LASERSABER , где говорил что это можно улучшить!
Вот видео показывающее это, добавив всего один контур в резонансе к основной частоте , можно получить больше 1 :)


I commented on video LASERSABER, where he spoke of it can be improved!
Here is a video showing this by adding just one circuit at resonance to the fundamental frequency, can be greater than 1 :)

Я комментировал видео....
Спасибо за коммент. Приятно читать на родном языке - на Русском! Но... Я Ваши комментарии не видел! К сожалению...


Я немного по своему использовал ЭКРАНЫ! Я их использую как обкладки конденсатора в резонансном контуре коллекторной конструкции. В схеме этого нет.
Сейчас делаю новую катушку. Чуть позже будет видео и схема, если схема заработает лучше!


Далее пойдёт тот же текст, только через переводчика....





I a little on the used SCREENS! I use them as a condenser facing in a resonant contour of a collector design. In the scheme of it isn't present.
Now I do the new coil. There will be video and the scheme if the scheme earns better a bit later!
