THE (+) TERMINAL OF THE 4.7 mf capacitor MUST BE connected between the 1N5408 cathode and the 15K resistor... You can improve this circuit using a FAST DIODE (e.g. UF5408) instead the 1N5408... Greetings from Argentina!😂
I think I see it, when the circuit is first powered on the inductors polarity is reverse of the battery, that would put a negative base signal to the transistor turning it on, the field would build and the polarity would reach null after 5 Tau, turning off the transistor, thus letting the inductor collapse into the cap.
YES, because its current is LOW... BUT... BE CAREFUL! This circuit is ONLY for test LED and ZENER diodes! DO NOT connect to a dichroic lamp or similar...will make EXPLODE it! Greetings from Argentina😂
@@vernonbosshard9317 ticker? You meant hearth? Yes! It must be working fine, because If I can write you now, is because I'm alive... Greetings from Argentina! :)
The world's best teacher thanks

Which Is autonomy of the bulb with this circuit.? Congratulations from Argentina
Interesting rendition of a boost converter.
Nice video 👍 I want to ask, If the voltage is increased to more than 100V, will the voltmeter be damaged?
Yes it will
an again.. the Joule Thief 🙂
Thanks for the idea

Excellent.
I understand everything except the operation on the transistor switching.

excellent 👍
Thank you! Cheers!
😅 отлично
Отлично а схему можно?
You have changed the connection "+" of 4.7uF without mentioning it during the video!!!
You are right...Thanks for the advice!
Greetings from Argentina!😂
What is the output current?
The voltage of the cap over the load resistance plus the 15K is my guess.
Is it safe to touch?
YES, because its current is LOW...
BUT...
BE CAREFUL!

Hows the old ticker? working good?
