i made this boost converter in my previous video part -1 . but there was a problem. the voltage was not stable it starts increase until 70-80V so it was problem. and that much high Voltage is not usable for anything. I'm in this part 2 i added feedback. and now its stable and the voltage can be adjusted from 6V to upto 60V . it works amazingly. i used The pin 5 of NE555 timer ic . because the 555 timer ic has internal OpAmp That is connected to oscillator. and pin 5 is connected to Non inverting output of OpAmp . and i used A NPN Transistor to Pull the pin 5 to ground and used a voltage divider to control output voltage. when the voltage increase on feedback the circuit tourn off for neno second or maybe less . and it somehow stabilize the output voltage to a level. now that voltage can be used to power many things. and this is awesome.

if you read these all . then I want to say its very hard to make these videos so please like and subscribe for more :-)
