Electronic is my hobby, but I am a "black smoke of death" hobbyist, because I am terrible at math. I liked you presentation as it was not full of technobabble and the use of the Osc made it visually understandable.. Thank you.
@wansolve289 He never was told exactly why. He has a new channel now he's "started from scratch". ""EDIT"" Hmmm, it would appear THIS channel is the channel that he's posting videos to now...hmmmm
Like others here I don't understand how this transistor is working. as a newbie my understanding of the transistor is as a simple switching device (i.e. putting a small voltage onto the base switches the current flow on between the collector and emitter. Don't you fry the transistor by putting 12v on the base? I can't see how this is adjusting the resistance to reflect the different loads.
I dont understand why collector has 16v and emitter 12v...if its becuase base is dropping those 4v through zener then we have to also put a resistor to the base?
Yes i had the same question. I also don't fully understand this operation. I'm trying to think of the normal operation of a transistor. After the transistor getting switched, the emitter stays 0V if the emitter is connected directly to ground. If there is some load on the emitter (like in this video) of course there should be some voltage 'left' on the emitter... But no one mention how this voltage 'arise'. But if you think that in normal transistor operation the BASE-EMITTER current (the switching current) is beeing ADDED to the collector-emitter current, you can make conclusion that this somehow SEPARATED current path (base-emitter) is dependent on the BASE Voltage, not the collector voltage... So the emitter would get the same voltage as the base but the base-emitter 'diode' junction droping 0.7V hence the 11.3V on the emitter (would be of course 0V if emitter would be directly connected to ground but here we have a LOAD). It's the same 0.7V drop as with a simple normal diode connected in serial... So again: Think the BASE-EMITTER current path as an independent path from the Collector-Emitter one like two parallel path.
This regulation is the most complicated, am trying to figure it out how zener is working with transistor and still not understand. Now am watching again and i belive is the relation between resistor(4v) and resistance from collector to emitter.
Man I wish I was smart enough to really appreciate this.
These tutorials are very very detailed.

I always find it useful and informative ❤
If I remember correctly, this PSU build was never finished before your channel was snatched by Google. Looking forward to viewing the complete series.
I’m new to the channel, why was his content snatched by Google?

meehn you are good
Thank you!
Great video

Finally i got the idea of the regulator.
It would be much less tedious to just buy a full-wave bridge rectifier instead of building it with four different diodes.
