10:00 Im pretty certain that that is the NTC thermistor. It decreases resistance when it heats up. It is there to protect FBR from inrush current of the big smoothing capacitor and as it heats up, the resistance drops which improves efficiency rather than having resistor which wastes ton of power
Love your Tektornix 2232. :) I had one a few decades back for a special project, and absolutely loved it! In spite of today's digital scopes, wish I had one now. Sadly every time I look, they sell for far too much compared to the more capable digital scopes that sell for $300 or less. :(
I have back massager that won't turn on. I have a few of them, but can I mail you a couple of them to see if you can find the problem and post it on youtube? I will ship it out free and you can keep them after it's repaired.
I have tried different power supplies and different uses for them, I have developed some kind of basic understanding what to avoid where, but I would like to see optimization ideas. To clarify: If i have to use switching psu with old audio equipment, how to get rid of the whizzing and how to get rid of hum, while using new audio equipment, that does not account for grid frequency hum. What happens when I use linear regulator directly after transformer psu or switching psu to try to smooth it out. Essentially it might be possible to provide rough voltage, that is regulators voltage drop plus roughness margin and the useful voltage? That could minimize the loss and provide awesome fast smoothing.
Take a 1000 watt high pressure sodium ballast transformer and chop out the secondary coil. Then you can wrap it with whatever secondary coin you want. I have 16 turns of 4 awg to charge super capacitors in seconds. Cheers
You are a very talented young man and it seems to me that you are learning very fast! That is also a talent - concentration! Behave of my family, I wish you great future, but mainly health, that is the most important of all! Listen to your body and meditate, because that will open your brainwaves into Stratosfere+
Do you have a PO box? If so, you should share it so people can send you cool stuff! Edit: Also, in most isolated SMPS they have a flyback diode across the primary to protect the transistor. Great video tho man!
@@kelleepackham4740 fcuk yeah! (Not sure if this is not tooo excited in your culture) was thinking he is maybe a little bit elder, but not too older - because corona ended this mision earlyer? I i just forgot about time? :-D never the less, Tanner, keep the good thing on going (both electronics and religion, maybe vice versa enumeration is better, depends ;-) )
@@TannerTech yeah! Your're back ;-) happy new year! Shall it be better then this one ;-) and tell us something in the new language you learned (if you were abroad) and mostly important: keep your attitude on going (on every scope you would like to)!
Wow I'm beginning to understand some of the things you say now! Haha! You're so smart :)
Really good intro for power supplies and their differences!

Are you sure? Thermistors are typically thermally coupled to the fbr. Also I have seen those on boards far away from FBRs
Clearly explained. I like the practical advises
Really nice! This informational/educational type content is really cool, keep it up!
Had few minutes to watch your videos - thank you!
No problem, glad you enjoyed it!
im Intrested in the christmas light setup :D

Is it safe to use a pc power supply for my zvs driver ?

Nice power supply.
Amazing
Thanks for this video
I like topic related to power supply
Thanks for the video!

Any idea, update on how is now our Tanner doing on his mision, when this covid stuff is going on?
He is back! This is a recent video.

Thanks man!!! Corona did end my mission a bit early, but it is great to be back!

Awesome explanation.
I missed his videos
You have a really nice haircut, did you do it yourself?
Yup...
Hey, but the emitter is 7v not 0.7 😛
15:40 that looks more like a constant currant driver🤔
Last time I checked them they were all sold out of pretty much everything
Hey, I just got a power supply adaptor for my old computer power supply, now I'm sitting there wondering how to make it handle 750watts 😂
Are you still alive bro?
first!
You are!!!
