Chinese Oscillator and MOS FET Driver, Hardware experiment

[Jeg]

Guys, those videos are already in public. The Chinese engineer shows the basics in the construction of this very efficient inverter. He probably has hidden his real techniques which make it so efficient, but this is ok as it is not the first time that inventors try to protect their stuff and hide things. Nevertheless it is one more great project for doing your experiments.

ps1. I don't know if it is possible, but it might be better if Ramset could download those vids and upload them again under the account of Overunity.com

ps2. Comments are disabled in the attached videos so anything you need to say just do it here open-sourced and get your answer.

I could try to reach Stefan to see if he would do that ?


He seems not to easy to reach lately, much going on just surviving with all
The Covid issues!


Thanks for posting theses.


I will try to reach him , there is also another topic I was hoping to ask him about  .

Jed Hi, thats great concerning the video's  but any chance they can have the captions enabled ?

as that would be terrific as then we might be able to catch-on what he is saying 

Many thanks SIL

Maybe color or one of his family can make some key points clear ( quick summary)
I was doing this with a French member in Stela thread ... however Stela got strange with that topic
Removing his vids , so I am waiting to post again until we see if he really has some plan ?( I removed my summary before topic timed out with edit / time limit!



Regardless
We really do need more open source members from Asia !

Guys  I can't do it. I check Chinnese in the language option but after saving changes it returns again to English like i never checked Chinnese. So plan B for finding our assian friends needs to be activated!

I really dont know what someone could gain by winding the primaries this way, but you might have right my friend. It looks like two turns per primary. Probably he says how many turns we need in his video. I hope color will find it out!

Masterplaster, lancaV thank u guys! So interesting effect!!! It worths a try definitely!
