I have watched from 16 to 25. Tonight it was 22-25. I really like what I am learning from him. wow.

Did you find more in any others?

Ist,
Thanks but this is pure Faraday.
If you stop and start the transistor you are changing the magnetic field inside the toroid.
The quicker you stop or start it the MORE voltage you get out of it.
This is the stuff Tesla was undoubtedly calculating in his head. But it was not Tesla, it was Tesla using Faraday in a way the others did not.

I am looking forward to your experiments, but I completely disagree with the use of a signal generator that uses wall power.
I also think if you change from AA to 12 volts or anything else you have lost ALL ability to show a comparison.

So, getting rid of the battery that switched the transistor is exactly what I do not want to do.

Go for it, but I will only read and not do it until you can prove the same thing without the wall source.

Thank you,

jeanna

i do not agree with you on this jeanna ... 

but its ok ... 

i dont think you understand what im saying in my post ... 



if you do ...  well ...  congrats ..

basically im saying you need power to switch off and on the transistor ... that is all ..  what ever the transistor uses ... the OUTPUT IS FROM THE MAGNET ... TAKE THE MAGIC MAGNET AWAY ... IT WILL NOT PRODUCE ANY POWER  REPLACE IT.... IT WILL MAKE A SHIFTING MAGNETIC FEILD WICH YOU CAN TAP ... 


bla bla ...

im just guessing this aint for everyone .....



i also said NOTHING ABOUT PLUGGING A SIG GEN TO THE WALL.... 

none the less ...  im not worried ... i know fully well how to build WHATEVER I WANT TO BUILD ...

W

IM ALL MOVED NOW ...     and setting up my new shop ...  oooo the space ....   

i would expect to be BACK IN BUILD MODE BY THE START OF NEXT WEEK ...

@all

I just got a idea , what if we used a motor to pulse a toroid ...

One motor should pulse the dc , in a square wave , plus if we use 2 motor we can have 2 freq.

The same energy will pluse the toroid plus get free rotation ( could be reused ) plus no need for transistor .

Any idea?

OZONE GENERATOR ....  TESLA ....

I only found various videos he made.
What is the URL you're using to see upto 25 videos?

Thx

Don:

There is an entire semester's worth of Dr. Lewin's lectures, each 1 hour long, on Physics course 8.02.  I have seen like 40 of his lectures so far.  These are listed on the MIT website directly, or, you can find a few on Youtube, some of which are cut down to the 10 minute limit.  Others on Youtube are the full hour.

If I can find the link real quick, I will post it here, otherwise I will do it later.

http://ocw.mit.edu/OcwWeb/Physics/8-01Physics-IFall1999/VideoLectures/

This has 35 lectures but, I will try to find 8.02 as well.  (The above link is for 8.01)

http://search.mit.edu/search?__EVENTTARGET=&__EVENTARGUMENT=&site=ocw&client=mit&getfields=*&output=xml_no_dtd&proxystylesheet=http%3A%2F%2Focw.mit.edu%2FOcwWeb%2Fsearch%2Fgoogle-ocw.xsl&proxyreload=1&as_dt=i&oe=utf-8&departmentName=web&courseName=&q=Walter+Lewin&btnG.x=0&btnG.y=0

OK, the above link also has 8.02.

There is a lot of information in these lectures, and I think I even have more saved on my computer somewhere.  I hope this helps.
