The Lee-Tseung Lead Out Theory

[chrisC]

From Wikipedia, the free encyclopedia

A solid state relay (SSR) is an electronic switch, which, unlike an electromechanical relay, contains no moving parts.  A photo-coupled SSR is controlled by a low voltage signal which is isolated optically from the load. The control signal in a photo-coupled SSR typically energizes an LED which activates a photo-sensitive diode. The diode turns on a back-to-back thyristor, silicon controlled rectifier, or MOSFET transistor to switch the load.

It is a matter of selecting the correct SSR for the Pulse Motor prototype.  It helps to have experts who are already familiar with the SSR.  Learning from square zero is not always the best strategy.

Any suggestions?

I suggest you remind old Tseung which pills he took starting about 2 or 3 weeks ago when he stopped posting. Those are the ones that actually worked and made him normal.
Now, perhaps he took the wrong medication again and then who shows up but you and Top Dork?

You have pointed out the the two important technical challenges:
(1) The sensing mechanism which is likely to be an SSR switch of some sort.
(2) The Computer Program for control

Tseung and Lee are theoretical scientists and not top-notch engineers.  It is time for the Engineers to shine,

You have seen the example of the Tong Po Chi device.  Tseung et al proposed that an unbalanced force can be produced from a closed system.  Tseung and Lee then proposed the use of non-elastic collisions.  Theoretically and experimentally, that was correct.  However, Tong Po Chi replaced the non-elastic collision mechanism with two unequal coils.  That is a much more practical implementation.

Tseung can still talk about the theory.  Let some top-notch engineers do the implementation.  The sensing mechanism and the computer program are within the capability of many top-notch engineers.  It is too late for the old Lee and Tseung to learn the basic electronics.  Let others shine.

The jeers will continue on this forum.  But this particular forum has not been wiped out for three years yet.  Using another Forum with the posts disappearing in 12 days is not the way to go.

Stefan has plenty of storage space. He does not need to delete useless info. (yet). Like I said, most of the stuff you guy(s) posted can be found in pre-'O' level physics bookshop, even in Hong Kong. So, that's not the reason .....

@ chrisC

Stefan does NOT have plenty of data traffic allowance. That is why we get this message:

"Connection Problems
Sorry, SMF was unable to connect to the database. This may be caused by the server being busy. Please try again later".

You speak of pre "O" level Physics. A principal  point of this board is that some of the Physics taught in schools is WRONG
or incomplete.

Have you learnt nothing, chrisC ?

Well Paul_R, on the contrary I think you're not really a internet savvy person. Do you know what bandwidth limitations are? These limitations dictate how much data can squeeze into a certain pipe in a certain time domain. Those messages tell you just that! It has nothing to do with how much storage there is. Comprehend e?

As to 'O'level boards not teaching the right Physics, I can see why you and Lawrence seemed to on the same level of perception and understanding. Perhaps you both studied under the same establishments. Did you study at Leeds or Southampton universities?
