JB Zero Force Motor - anyone building?

Minoly:

I apologize I stand corrected on the one miliampere current draw of JB's pulse motor.  When I watched the clip and heard that number I was struck by how low it was but it didn't fully register.  I was not up to watching the clip a second time to check his figure.  But like Brad said, that is simply way too low of a current consumption figure.  We all have probably looked at hundreds of pulse motor clips and judging by size of his motor and the speed, the coil size, and the sense of how much power is being burned off to do what it does, there is no way that his motor is consuming one milliamp at 12 volts.  It just doesn't fit.  That is an example of the "reality disconnect."

Here is another example of a "reality disconnect" that I mentioned about two weeks ago:  If you buy a hand-held digital stopwatch, or use one on your phone, the one-hundredth of a second measurement makes no sense - it's a lie.  A human being is simply not capable of having a reaction time accurate down to one one-hundredth of a second.  That digit is pure junk, and yet many companies that make stopwatches do that to sell more product.

You mention "perception of reality."  You have to decide what is cut and dried, and what is perception when it comes to electronics and pulse motors.  In electronics, it's much more of a cut and dried thing than it is a perception of reality.

Brad:

I forgot to say I watched your "zero force" motor clip and it was pretty cool how you improved the timing and cut through to the truth.  Using the coil discharge to light an LED to show the rotor timing was pretty neat also.  I assume you recall the trick that TK did on his MHOP series of clips to show the start and end of the ON time for the MOSFET (or was it a transistor?)

I know most of you from quite a ways back so I thought that I would stop by and add what I have done on this project.  I try not to take this stuff too seriously.  Life is too short.  Milehigh ----Hewey. Dewey. and Lewey say hi.  All of them are still around.  Patrick---the only reason I deleted your comment was because you have your YouTube reply button turned off and I didn't agree with what you said.  I sent you a PM explaining why.  Tinman ---many thanks for that old magazine link.  I grew up on Popular Science and Popular Mechanics magazines.  We had a book shelf full of them.  You are right that we should probably put this project to rest shortly and move on.  JimBoot----always a pleasure to see what you are up to.  TK----I did some research on that 'Slab Motor' and got totally lost. 
   I adjusted the timing on my motor to where it runs much better now.  Here is where I ended up:

I eagerly looked through the 1969 Science and Electronics magazine that Brad linked to.  I was especially interested in the back pages.  No Sea-Monkeys!?  What the heck!?

Nice to hear that the boys are all well.  And Maggie too?  lol

Attached are two pictures of their brethren.  If you have never seen the movie Silent Running it's really great.

And here is what I was really looking for in the back pages of the Science and Electronics magazine.  Okay I confess, you actually saw this ad in the back pages of the comic books around 1969.

It's a "PS."  That's Personal Submarine for you age-challenged.
