Just a final comment.  The EMF from the coil doesn't even have to dominate the EMF from the battery to get a difference in the intensity of the LED flashing.

Another simplified example:

Let's just say that the EMF from the coil is either +0.2 volts or it's -0.2 volts.  Let's suppose for the sake of argument this is related to the direction that the rotor is spinning.

Therefore when you add the battery voltage to the coil EMF voltage you either have +1.7 volts or +1.3 volts.

Therefore it's conceivable that you can have differing amounts of current flowing through the main loop when the reed switch opens, and hence different brightness when the LED flashes.

I would like to know if you found my discussion in the previous few postings open minded or closed minded.

Im using a pulse motor setup to drive my rotor to see if by doing anything on the other side of the motor, , has any effect in added acceleration. We have our reed, diode and coil, using 5 rotor mags 1/2inx3/8 n52 being held in position with my 1/2x 1/8 n42 diametrics installed in 1/2 in holes on the rotor. The rotor has 10 holes, but I wanna spread out, isolate any activity with break time. Then there is no dispute as to when things start and begin if I show a scope shot.

Using the leds as strobes on the rotor makes for visuals on timing. Nice. :]

With 5 in the rotor, the pulse motor and the other device are directly across from each other to maintain the largest distance possible between the PM and the device. And they are not doing their own thing at the same time so no interference, at least the best I can do for now. the biggest interference I would imagine is having the pulse motor kick  the rotor in the middle of the devices processes. A scope shot might be distorted with something like that. I think I covered the bases there fairly well.

Im running at low rpms at first.  the pulse motor at these speeds take a while to settle, so I wait.   

Right now I can produce very similar brightness levels, just like in the 3rd vid, by changing the direction of rotation. No Battery.  Just reporting. Did it in earlier tests also but just tried it to see it again. Feels good ya know. ;]
I want to neaten this up a bit and clear my bench a bit to do a vid on this. I think it is an important part of a new lesson. We will see. And it will show what I have been saying is true. It kinda brings out the bugs in others assumptions against claims before the goods are shown.  The difference between MH and I here is he doesnt have it sitting in front of him and I do.  Credibility will win every time. ;]

Also being that I have it in front of me and getting some good play time in, I understand some things that one that only sees pics and vids and stuff, without actual experience with the device right in front of them, things can get a bit hazy or distorted in view and thoughts. There are assumptions made and things missed.

Especially when talking about more detailed basics and direct descriptions, hands on right now. Any test CAN be done and REAL answers can be at your finger tips.
If you had 30 kungfu, harate, wing chun, jeet kun do  books and learned and practiced from them in a room by your self every day for 5 years, you most likely would get your but kicked when you went out to test your new self taught skills. Because you dont know what to do exactly, like the guy who has been in the ring many times in a 5 year span. Butt kicked. Fo sho. ;]

Anyways, Im trying different timings, pulse widths, rotor distances, led reversals for each test. Starting with the single reed at first. The dual reed in series really needs some fine adjustment capabilities. Working on that issue also. But man those pulses can be real short. ;]
Magnet adjustment is also necessary to get the same reed closure characteristics as all the others. I got it pretty good. Just slight shimming between the rotor mags. Details most dont think about. Even rotating the 1/2x3/8 axially makes a difference. Really. Mags aint perfect. Me either. ;]

Like I said, Ill get back into the battery stuff after. I think there is some interesting stuff to work with there also.

Whao, pages from MH.  Ill get to it tomorrow. Im beat. work in the morn. 11:24 pm

Read a bit of the first one. Do ya really thing that the gen portion has that much effort here? Your making me want to do the battery setup right now and do a vid.  ;]  Ill se ya tomorrow evening. Let me post to what you got so far before it gets to be too much to address as it takes too much time right now.  An apple a day. ;]
