    DiD you get a 5 k oscillator to use with the Megura throttle so you can connect to the JS Monster driver IT must be one that uses a 5K ohm input

    I finally found some 40v regulator here on EBay

    Kogs,

    Thank you for finding parts for me. I appreciate your help. Is that all I need to connect my throttle?

    Keep it Clean and Gren

    To use the JS Monster you need 2 other Items
    You need a drop down 40v down to 12v power Regulator I purchased one on EBay but it seems they are not there any more

    Also you need a 5k pot oscillator that is set to give output duty cycle 0 to 100%

    On the Oscillator you should have 6 connections
    1=Pot low, 1=Pot wiper , 1=pot high
    1=the 12v+, 1=Negative, and 1=Oscillator output

    Now the Pot is replaced by the Magura twist hand throttle as it is really a 5k potentiometer
    the connections are the:-

    Blue wire goes to the high side of the pot
    Brown goes to the wiper
    Black goes to the low side of the pot

    You set the low and high by testing the output from the oscillator with A DMM set to more than Duty cycle
    Then place the Black probe to the negative Common and the red probe to the output of the Oscillator the Magura is set that when it is at rest the duty cycle should be 0%) and when you twist it the Duty cycle increases till it reaches 100%(mine only goes 0 to 99%)
    If the Magura is reversed that is at rest it reads 100% then just exchange the Blue and the Black wires

    The Monster that Dana has built is really a 4 times JS Monster that I believe has one input from the Oscillator But you will have to ask Dana where the connections go and what the voltages are as I think from memory that he upped the voltage to the driver as he was using only one auxiliary input higher than 12v so as to cater for the voltage drop over the 4 Monsters

    If you can not find one There is a few on the forum


    I hope this helps

    Thanks, you was so kind, that repeat the pics and explanations, that you
    already posts for all of us and i already saw this version also,
    i was asking again, because i really dumb and goofy to understand sometimes not native language,
    and i trying formulated as simple and uniquely, that i can grasp.
    Sorry.
    thats why i again not sure, and outline the wire on your pic,
    that i think lay on top,
    ami right?

    sawa
    Yes, that is right, Sawa

    i missed that.
    i use oscilloscope for everything in this finding.
    So i keep going to tune with pulsewidth.
    Also to be sure about CW/CWW/N/S:
    all we know the most popular screw thread named right thread (used almost everywhere,against left thread, used sometimes
    in places, where right thread can unscrew by itself (left bycicle pedal))
    so if our coil looks like right thread, then where to put +, there will be the North, right?
    Regards sawa.
    Hello Sawa,

    For windings of Coils I use "My Right Hand Rule"...

    [IMG][/IMG]

    Just look at Left side coil and hand, notice Top wire goes to the Positive (+) Commutator on top, so Positive "signal" runs toward my fingers tips, then my Thumb aims to North Pole.

    That gives you the way to hook up/wind your static coil.

    By the way, remember that if you use bifilar wire (dual strands) of like 18 awg (American Wire Gauging) and keep above One Ohm (I rather stay at 2.0 Ohms) you will get better results.

    If you are using a solid steel core for coil...then test by holding a CFL (or could be a Neon Bulb) with your hands, touching only the screwing side...then touch the steel core with the other end tip...and watch it while you put up/dial up pulses...

    Take care

    Now on circuit with coil and load(KOm or CFL) i only see with scope, (connected to G of mosfet) - mutilated meander -with very high very short pulses on the moments of switch OFF the mosfets; it seems RE draw back to circuit instead of going through diodes to load.
    on the same time the another Scopeprobe, connected to load(w/o ground) - repeate the form of input pulses in general.
    i thought - it should be opposite to input because of diodes.
    Hello Sawa,

    This circuit is a PWM Controller, as almost every controller out there for regular motors are Pulse Width Modulators.

    If you read Gary's original circuit designer...He tells that Duty Cycle is what is changed here.

    The reason of confusion raised when we used Digital Multi Meters that read Frequency and added to Input and Output...then we got Hertz readings...If You do that, you will also get the two different Pulses from Input and Output on DMM...where Output is greater than Input.

    I found a few pictures on my cell phone while I was making the rotor. I can upload them here, but it says my limit of 3.4 megs is full and I cant seem to delete old pictures...

    pulse width or freq lure the witch?

    The POT is very sensitive tuning...must go very slowly, and I installed a Vernier Dial to make it even slower and more precise.

    And actually that circuit IS NOT MY original concept, I got it from Gary at CHEMELEC (A great guy in case you need to order parts or already made boards, he is got very interesting projects, etc)

    Here is the link to this particular project where He explains in detail..
    A Pulse Width Modulation Control
    .....
    .....
    And Yes, You could use A different circuit, However, I do not recommend to go and buy ANY ready to turn on Controllers or Oscillators...because simply...do not work....the existing PWM Motor Controllers are designed to Rush In and start at 900Hz to 1000Hz...NOT GOOD!


    Ok the main specifications on Wave is to be ASTABLE ...
    The second and to me the Main ONE, Is that it starts from ZERO, ONE, TWO...SO ON HERTZ PULSES..

    Thank you for you time, UFOPolitics!
    Hope i do not irritate you too much, but i am confused,
    does this circuit with pulswidth lure REwitch, and with exactly this you light a bulb in a water, or i need another one,not mentioned in this thread, that doing change freq from very low hz?may be low hz means low hz on the cold side while on the hot side is fixed ~500Hz and slowly change from 50%dutypositive down to ~10%...
    on one hand you recomend to use this circuit(if i understand right) and to change freq from low hz, on another hand you agree that this one regulates the Duty Cycle, not Frequency.
    i understand about attached coil, but not quite understand where to attach: to pulse width modulator or freq modulator.
    If my question looks strange, do not care, may be i did not understand enough and only spend your time;
    i am very impressed of all you are disclose here and do not want to annoy you.
    Regards sawa.

    Probably it was too far ago and you do not remember, but if you do,
    please, how do you yourself actualy feeding mosfets to draw out the witch to light the bulb in the water :
    1.with one of this circuit based on 555(4 or 6 mosfet)
    (A Pulse Width Modulation Control)

    or

    2.signal generator.

    I am asking, because after playing with this circuit(pic from post 2676), i doubt, that it can produce freq 1hz. Also on the site above, the description of this circuit explain, that it works with changing pulswidth and constant freq about 500hz.
    After i disconnect oscilloscope from pin 2,6,7 it is really rotating the pot does not change freq much, only - from ~400 to ~500, but pulswidth changing- significantly.
    also, calculation freq based on R1,R2,C(R1+R2=250K,C=0.01)
    never produce freq about 1hz.
    (for example here(it is on russian) [ekalk] 555 в режиме астабильного мультивибратора)

    I have signal generator, but afraid to burn it quickly, that's why i asking.
