Title: mikrocontroller code?
Post by: Login to see usernames on March 22, 2009, 18:02:23 pm
hi, i was wondering if anyone has built a pwm using a mikrocontroller? i want to replace the old lawton 555 circuit because it is not contemporary anymore and does use too much energy / is too big.

i am into learning how to program mikrocontrollers at the moment but if anyone has done a decent pwm system for something like an atMega8/32 i would have more time for other things.

I'm sure this answers most of your questions regarding pwm in uc's:

thanks alan,  today i finished my pwm system, which can be used with a duty cycle from 0% to 100% and pulse frequency from 0,25Hz to 8Mhz,


news on my project: I got my tubes with a gap of around 1mm and a bifilar coil, will measure the inductivity and capacity of both and with the help of that set the frequency to resonate.
at the moment i cannot get more than a few volts on the tubes, if they are not present i can measure nearly 500v after the transformer depending on the frequency, voltage dies in water as some people told before.

if i cannot get this thing to work i'll drop meyers completely, i followed the process described in his first patent which lay the foundation to his other work, if that doesn't work i'll let it go..

If it doesnt work , you have to research why it doesnt work and find a solution .

how many people are on this for years now and have not replicated it? the only ones who claim that they have results do not share how they did it so it's kinda obvious they didn't have success either.


the well documented replications do not work either, i'm afraid you were right about ravi. did not work.

try to find the resonant freq without the watercap (max voltage), then play with the dutycycle for voltage stepup effect

a coil alone has no resonance frequency.

or do you mean just no water in the tubes?

How have you wound the coils?

try to measure the voltage across the chokes without a cap and see if it varies when you change frequency (don't now if this is valid, but you can try it, need a hv probe). if it does, try to find the highest voltage by adjusting the frequency.
Try the same with the cap.
meyer said Xl > Xc, which means the impedance of the choke is max (no current, max voltage) and the impedance of the watercap is minimal (all current through cap) @ a frequency = no current trough coil and all current through cap (but amps are choked), try to look for these properties.

Just fool around :) you know what to look for, try not to get obsessed with trial and error to get bubbles, that is a step ahead, look for no current, max voltage and step charging by finding out the correct dutycycle (T2 < T1), T2 equals the timeconstant of the choke.

that is not how current works. in series, the current is the same everywhere. the inductance (and so the resistance) of the coil has to be higher for a maximum of voltage raise at the cap.

Q = 1/R * (L/C)^0.5
Vresonance = (2*pi*(LC)^0.5)^-1

the smaller the capacitor the higher the voltage raise will be.

yes correct, kirchoff current law, but current lags over voltage, don't know anymore how this lag correlate to L and C.

at a coil the voltage is pi/2 before the current, in a capacitor it's the current which is pi/2 before the voltage.

what happens when T1 is longer than the timeconstant? does voltage drop or does it keep its established voltage? I think latter is true.
voltage drops. the induced voltage in the coil is in opposite direction the current pulse is coming from. after tau (voltage waveform like a sin interval [0;pi/2]) is reached it's going back to zero, because it's acting like a normal ohmic resistance.

not exactly sure but it does not really make sense that the voltage is even higher, because of the opposite direction of the induced voltage.
while T2 (low), voltage collapses, when it reaches '0v' (after length of timeconstant) the magnetic field collapses and creates a second pulse (also with the same tc).
is this comparable to the next 90 degree of a sine? or again to the first 90 degree?
It's like the third 90 degrees.

in the image notice how the voltage is instantly at a maximum (x=6), that's the voltage pulse.

Great job Haithar , I see this was done without a diode , plz see the effect with a diode , investigate further , dont give up on SM .

this was only a picture taken from wikipedia, not what i really have. i don't own a digital oscilloscope or a digital system to record everything, only an analog one.
the waveform should be more or less the same of course, they used a diode to filter the back emf.


The voltage as seen by the choke would resemble the red current exponential curve.
How is the current from the collapsing field inhibited? By the second choke? Is it inhibited at all?
No, this was direct current, there were always Uo (5V) over the coil. The current is inhibited by the voltage caused by Lenz law, only for a short amount of time when using direct current like on the picture, but if you are sending in pulses of voltage there is a sharp voltage spike created everytime.
i guess the second choke helps to inhibit the current, but i still don't get why meyer connected them opposing each other.

now after you mentioned hyiq, he has quite an interesting setup. 23.2Watts for this amount of hydrogen could be more than you'd normally get.
Is this a coil after the transformer? The black thing in the middle which is connected with 4 cables, 2 from the transformer, 2 to the cells.

!Correction:
The voltage as seen by the choke WFC, doh

Yes, only at U0 there is 5v over the choke but ends up with 0v potential difference (5v on both sides), even with a dc pulse.


hyiq: It pulses 12v into a 220:14 transformer, amplifying and rectifying the voltage, no chokes in there.

no, chokes do have ohmic resistance too. there is always 5v potential difference with dc.

Potential drop (difference) over L with DC when current is stationary: constant current * ohmic resistance.
Don't you agree?

Yes, wait, if only an inductor is connected directly on a 5v dc powersource, there is always 5v difference

illustration:
Pulsed LR circuit with T1 =T2 = tau, left is voltage over R right is voltage over L. Left have the same peak voltages, V/div aren't the same.

of course this is right for dc.

illustration:

is this ac or pulsed dc? anyway you can see how the voltage at the inductor is before the voltage at the resistor, if you'd watch the current it would be the same everywhere in the circuit.

i measured the properties of my tubes and got my capacitance calculated. for all 4 tubes it should be 0,63nF, with my l/c-meter i measured 1,00nF, so this could be right more or less. unfortunately i do not know how to calculate the parasitic capacity of my coil which would make the whole capacity larger.

another problem i do have with my coil: i measured 1,23µH for each one with my l/c-meter. but i calculated a capacitance of now 25µH for both in series. however i do not know the relative permitivitty of my ironpowder core, a table here says it's between 300 and 3000. taking the minimum of 300 leaves me with 7,6mH. Ohmic resistance of the coil and the wires to the cap is 2,6Ohms.
As a dielectric constant for water i take 77, the lowest value too. All my caps together should have ~50nF while filled with water.

L,C,R bring me to a resonant frequency of 3,2kHz, but again i do not know. The µr factor alone could change the frequency tremendously.
