PWM modification

[alpha-dog]

I did some MMW test today using one of the electrolsyers in my truck. I also was testing the current monitor/control circuit.

volts = 14vdc
amps = 40a
pwm = 2 P-channel mosfets
freq = 5khz
duty = unsure ( less than 70 % )
current control = max
stacks = 2
total plates = 13
MMW = 5.86
Lpm = 3.3 Lpm


volts = 14vdc
amps = 26 amps
pwm = same
freq = 5khz
duty = less than 70%
current control = adjusted to see change
stack = 2
total plates = 13
MMW = 6.57
Lpm = 2.35Lpm

Looks like I'm going to get close to my goal of 5Lpm. The current control doesn't work good enough for me yet. It is dry gas, the bubbler is about 2 feet higher than my reservoir with condensing coils. I measured with a homemade flow meter for accuracy and also a commercial flow meter. Going back to the drawing board now to make it better.

I'm not a hobbyist. My electrical knowledge is far too limited at this point in my life. After Nursing School, i may go to a technical school to open the doors on this.

But I am waiting on a Vada Energy Max 1400 Kit + a single vada EFIE which should arrive this week or the next. (will be doing an "unboxing" on youtube[dot]com/saintskyler)

Vada's PWM manufacturer has stopped producing units so I will be buying a MX067 PWM on ebay. I'm just hoping that the two units together will not drain too much from the battery and alternator on my stock 2006 Honda Civic LX i4 cyl. I've already gotten positive feedback from from Vada on the proposed setup, still waiting on feedback from the ebay seller, "arizonavideo".

What do you guys think?

I plan to merge the units in a clear acrylic casing with 2 PC fans (1 in, 1 out), some LED lighting, and total symmetry in mind. Once completed, I'll probably mount the case in the center of the back seat, facing forward "flux capacitor style".

Anyway, from hearing you guys talk about the technical specifications (which are greek mumblings to me) I thought you guys should be called "Water Hackers". It just sounds neat to me: To think that there is so much that the mainstream scientific community has ignored in terms of HOD fuel systems is mind boggling to me. I can't believe that we have not yet discovered the optimum frequency, spacing, amperage, voltage, chemical ratio, and combination of these per system.

Whatever it is that is optimal, wherever you HHO holy grail is, I hope you all find it, and it remains open source.

Peace.

Were you going to try my modification. Its a simple one. If you are not in that big of a hurry I and my friend ( an electronics engineer ) are going to make about ten of these poeple can buy. P-channel mosfets, current control, three or four units makes it versatile. Driver unit, current monitor unit and mosfet unit ( 2 fets in a unit, more than one mosfet unit can be used, N-channel or P-channel mosfets your choice). Easy to change it from 30 amps to 60 amps or even 90 amps.
We are working out all the details now.

This is the basic pwm driver I'm building

This is a picture of a P-channel mosfet switch assembly. It contains 2 P-channel mosfets rated at 80-amps and 300 watts each.

Here I've attached them directly on the electrolysers. This will keep heavy current bearing wires to a minimum length.

My twin electrolysers are currently producing 1liter of HHO in 12 sec.
