Stanley Meyer / Dave Lawton Style Variable Frequency Pulse Width Modulator

Stan Meyer PWM front view

This is a true Stanley Meyers / Dave Lawton Circuit Design!

Don't be fooled by other standard pwm's that only control the frequency and make references to Stanley Meyers and Dave Lawton designs.

Advanced Features added to this machine augment the original functions of the unit!

This Pulse Width Modulator is built to the highest quality standards with built-in overheat protection. This PWM is designed to work with a Stanley Meyer type water fuel cell design noted for very low current draw and little or no heat.



According to Stan Meyer's claims his Hydrogen Cell releases the enormous energy of Hydrogen that is stored in regular tap water using a small current of 1 or 2 amps.

Stanley Meyer's legacy lives on. Despite his untimely death his detailed patents describe how to release the stored energy of water and produce at least 300% more energy than the electricity required to generate hydrogen from water.


This is an advanced version of the Stanley Meyer's unit. This unit uses the original design however this advanced unit has added many features not found on the Stanley Meyer's unit which include a heavy duty design that will handle more amperage. This unit is much more versatile and useful while still incorporating the original design into the construction of the unit. The original unit only being able to handle small amperage is very limited when it comes to experimenting beyond extremely light duty experiments.

The Stanley Meyer's unique design with mark space helps prevent the hydrogen or HHO generator from overheating by controlling the space or time of inactivity that is imposed upon the main duty cycle that is applied to the generator..

The second stage of the unit can actually switch the current off and on which in effect powers down the entire pulse output which feeds the hydrogen generator.

The heavy duty design of this unit will allow current draw of up to 15 Amps on lower frequencies. When used for experimenting on ultra high frequencies like the Stanley Meyer's Unit this can vary up to 250KHZ !

Used for experimenting and following up on Stanley Meyer's and Dave Lawton's patents and claims that huge amounts of hydrogen can be produced from small amounts of current this unit's amperage must be reduced to a minimum when using the unit on ultra high frequencies.

Works on 12v dc.

Carry out your experiments to the extreme !!!

Use the Stanley Meyer's / Dave Lawton unit on lower to high frequencies with high amperage and still have full control of your cell by using the unique controls on the unit.

You have full control of the Primary Frequency and the Mark space which is applied the hydrogen generator as well as Secondary Stages of the Stan Meyer's units unique design with Frequency Control and Mark Space which helps prevent the hydrogen generator form overheating by controlling the space or time of inactivity between the main output pulse.

Frequency Bandwidth Switch: Section A

The unit also has two bandwidth controls conveniently located on top of the unit. One control for section.

The frequency bandwidth switch can be set for any one of 3 preset frequency ranges. One advantage of using the frequency range selector switch is that you are working with a narrower frequency bandwidth. The bandwidth or frequency range of the pulse width modulator can be varied from about 200Hz (HZ is cycles) to about 250KHZ depending on the setting of the controls.

Frequency Bandwidth Switch: Section B

The frequency range switch can be set for any one of 3 preset frequency ranges. One advantage of using the frequency range selector switch is that you are working with a narrower frequency bandwidth. The frequency range switch allows you to do this in 3 steps because it breaks up the full bandwidth into 3 smaller segments. The advantage of this is that when you are tuning the variable frequency control you have more control and know the frequency range you are working in.

Frequency Control Section A

The frequency control Section A will allow you to tune thru the pre-set bandwidth which corresponds the bandwidth selected on the top Section A of the unit. Overall tuning range is from about 200Hz to 250Khz.

Frequency Control Section B

The frequency control Section B will allow you to tune thru the pre-set bandwidth which corresponds the bandwidth selected on the top Section B of the unit.

The Mark Space On / Off Switch

Used to turn on or off the mark space section located on Section B of the unit.

Automatic Shutdown Circuit:

This Advanced Stanley Meyer type unit is capable of running amperage of up to 15 amps at lower frequencies however high frequencies generate more heat and the amperage must be reduced to prevent damage to the unit. This unit comes with a built in safety shutdown feature which is designed to shut the unit down if it should detect overheating due to excessive current draw combined with high frequencies. Should the unit shut down due to this condition the status light will go out until the unit cools down. After the unit cools it will automatically resume working and the status light will come back on.

Ultra cooling quiet high output cooling fan:

On-board high efficiency fan which is switched on when the unit is switched on.

Off / ON Switch

The off / on switch is located on the front panel and is incorporated with the mark space adjustment on Section A side of the unit.

.Power indicator light:

Power indicator light is red and shows when the unit is turned on.

Status Light:

You can monitor the operation of the unit with the status light including the cutoff variation times. Should the unit go into shutdown the status light will go out.

Durable Aluminum Case

Durable high quality lightweight aluminum case.

Compact light weight design

approx measurements: Enclosure 4"W x 2" H x 6D

Fan and controls mounted on top add 1" height
