Accelerator Pedal

(Lazer Accelerator)

Welcome , In the Section we introduce you to connecting to your cars exisiting digital electronic accerator pedal controlto a secondary motor controller which we use to connect to the electrolyzer to raise or lower hydrogen production on demand when you press or release the pedal. One of these controller was built into Stan Meyers GMS Unit which controlled the injectors and ignition timing as wellthis GMS unit it now replaced by standard or after market ECU's and one can add a lpg ECU and modify it easily. If you have a Car or motor motor bike with without this control you can easily and readily buy them now. The are not expensive and in ready off the shelf availability globaily. If you need help or advice aquiring these items please email me. Via form above. Please read on We will be adding these to the web shop. Sever builders have used these software controlled accerlerator controllers on already exisiting car stock digital electronic pedals to add the controller as a ideal way to raise or lower electrolyzer hydrpgen on demand gas production when they press the accerator and than reduce as they release the pedal. This is very basic and well developed technology which is off the shelf and available globally.



HHO /Hydrogen Electrolyzer Accelerator Pedal and ControllersLaser Accelerator Assembly(Standard Electronic Accelerator with Hall Sensor for switching Circuits for dutve speed etc for gas production)Can be done now in most modern controllers by the position voltage signal from pedal.) (20) Laser Accelerator Circuit (10) of Figure (4)


Which is a component part of Laser Accelerator Assembly (20) of Figure (3-10) uses a Gas infrared emitting diode (1) of figure (3-9) to trigger a SDP8611 Optoschmitt light receiver (2) of Figure (3-9) from quiescent state ( output logic high ... B+) (13) to on-state ( the minimum irradiance that will switch the output low) which switches or triggers the Optoschmitt (2) output to ground state (zero volts) (12) Blue Below is Left in but now obsoleteas off the self parts and fitted part do this on most cars, though you should review if when applying modern parts to ensure you have the technique matched and understand what is happening here. .(common parts now are Hall sensor on throttle body as less prone to failure etc) using similar moth and can be piggy back in same fashion, pick up sensor for engine speed are on trans and injector and euc directly so there is no time lag on cruise control etc between pedal commands.


 Billet Aluminum Throttle Potentiometer
 Price:  $195.00

Available Options:

  • Linkage:Socket and Ball (+$20.00)None

  • Model:Dual Channel (+$20.00)Single Channel


Uses a high quality OEM throttle position sensor (TPS) that is rated for 1 million full cycles.


It is then mounted to a solid block of machined 6061-T6 aluminum to mate with an indexable shaft supported by a sealed ball bearing and with an additional return spring and mechanical stops.

Hall Effect Throttle Adapter for Pot Box / Legacy PB-6
[Hall Adapter]

Price:  $78.00

Many legacy motor controllers require a 2-wire 0-5kohm variable resistance throttle signal, such as the Curtis with the PB-6. Unfortunately the potentiometers used as throttle devices tend to wear out and become unreliable over time, causing erratic vehicle behavior. 

To address this shortcoming, ZEVA created the Digital Pot Adapter, which allows the use of modern, reliable hall effect throttles,LIKE STANLEY MEYER INVENTED 


such as the Prius Pedal, with legacy motor controllers by converting a voltage to a resistance. 

Output resistance is floating and galvanically isolated from the input, to avoid any possible grounding issues. Outputs are high resistance (virtual open circuit) when powered down. This device is best powered from a key-switched 12V supply such that it is only on when the vehicle is running. 

The input side takes a 12V supply and has three wires (5V, ground and signal) to connect to normal 3-wire hall effect potboxes. The output side simply has two output terminals with variable resistance across them. 

At just 51x27mm, the adapter is small enough to mount inside common hall effect potboxes, or simply splice into a wiring harness. 

The DPA should work with any controllers requiring a 0-5kohm throttle. It has been tested successfully with Alltrax, Curtis, Kelly and controllers. 

It has come to our attention that this product is not compatible with Zilla controllers. 

Supply Voltage: 8-20 Volts DC
Power consumption: Approx 20 mA
Dimension: 51 mm x 26 mm x 8 mm
Weight: .4 pound
Origin: Made In Australia
Warranty Period: 1 year

GMS. It's definitely not a 555, for one he shows in the schematic that there are 10 connections, a 555 only has 8 pins. The reason for the logic gates and the capacitor are to convert the duty cycles of the incoming puts to a very short pulse duty cycle to be used as a trigger for the 74122 chip.


Once I finish putting this circuit together, I will show u guys what I'm talking about.--- End quote ---@ Tony:Thanks for being understanding...ive been trying to figure this control circuit out for a year or more...heres a question to consider based on the diagram attached..


.If Fig. (12 or 9xB) is the clock that times the whole circuit... that goes to point "G"Point "G" is the Figure 2 "GAS PEDAL" mechanical PWMStans design used a variable duty cycle to provide more or less hydroxy gas based on throttle positionpoint "G" becomes a 10% - 90% duty cycle at a given clock frequency which is sent to TWO outputs ( M & M1 )"M" goes on the top side of the VIC through fig 3 & 4 to create a variable voltage which is adjustable to provide a minimum idle speed at the low end and a maximum 12 volts at the passing speed / full throttle / 90% duty cycle setting"M1" goes to the bottom side through figure 6 and on to PLL / resonant scanner / pulse pickup / and the result goes to the bottom or "Ground" / "negative" side of the VIC coil through


Fig 5Here is the question... if the clock frequency at the input of figure2 is fixed and the pulse width is variable at the same clock frequency... wont the trigger from the NORs on fig6 stay at a fixed frequency regardless of the throttle positiontherefore wont the gating be fixed?I believe the gating of the signal going into or stepping on the PLL frequency needed to follow the figure 2 Pulse Width to provide a Hydrogen output range from idle to full W.O.T. ( wide open throttle)???SO the way i see it is this, there are 3 parameters at work in the system:


1. variable positive voltage tied to gas pedal from 1, 2, or 3 volts to 12 ( based on idle requirement) to top of coil2. resonant frequency based on pulse pickup being generated and sent to figure 5 via PLL ( not controlled by figure 2)3. additional gas output control based on variable GATING that "steps on " the PLL signal sent to figure 5 that is determined by Figure 2 PWM or throttle positiondo i have the flow chart figured out correctly?( see attached)


ok let me see if I can answer these questions for ya. Fig. 12 generates the gate frequency, lets say 500 Hz @ 50% duty cycle, which is then sent to fig. 2 via input "G". The duty cycle of this frequency will then be varied from 10% - 90% depending on the W.O.T. and rotation speed of the Distributor LED pickups. All these combined will determine the amount of voltage being applied to the Primary coil. This same frequency from fig. 12 will be sent to fig. 6 via input "B" or from fig. 2 via input "M1".


This 500 Hz frequency's duty cycle is then manually set between 10% - 90% duty cycle independent of fig. 2. This variable gated pulse is then input into the PLL circuit via pin 5 through the two NOR gates and if you notice at the 2nd NOR gate u have the resonant frequency being NORed will the gate pulse. The PLL will output the the resonant frequency at pin 4 which is then routed back through pin 3 and into the 2nd NOR gate


. The truth table for a NOR gate shows that you will get a HIGH only when both inputs are LOW. So the longer the gate pulse time is off, the more resonant pulses you will get into pin 5 via the NOR gate. This resonant frequency is steadily being match with the frequency from the feedback which is sent into the PLL via pin 14. Hope this helped answer some of your questions

AcceleratorThrottle Position Sensor

A throttle position sensor (TPS) is a sensor used to monitor the position of the throttle in aninternal combustion engine. The sensor is usually located on the butterfly spindle/shaft so that it can directly monitor the position of the throttle. More advanced forms of the sensor are also used, for example an extra closed throttle position sensor (CTPS) may be employed to indicate that the throttle is completely closed. Some engine control units(ECUs) also control the throttle position electronic throttle control (ETC) or "drive by wire" systems and if that is done the position sensor is used in a feedback loop to enable that control.[1]Related to the TPS are accelerator pedal sensors, which often include a wide open throttle(WOT) sensor. The accelerator pedal sensors are used in electronic throttle control (ETC)or "drive by wire" systems, and the most common use of a wide open throttle sensor is for the kick-down function on automatic transmissions.Modern day sensors are non contact type. These modern non contact TPS include Hall effect sensors, Inductive sensors, magnetoresistive and others. In the potentiometric type sensors, a multi-finger metal brush/rake is in contact with a resistive strip [2], while the butterfly valve is turned from the lower mechanical stop (minimum air position) to WOT, there is a change in the resistance and this change in resistance is given as the input to the ECU.Non contact type TPS work on the principle of Hall effect or Inductive sensors, ormagnetoresistive technologies, wherein generally the magnet or inductive loop is the dynamic part which is mounted on the butterfly valve throttle spindle/shaft gear and the sensor & signal processing circuit board is mounted within the ETC gear box cover and is stationary. When the magnet/inductive loop mounted on the spindle which is rotated from the lower mechanical stop to WOT, there is a change in the magnetic field for the sensor. The change in the magnetic field is sensed by the sensor and the voltage generated is given as the input to the ECU. Normally a two pole rare earth magnet is used for the TPS due to their high Curie temperatures required in the under-hood vehicle environment. The magnet may be of diametrical type, ring type, rectangular or segment type. The magnet is defined to have a certain magnetic field that does not vary significantly with time or temperature. In case of failure of the TPS operation the CHECK ENGINE light remains illuminated even if there is no problem or error in the ECU. It cannot be corrected by clearing ECU errors by running diagnostic software. In order to rectify the malfunction the TPS needs to be replaced by a new one.PLease See our Small Combustion engine Kit and our Vehicle and Combustion engine Conversion Perts and Kits.PArticulary the H2 Injector and the Low impedence adaptors.

Stanley Meyer schematic used variable voltage to primary coil. Laser Accelerator provided the variable input

  Ronnie Walker said because they had built all the Hydrogen Gas Management Boards or cards, thus allowing them to understand. Ronnie Walker said " I can tell you the voltage control goes from 2 volts to 10 volts. (on primary) The reason for 2volts is because Stan stated the voltage should never fall to 0volts to the cell. I've seen so many photos that are misleading because of things that are drawn on Stan's drawings of what people thinks. By building the gsm unit allowed Neal and I to know what exactly is going on. " Dec 31 2018 Further same day Ronnie said "my cell runs from 2 volts to 10 volts at .001 amps with no conditioning of the tubes at all."


See This Patent



check out part of the voltage control system for the primary here? J in the box is coming from another card which is toggled by the laser accelerator card.

Noted, thanks. I have one more concern with the DIODE on the secondary circuit which blocks and allow one way high voltages clipped wave/ pulse to feed to the water cell. That DIODE has another rating specification called REVERSE RECOVERY CURRENT/ COULOMB due to its PN junction capacitance, which will flow for a few nanoseconds or more during the immediate reverse bias. If I am right, it is worth investigate why NO GAS produced by the water cell.

 A22 is a voltage regulator and is only component I see that can perhaps provide a variable voltage outside the fact that the opamp is applying a square pulse to the transistors

i guess vdd is used to possibly use the system without a battery as to say for home production


There are a couple op amp based DC lab power supplies on the web...0-30v regulated
