The Vic Matrix Set
When Stanley A Meyer Installed the Voltage intensifier Circuit into his vehicle, he had several controls in it , this was the most advanced version Stan had over 12 version of the VIC voltage intensifiers Circuit this one was the final and most complex, In 1994 to 1996.
Since than a lot of the Ems Ecu EGR and Valve , pedal controls are now standard on vehicles.
and common place.
So we pull out the Vic Matrix just the Water fuel Making part and show it here.
Here is solid state auto cut out relay protection for the

Vic Matrix Replications
Built holder for boards from 2 shelf boards as laying them out on table was taking to much room. Wiring was mostly to route power to each board. I left enough slack in wires so I could pull each board out to check it with a scope.
I was glad I did as I start to do system tests to see if everything was still working, I found I had moved pot settings and needed to reset them to match setting from my initial testing.
The scope shots in my test reports were very helpful in doing this.
Hopefully with this setup I can just connect the coils to connection strip on the end and continue testing. One thing I do not like is the 2n3055 mounted on the leg make that whole leg to be at +12 DC.
I need to do something about that. I am still working though checking things, but I did find another issue I though I would report. I started on the analog side and was working my way though resetting the pots and I am getting the results
Pictures below. Front and back of finished boards mounted power comes in on left through a 12-volt connecter and there 2 LM317s one for 10v and on for 5v that feed bus bars on back.
Common ground through out system. Boards powered from the bus bars. Bus bar on the right will connect to primary and feedback coils.
Continued testing with check the High frequency side. Verified boards are working and then checked inputs to both sides of primary coil.
Channel 1 Yellow is from Cell Driver K4 and Channel 2 Blue is from Voltage Amplitude Control K9 on Analog side. Both scope probes are hooked up prior to diodes as I wanted to see input to primary coil.
At this point I am just using a 10-ohm resistor to provide a resistive load.
The first picture shows this test setup. As there is are no coils in the system, I have hooked the output of K21 (G) back to what would be the input (H) to the board from resonance sensing pickup coil and Pulse Indicator Circuit K14 (black jumper in picture).

Vic Matrix v2 update 24 Dec 2020
Capacitors arrive today so I finished installing them on K8 attached picture. I have made 2 changes I used 2N3904 and 2N3906 for Q2 and Q3 as I had them. They are what I used on by test board. Rather than take apart test system I am also make new front panel for each board. I have all the front panel parts for this one. Still need to make the front panel so I can mount the parts and make the wires. It is nice that for this board all the front panel wires can go to new connections to left of the board. I plan to use screw connectors there. For my initial testing I will just use screw connections on break out connector.
While I would like to test on VIC Matrix board I am still waiting for the 37 pin sub-d connectors for that board. So I will do initial testing with a break connector as that is how I am currently testing K2 board. This way I know it works before installing on VIC Board. Nice thing about these connectors is I do not have couple pins.
Also all you need for a card extender for the VIC Matrix and board is a standard 37 pin straight through cable I purchase one but easy to make with ribbon cable and a couple of connectors just needs to straight through.
board was fully functional with exception of 4x switch but tested that with jumper as is just a switch.
Note: The switches in picture have a narrower profile as lugs are on back instead of side.
The were new this year at least I did not see them when I bought switches a year ago
Installed Chips and checked that they all work. Other thing I wanted to verify was what is hooked up to the boards output pins 1-4. There are 4 landing pad labeled COM on board. There are no numbers but if they are number 4, 3, 2, 1 with 4 closest to COM you use these to set switch go to which output port.
Board Output pins On-board Pins for Switch Com
Pin 1 - is G to K11 3
Pin 2 - Q to G10 2
Pin 3 - B to K3 1
Pin 4 - C to K3 4
The above is fixed, what can be changed is where you land the common from the 4-position switch. For example, I plan on initially only hooking up 2 switched but I what them to be B and G so I will land switch commons on COM pads 3 and 2 and label front panel to match. You can use any set of points for the four inputs to switch where you land Com is all that matters.
Picture is the K2 being tested to determine the above. New front panel is behind. You can see the new switches I plan on using just have not wired them up yet. Just found these Electrical Buddy 2PCS 1 Pole 4 Way Rotary Switch with Knob.SP4T 8A/250V on Amazon $10 for the pair
That looks right nice and clean too. The board I have matched drawings I marked up. I have already cut the traces on it (Plexiglas scoring tool make cutting them easy). Once I added 3 jumpers (I put one on pin 7 to resistor as well meter read open circuit.) I can now get frequency and can adjust it with pot. Have not finished checking rest of board yet. I still need to connect 4 - position selector switches was waiting to very 555 worked first.
I should get that hooked up later today and still need to put other chips back on board as well.
37 Pin Connectors for VIC Matrix card came today and I had the screw connectors so I installed them. I also tested the screw connector interface to 37 pin connector for K2. You can see interface test card in last 2 pictures. Just need to make wires between K2 switches and I will be ready to test that board installed in VIC Matrix. For now I will be using the screw connectors to power K2.
I recommend putting on screw connectors first as the a shorter that 37 pin connectors. I snapped screw connectors together then installed them as group. Then flipped the board over and soldered them. These are a tight fit so you do not have to hold them but with board face down on flat surface it gives you a solid surface to work on. The 37 pin connectors are a loose fit so I started with 3 one at each end and one in the middle then flipping board over again the flat surface held them in place while soldering. Ten just filled remaining connectors one at a time.
Connected 2 4x switches and installed K2 on VIC Matrix board. Provided 5vdc from external power supply. Checked both 4 position switches with o-scope and they work correctly. I wired one switch to provide B output to K2 and the other to provide G output to K11 and verified that the signals were on the screw connectors with those labels. I set the frequency with the trim pot. I will glue that to the front panel. I prefer the trim pot as it gives me better control and I have found I am less like to change wrong one. So K2 is now fully functional. (I left of the other 2 switches off on purpose).
I had verified 5V and ground connections before installing board and used screw connectors by power card to provide power to VIC board so I can also verify the safety card does work as well.
I am in the process of building a holder for the VIC Matrix card and front panels similar to one in back of picture which hold my breadboards. Already have the 2 shelf boards mounted to corner bracket just need to make mount for VIC Matric and drill holes for front panels.
I like that you have the Safety Jump Card on
I hope you will test and use the power rails on the board eventually as you gain trust in them ,
as it should help ease the transition from the wire birds nest we designed it that way,
The Screw Connectors will allow you to test and jump wire if there is a need ,
we tried to allow space and blank pins on each db37 position on matrix to advance each card version
as if traces for any new things not on matrix than new areas on that card or cards progression go out screw terminals in the empty spots
safety card is a good example of that
Actually using power rails now to feed in power from left on screw mount by power card. I really like that feature and one of the reason I started building card so quick. Having build my test circuits on breadboard I is very nice not having to deal with all the jumper wires I do plan on build power regulator card just having gotten to it yet. Will need it for 12v and 10v anyway will still use power supply as power source. From my testing it looks like there are two separate power paths on left end of the board one for on board and second going off board. A label showing this would be helpful.
yes we built in up to 3 power paths so we have redundancy at least 2 ways on board
if you blown up power board you can jump to the back up on matrix from 2 or 3 spots
this means we can scale take risks and physically cash it and mostly likely it will still keep going
worst case with a jump to screw terminal
ideal when it is your source of fuel
I updated doc again to version 2.4 added information in K2 section about where the COM pins on K2 go to on 37 pin connector and screw connectors. It also explains briefly how to hook up switches to K2. This is the same information I provided in post above just wanted to capture in document before I forgot.
I populated the K3 board and went to order couple for IC I did not have and found DM74LS21N and DM7432N are both discontinued parts.
They both have replacements I updated attached BOM to show that.
I also corrected 2N3094 to be 2N3904 which is what I used on my test board and Ronnie had in his BOM for this board,
I believe this was a typo as 2N3094 is a not a transistor.
Both the discontinued chips are standard logic devices so any version of the chip should work.
Also should indicate direction of diode 2N4007on board.
Should have parts in a few weeks and will and stall and test board.
Made some more progress. Used 317 devices that are complete (all cap and pot on small board) to provide 10V and 5V to VIC Matrix. Combined with Power Supply supplying 12V I now have the inputs I need to continue testing. I Installed K8 to test it. First noticed no digital input on M. Fixed this by putting a jumper on screw terminals for K11 Jumper from G from K2 to M1,M2 on the screw terminals. On my test system I just used output directly from K2. The jumpers do the same thing.
Did not get desired results. Went to check using my trouble shooting steps from K8 write up. I needed to know where test points I used match the PCB layout so used traces from K8 above. I found 3 problems with the layout. All three transistor have problems. If you want to match Stan's circuit the following changes to labeling should be made. The circuit traces appear to be correct.
Q2 should be Q1 a 2N3906 that faces down PNP (power into emitter)
Q1 should be Q2 a 2N3904 that face left (2N2222 should also work) NPN (ground into emitter)
Q3 should be MPSA20 that faces down PNP (power into emitter)
NOTE: all the collectors and emitters are on the wrong sides.
I will make changes on my board and continue testing.
I will make changes on my board and retest.
Making changes above fixed problems board now works properly see scope shot below. Second picture is front view of panels for K2 and K8. Third picture show power input to VIC Matrix. You can see the two 317 devices mounted on back left leg I am using to set 10V and 5V input and power supply to left that provide 12V. All 3 go to screw lugs in front of the power card.
I have noticed that without external wires running all over the place signals are cleaner. I have the frequency set to 41.67hz yellow trace the same value I have been using in my other testing. Blue trace is the analog signal generated on the board it is set just above the minimum level where clipping occurs. This can be raised with idle control. All the front panel controls work. Missing test jack (has not come yet) but switch works as probe is on switch output. All front panel wires for K8 go to screw connectors.
Here is the picture of K8 with transistors installed in correct location and correct orientation and correct labels should be. Second picture is my hand drawn version of Stan's circuit that I built test board from.
I included it as it has pinout for the transistors and NPN and PNP labels.
I used this to check board as the power and ground lines showed me the correct orientation of the devices on the board. Easy to find pin location and diagram just search on internet like this (2n3906 pin locations).
Note: For this board the base center pin needs to be bend toward the flat side of all three transistors and the board diagram should have the flat side by the base pin.
I do have the K11 Digital Means board. I plan on building it but have not needed it for initial testing.
I have noted the inversion I did to signal in my test thread. In my test system I used one of the unused OR gates on K2 to invert pulse and fed that to K8 as signal gets inverted every time go through a logic device.
I only noticed in combined signal going to primary coil as ramp up was in space and not in the pulse. NOTE: It is also possible signal got out of sync when I add changes to Stan's circuit to raise gate signal from 5 volt logic level on K2 to 12 volt logic level need by K21. I plan on checking if the boards corrects both these items.
Picture below, but I am using jumper as signal to K8 comes from Digital means board K11 which I do not have.
So I am just routing the G signal from K2 which is an input into K11 so it shows up on K11 screw terminals to the K11 M1,M2 output screw terminals.
M1,M2 are the inputs to K8 and K3.
So by doing this I have these inputs without the acceleration function.
When you add K11 or replacement you just remove jumper.
This is good enough for my testing as I can manually adjust gate on K3 and frequency on K2.
I did the same thing with my test system but just routed signal directly from K2 as I am using wires in that system. Do not recommend changing anything on VIC Matrix board for this.
NOTE: This works for initial testing but I did find when I went to combine the signals cross the transformer I needed to invert input to K8 see signal reference falling trace on K8 circuit diagram. M11 provides M and M inverted you just choose one you need.
Just used the old card picture because I was using the circuit traces with pictures posted earlier in this post I could see new board had same same layout. I had copied them into a word document so I could get them all on screen at same time. Just did not think to put markups on new card.
The 317 are great others were talking about the chip to generate 10V so when I went looking for it I found these it is cheaper to buy these than all the parts - 5 of them are $7 on Amazon. Just type in LM317 on Amazon site. They will also do 12V but need to supply at least 14V for it to work.
Stanley A Meyer K3 Gated Pulse Frequency Generator New board testing on VIC Matrix
I decided to compare K3 board traces against the K3 schematic before I tested it as I have everything installed on board except SH74122n chip. It looks good couple of label corrections
The 2 Q1 chips are labeled 2N3094 them should be 2N3904.
While correcting those it would be helpful to label GND and Signal on test landing pads (GND is closest to board edge).
The Cell ON/OFF needs to have GND going to switch as closing switch connects the circuit to GND which turns off cell. I used a simple on/off switch and connect it to the GND lug on the Test Point on the panel. Then turned switch upside down to match label on front panel with up being on and down off. A cleaner fix would be to do this connection on the landing pad. See circuit trace below to see what I mean. Adding this wire is the only change I made to get card to work and I did that while wiring up the front panel.
While I am still waiting for a new SH74122N I wanted to test board, so I took the one out my test K3. I can report that the board works. I did test all the front panel controls (still need to label and mount the trim pot) but as I mentioned above the only thing, I change was to add the missing connection to GND on the Cell ON/OFF switch which I did on front panel. NOTE: Input signal is from K2 and K3 is in manual mode for these tests.
I did notice that the [A] signal on the test point was not what I expected. It was a square wave at 5-volt levels. It does change as expected with the pot controls. See picture K3 test point Signal. I also checked [A] on screw terminal and it is the same signal but at 10-volts, which is the level required by K21. I actually expected this as VEE pulls it up and powers the LED. See picture K3 [A] on screw connector. Note: ( [A] is the basic gate frequency and duty cycle used by the rest of the system. If it is not at 10-volt level it will not trigger the chip that combines the gate with the high frequency digital signal. If gate is turned off no digital signal will be sent to the cell.)
There are a few other chips on the board that are not in original schematic and they use the [A] signal that goes the test connector. The [A] signal gets combined with another signal that comes in on one of the board pins. The additions chips AND the 2 signals and route results back off on another board pin. (This means the combined signal can never be larger that gate pulse, but it can be smaller and is at 5-volt levels).
Having the 5V level signal on the test point is not a problem as what is being checked is gate information mainly frequency and duty cycle. There just should be a note some where it is not exactly the [A] signal being sent to rest of the system.
Added picture showing new K3 front panel being tested on VIC Matrix.

I wired the version of VIC that I currently have to get ready to test when I get the missing Capacitors.
Most of the wires coming out of the VIC connector are in the new 37 pin connector on new version of board.
The 5 wires going to coils will still be needed.
I have modified this board to make it as close to new version as I could so I can verify changes works as expected.
The first picture shows the connections. I am using the separate daughter board and I have not mounted it as I may need to take VIC board out to install capacitors and as the connections to daughter board are hard wired this will allow me to move it as well. The connector strip on left will be used to connect to coils.
I have same connector on my test system so it will be easy to move coils to this system.
I have not yet connected the wires to it, again as I may need to disconnect them when I install capacitors.
(My test system is behind in the pictures.)
Second picture I zoomed out to show more of the system.
Third picture is the back view of the VIC Matrix and boards I have completed.
Other boards installed have already been tested and are working. They will be used in testing the VIC.
Throttle Control Thoughts
I have reached a point in my testing where I want to be able to better control the voltage level of the analog signal.
So far, I have been using the Offset control in L9 (Voltage Amplitude Control Circuit).
While that works it does not provide a good indication of actual offset level.
While Gain is another control, I believe its function is to set an upper limit. Looking at the front panel both controls use locking pots so it apparent that they are intended to be set then not changed.
Today I took another look to see what Stan is changing in his circuits to change the signals.
He sets a reference signal in K2 (Variable Frequency Generator) that goes to K11 (Digital Control Means) this signal is used to generate a new pulse train which varies based on the need for gas, throttle control.
I believe what is changed is gate size (have not built circuit to verify this for sure but gate side is one means of changing gas production).
The output of K11 is fed to both K3 which produces the actual gate base and K8 which produces the analog signal.
The pulse frequency does not change but duration of pulse is tied to pulse size from K11.
K8 is triggered on falling pulse to keep analog signal in sync with gate.
With this you would think the Digital Control Means is the primary control for gas production, this true within limits.
The limits for actual gas production is controlled by the Gas Feedback System as it has override control of the system to keep too much gas being produced and it can also produce more to keep pressure up even if Digital Control Means does not request it.
It does this by controlling both the gate size and the analog voltage level as both control the amount of gas produced.
It does this by raising both if more gas pressure in cell is needed and lowering both if gas pressure in the cell is high.
Now there are some restrictions in the process.
Lowing Gas Tank Pressure
While it can reduce the level of the analog signal this does not override the level set by throttle control. But the gate size it produces will override the gate size produced by Digital Control Means system.
The reason this is true is the 2 signals are merged in K3, Gate Generator, using an AND function so new gate will be the smaller of the inputs. The smaller gate will produce less gas.
Finally, if pressure in tank is still too high the Gas Feedback will send a signal to K3, Gate Generator, to turn off cell.
Raising Gas Tank Pressure
If the pressure in the tank is too low the Gas Feedback system can ask for more gas to be produce than being requested by Digital Control Means.
While it can increase the gate size this will not override the size set by Digital Means, again the AND function set it to smallest size.
But the voltage level on signal [j] can be increase and this will override the operating level of the running value for [J], as long as it is higher.
Dan a couple of things from the above.
Not positive about base frequency not changing.
Still not sure if level of signal [J] is being other changed except by Gas Feedback system. If it is do not see input for it on schematics for it. I feel like I am missing something.
One thing for Matrix board is the M1 output from GAS FEEDBACK on top of schematic.
This is another case same signal name, but it will require another trace for it to work.
Separate input into AND function on K3 gate generator. Current K3 board has input wired for this.
Note: It is also possible that the M1 interface is not being used and that cell off function took is all that is needed.
The are 2 outputs from K11 Digital Means card the come from the same point one labeled M and M1 same signal. M goes to K8 Analog Voltage Generator and M1 goes to K3 Gate Pulse Frequency Generator.
This keeps everything in sync and you have these traces on Matrix board.
Now there is another M1 in the Gas Feedback Schematic top right of center it goes to Full Cell Pressure Gage. It is this M1 signal I was questioning. Actually I am trying to understand how the the Digital Means and Gas Feedback work together at this point.. My comment right above is miss leading the way it is written.
It should have say the Gas Feedback M1 signal may not be use in later versions. Thing at bothers me about this M1 going to K3 is it is not in sync with rest of system. It may just be a case that there was a planned use for this when schematic was drawn than did not work out.
The reason I built the schematics into boards as I wanted to see what the signal really looked like at each point. I also wanted to know what the controls did to the signals. For example in K3 I found that the gate signal cannot be larger than 75hz as signal flat lines after that.
This is a system limit that is no documented anywhere that I read.
This also means analog signal cannot be higher than 75hz and gate pulse are less that 75hz.
Main reason I have not yet build the Digital Means and Gas Feedback as they are operating controls that I could get around by using the manual controls. Also do not have a cell so gas pressure was not an issue yet though I am being to thing that piece is critical to have a working cell.
Again you could do this with manual controls but Stan's Gas Feedback system should tell you what limits he set. Even picture of gage tells you it low pressure as gage only goes to 15 psi.
One thing we need to keep in mind is we are looking at an evolving system and schematic are a point in time.
Bottom line I do not thing you need another trace on Matrix board. I think we have already added one for Gas Feedback into VIC.
One way to look at both Digital Means and Gas Feedback is they are the automated controls on the system.
Stanley A Meyer Gas Feed Back Card
I started testing board today and have a couple of things I wanted to tell you about. One the led outline on left middle just to left of 10 input is facing the wrong way. Flat side is negative and it should be on the left. This LED comes on when cell is over pressure. (Traces OK just a silk screen change).
The 10/11 input is 0V to start and K about 8.5V both appear to be flat line. Then when cell goes over pressure K goes to 0V and 11/12 goes to around 10V. This means that it can NOT be the GASFB input to the VIC card. (This is one of the things I want to verify as we put a trace on VIC MATRIX to this connection I am pretty sure now that is wrong)
Still looking at  connection the way it is if this is connected the analog output of K8 flat lines. Still checking this.
Starting to get a feel for what the pots on lower side do. But I did get the [K] signal to switch state as I mentioned above. And I was able to move limit setting around. I did put the 4.7k in like the schematic called for on the Limit Pot. Did notice that it gives you a very narrow range to work with.
I am in the process of documenting things as I do testing. But everything in lower half appears to be working.
With exceptions I mentioned above.
I had assumed only one side of power board was active.
Having new traces in place would then always provide a path to rest of boards just by switching active side. (no jumpers needed).
The would also work if both sides are active and your are using both sides of the load to spread load and failure of one regulator would not remove power.
If concern is a failure taking taking out the regulators (my assumption) then if both sides are active and new traces in place then that failure could take out both sides. With switch and fuse in series both still would be protected by fuse.
With current Matrix configuration, with out jumpers or switches on line between terminal screws only, one bottom side would be providing power to Matrix boards on the bottom Matrix. While the top would be active it would not be connected to a load.
A short for example would only damage the bottom load and then top half could be connected with jumpers or switch between terminals.
Both configurations will work, which one you choose is based on design goals. If load balancing is primary concern you add traces. If failure protection is major concern you leave them out. Another case is top half was meant to power some devices hooked to terminal screws then you would also leave them out.
As I am working in lab any of the configurations work for me.
Which configuration you choose depends on what is your primary concern for conditions where board is being used.
The current Matrix board configuration provides Regulated +12v power to power Matrix boards and to power board.
In this case using a new power card the board would only need to provide +10V and +5V using voltage regulators -
Discussion on having 2 side discussed above still applies. So you have +12 into board, and +10 and +5 out.
Stanley's power board will not work in this configuration as the blocking diode on his power board blocks the +12 input.
To get around this we provide power to Stanley's board on Pin's 1 and 9, this needs to be unregulated power (at least at a higher voltage which is also needed by 7812 on Matrix board). This comes from the 15 Amp Fuse on Matrix board in both cases.
(So you do not need a separate alternator source as neither will work with out the higher voltage).
Why the switch? (switch being on matrix to disconnect options not indicated on matrix
The system will function without switch but when using Stanley's power card you will having active +12 power from 2 separate sources as turning off power on Stanley's board would not kill the 12v feed to other boards only the +10 and +5 feeds. Again this is only needed when using Stanley's power card.
If you are using another up stream switch to kill power to the 15 Amp fuse then switch does not matter.
I think leaving out is best answer and using up upstream switch to kill all power, as any switch on other power cards would have the same issue as Stanley's card as they also would not kill the +12 feed. I am doing that now in my test system - I use the switch on power supply and kill everything as it is in reach.
I know first answer is kind of vague. Select they one that best fits your primary goal.
Designer always have this issue when they have conflicting requirements.
At this point this is what I would do.
Leave the traces in top photo off. You can solve this easily later with jumpers on screw terminal pins or even switches on a panel that go between terminal pins. This lets you configure system to meet your primary concern.
Put in traces from 15 Amp fuse to pins 1 and 9 so Stanley's power can be used if desired
