FOR RESEARCH PURPOSES ONLY- BUILD AT YOUR OWN RISK!
WARNING!
In these plans you will see many different ways in which you can build your own Inverter, If you decide to
build the DC to AC commutator convertor instead of the step up inverter, you will be using 10 - 12 volt dc
car batteries or marine deep cycle batteries in series which will raise the voltage up to 120 vdc which you
must then convert to AC using our simple method of invention. One 12 vdc battery will not hurt you unless
your hands or body is wet and you touch the terminals. But if these batteries are connected in series this will
raise the voltage and the amperage will be very high as well, about 60 to 80 amps, it does not matter if you
are wet or dry if you touch the terminals you can get killed! Some states may have laws against doing this.

What is an inverter?
An inverter steps up a DC incoming voltage from a
12 volt DC battery and converts it to 115 VAC
which can be modified using special techniques to
convert it to house hold sine wave current.
The Hertz output is adjustable, you can easily
adjust it to a common household 60 Hz. Or for
science experiments you can raise the hertz to any
desired amount by simply speeding up the small dc
motor which you will be using along with our
commutator switches that we invented. Most
inverters sold today have an output of 115 volts ac
and the cheap invertors are not sine wave at all. Our
invention uses much less amperage from the battery
than other commercial models. That means your 12
volt battery or battery bank will last longer. Never
let your battery bank go under a 25 discharge,
they will last much longer and save you money!
5000 WATT5000 WATT5000 WATT
Building a large watt inverter is not extremely simple but if you take your time and do it right you can
save thousands of dollars and you will be learning also. Of course for us it is easy, but once you get the
hang of it you can build more for your own use only! If you wish to manufacture them you must first get
our approval! There is another option to building a 5,000 watt inverter, you can simply connect ten 12
volt deep cycle marine batteries in series as shown below. This can be very dangerous so extreme
caution must be taken! This method eliminates the need to step up the 12 vdc to 120 vdc and you get
much more wattage, 10,000 to 15,000 watts. The 120 vdc is then converted to AC by using our simple
commutator invention, which should be included with these plans. Remember to use the proper wire
rating for DC and AC. The wire for the batteries must be very large gauge to handle the wattage, it is
multi strand wire and together make up about a Vi diameter or more. Make sure your wire is as short as
possible when connecting batteries together. I have never tried it but it seems it would be a very good
idea to use a 10 to 20 amp circuit breaker between your #5 and #6 batteries, this is for safety just in case
you get a short some where. You should be able to find large gauge DC battery wire at a automotive
parts store or Solar Supply house or a local multi store that sells batteries. If you try to use to small of
wire it will limit your wattage output. WARNING! Make sure all connections are very tight and then
paint them with rubber brush-on electrical tape by North American Oil Co. Atlanta GA.
(Hardware stores.) Keep out of reach from anyone!

Brushes should be heavy duty, if not, add more wire yourself to the brushes so they will
carry more amperage. More amperage means more wattage output, all wires should be
heavy gauge to match what desired wattage output you want. Container can be any size you
want. Brushes and contacts should be first tested for as long period of time then oil added.
Use a non flammable oil such as baby oil or vegetable oil. If you want 220 volts to run
motors and 220 appliances add another 10 batteries separate banks and converters, that
means you will need two converters and an experience electrical man to help you if you do
not know how to hook up.

Oil Commutator Switch for Alternating bC to AC
Turn an old 12 vdc 5 amp or 40 amp industrial motor into an Oil Filled Commutator
DC to AC switching apparatus.
The brushes and contacts will be emerged in baby oil or vegetable oil to reduce or
eliminate sparks and heat loss. The motor must be taken apart and the rotor wires that
make up the electromagnetic motor can be taken out, you must then add additional ring
contacts. Or simply use the container and build our copper pipe commutators as seen in
these plans.
As the Commutator turns the incoming 120 volt DC is switched back and forth to the
AC Pickup rings, a second set up AC brushes collects the AC.
Incoming amperage from the batteries must be controlled by using fuses and chokes
and the proper wire size. if you want 30 amp output use a wire that will handle 30 amps.
Now seal all holes and assemble and fill the motor stator container with oil. (It maybe a
good idea to use a non-flammable oil such as baby oil or vegetable oil.) or you can
simply drill small holes in the bottom of the motor and place the entire motor in a solid
can filled with oil. the oil will then fill the motor container and surround the brushes and
contacts
Or you can simply construct your own container housing as so: Container can be clear plexi
glass plastic so you can see what's going on inside, and the top and bottom plates are steel
or aluminum laser cut to your own special size. you can still use a shaft and commutator
contacts from an old DC motor. Be careful 120 vdc has more amperage power than your
house that is why it must be stepped down to safe levels. (The Amperage ) Use house
Circuit Breaker Boxes. And Again Always Use Rubber Gloves. Be safe!

No matter what size inverter you use you will still need 10 12 VDC batteries connected in
series to run the 500 watt, 1000 watt, 5,000 watt or 7,000 watt homemade inverter. You can
also get 120 VDC, by using only 5 12 VDC batteries which will give you 60 VDC. You
then double the voltage with a bridge doubler. Also search the net for Solar Panel companies
they can tell you more about how to connect batteries and boxes etc...

This is our 5,000 watt inverter design, this is a
foundation to work from, of course you can build
it to any wattage you desire. For high wattage
such as 5,000 watts, you must use fat wire and
brushes, ( Large gauge wire ) this design can also
be made non-mechanical by using electronic
switching, but we wanted to make it easy for just
about anyone to build. The commutators are very
easy to build, it may look hard but it is not. We
use our own design using copper piping and J-B
weld epoxy, both are available at any hardware
store near you I am sure.
The commutators are simply an on and off switch.
when the commutators hit the front brushes,
the capacitors are charged with 12 volts dc each,
Then as the commutators spin toward the back
they shut off the front 12 vdc charge for the caps
and they then spin around and hit the back brushes,
which connect the capacitors in series and step the
Voltage Up tO 120 vdc. The drawings do not show the lull
ten brushes needed, we did not want to make it iook to
complicated. _^/ —

BUILDING THE
COMMUTATORCOMMUTATOR
OPTION ONE
This is a homemade Commutator designed by Rick Harrison, This DC Commutator is used to turn off
the incoming DC voltage to the HV Voltage or Low Voltage Magnetic Coil. We are going to create a
junction bar that rotates and as it rotates it will slide onto the 2 carbon DC motor brushes and cause a
complete connection causing DC current to flow into the Electromagnetic coil.
We are going to give you 2 options in making a DC motor commutator. Pick which one is easiest for
you.
STEP ONE
Cut a piece of 3/4”
Diameter” x 1 3/8” length
copper pipe that you can
buy at any hardware store.
Use a pipe cutter to cut a
piece 1 3/8” long.
1 3/8”
Next using rough sand
paper, sand the inside of
the copper pipe really
good. And then clean
with laquer thinner.
Surface must be free
from dirt.
STEP TWO
1 3/8”
STEP THREE
Using a Q-Tip, Grease a piece of card board a little larger than the copper pipe
diameter, this is so the epoxy will not stick to the Card board surface and can be
removed when dry. You now need to fill the copper pipe with Epoxy, so slowly
squeeze out enough J-B Epoxy to fill the inside of the copper pipe, follow all
directions on the J-B Instructions, Mix the 2 parts very well and start placing the
epoxy inside of the copper pipe. Let dry 24 hrs, I prefer to wait 40 hrs, but the
instruction do not tell you that. We use J-B Epoxy because it is the best on the
market and can stand up to 600 degrees.
STEP FOUR
Now you must find the exact center of the pipe and
score it with a sharp punch. You will be scoring or
punching a small hole into the top of the epoxy. Now
you are going to need a drill press. Place the copper
pipe up as you see in figure #3, Make sure bottom
surface is very flat, if it is not the hole will be crooked
and the commutator will ride with the shaft crooked
and cause a off balance at high speeds. start off with
the smallest drill bit you have and work your way up
until you have a hole the same size as your shaft rods
outer diameter.
STEP FIVE
Now using a fine point marker, mark your cut marks
on the outside of the copper pipe piece. As shown in
figure #4. Use a fine tooth hacksaw to cut.
Cut a long center cut all the way around the copper
pipe leaving a 3/4” space. Cut all the way through the
copper and just up to the hardened epoxy fill. Do not
to deep into the epoxy fill.
1 1/8”
Fill in the cuts with epoxy, let dry 24 hrs then sand
down until smooth. Now take a 5/16” steel shaft
and place it back into the epoxy hole, now place a
steel 5/16” shaft collar onto the steel rod and epoxy
it to the end of your new commutator,
( remove the plastic end first. )
Figure #4

Figure #3

You will need a qty of two. The first shaft collar is to hold the shaft into place, allow a 1/8” space or more between collar and Part “D”
The 2nd steel shaft collar is to be epoxied ( Glued ) to one end of the finished commutator.

can simply el iminate t he dump
cap(s) and draw st raight f rom
your 10 working caps. ( We have
never tri ed that though.) /
If you wish to make a small watt inverter, simply use smaller
gauge wire and lower rated diodes. The cap dump is optional, we
have tried it on a 100 watt system but have not tried it yet on a
5,000 watt system, we use a dump cap. It is expensive but you
maybe able to simply connect your alternating setup directly to
your work caps. If you do so, you will not need a dump
commutator and brush. This system is very easy to build once you
get the hang of it. Please use extreme caution and keep away
from children and do not forget to always wear rubber gloves.
The motor to turn the shaft and commutators can be a 1 hp 12 dc
free energy or high efficient motor or you can use solar power.
You may want to consider using copper spring brushes as seen on
page 13 they lost longer than carbon brushes. You can then make
5 - 1000 watt inverters and connect them to different breakers in
your house.

100 to 5,000 watt inverter / Type 3
There are many ways in which to build a 500 to 5,000 watt inverter by 60 Hz.
#1. You can buy an ISOLATION TRANSFORMER 115 V input with a 115 V
output. The amperage of the transformer will give you the desired wattage that
you will need. an amperage output voltage of 50 amps should do just fine for a
5,000 watt inverter. you can make your own isolation transformer by simply
taking apart an old wall transformer and rewinding it. ( same amount of winds
for both input and output. ) the size of the wire and how many winds will
determine your wattage. the bigger the diameter of the wire the more wattage,
But if you wind each side with not enough turns you can burn up the wire or it
will get very hot and be less efficient It is best to just buy an ISOLATION
TRANSFORMER. ( Remember an isolation transformer does not step voltage
up or down, if you put 120 volts in you will get 120 volts out.
Now you must take the isolation transformer and apply a 120 volts DC on/off
pulse to the input coil. you should open and shut the + positive side of the 120
vdc at a pulse of 60 times per second. Of course the only way you will know it
is 60 Hz is by using a meter that measures Hz. or you can try running a house
hold appliance that must run on 60 Hz and adjust the pulse speed that way.
#579
So why pulse the input? ( pulsing = on and off )
If you know anything about electronics you will know that when ever you shut
off power to a magnetic coil you will get a reverse polarity! FREE ENERGY
FROM A COLLAPSING MAGNETIC FIELD. and by doing this it will cause
an AC current to flow to the output of the coil. Size of wire and how many
turns you use will determine your output voltage also. If you buy the wrong
transformer and you put 120 VDC into it and your only getting an output
voltage of 108 VAC, then you can add another 12 VDC battery to increase the
input voltage or you can buy and try another ISOLATION TRANSFORMER.
they are not that expensive.
To pulse the input voltage you can use a small DC motor to turn a micro
switch on and off. for our experiments we used a very small low cost, low amp
hobby motor. ( One you would find in toys. ) we then soldered one bead of
solder on one side of it's shaft, But it is best to have two beads. or you can use a
hard metal glue, epoxy etc... to glue two copper or metal BB's to the shaft or
you can use small ball bearings.

This small toy motor can be replaced with any size motor you would like to use.
this motor pulsing method will also be used in the #3 method of our invention.
The wattage and amperage you want your inverter to be the more every
component you see below must be heaver duty to match the rated power you are
wanting to draw from the batteries. Otherwise components will get hot and can
burn up.

As the shaft motor rotates counter clock wise, the beads come around and hit the micro switch turning it off or
on, It's best to buy a micro switch that turns on when pushed. you can also build your own contacts instead of
buying a switch. You simply build one using the contact method that you will see in #3. you can use nuts and
bolt heads as the contacts, this will increase your amperage rating to a high level, of course if you are an
electrical engineer you can clearly see that you can use our methods of stepping up voltage and apply them to
solid state circuitry. These plans are intended for those who are not educated in electronic engineering.

An Isolation Transformer can be used but it is not very efficient yet at this point, As you read on
we will show even better ways of making very powerful inverters or even DC step up capacitor
transformers, which can also be used as a high or low wattage inverter.
Please build your inverter in a safe container, such as plastic or plywood.
WARNING!
Better yet do what we did, we used an old computer box. Try your best to be neat
about what you are doing. take your time, do not rush it.

WARNING!
The following is an example of how to make a simple capacitor inverter, which can also
be used as a DC stepup capacitor type transformer!
Invented by: David Waggoner of Creative Science & Research
HIGH VOLTAGE CAN KILL YOU! Use rubber gloves! Keep away from children.
Our Step Up Capacitor Inverter
USING A 24 VDC INPUT
This type of inverter is unlike any you have ever seen before, Although capacitors are used
widely in commercial inverters all over the world, We designed this system especially for the
back yard researcher in mind, it is simple, low cost compared to buying a $3,000 commercial
inverter. You may already have all the parts you need at home in your shop. this type of
inverter will use 24 volts DC or you can add more capacitors to allow it to run on 12 volts
DC. but for example we will show you the 24 volt DC method only. 24 volts DC is much
more safer than using 120 volts DC. there is much less chance of a spark igniting the
hydrogen gases and less chance of someone getting shocked to death!
If you do not now what a capacitor is then do not build this inverter yet. Go down to your
local Radio Shack and buy a $4 beginners book on electronics called: GETTING STARTED
IN ELECTRONICS, ( Page 32 ) This book will also teach you what an SCR is. Most of
the parts can be purchased at Radio Shack or purchased by mail catalogs: call these 2
company's and ask them to send you a free catalog. HOSFELT Electronics inc. 1-800- 5246464 or ALL ELECTRONICS CORP. 1-800-826-5432 Peerless Electronics 1815 s. 7th St.
Louisville, KY. 40208 502-637-7674
SO HOW DOES IT WORK?
First of all we start with 2 deep cycle marine batteries connected in series to get 24 volts dc.
Now we must take that 24 vdc and step it up to 144 vdc, and we will do that by using our new
method of using capacitors as batteries, put together in series, EXAMPLE: Charging and
using 2 capacitors; ( see page 19 ) Charge #1 capacitor with 24 vdc and charge #2 capacitor
with 24 vdc, Now remove the charge and each capacitor now has a full charge of 24 vdc. (
Each capacitor should be taped to your table for this experiment.) now using one alligator
clip or wire, connect the + to the - as you would 2 batteries and you will now double the
voltage from 24 vdc to 48 vdc. BE CAREFUL DO NOT TOUCH THE ENDS OF THE
CAPACITORS. YOU MUST DISCHARGE ALL CAPACITORS WITH A WIRE BY
SHORTING THEM OUT OR BY CONNECTING A LOAD SUCH AS A 100 WATT
LIGHT BULB.

Electrolytic Capacitor
Please read this it is very important! YOU CAN NOT CHARGE EACH CAPACITOR WITH 24
VDC AND ALSO HAVE THEM CONNECTED IN SERIES ! You must do one or the other never
at the same time! 1st you charge each capacitor, then 2nd you disconnect that
charge, 3rd you then connect each capacitor ( that now has that powerful 24 volt
charge ) and connect them in series. now it would be stupid to connect and disconnect
all of this by hand. So what you must do is use switches! You can use all relay switches
1- 4 pole double throw and 5 - 30 amp auto relay switches, or you can use 1- 4 pole
double throw relay and 5 - SCR's (Silicon-Controlled Rectifiers.) as switches. ( It is very
easy to do!) Using SCR's is much quieter than using loud relays. you can buy low power
SCR's at Radio Shack or you can buy High amperage SCR's by catalog. use 70 amp x
200v SCR's for a 1,000 watt unit, or 275 amp x 600 volt SCR's for a 5,000 watt unit.
FIGURE #1 is the Charging diagram, this is where you will need to use the 4 pole double
throw relay w/1-70 amp SCR on the positive lead, ( Radio Shack type cat. no. 275-214
12 vdc plug in relay. ) This relay is always in the up position, so the capacitors will be
charging as soon as you connect the battery to the relay, then when you apply 12 vdc to
the coil of the 4 PDT relay it will move the contacts down and this will turn off the charge.
All of this will happen very quickly! Because instead of connecting the relay coil to the 12
vdc battery by hand you will be using our MOTOR MICRO SCR SWITCH METHOD The
switching must be fast in order to charge the main capacitor bank, which you can apply
your load to this, such as a 100 watt light bulb etc... DC only at this point. So you see
what we are doing here is eliminating the need to place 10 - 12 vdc deep cycle
batteries in series to get 120 vdc. we are simply using capacitors instead. But remember
no matter what you do you will always need 10 deep cycle batteries for any average size
home. NOTE: You could also build your own relay and use large bolt heads for contacts,
and make your own 60 amp 4 PDT contact relay. But its not advisable, Using SCR's as
switches work much better!

The following page shows the use of SCR’s to connect the charged capacitors in series to step up the
incoming 12 vdc or 24 vdc current.
Please notice that you can use 4 PDT relays to do the same thing which we have fully tested and found
the relays do great! We have not fully tested the SCR’s yet, but we have done some bench test’s and the
SCR’s look like they will work just fine. If they do not you may know of a better way, please let us
know because we do not have the time right now to test and develop the use of SCR’s, We are working
on more important projects.
Thank you

DC to AC Alternator Inverter
#579
For low wattage applications try this below.. For High wattage use the oil drum brush
and commutator method.
So you have built everything up to this point and you have even lit 100 watt light
bulbs with your new 120 VDC STEP UP CAPACITOR TRANSFORMER. Well it's great for
lighting bulbs and running electric heaters, but now you want to run much more, such
as TV's, VCRs etc... that use AC. ( NOTE: you can take the AC coil transformers out of
each appliance and step down the DC voltage to the required voltage and amps
and run on 120 VDC. )
So what we must now do is take that 120 VDC and turn it into 120 volts AC. Which is
very simple to do. You can do this electronically or you can do it mechanically by
using a store bought 2PDT relay or by building your own relay. We suggest you build
your own relay, see bottom drawings. NOTE: If you are not getting 120 VAC output
but the voltage is much less, then you must increase the 120 VDC output to a higher
voltage until your alternator method is outputting 120 VAC.

Type III CAPACITOR INVERTER
OPTIONAL: Here is another way that you can make a high voltage inverter. Can be done
mechanically or by using SCR’s or Transistor.
To start; Instead of connecting and disconnecting capacitors in series as you may
have seen in our type II Capacitor Inverter, In this new method you simply keep all
caps connected in series as shown in figure #1. Fig. #1 is to help you get an
understanding of how it works. The positive and the negative brushes slide over the
contacts, moving together, creating a 24 VDC charge in each capacitor. For this
simple experiment you will need to connect 6 - 50 Volt x 2200 or 25,000 uf
capacitors together in series. ( solder all connections.)
Now tape down the caps flat onto a table top, Now cut 12 pieces of thick or thin (
thick is best! ) copper or aluminum to 1 1/2" x 3/4" squares and tape them down
as shown in figure #1. Now solder your wire to the contacts and the caps as shown.
Now using rubber gloves place the positive ( 16 gauge wire automotive type ) A
Brush onto the first + contact and the negative B brush on the negative contact
Now slide wires down the rows at the same time and at the same speed to charge
each capacitor at 24 VDC. Slide and charge all the way to #6 cap. So you have now
charged all caps and your DC volt meter should now read 144 VDC. ( Be careful
not to touch, it can KILL! Use rubber gloves. )
Now at this point no load is connected. Always connect load or a 120 VDC cap
bank x 25,000 uf AFTER YOU HAVE CHARGED CAPS, To avoid large sparks
that can burn up your contacts. So again after you charge 144 VDC cap bank you
then use a magnetic reed switch to turn on load.

switch rated at 5 to 10 amps. Now if you will picture the contacts on a round stationary
piece of plywood board and a rotor arm that turns with the brushes on it. to make contact
with the cap contacts.

Now as #7 rotor arm moves counter clockwise, it moves the contact brushes over 1 & 2 and so on. this all happens at a
high rpm. ( You can try with lower Rpms to meet your needs.) The #4 brush is actually a set of brushes with 2 round
commutators, the same commutators you would see in a AC motor, ( Not a DC motor!) the 24 VDC from the batteries
travels through the #4 set of + and - brushes and travels through the 2 separate round commutator contacts, up through
the 2 wires, through the brushes and onto the stationary contacts. Then to the capacitors charging them at 24 VDC each
= 144 VDC. The commutator can be simple, using a 2 washer's a plastic spacer to protect from shaft, and some epoxy
glue. or place a flat type onto the moving rotor arm.

Our 5,000 WATT INVERTER
A SIMPLE WAY TO ALTERNATE A DC CURRENT
Well you know how to build the 120 VDC battery bank by now. so now lets go on to
understanding and building a way to alternate that 120 VDC to AC.
First I will show you a simple low wattage way to alternate the DC. By using a radio
Shack 2 pole double throw 12 vdc relay. The relay is rated at 5 amps so relay contacts
will not burn out unless you go over 5 amps. which makes this a good 100 watt
inverter. See figure one. the top two input connections you simply connect to the 120
vdc battery bank. use a 5 amp 120 volt diode for the positive side of battery. use a 5 or
10 amp fuse. Use the proper wire size so your wire will not burn up when load is
applied. Now connect another of the same to the 2nd output but put the + side to the
right and the - side to the left. ( Be sure to use another 5 amp diode and fuse. now
when a 12 vdc on and off pulse ( 60 Hz ) is applied to the coil of the relay. this causes
the common arm to move up and down, which in turn is alternating the DC current to
an AC square wave. You can build this large enough to handle as much wattage as
you desire, By building your own large scale homemade 2 pole double throw relay
switch. Contacts should be made very large and changeable. They can be made with
large bolt head rounded off. this same method can be done with a small low amp relay
and by using high amp transformers or SCR's. you will never need to change contacts.
The transformer or SCRs take the beating. They will get hot so use a 12 vdc fan to cool
them. make sure they are connected to a aluminum heat sink.

square wave. a square wave can run
many things such as AC motors and
such. try it. or if you want a modified
sine wave which is very close to what
you get from the electric company,
then you will need to run the 120 VAC
through a 3-10 amp transformer 1:1
or you can use transformers to multiply
the wattage.

12 VDC BATTERY
This is an easy way to pulse the relay to 60 Hz, ( If you do not know how to make a 60 Hz pulse electronic
generator. ) Please note that the 2pdt relay can be replaced by using 200 amp x 30 to 70 amp Transistors or
SCR's. You use them in the same way as switches. and then use a small low amp 2pdt relay to switch them
on and off. This way the SCRs or the power Transistors take all the amperage punch!
and you wont have to worry about your contacts burning out.

The DPDT relay is being used to alternate the DC current. When contacts are in the up
position +& - position current runs through the 120 vac out put wire, and when the relay is
turned on by 12 vdc 15 ma, the polarity reverses in the wire to - & + , this all happens very fast
and creates ALTERNATING CURRENT TO THE OUTPUT! again as the small DC pulse motor is running
it switches on and off a reed switch causing the relay contact arm to move to upper contacts
and then to the lower contacts.
Now getting back to the relay, It is best to build your own DPDT 275 amp relay. You can make
the contacts changeable. The contacts can be made of bolt heads. For best results sand and
round off top of bolt heads. You must find very large bolts and nuts to take that much
amperage. Once you have it built you can have it working vertical dipped in a oil bath. Do not
dip electromagnet coil into oil, it will short out! Just the contacts.

#3 Method
By now you may have figured out how to build the #3 inverter method, This is by far the most
simplest and easiest way to build an inverter, BUT IS ALSO THE MOST DANGEROUS WAY! again be very
careful high voltage can kill!
By using the 120 VDC battery bank on page 2 , and using the homemade DPDT relay on page
14, You will be able to build the most powerful inverter of all, If you use your brain you will soon
learn you can get much more than 5,000 watts from this method of invention.
If you have no load there will be no spark on the contacts, When a load is applied a spark will
appear and a break down of the bolt head contacts will begin, the greater the load the faster the
contacts will wear. contacts can last a long time. But one should employ a safety net just in case
the contact stick together, this will cause 120 VDC to try and run your AC appliances, although I do
not believe at all that it will hurt them, But you will get a humming noise coming from there AC
transformer or AC motors from the AC appliance, or you may not get a humming noise at all, the
AC appliance will simply stop working but all light bulbs in your house will continue to work since they
can be run on AC or DC current.

You can encase this in a simple plywood box or get as fancy as you want. You can
purchase plastic boxes from the catalogs I told you about.. be sure to put a 120 v
light on front panel with a volt meter, and please do not try and run this without its own
separate fuse box. you can use 120 VAC fuse boxes that you can buy at any
hardware store. PLEASE BE NEAT AND CAREFUL.

#579 Update 5,000 watt inverter
Sorry for the inconvenience, But we left something out Of our #579 plans and have not had
the time to redo them yet.
This update is for the possible 5,000 watt SCR inverter type.
After you have study these plans a bit, you will understand what I am going to tell you. On the
Charging Circuit Diagram. Up on the top left hand of the page is a SCR, This is not hooked
up right. The positive + side of the battery is connected to the A of the SCR not the C. and
the output is connected to the C not the A of the SCR. ( Just Reverse that )
Now every SCR once it is switched on will stay on until the power going through it is turned
of. But we found out you can turn off a SCR without harming it, by shorting out C & A.
Therefor you will need an on/ off reed switch for every SCR, ( Which we failed to show in
the plans.) Also the delay switch part # 275-214, is no longer needed. It will be replaced by a
special homemade Disk switch device. ( It is the only way to do it. they did not make relays
to do what we need to do. ) The disk turns and is powered by a low amp DC motor. The disk
has a total of 8 door reed switches rated at 2-30 amps. 4 of the reed switches is to turn on and
off the Charging SCR on page 10 and the SCR's on page 12. The other 4 reed switches are to
turn the 4 SCR's on and off on page 14-A, ( To alternate the current. ) Now looking at page
12, you will need 5- SPST reed relay switches for each SCR. ( rated at not under 1 amp. )
They will be turned on and off using the + side of battery # 4 reed door switch to turn off each
SCR at the same time.
The reason we use SCR's in the first place is because they can transfer a very large amount of
power and take very well. ( They take a licken and keep on ticken! ) Transistors or mosfets
could be used to replace the SCR's and would be much easier to work with eliminating the
need for a On/Off homemade disk. you could then use relays. and you would not need 5-SCR
shut off relays. But you would have a much lower watt inverter. We are still working out
some small bugs. If any of you out there have any good ideas please write me.
The Wheel/disk turns as does the strong permanent magnet, The reed switches do not. Turn
wheel using a low power DC high eff. Or Free Energy motor connected to a speed control.
