    INTRODUCTION
    This document is to help group members replicate the Bedini Pulse Charging Systems. The replications begin with
    the Simplified School Girl (SSG) energizer. It is part of the group introduction to the study of Radiant Charging
    Systems or the exploitation of an unproven source of energy called vacuum energy. It is by no mean an exhaustive
    source. Nothing in this document is written in stone. Users are encouraged to innovate, study, and ask questions as
    they see fit. Nothing is guaranteed as to the outcome of a replication. Users are left to draw their own conclusion
    through experiments and further research. It is particularly important that the study results are shared with the rest of
    the group.
Key words: Energizer, Rotor, Stator, Coil, Transistor, Diode, Tuning, Charge Capacity, Discharge Capacity

    MATERIAL LIST
    The following is the list of materials required to replicate the Bedini School Girl energizer. Parts are listed
    alphabetically. It is important to buy extra replacement components in the event of failures.
ALLIGATOR CLIPS
    Purpose
           To connect batteries to circuit
    Specifications
           Wires need to be larger than 20 AWG. Connectors need to be rated for at least 5 Amps.
    Tolerance
           Wide range, with the above minimums in mind, especially the wire and clip ratings.
    Quantity
           At least two per battery
    Sourcing
           Google for “alligator clips” providers
    Estimated price
           Less than $7.00 for set of five
 
    BATTERIES, RECHARGEABLE
    Purpose
            Providint input energy, and receiving output energy from the system. Note that the same battery can’t be
            used simultaneously as both input and output in this configuration; closed loop will not work.
    Specifications
            6 to 24 volt batteries / 12-volt lead acid batteries recommended.
    Quantity
            At least two: one for input, one for output. More recommended for experimental options (1) Control . An
            identical battery to the input battery should be obtained for a control -- to test the discharge parameters of a
            battery independent of the circuit under the same discharge parameters being put to the input battery for
            characterization. (2) Additional batteries of the same voltage and impedance can be added to the output in
            parallel (e.g. to graphically demonstrate more output than input). This is the widest and most crucial variable
            in the system. Plan ahead the experiment you want to run before purchasing.
    Tolerance
            The voltage of the batteries is not crucial, and can be somewhere in the range of 6 to 24 volts for the SSG
            energizer. However, the input and output batteries need to be matched in their voltage and impedance 
            (size). There can be more than one battery on the receiving end, connected in parallel, of a matched voltage
            and impedance (size) of the input battery. For your first replication of this, you will want to use new batteries
            so that bad batteries will not be possible reasons for malfunction of the circuit. Not all rechargeables are
            suitable for receiving charge from this set-up. Lead acid recommended.
    Sourcing
            Google the word “battery” for the best source possible
    Estimated Cost
            $5 (or even free if you rummage) to $75 USD each, depending on make/source/size.
    Battery Care
            It will be important for you to know your batteries' optimal operating parameters form their manufacturer or
            other competent rating service so that you do not damage them by charging or discharging too fast or
            too high/low. As long as you are using the Bedini School Girl circuit to charge your batteries , you will not
            need to worry about speed or level of charging. But if you use another apparatus to charge your battery, you
            will need to know your batteries' charging parameters. If your input and output batteries are matched in
            voltage rating and impedance (size) the circuit inherently balances the charging rate to a level that is not only
            safe but even beneficial to the receiving battery. Overcharge is not nearly the concern with the Bedini School
            Girl circuit as it is with other chargers. Batteries actually perform better under frequent use with the Bedini
            School Girl circuit, than if you let a few days pass between uses.
    Performance
            Obtain the battery data sheets from the manufacturer or on the internet. The following curves are of
            importance: Voltage, Current, Charge capacity, discharge Capacity profiles.
    Property
            Non-magnetic
    Purpose
            To serve as Rotor
    Specifications
 
           24-inch diameter would be fine. Bearings should be in good shape. Rotation should be fairly straight. Make
           sure the rim is non-magnetic. 
    Tolerance
           ±10 inches in the diameter (not crucial at all). The rotor doesn't have to be bicycle wheel. Any non-magnetic
           rotating wheel of similar size and weight should work. These plans are for a 24-inch rim. If you go smaller or
           larger than 24 inches, you will need to adjust the number of magnets accordingly so that the spacing is
           approximately the same. Also, if a rotating axis is desired to convey the torque of the wheel, an alternative
           bearing configuration is required.
    Source & Price
           Free (should be able to rummage one from junk, yard sale, thrift store, bike repair shop, etc.) Take a magnet
           of some kind with you to make sure the rim is non-magnetic.
    Variants
           Other rotor devices used successfully: - CD ROM drive mechanism, - target board; - Child's bike wheel
           (plastic). Use your imagination.
    Bearings
           Bearings for bicycle wheels are terrible, even new ones. Recommend www.VXB.com, remove grease (use a
           citrus degreaser), and add lubricant (or 5W20 fully synthetic motor oil).
COIL SPOOL
    Purpose
           Form for supporting the coil windings.
    Specifications
           Plastic, 3 inches inner diameter by 3 inches long, with 3/4 inch center opening
    Quantity
           One
    Tolerance
           Opening needs to be +/- 20%. Length of spool can be +/- 40%. Material needs to be non-metallic, non-
           magnetic, and adequately sturdy.

DIODE
    Purpose
           Protect the transistor base-emitter junction.
    Specifications
           Recommended: 1N4001; 1 A, 50 V
           (Some models have used the 1N914)
    Parameters
           50-300 volt range; low power, fast silicon diode
    Sourcing
 
    Purpose
           Assure one-way flow of energy from circuit to receiving battery.
    Specifications
           1N4007 (1000 Volt; 1 Amp) [A sister component to resistor 1N4001]
    Tolerances
           High volt rating very important; a lower Amp rating may work.
    Quantity
           One
    Sourcing
           Google for “Diode” providers
    Estimated cost
           Less than $0.50 each
HEAT SINK
    Estimated Price
           Free, or nominal
    Purpose
            To provide a low reluctance path that increases the magnetic flux through the coil.
    Specifications
            Low reluctance, high permeability magnetic material: Welding rod; 0.042" inch diameter copper coated steel
            rod, 3 feet long. (Will be cut to length of the coil spool)
    Quantity
            Get 3-5 lbs. (around 10 rods of 3 feet each).
    Tolerances
            Rough cut okay. Diameter is not crucial. It could be smaller by 50% or larger by 100%.
    Sourcing
            Available at your local welding supply store (such as Oxyarc) or hardware store (such as True Value or Ace)
            Try also an auto parts store. Look up industrial suppler or welding suppler in yellow pages of phone
            book. Phone them; ask for open box item at school project prices.
    Estimated Price
            $0.60 per rod
    Consideration
            The thicker the rod, the harder it is to cut. You're going to be cutting a lot to fill the spool hole.
    Purpose
            The purpose of the 20 AWG is to power the motor and generate high voltage pulses for the secondary
            battery. It is wound parallel with the 23 AWG magnet wire.
    Specifications
            The 20 AWG wire should be insulated.
    Tolerance
            20 AWG or larger gauge wire is recommended.
    Quantity
            450 to 900 turns correspond to about 175 to 350 feet of wire without discontinuity.

    Purpose
            The 23 AWG magnet wire provides the energy needed for switching the transistor ON and OFF. It is wound
            parallel with the 20 AWG magnet wire.
    Specifications
            The 23 AWG is recommended to be copper ennamel coated.
    Tolerance
            The 23 AWG wire can be of the same or smaller gauge than the power winding.
    Quantity
            450 to 900 turns correspond to about 175 to 350 feet of undiscontinuous wire.
    Sourcing
            See above.
MAGNETS
    Purpose
            Affixed to wheel to both (1) transduce motor action to the wheel (2) induce an emf into the coil terminals.
    Specifications
            Ceramic 5; dimensions: 1" x 2" x 3/8"
    Quantity
            Start with 16 singles for a 24-inch wheel, later additional magnets can be stacked to the wheel. Get some
            extra in case of breakage. You also might consider one or two for a control, to measure Gauss before and
            after experimental runs.
    Tolerance
            Must be ceramic (strontium ferrite). Number of magnets is not essential, though an even number and even
            spacing will be necessary if you wish to try and add more coils later.

NEON LAMPS
    Purpose
          The lamp provides a path for the output energy in case the receiving battery is disconnected while the motor
          is running. This prevents burn-out of the transistor. The light should not go ON unless the output battery is
          disconnected.

    RADIO SHACK
    1-800-THE-SHACK (1-800-843-7422)
 
    ASSEMBLY
    BUILDING THE FRAME
           •    Stand needs to have front-back and left-right stability.
           •    Rotor needs to be made of non-magnetic material.
           •    Rotor bearings should be low friction and non-magnetic for small diameter rotor.
           •    Plan for ~1/8 inch gap or less between the coil spool and the wheel with magnets glued and taped.
           •    Frame material should be non-magnetic, but some metal can be present.
           •    The smaller the air gap between the magnets and coil the higher is the motor’s performance.
    Tips
           Counting visually is nerve-wracking and prone to error. Use an audible trigger in winding (e.g. a clacker on
           the spool). Alternatively, you might affix tape to both ends of spool, protruding outward around 1/2 inch.
           This will hit your hand as the spool turns, helping you to count turns.
 
    FILLING CORE
         Be sure to have the side that will be facing the magnets flush with the top of the spool so you can spin
       •
         your magnets close to the spool without hitting a rod in the core.
         You might drill a 1" inch hole in your base around ½"deep for the other side of the core to protrude into,
       •
         Tap the last few rods in with some light object until you can't fit any more.
       •
         John keeps the wires in his circuit as short as possible, going nearly to the quick when fastening his
       •
         diodes to the transistor. The circuit will work with the wires being longer, but he says it works better
         when they are short.
         Also, be sure to use a heavy gauge wire when connecting your batteries in parallel or series.
       •
 
     CAUTIONS
              •  CAUTIONS - Dangers associated with this project are mainly with the batteries, but also with wheel
                 rotation and soldering. Be sure you understand the risks and that you take necessary precautions.
              •  While this design can deliver some good shocks, they are not of a dangerous level.
              •  If the neon bulb is not in place, the transistor is likely to burn out if the device is run without a receptacle
                 for the radiant energy (e.g. a receiving battery). The neon bulb absorbs the excess output energy and
                 serves similar to a shock absorber or fuse (though nothing is "tripped" and has to be reset).
    OPERATING PROCEDURES
    Objectives
    PERFORMANCE EVALUATION
    Once the energizer is configured for optimum operation, place a fully charge battery on the input and an equal size
    fully discharge battery on the output. Let the machine run until the input battery reaches the manufacturer specified
    minimum discharge voltage. Measure the output battery capacity by fully discharging it (to minimum voltage) into a
    known load. Compare the output battery capacity to that of the input battery.
              •  In functional application, you should not draw power from the same battery that is presently being
                  charged. You should have one bank of batteries under charge, and another for discharge, and then switch
                  between them.
              •  See Battery Characteristics 
 
    Once your system is confirmed running, you will want to beef up your connections to optimize the effect. Use a
    heavy guage wire and terminal connectors with crimping.
    The above photo shows a set-up for rotation of batteries from the back end to the front, allowing for single battery
    charging (fresh from the front) while that battery comes up the same voltage as the bank of batteries, so they can
    then be connected in parallel.
Adjusting Resistance
     Note that the arrangement includes a switch to enable meter readings without extended disconnection of the circuit.
     Depending on how responsive the meter is, the circuit is interrupted for maybe one or two seconds using this
     method.
 
    The 25 Ohm resistors give a fine-tuning capability. The bread board enables hard resistor plug-in to the appropriate
    range desired. The 5k Ohm potentiometer enables a wide berth of tuning.
     Note: the 5k ohm potentiometer tends to be unstable in how it holds the resistance. If you wish to lock into a
     particular resistance, you should consider hard wiring the resistors into the bread board and bypassing the 5K
     potentiometer.
Peter and John recommend that we set up our 1 to 4 battery arrangement according to the followings:
     Purpose
            To isolate each of the batteries in the back-end charging bank
     Method
            In addition to the 1N4007 diode coming from the circuit to the batteries positive terminal, branch off to each
            battery with a 1N4007 diode so that they see the circuit independently
     Note
            Harlan tried omitting the diode coming from the circuit, just using one going to each battery, and that did not
            work.
     Ramifications
            •     The worst battery in the set does not become the weak link in the chain.
            •     No need to stop the circuit when rotating batteries
            •     No need to have the bank standing idle discharging while the battery from the input comes up to charge
            •     When the input battery discharges, the battery with the highest charge from the bank (not necessarily the
                  one that has been there the longest), can be brought to the front end to run the circuit
     NB. There is another trick that John will disclose to us in due time.

    CONCLUSION
    A successful replication of the basic SSG is only the beginning of the learning process. The next step is to upgrade
    to more advanced setups involving multi-strand coils, and multiple stators. Applying this technology to other fields
    such as fuel cells is also a possibility.
