Sterling's Bedini SG Replication Chronology
Chronology of Sterling D. Allan's Replication of John Bedini's Simplified 'School Girl' Motor and Battery Energizer
Reverse chronological sequence. Mountain Time, US
Saturday, Jan. 1
- Exp. 20.1: Like Balancing an Egg on End - Reports a phenomenon in which a quasi-steady balance point is attained between solid state resonance and the first rotation speed. At that point, the meter jumps all over the place.
Friday, Dec. 31
- I revamped my main index page, and created this separate page for chronology.
- Bedini OU Conclusion for Exp. 18 Retracted - Sterling posts YoTango's results and concedes that his (Sterling's) assumptions about Watt usage were flawed, and that an OU conclusion is not supported by Exp. 18.
Tuesday, Dec. 28
- I replaced my ~425-turn coil (which has 20 and 22 AWG wire) with my new 1290-turn coil, with 19 AWG wire.
- Battery Load Test Evokes OU Conclusion for Bedini SG - Though output was less than input,
the amount of energy required to keep the motor wheel in motion during charge bespeaks the tapping of radiant energy. (PESWiki; Dec. 28)
Friday, Dec. 24
- I replaced my 22" diam. wheel that had 16 magnets around the perimiter, with a 16.6" diam. wheel having 24 magnets around the edge.
I've also gone to a smaller wheel diameter and have increased the number of magnets, diminishing the spacing between magnets down to 1.5 magnet widths between magnets.
I've had my coil wound for a few days, but have wanted to first document the effect of adding more magnets, using my previous coil, before introducing the new coil. Those tests are complete, and the new coil has now been glued in place and testing will begin forthwith.
My wheel is a new front bike tire rim of 16.5 inch diameter, minimal wobble (~4mm). The spokes are steel, but the rim is non-magnetic. I've fine tuned the bearings so the wheel turns with minimal resistance. I've arranged the magnets so that they alternate as follows. One directly over a spoke, next one straddling between two spokes (direct middle), repeated around the wheel. I've also wrapped the magnets with fibrous packing tape to prevent magnet fly-off in case the glue gives out (which it does when jarred metal on metal).
Monday, Dec. 21
- Rayovac Maximum Plus Alkaline AA non-Rechargeable batteries do not hold charge - Four non-rechargeable Alkaline AA Batteries by Rayovac took a charge from the Bedini SG but then did not perform under load.
Sunday, Dec. 19
- RPM Fluctuations documented - odd phenomenon noticed and recorded. Graph included.
Saturday, Dec. 18
- Eveready® NiCd Rechargeables endure longer on Bedini SG charge - A baby swing ran 1.43 times longer after the second charge of four NiCd D-size batteries.
Friday, Dec. 17
- Experiment 17 by Sterling Allan: Continous Rotation of Conditioned Batteries - Flirting with over unity -- tapping into some external source of energy. Commenced Dec. 10, 2004, still under way as of Dec. 17.
Tuesday, Dec. 14
- Very unusual thing happened: static phenomenon; short - Sterling's reporting on Dec. 13 observations during Exp. 17.4
Monday, Dec. 13
- Exp. 14.2 by Sterling Allan - Compares Steady State Discharge with Average Voltage Drop During Continuous Rotation of Conditioned Batteries. Dec. 3-10.
Saturday, Dec. 11
- Net Battery Capacity Goes Up after 28 Hours - Capacity is a much more indicative measurement than just battery voltage. Possible proof that radiant energy is coming into the system.
- Brief update of Sterling's recent experimentation - Thumbnail sketch of three reports pending.
Tuesday, Nov. 30
- Continuous Rotation of Conditioned Batteries - Four batteries being charged in Bedini SG circuit, taking turns on input, show voltage drop slight enough to encourage the notion that external (e.g. "radiant" / "aetheric") energy is being tapped.
Sunday, Nov. 28
- Rotating without shut-off - Sterling posts a method he devised for rotating a back-end battery set to the front end, and the front-end to the back-end, without disconnecting the circuit, to minimize equilibration that usually occurs during disconnect.
Wednesday, Nov. 24
- Same Charge Current with Three Different Input Scenarios Shows Uniform Charging Speed - Each schenario delivered 0.040 amps +/- .001 to the receiving battery. One scenario entailed the wheel rotating at nearly twice the speed as another scenario. A third scenario entailed a large variation in the gap between the wheel and the coil. Battery charged a nominally the same rate each time.
Friday, Nov. 19
- Experiment 10.4 Standing Discharge Rates - Batteries longest on the Bedini Circuit discharged significantly more slowly at first, but then after a day discharged to a lower voltage than those batteries that are more recent to the circuit and lower than one that was damaged early on, and dropped rapidly at first.
Wednesday, Nov. 17
- Influence of Gap Between Wheel and Coil - Exp. 11 by SDA shows that the closest distance does not produce optimum RPM. (Nov. 15,16 data)
Sunday, Nov. 14
- Ohms v Amps v RPM and Multiple Stable Rotation Curves - Sterling's Bedini SG data shows several regions in which two stable rotation speeds are obtained at the same resistance in the Bedini SG circuit. Looking for ideal resistance for running the motor-energizer.
Wednesday, Nov. 4
- Zero Change Detected in "Zero Current" Bedini Charged Batteries - Extrapolating to a point where output current goes to zero, with high frequency pulsing of the circuit, the expected results were to see super robust batteries. Instead, the load test showed no change. Perhaps different load types respond differently?
Sunday, Oct. 31
- Charts from SDA Experiment 6 Graphing ohms versus amps. Includes discovery of "zero charge" output point.
Saturday, Oct. 30
- Batteries 2 and 5 load test compared (Bedini SG rep by SDA) - Battery 2 had been all over the Bedini circuit and was fairly well conditioned. Battery 5 started later, and was only "solid state" (no moving parts) charged, including the "no current" charge. Battery 2 held its charge better than Battery 5, possibly because it has spent more time being conditioned in the Bedini circuit; though I expect that the "no current" charge will prove to be more robust all other things held the same.
Oct. 29, 2004
I have been innundated with data, and am sorting through it all trying to make sense of it and think of the best way to present it clearly here for your benefit. Here is what I expect to see; and some of this seems to be supported by what I can preliminarily see in the data.
- Bedini_SG-charged batteries discharge under load slower than factory-new batteries.
- Bedini SG solid state resonance mode (rotor not engaged) charged batteries discharge under load slower than Bedini SG rotor-charged batteries.
- "No-current" charged batteries (report pending on how I discovered this) discharge under load at about half the rate of solid-state-charged batteries.
Yesterday I hooked up Batt 7 (had never seen Bedini circuit before) to "no current" charge mode. Today I added Batt. 5 and Batt. 2 to it in parallel in same mode. (They have been load tested and are now at 6.2 volts resting).

Oct. 25, 2004
- Preparing Exp. 8 in which I will hit each batery with a computerized load tester.
- Exp. 7.1 continuing. Batteries 1 and 5 on the "zero current" set-up increased slightly in charge, but are mainly holding steady, while their control counterparts are dropping slowly.
Oct. 24, 2004
- Discovery of "zero current" domain, and am now running experiment 7.1 to explore it.
- Need to graph and analyze results from Exp. 6 (solid state charging), but cursory glance is promising. Charge was slow, but appears solid, compared to one that quickly recedes after charging. Batt. 1,2 on supercharge (used some solid state input, but mainly with rotor for mroe speed) went up to 7.9 volts, but dropped down to 6.54 after two days, quickly at first, then much more slowly. Batt. 4,5,6 charged from ~6.36 volts to ~6.54 and are holding their charge, dropping just slightly.
Oct. 23, 2004
- Sterling Allan's Experiment 6.x page commenced. Experiment to (1) determine the window where solid state (no wheel rotation, but circuit activation by resonance) can take place; (2) supercharge more batteries, seeking optimal solid state charge profile in process.
- Plotting ohms versus amps in the solid state region, including correspondence to notes on the music scale.
- Looked at a resonance with .09 amps / F# above C and the pitch on the fan on my hard drive. They "sang" to each other, and seemed to increase the charge rate on the output side. Need to plot data to confirm. Switched between computer on/off several times to document the effect.
Oct. 22, 2004
- Experiment 6.x page commenced. Experiment to (1) determine the window where solid state (no wheel rotation, but circuit activation by resonance) can take place; (2) supercharge more batteries, seeking optimal solid state charge profile in process.
- Have commenced an experiment to document the window of ohms that will produce the solid state (no moving parts) charger effect. The window is looking to be very wide. Hope to report on that this evening. Increased ohms = increased pitch (frequency) of the vibration and decreased amp output. Preliminarily, it looks like the amp-ohm relationship will be one-to-one when the ohms are charted on a logarithmic scale.
- Finished supercharging Batt.#1,#2 at 4:34 pm. Spanned around 72 hours. Went from 12.32 volts (two 6V in series) to a final peak of 15.79 volts. Ascent resembled a mountain climber, with peaks and valleys in between, as well as slow and fast ascents. Rough estimate is that there were five major peak/valleys, with probably some 30 minor drops (pause). I also imposed several human errors, accidentally shorting out the battery twice, for example. The highest peak was 16.12 volts. Peter Lindemann says that each of these dropbacks is when the impedance of the battery is decreasing (more charge capacity), and the actual physical chemistry of the batteries is being modified to be able to handle more charge. It is conditioning the battery. I would like to graph this for you, but it is a bid daunting because I accumulated 31 pages of hand-written data, and I don't know of a program presently on my system that will enable me to enter the data and then present various portions as I want. MS Excel is woefully inadequate, unless I just need to know the tricks.
Oct. 19, 2004
- Solid State Resonant Effect Accidentally Discovered - in process of running an experiement on various resistances versus amps and rpm.
- 7:05 am; switched input and output battery sets, commencing experiment 5.3. Solid state effect persists.
- Ran solid state experiment 5.2 through the night in first configuration.
Oct. 18, 2004
Got more parts from radio shack and am up and running again. Experiment 5: (using two 6-V Panasonics in series [12-V] on input and output)swap out various resistor sizes to seek optimal speed per minimal amps out.
- Solid State Resonant Effect Accidentally Discovered - in process of running an experiement on various resistances versus amps and rpm.
Oct. 17, 2004
I went back and looked at the data I pulled in last night, toward the end of a fourth collection set.
With two 6V in series on the input and two on the output, I saw the AVERAGE voltage INCREASE over time during four consecutive runs of about two hours each, though the voltage would drop each time when I switched input to output.
By "average voltage," I mean the voltage of the input battery set plus the voltage of the battery set being charged, divided by two. That amount was increasing over time. Before, with just the 6V, it was decreasing.
I learned some things from Peter about how to time the thing that I will be implementing once I get the components. It looks like I'm not far off the mark now. The two panasonic 6-volts in series seems to be closer to an impedance level that matches this circuit design. Also, I'm operating the batteries above the 20% discharge level. Both of these factors are probably in play.
Next thing. I put the trickle charger on (1:23 am) to keep batteries 1 and 2 up, while super-charging batteries 3,4. I removed the trickle around noon today, letting the front end just run off it's charge within the 20% full charge range. As of 4:00 pm, the combined voltage of the receiving batteries is up to 14.42 V. Battery 4 is pulling in the charge much more readily than 3 is. (I deep discharged [accidentally overslept] 3 down to 2.55 volts on 10/14). As of 4:00 pm, 4 is at 7.85 volts, while 3 is at 5.68 volts. They started out last night at 6.06 and 6.25 respectively.
7:30 pm, fried my transistor again. This time it happened when I hooked what was my back 6V series (12V), fully charged ("supercharged") into the front. I'm now out of materials. May be able to get somethign from local radio shack to be up and running again tomorrow.
Oct. 16, 2004
- Seeing average voltage increasing - four consecutive runs. Too early to conclude, but promising.
- 10:50 PM mdt - Replaced the circuit and am running two 6V in series on the front and back, w/o trickle charger. Kind of playing around until I can get more wire to wrap the coil as recommended and try the tractor 12-Vs again.
- 11.34 AM mdt - I wanted to get an output amps reading, so I was disconnecting the leads to the output batteries, to hook them to the meter, but when I did so, the neon bulb did not flash as it should, and the wheel began decelerating. I fried the transistor again (confirmed by meter readings on the resistances in the transistor). I asked Peter about this, and he had a couple of recommendations for me. First, he said that even though my diodes may be reading okay by the meter, in the previous failures of the circuit, they may have been damaged, and should be replaced. I had only replaced the transistor and neon bulb. Second, he said that I should consider putting a lot more turns of wire on my coil so it has more inductance. He thinks that is why the 12-V tractor batteries are frying my transistors.
- 11:22 AM mdt - I ran a deceleration curve so I could calculate the amount of friction picked up by the wheel at 147 rpm. I used the device to get the wheel up to that speed, then disconnected it and took time readings every five rotations.
- 10:58 AM mdt - Starting last night, I ran the device about 13.75 hours, with two 6V in series on the input, receiving a trickle charge from a NAPA 1-A trickle charger (turns on and off per the level of charge, to keep the batteries tapped), while charging two batteries on the receiving end of the motor using the circuit. They charged to 12.83 volts. The graph plotted on the charging battery, after the initial surge of voltage at the beginning was straight linear at a rate of .06 V/hour. The speed of rotation held constant at 147 rpm, determined visually by counting revolutions over one minute.
Oct. 15, 2004
- Evening: Once again, I rebuilt the transistor circuit, this time soldering all connections, with the help of a neighbor. First I checked to see if it would run on the 6V Panasonic as it did before. It worked just fine. Then I hooked up the 6V Panasonic batteries in series (two on input and two on output) for 12 V on each end, and again the device functioned fine. So apparently, it is the impedance of the tractor 12V batteries that is frying the transistor.
- NOONish: I replaced the transistor and neon bulb. When I reconnected the circuit, the connection sparked heavily, and the wheel starting spinning even before I pushed it. Once I finally had the connection firm, the rotor was no longer accellerating but was decelerating, and the circuit was pulling 6.0 amps. I blew another transistor. It was hot. I was very careful this time to make sure everything was connected right. And in doing so, I am quite sure it was connected correctly last night. I believe the conclusion is that there is something inadequate in this circuit that is not able to handle either 12 volts or the impedence level of the tractor battery I am using. (NAPA BAT-8221)
- AM: When I hooked the 6V back up to the circuit, it was drawing 0.59 amps, and the wheel was not even spinning. Usually it draws nothing unless the wheel is in motion. And then, it only draws 0.18 amps. I'm going to replace the transistor and neon bulb.
Oct. 14, 2004
- P.M. I fried the circuit when hooking up a 12V tractor battery. I must have had a wire hooked up wrong (possibly had output battery terminal connections backward, connecting negative of output to negative of input, rather than positive). I spun the wheel, then connected the positive to the input battery. The wheel did not keep spinning, but acted as though no input power was coming. The input was drawing 2.3 amps. The neon bulb no longer flashes when the output is disconnected. I probably burned up the transistor.
- For what it's worth, I kept the circuit connected a while, after the above situation (still thinking from previous use that no current is drawn unless the wheel is spinning), and the input battery went from 12.61 volts to 12.64 volts; while the output battery (receiving end of the system normally) went from 12.44 volts to 12.45 volts. They are still at the latter voltage as of Monday 10:15 am. The first voltage reading was stable, from the factory.
- 5:00 AM Finally caught up on some sleep last night (went to bed at 10:00) after getting so little for several nights in a row, running these experiments.
Oct. 11, 2004
- 10:57 am MDT ran wheel deceleration test, starting at 109 rpm running from circuit, then disconnecting, and recording the slow-down characteristics, in order to create a rough calculation of the resistance of the spinning wheel.
- Tried two different (same make) Schwinn odometers, but the magnets around the rim drown out the magent of the sensor of the odometer, causing it to read zero. Tried two auto parts stores for some other system
Oct. 10, 2004
- Peter Lindemann's Coaching of Sterling's Replication - Suggestions about the Bedini "School Girl" (simplified) replication and experiment.
- Video/audio (4.5 Mb mpeg) - shows motor running, general layout.
- Have been taking data about every 5 - 10 minutes for first ten hours of operation of this first major experiment.
Oct. 9, 2004
- Panasonic 6V batteries purchased (new) are rated for 7.25 - 7.45 V ("cycle use"); and 6.8 - 6.9V ("standby use"), so they presently are not fully charged. They measure aroung 6.36 volts each. My battery charger will not charge them because it says they are charged (above 6 V). I'm just going to use them as they came, with one on the front end, and one on the back end, and see what happens to the charge over time as I rotate the front and back batteries.
- Couldn't get solder gun to work (novice). Used nuts and screws and wire nuts instead. About 2 hours, including another trip to hardware store.
- WE HAVE ROTATION! Now I need to redo the connections with solder. (May need to get new soldering gun.) Optimum speed is around 60 rpm. Running off a nearly dead little 9-V Royvac Heavy Duty battery (non-rechargeable), with nothing but neon bulb on output. Interesting relationship between rpm, V and amps.
- Data posted here RPM v Amps - data from first experiment run, shows linear relationship: double rpm imposed = double amps drawn
- Hooked up circuit using alligator clips. About an hour (remember, I'm a novice).
Oct. 8, 2004
- Glued transistor to aluminum heat sink, placed a screw in hole to attach a wire to for collector lead, so I don't have to solder directly to the body of the transistor.
- Cleaned out one set of bearings on the wheel (special tools required to get at other set).
- Glued coil to base of stand.
- Glued welding rod into opening of coil. Around 40 lengths fit in the 3/4" diam. opening.
- Wound coil approx. 425 turns using cordless drill and tape hanging off edges of spool to help count (tape hit my hand each turn, making counting much easier). Used full 150 feet of the 20 gauge. Took about two hours.
- Preparing 4 battery set per "Endless Rotation of Two Batteries" protocol. Determined that batteries arrived in a discharged state and that charging two will be required, rather than discharging two (protocol had presumed the batteries would arrive fully charged).
- Cut 3-foot lengths of welding rod into 3" lengths, leaving them just a tad (1/16 - 1/4") longer than 3".
- Magnet wire arrived. Now we can build our circuits. Hope to have it done by this evening.
Oct. 7, 2004
- Marlin P. Jones & Associates (Florida) said they shipped the magnet wire on Oct. 1 but that it will take 6 business days to arrive, putting it on Oct. 11. Arrg.
Oct. 6, 2004
- Still waiting for delivery of magnet wire. Did not come today either.
Oct. 4, 2004
- "I noticed that the spokes of the wheel are magnetic. Hopefully that will not be a deterrent to proper operation. A completely non-magnetic wheel would be the ideal." -- Sterling
- SDA affixed the magnets to the wheel rim using (super-equivalent) glue and (electrical) tape. Offset the magnets to counteract for wobble in wheel alignment.
- SDA (at local machine shot) created an adjustable setting for the bike axle, to raise it up or down, using sheet of steel (hopefully won't effect mag field as it sits near the center of rotation). Also cut a piece of aluminum for heat sink.
- All parts have arrived except for the magnet wire.
Oct. 2, 2004
- I found a non-magnetic wheel and some lumber in the junk yard and made the stand for the motor. It took me about half an hour to find a bike tire rim that was not magnetic. It came from a mountain bike. The rim is a little bent, so I'll have to take some time to straighten it.
- I spent about 45 minutes in the hardware store picking out some of the miscellaneous items I would need to build the frame including non-magnetic screws.
- The frame took me two to three hours to build. My digital camera doesn't work or I'd show you a photo.
