If you get Ten new or used Interstate 6v golf cart batteries and make Five 12v batteries. Build as below but add the small bulb (LP1) and 1K pot (R1) in series with R2, which is now a 10 Ohm resistor.

Also on the charging batteries, you can branch out at D2, with diodes to each charging battery. For each diode going to each charging battery you can parallel several identical diodes (5 or 10) for each branch. Just make sure the 5 diodes are going in the same direction (as shown), and tie the ends together (which makes one big diode out of 5 or 10). If you use 5 diodes per brach going to each battery in a five battery setup (1 powering battery and four charging) then you will have 5 x 4 = 20 diodes total at D2.

Or you can just parallel all four charging batteries and parallel 20 diodes in one branch going to the batteries postive wire. The neon bulb (NE-2) is simply one neon bulb in series. One additional update is on the coil (T1). Cut 150 to 350 feet of each wire (same length). You can use two #18 size wire at 150 feet instead. Instead of winding two wires in parallel, twist the two wires like litz wires. For these smaller size wires you can have 6 or more twists per inch. Just don't twist too much or they will break. Then wind it as you would have the other wires. Use the parts listed below and on this site. You can use the transitor BD243C as found in John's patent in place of the one below. There are more updates.

## Following Two Schematics by Bedini

See the Bedini_Monopole [1]  (http://groups.yahoo.com/group/Bedini_Monopole) list for details.

Bedini's School Girl (Simplified) Schematic, Sketched by John Bedini for this project Sept. 27, 2004.

Above Schematic corresponds to the photo and Schematic below.

KEY:

B = Base
C = Collector
E = Emitter
R1 = 680 Ohms resistor
D1 = 1N4001 Diode
D2 = 1N4007 Diode
N1 = Neon Bulb
B1 = Run Battery
B2 = Charge Battery

# Analogous Circuit Photo

Close-up image of an analogous circuit to the Bedini SG. This photo corresponds to the circuit sketch above.

Note
Transistor body is different than the 2N3055 called for in these plans.

• ## T. Cullen's Simplified Schematic

Note: while this schematic is functional, we have learned of John Bedini's recommendation to make the connections as short as possible, especially the diode between the base and the emitter of the transistor.

Another Schematic shows four batteries on the back end being charged, with diodes to isolate them electronically from each other. Neither John Bedini nor Peter Lindemann have commented yet on this circuit variant, posted Dec. 16, 2004.
