Bedini School Girl Schematic
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.

Analogous Circuit Photo
Close-up image of an analogous circuit to the Bedini SG. This photo corresponds to the circuit sketch above.
- Transistor body is different than the 2N3055 called for in these plans.

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.
