Schematic for John Bedini's "School Girl Radiant Energy Circuit and Motor"


Updated Schematic

Simplified School Girl Circuit Updated Above schematic instructions are not totally accurate about tweeking with the bulb but useful. Do not worry about paralleling the diodes, just make D2 3W 1000V 1N5408. You can charge the batteries in parallel or otherwise. Try and get 10 new or used Interstate 6v golf cart batteries. Build as below but add the small bulb (LP1) and 1K pot (R1) in series with the resistor (R2 which is now a 100 Ohm resistor or you can use 10 Ohm). D1 can be 1N914. The neon bulb (NE-2) is simply one neon bulb. 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. See the Bedini_Monopole3 [1] list for details.

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.

  • 1 Solder junction (insulated base [same for 2,3,4]) joining (a) wire coming from (+) battery "in" and (b) #20 magnetic wire to coil and then to collector
  • 2 Solder junction joining (a) wire coming from (-) battery "in" and (b) emitter and (c) Diode 1N4001 and (e) #23 magnetic wire going to coil then resistor then base.
  • 3 Resistor 680 Ohms, between (a) Base/Diode1N4001 and (b) #23 magnet wire going to coil then emitter.
  • 4 Solder junction joining (a) diode {19} (1N4007) and (b) wire to battery receiving charge.
  • 5 Insulated wire coming from (+) battery "in"
  • 6 #20 magnetic wire from (+) battery "in" to coil and then to collector
  • 7 Insulated wire coming from (-) battery "in"
  • 8 #23 magnet wire coming from emitter to coil to resistor.
  • 9 Wire connecting 1N4001 diode to junction {2}
  • 10 Transistor emitter, connected to junction {2}
  • 12 Wire connecting 1N4001 diode to (a) base and (b) resistor {3}.
  • 13 Transistor base: connected to resistor and diode 1N4001
  • 14 Resistor connected to #23 magnet wire going to coil then to emitter.
  • 15 from resistor to #23 magnet wire to coil to emitter
  • 16 #20 magnet wire (per Bedini SG specs) from transistor's "collector" lead
  • 17 connection of transistor's "collector" lead to wire to Diode 19 and to #20 magnet wire 16 to coil to input battery's positive lead
  • 18 wire from transistor's "collector" lead to Diode 19
  • 19 1N4007 Diode 1000V
  • 20 Insulated wire to positive terminal of battery receiving charge
  • 21 Transistor (Different one in this photo than is called in these plans)
  • 22 Aluminum plate heat sink
  • 23 Neon bulb, between collector and emitter. (not shown in picture, nor schematic, but that is where it goes, and that is where it is situated on the school girl simplified demonstrated in Bedini's shop).

T. Cullen's Simplified Schematic

while this schematic is functional, we have since 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.
