hey there! this instructable is about how to make a circuit that can transfer power without wires.

THIS CAN BE USED IN HALLOWEEN PROPS.

Step 1: Materials You Need-

electronic components needed -
transistor 2n2222
26 gauge copper wire
9v battery
100 ohm resistor
9v battery cap
and wires.


tools and equipment needed -
soldering iron
soldering wire
nipper
wet sponge
multimeter
flux
etc


extra equipment needed -
solder fume extractor
a cylendrical object to make the coils (i have used a deo can)

Step 2: Circuit Diagram-

THIS IS THE CIRCUIT DIAGRAM

Step 3: Constructing the Secondary Coil and the Led.

Take your deo-can or any cylindrical object and WIND 10 TURNS OF COPPER WIRE on it LEAVING 3 INCHES FROM STARTING.

TO MAKE THE SECONDARY COIL WHICH WILL POWER THE LED.

Step 4: Now Constructing the Primary Coil.

TO MAKE THE PRIMARY COIL -

● WIND 10 TURNS OF WIRE ON THE CYLENDRICAL OBJECT.
●THEN MAKE A TWIST LOOP (IN THE IMAGE)
●AGAIN WIND 10 TURNS OF WIRE OVER THE WINDING.


YOU MUST BE LEFT WITH 3 WIRES.

Step 5: Wiring the Transistor to the Coil

wiring the transistor-(2N2222)

●TAKE YOUR '3-WIRED' COIL AND SOLDER THE LEFT-MOST WIRE TO THE 'COLLECTOR' PIN OF THE TRANSISTOR.

●NOW, SOLDER THE 'EMMITER' PIN OF THE TRANSISTOR TO THE NEGATIVE TERMIMAL OF THE BATTERY CAP.

● SOLDER THE 1k ohm RESISTOR TO THE POSSITIVE TERMINAL OF THE BATTERY.

●SOLDER THE OTHER PIN OF THE 1k ohm RESISTOR TO THE WIRE OF 'TWIST LOOP'.

●SOLDER THE 'BASE' PIN OF THE TRANSISTOR TO THE RIGHT-MOST PIN OF THE COIL.

Step 6: FINAL TOUCHES

now once everything is done hot glue whole circuit to male it WATER-PROOF.

Power it, amd make sure you DON'T EXEED 9 VOLTS.

THIS WILL WORK THROUGH A DISTANCE OF 6 CMS.


THANKS FOR WATCHING, PLEASE LIKE IT.



HAVE A NICE DAY! :-)
