In this Instructables i will show you how to make a unique useful item, That is Wireless Night Light. You can make this for easy! you can use any color of led you want.

Features:

Portable
Fit in pocket
Bright
Can use as joule thief
Use AA battery
Energy saving
And many more!

OK LET'S MAKE IT!!

Step 1: You Need

For case:

Cardboard
Cutter
A Pen
Some circle object (I use a jar lid)
Clear tape

The electronics Parts:

A 2n2222 NPN transistor / any NPN transistor
Thin Copper wire
Led (any colors you want)

Other:

Some small circle object
Lighter

Step 2: Make the Case

Take the jar lid, place it in the cardboard and mark it using the pen. After that, cut the circle using the cutter.

Step 3: Make the Receiver

Take a circle object, and start winding 20 turn of the copper wire and its look like image 2. After that, burn the 2 ends of the copper wire using lighter and solder the ends to the led.

Step 4: Make the Transmitter

Take again the circle object and wind the copper wire (20 turn + 20 turn ). so the output from the coils is 3 output like image 1 and 2
Now solder the circuit like image 3

Step 5: Insert the Circuit to the Case

Take the 2 circle cardboard, insert the transmitter into the cardboard, and reinforced it using the clear tape like image

Step 6: Finish

Test:

Connect the transmitter to the AA / 1,5 volt battery (i use magnet to connect the wire into the battery)
Place the receiver on the middle of the transmitter
and voila the led is turn on
And test it on the dark place
