A Powerful..... Compact ...... Cost Effective...And Easy To made Wireless Power Transmission Module.....
Please VOTE FOR ME If you like it.....
So there are a lot of Modules on The web...... But My inspiration is "Wireless Power " By robotkid249
The old one uses a function generator to Generate Square Waves of 147.7 KHz For the module to work .......
But Due to Lack Of resources I had to make one of my my own (Here It Is - Function Generator) but Since Size matters ...... i have to make it more compact....... (After all We are living in Generation Of Nano Technology ).
So....... One night...... I came up with a thought Of using A microcontroller to Generate Square waves and next day i started working on it...... after a struggle of one and a half week...... i came up with this design....... let's Browse...... How to make it.......
The Current Output of Reciever Was 50mA at 3.2V at 5.18V input at transmission dock even the reciever can power an Arduino UNO R3 and most of your AVR's (i've tested it on 2313 with a blink Program and it worked).
PLEASE VOTE AND ADD IT TO YOUR FAVORITES TO SUPPORT.
Step 1: Components You Need......
Let's Browse what We all Need...
1. insulated Copper Wire (called magnet wire in India). much enough to make 150 loops for Transmitter and 35 loops for receiver (Around 45 Metres it was as i remember...)
2 . An AVR (I've Used Attiny2313 and have used Arduino IDE to Program that )
3. An Ordinary led Blink Program.
4. Transistor TIP122.
You can use TIP102 instead of the TIP122 and can increase the input current to 2 A To Get more output current at the reciever
5. Power Source For AVR.
6 Power Source for coil (I've used the same for both avr and the coil ).
7 Diode Bridge or 4 x 1N4007 Diodes (For Reciever).
8 .An LED
Step 2: The Schematic
So The Schematics Is In The Pictures..... BUild as given......
1. You can Add headers instead of led
** Remember To add a 10uF capacitor on the receiver as i forgot to add in schematic
Step 3: Programming the Microcontroller
All YOu need to do is to make a blink Sketch but with a delay of 0.1 millisecond
let me make it for you... since i used arduino IDE i'll be using arduino C ,
// The Program For Wireless electricity Module
int tr = 13 ; // You can add your own IO Pin
and that's all for your program part..... choose your desired io pin for that..... and upload the program to the chip
Step 4: Assembly
1. Solder your desired 5V Power supply to Microcontroller....... i've used a USB cable you can use a charging pin or even a 4V/3.7V Battery to that
2. Wind Up the coil..... clear the coating at ends ...... wind up same tape...... so.... it doesn't unwind itself..... and then solder the ends to wire
3 . Install the transistor as Given in Schematic, base to your MCU's IO pin.... you've set in program..... collector to Coil's one end...... (Another end is to be hooked to power supply) and emmiter to ground(-ve of both MCU and Power Source)
4 . Install Power supply for coil...... in my case i hooked it to the same as that for the MCU (ie coil's free end to MCU's VCC and Emitter to Ground).
The Simplest Of all is making the reciever
MAke a coil of 35 turns...... hookup the recifier bridge and led(or Output terminals) and the capacitor.......
Step 5: Testing the Circuit
test the circuit By supplying some power to it...... if everything goes well..... then glue everything and insulate the wires using heatshrink Tubings.....
Step 6: Beautify Your CAse
Beautify your case...... the project should look good as well as from outward...... in my case...... i've sticked the coil inside the case..... and had applied sticker sheet on the top..... so it looks plain from above..... not like hanging or the bulging out coil...... draw anything so as to make it look cool..... decals your emblems and all those pretty stuff......
Step 7: Done.....
your pretty...... project is ready to be rolled out.....
