Introduction: Wireless Electricity Transmission (Simple Things Required to Be Collected From Scrap)

Soldering Challenge

Runner Up in the
Soldering Challenge

Wireless electricity is something new and exciting. While its core principles are fairly easy to understand it can quickly become overwhelming for the average person. I faced a similar problem, I found the whole thing rather overwhelming to understand due to the fact that there were many different things that I felt I needed to understand to be able to make one. So lets get to it! and here's a video of it working:-

Step 1: Things Required

To make this we need :-

1) NPN Transistor. I used the transistor from my old telephone pcb

2) insulated copper wire that I took out of my old cfl bulb

3)Resistor 1 Kilo Ohm. I took it from old telephone circuit board.

4) L.E.D light

5) A 1.5 Volt AA Battery or CMOS battery would work similarly.

Tools required :-

1)cutter

2) Matchsticks or lighter

Step 2: Collecting Things From Scrap

For transistor search in the old pcb if you find it then solder it from the circuit board .For resistor :-

  1. search on internet about its color bands
  2. search in pcb
  3. remove it from the pcb

Step 3: Circuit Schematic

Here is the diagram of the device. Diagram is also present.

Step 4: Making Receiver Coil

First of all take the insulated wire roll that out and with wires,make a coil of 30 turns around a round object.Tie roll on the ends of the wires, to not make it messy.Make sure that the turns must be 30 only.

Step 5: Making Transmitter Coil

With the same round object, start coiling again. This time when you make your 15th turn with the wire, create a tap and leave a wire of 3 inches and then coil another 15 turns. Now you have a coil with two ends and one tap.Tie knots on the ends of the wires, so that it doesn't uncoil by itself.

Step 6: Scraping Ends of Insulated Wires

Melt the insulation from the ends and the tap from both the coils..Use lighter or matchsticks for it.

Step 7: Join L.E.D to Receiver

To make the receiver, just take receiver coil and connect its ends to the leads from the L.E.D.Make sure that the ends of coil are not insulated.

Step 8: Joining

Take the transistor, and place it so that the flat side is facing up and the leads are facing towards you. The lead on the left is the Emitter, the lead in the middle is Base, and the lead in right is the Collector. Take the resistor and connect one of its ends to the base of the transistor. Take the other end of the resistor and connect it one of the ends (not the tap) from transmitter coil. Take the other end from transmitter coil and connect it to the Collector of the transistor. If you want you could connect a small piece of wire to the Emitter of the transistor (It would work as an extension of the Emitter.For more clarity please refer the diagram.

Step 9: Joining Battery

Just take the tap from transmitter coil and connect it to the positive end of the battery. Connect the negative end of the battery to the Emitter of the transistor. Now if you bring receiver coil with the L.E.D close to transmitter, the L.E.D lights up!This seems to be dream!

Step 10: Making Enclosure

Just take a cardboard square and join the transmitter to it arranging it yourself with that switch so it doesn't run out the chemicals from the battery.

Step 11: Done!

Electric and magnetic fields are created by charged particles in matter such as electrons. A stationary charge creates an electrostatic field in the space around it. A steady current of charges (direct current, DC) creates a static magnetic field around it. The above fields contain energy, but cannot carry power because they are static. However time-varying fields can carry power.[16] Accelerating electric charges, such as are found in an alternating current (AC) of electrons in a wire, create time-varying electric and magnetic fields in the space around them.

Suggestions for improvements are more than welcome. Good Luck with your project!!! Please vote if you like!

Thanks!

Just curious, what is the range of the transmission?

Cool! Yes, Tesla Was The Man! Define Madness & Genius? ----A madman uses his genius destructively, A Genius uses his madness Constructively - Nicola Tesla was the latter! born in the wrong time, a gentle sole and abused by the greed of other more influential people of his time! Did someone mention Edison? ;-)

Didn't Nikola Tesla go broke and insane chasing his wireless electricity dream.

If I recall, Tesla's troubles began when Edison entered the picture. It's not a pretty story and frankly, downright tragic. I lost a lot of respect for Thomas Edison.

I agree.
I've lost all respect for Edison after I found out what a shister and thief he was.
Tesla is within the top two of the world's most genius humans that ever lived. In my mind, being equal with Davinchi.

Edison was a well established inventor and much older than Tesla. Tesla worked for Edison.

In 1882, Tesla moved to France, where he began working for the
Continental Edison Company, designing and making improvements to
electrical equipment.[46] In June 1884, he emigrated to New York City in the United States.[47][48][49] He was hired by Thomas Edison to work at his Edison Machine Works on Manhattan's Lower East Side. Tesla's work for Edison began with simple electrical engineering and quickly progressed to solving more difficult problems.[50]

Tesla was offered the task of completely redesigning the Edison Company's direct currentgenerators.
In 1885, he said that he could redesign Edison's inefficient motor and
generators, making an improvement in both service and economy. According
to Tesla, Edison remarked, "There's fifty thousand dollars in it for
you—if you can do it."[51][52]
This has been noted as an odd statement from Edison, whose company was
stingy with pay and who did not have that sort of cash on hand.[53]
After months of work, Tesla fulfilled the task and inquired about
payment. Edison, saying that he was only joking, replied, "Tesla, you
don't understand our American humor."[52][54]
Instead, Edison offered a US$10-a-week raise over Tesla's US$18 per
week salary; Tesla refused the offer and immediately resigned

Yeah I was thinking not all that new. Still like the project though.

> Wireless electricity is something new and exciting.
LOL. Check out Tesla.

wireless electricity is simply radio energy... and it is not new. In fact it is very old. Tesla IS responsible for our AC grid, but there is a reason why we're not powering devices with radio energy. (i.e. I assume you like to idea of not being slow roasted in your sleep by the radar antenna in your living room).
