Right off the assembly line
I am a 15 year old student in tenth grade, from India. I have been trying to make a project on Light Fidelity for a science event in my school. I decided to start simple, and transmitted the audio signal from a pocket radio to a mono speaker. This is how I did it.
I connected a stereo jack (3.5mm) to the radio. I connected the ground pin of the jack to the cathode of a small LED. The left channel pin was connected to the anode of the LED. In addition, I connected a 9V battery with a 1k ohm resistor to the anode and cathode of the same LED. This was my transmitter circuit.
In the receiver circuit, I simply connected a solar panel (6V) to the speaker. I powered the speaker through wall socket (230 V AC current). It worked. I was able to transmit audio.
Now, I want to be able to transmit a video, in the same way you did in your TED talk a few years ago. This time, my input is an AV jack from an old DVD player. I connected the ground wire of the AV cable from the DVD player to the cathode of LED and the positive wire to the anode of the LED. In addition, I connected a 9V battery with resistor to the LED. As above, I connected the solar panel (6V) directly to the AV cable of a mini screen which takes AV input. The screen is powered by a wall socket.
This time however, nothing shows up on the screen. I tried using an LED of higher brightness (1 watt). Now, only an icon shows up on the screen which says "AV 1 detected" for a short while and then disappears altogether.
I would be obliged if anyone explained to me how you achieved video transmission through Light Fidelity. I would be very grateful if you sent me a detailed paper regarding this project. Even a circuit diagram would greatly help. Thank you.
