| This is to inform all of you that I already tried this project and i am successful. I have submitted it as my final year University project in which I succered 100% marks. Only few amendment I have made to the both Transmitter & the Receiver circuits. In Transmitter I used 1-Ordinary Laser Pointer instead of Laser Tube and 2-Audio Transformer of 8:1000 Ohms instead of 8:2000 Ohms. And at Receiver Circuit 1-Ordinary LDR instead of NPN Photo transistor. And apply totally two different power sources to the Circuits of TX & RX. If Any Body Needs Help Then Leave A Message For Me In This Regard. |

| i am trying to demonstrate this transmission as my 1st semester project. i build-up the transmitter using 555-timer circuit and receiver as u mentioned but its quite not working. I had used l14f1 qt840 photo-transistor; is it appropriate to use it? what you suggest me to do? i try to get the audio transformer of 8-2000 ohms but i couldn't get it on market which one can replace it?

| i am using the same concept to modulate a red laser at 2.5khz and recieve it 100m with a light sensor to count a hit or a miss.The problem is that it works fine in the dark but with sunlight it doesnt..any idea as to WHY???(is my laser getting saturated(decreased intensity) or is it the noise due to the sunlight?) any ideas on how to solve this problem?? can i get an off-the-shelf laser TX/Rx module that is immune to daylight with 100m range?? |

| i need help for my project. i have two analog signals to send (i must use 2 transmitter device and 1 receiver device : according to the project) so i dont know how can i spread at the end of receiver. |

| hello sir,
could you send the brief explanation on this project,because i was prepare one power point presentation on this topic. |
