This set of two circuits from the basis for a very simple light wave transmitter. A LASER beam is modulated and then aimed at a receiver that demodulates the signal and then presents the information (voice, data, etc..). The whole thing is very easy to build and requires no specialized parts execpt for the LASER itself. LASERs are available from MWK Industries. |

| hello sir, could you send the brief explanation on this project,because i was prepare one power point presentation on this topic. | ||
| the circuit its work but if you need some more special aplication so need a more sophisticated circuit . this is a very basic circuit to show how it works the theory . don be ox | ||
| hi i need a help because i have struck in the middle of the project. i have a problem in transmitter circuit & problem is with the circuit before laser part nd i got this circuit from efymag so please help me | ||
| Why not simply wire the audio signal through the batteries of a pen-laser, and pick them up on a small solar panel soldered to RCA jacks? Does the same job for $10...I built one years ago after reflecting a laser off a window, receiving it on a solar panel, and realizing that the sound I picked up was just the modified wavelength of the beam...It was the sound of my family talking inside! | ||
| FIRST:IF YUO WANT TO TRANSTIMT VOICE OR A SIGNAL YUO NEED TO MODULATE..DE LASER BEAM ITS ONLY A CAREER..SEAR FOR AM OR FM ..ITS THE SEAME BUT WITH LIGTH SECOND :I THINK THAT YUO CAN DO THIS WHIT A CHEAP LASER POINTER, MODULATED WITH A 555 ..AND STUFF LIKE THAT 3:FOR ALL OF YUO THAT DONT UNDESTAND ..THAT I REALLY RECOMEND TO LEAR ELECTRONICS..AND REALLY THE FORREST MIMS iii COLECTION BOOKS (ALL STUFF FROM RADIOSHACK)ARE REALLY COOL..A LOT OF IMPRESIVE CIRCUIT AND VERY SIMPLE...WELL LIKE OTHERS OF CORSE 4:I AGREE THAT PLAY WITH LASER TUBE , HIGH POWER LASER ..ITS A LITTLE RISKI..JAAA..SO..LEANR FIRST AND PLAY BEFORE.. BE THE WAY...TRANSMIT DATA WITH LASER HAVE SOME PROBLEMS:THEY NEED TO BE COLIMATED ..YUO KNOW LIKE A LINE AND A TARGET ... SORRY BUT I DONT SEE ANY MODEM IN THE MATERIALL LIST...:U1,U2 ARE VERY COMONE CHIPS AND CHEP TOO, AND AUDIO TRANSFORMER ITS NOT A MODEM.. THE CIRCUIT ITS NICE ..BUT I DONT KNOW THAT ITS REALY WORKS...REALY I DONT KNOW NOTHING!!BYE HUMANS... | ||
| I noticed that the single power supply method is used for U1. Should not pin 3 be connected to a half-rail voltage divider circuit? Does this work as it is? F.M. | ||
| what are the advantages of using lasertorch in voice transmitter & receiver | ||
| I don't know about LASER Tube | ||
| my brother once showed me tht he cud cut paper using a normal LASER we get in t market, as a pointer.. has ne1 else heard of this or wud u kno how to create it... | ||
| has anyone used this laser/receiver/detector in light language say to be connected to a laptop.? Does the audio have light pulse carrier send/receive capability? Would our # pulses of light translate into sound? If the laser is detected is there anyway to send the correct response intelligently. MRUW | ||
