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. |

| 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 | ||
| show me the pcb of laser transmitter? | ||
| what is th 2 modem chips??????????? | ||
| Can someone please tell me how do a laser torch - based voice transmitter and receiver works ? | ||
| What is it with all these students that don't know shit about electronics. If you can't figure out how to transmit data with this schematic so nicely laid out for you then maybe you shouldn't be playing with lasers. | ||
| thank you for simple diagram...i want to use this to trnsmit data to my com.........how it work? and what are 2 modem chips thnks again | ||
| Replace the laser they show with a laser pointer.
Oh, and if you simply hook it up to a headphone jack you eliminate the need for a speaker as well,as a pair of headphones will act the same.
As shown, this mother is costing about $400-$500
scitoys.com has a better explaination (Editor's notes: $400-$500?) |
