would it work to use a garage door openers obstruction sensor set for the sending and recieving signals and what would i have to do if it will work? and i love your site its amazing and plan to use the laser communicator for science fair | ||

The sensor is probably a missing pulse detector. These work by sending pulses of a certain length, such as 1 millisecond, at a certain rate, such as every 5 milliseconds. The receiver has a timer that goes off in 6 milliseconds, unless it is reset by the receipt of a pulse from the transmitter. The range is probably about 40 feet. The laser communicator is probably much simpler to build and modify, cheaper, and has a range of hundreds of feet without optical aids, or miles if telescopes are used. | ||

ok thank you. your science toys really interest me. what kind of education do you have to be so knowledgable in this type of stuff? | ||

I started out as a biochemist, but these days I write compilers and operating systems for computers. | ||

would it work if i used a transformer set to 8ohms to 1300 ohms ?? | ||
| Simon Quellen Field (Sfield) |
That is likely to work. I haven't tried it. | ||

Hi, I left a message about a week ago asking why our laser kept burning out, and you had suggested that we buy a laser from your catolog...well we did, and we are still incuring the same problem!!! Please Help us!!! |
