TI-H: Laser Network (OT)
I had an idea earlier today, to make a secure and wireless network...
You could use a 10BaseF tranciever (the ones that have two fiber
connections, i take it that one is transmit and one recieve) and replace
the transmitter with a laser diode (maybe extra circuitry) and use a
different reciever. With a few mirrors you could focus the laser beam
into a reciever (say a photodiode...) and it wouldnt require much to
make an aiming device, if the entire arrangement was bolted to something
secure, say a window sill or something. I have a rough idea on how you
could make an automatic aiming device using another mirror and another
laser with a few photodiodes and small servos. The laser would be
completely secure, it would be almost impossible to infiltrate the beam.
The only disadvantage would be that it would be rather expensive...
anyone got any other ideas?
