Hi,
I wonder if anyone here has any experience with those
little hand held laser toys that project a thin beam,
for quite a distance.
I have one that is intended as a toy to play with cats
they chase the spot around. Its only small, it takes
three tiny cells, giving four and a half volts.
I'm thinking of trying to use it as a 'break the beam'
type intruder sensor.
But i don't know if it will run continuously or not.
Maybe i could reduce battery voltage to increase its
length of life?
Maybe running it on reduced voltage could de-crease
its life expectancy ?
Maybe i could pulse the supply with short on mark/space
time ratio high frequency pulses ?
Maybe i could expect 5 years as it stands ... ?
I have no experience of these at all,
any advice would be welcome.
Regards, John
