Hello
I have a project in mind that requires sensing a pellet fired from an air rifle while in the air. Basically its for a target system that auto scores you.
My first thought was to use infrared leds and sensors but as I need to create a grid of beams with no more then 4mm spacing I think IR will not work. So im onto an idea with lasers and photodiodes.
I plan to use an MC that loops very little code then uses functions to workout the score once 1 or more beams have been broken.
My questions are:
1, is there a better break beam method more suited?
2, if not is there a laser that will shoot out a flat beam say 6-8mm wide?
3, will the photodiode react fast enough as the pellet will only break the beam for a nano
second?
Naturally using a switch that requires a pellet to touch is out the question. These high power rifles have gone through metal thats designed to catch the pellets.
