When I was practicing with my Air rifle the target used is 40 feet away and the shot goes above or below or sides of the target making it difficult to know. So I planned to make an electronic based indication system that shows where the shot hit. I made small square 4Inch of steel 4mm , 3 on top , 3
down and 2 in the middle, the center sqaure is futher divided into 2 inch x4 squares, and in the center a 3 inch bulls eye. Each has a push button and an ultrabright led on the center of each square, and the bulls eye led is always on for aiming practice. if it it will also blink.I have programmed the microcontroller so if a square is hit the led will blink for 4 times and stay on for about 10 sec so we know where it has been hit. So during practice it goes like this I aim on the Led (bullseye) and shoot, if it goes just 2 inches next to the Bulls eye that sqaure's led would blink so i know where the shot went. now planning to have a wireless lcd unit where we know which sqare is hit. the risk factor here is the led as it is direclty open on the steel , if it hits its gone. have to think of something that can protect it. any more ideas? Any more suggestions?

//the shot goes above or below or sides of the target making it difficult to know// - the electronic hit counter sounds nice, but if you miss it, you still will not know where you missed it... |

Shoot at a large sheet of bulletproof polycarbonate with three microphones attached to the back in an equilateral triangle which pick up the impact of the pellet on the sheet. Analysis of the differences in when the signal reaches the three microphones will give you a position for the point of impact. This can be translated into a synthesised voice telling you "Up and a tad to the right". |

so, just make it bigger. |

[hippo], you should post that as an idea in it's own right. |

It sounds like you've already built something...can you post a picture?? |

I don't have a good sense of how hard an air rifle shot is, and what kind of switches you have. Could you just glue the LED to the switch, and put some clear plastic sheet over it? Or, use translucent pushbuttons? Or, use LEDs that shine on the pushbuttons from somewhere out of the line of fire? Or, put the LEDs off to the side? |
