LASER RANGE

LASER RANGE – LASER PAINTBALL: YOUR GUN AND AN INTERACTIVE TARGET

Welcome to my instructables. It is about a shooting kit including a laser gun, offering the possibility to aim at objects in a far distance. But how would you know if you hit or not? For this purpose I created a photo-sensitive target, that will let you know when you hit the spot – it will simple „yell“ by the means of a buzzer. But the same target could be worn to your chest in a clean version of paintball.Try it out – and don‘t forget to wear laser-glasses to protect your eyes… I hope you‘ll have some fun building and playing. :-)

Step 1 PDF Complete Project

Here you can find all information necessary to create the laser gun and the interactive target.
The circuit is taken from the journal "Elektronika dla wszystkich" by Piotr Górecki.

Wheer do you attach the pototransistors to, i know you attach it to the circut but where exactly do u do it?

[jeremyzoo]

the positive legs (shorter one) of the phototransistors are attached to R2 10k resistor the negative legs are attached to the R1 10k resistor – which I have replaced with an 10k potentiometer

Ok, thanks.
In the video i just love the smile at the start!
I know that feeling aswell!
and good job at winning third prize:)

What capisitator is it?? Thanks or the diagram it only says c1:(
thank
liam

[jeremyzoo]

Hi liam
everything is written on the diagram, under the C1 capacitor you can see 100nF note that it is an ceramic capacitor it has no poles, the C2 capacitor is electrolytic (it has poles)

Good luck!

ok, thanksyou. For this instructable or a future one, i would highly recommend steps by step on the circuit. Because many people would not try this because they do not get the diagram ( which way the resistors go ect)

HI,
Could you please define Phototransistor type.

[jeremyzoo]

Hello, the code of the phototransistors I used is L-53P3C, but i think it should work also with others. By choosing them do not forget that they have to be transparent to react with the laser.
Good luck!

Cool, I love laser-tag and a DIY version makes it even better.

I like this project, but one thing:
For lasertag e.g. you use glas fiber to conduct the light, so that you can cover a bigger area with less diodes.
I would say, that would make it a lot easier for you too.

interesting. you should add a panel on the gun telling wether or not there has been a "hit" or not. 

[tahwer]

interesting and outstanding.......

[jeremyzoo]

thank you i really appreciate that!

You'll shoot your eye out.

We have had Laser Tag here for decades using the same technology.
Nice video. You captured the light and sound well. An interesting project.

Question- Is that you in the main photo? If so you look a heck of a lot like my self :P

[jeremyzoo]

yes thats me :)
