Duino tag is a laser tag system based around the arduino.
Finally a laser tag system that can be tweaked modded and hacked until you have the perfect laser tag system for office ordnance, woodland wars and suburban skirmishes.
Laser tag is combat game like paintball or airsoft without the pain, it uses infrared light (IR) to simulate the tagging / shooting of other players or targets.
I have been working on this project for a while, but don't see it as over, I just though it was time to get more people involved. Hopefully this instructable will be near enough finished in time for me to enter it in the arduino competition, although I expect the instructable will need editing and tweaking for some time to come.
This instructable aims to provide you with the information you will need to go out and build your own duino tagger.
This instructable focuses on how to build a duino tagger by modifying a light gun but with a bit of extra work you could build you own gun from scratch.
This instructable does not look in too much detail at the software / code side of the project, although a working code based on the miles tag protocol is provided.
For those wishing to learn about duino tagger programming I suggest you start at the excellent tutorials found at A Terrible Idea.
Thoes experience arduino users will probably find the overview page (Step 1) and code pages (Step 8) the most useful, newer arduino users may need to take a closer look at the instructable and the links provided.
I hope many of you will find this instructable useful and will go on to build your own duino taggers. There is much scope for improving and upgrading this system outlined here. If you do go on to improve on this duinotagger please share your work and hopefully in time the system will evolve into a much richer gaming experience.

This video shows me using the second duino tagger I made to shoot at a talcapult target I have been working on. I hope to make an instructable about the talcapult soon.
IR Transmitter system
What - Transistor amplifier, high power IR LED and a lens to give a well focused IR beam.
Why - To give the tagger means of tagging / shooting other players as well as communicating game information. The transmitter amplifies the transmission signal from the arduino and transmits it using an IR LED, lenses are used to make the signal very directional in order to make the guns behave like guns and make long range transmissions possible.
What - Peizo Sounder (& mini sound recorder / playback electronics from greetings card)
Why - It’s nice to have some audio feedback from the system. Sound effects to let you know when the tagger has been shot or run out of ammunition or lives.
What - Standard IR receiver module and power regulation capacitor
Why - So the gun knows when it has been shot. This design in this instructable looks at using 3 sensors 1 on the gun as well as front and rear head sensors.
Visual Effects and lights
What - LED’s and bar graph driver circuits
Why - It is nice to get visual feedback on game information, eg lights to let you know when you have been shot.
To make this section internationally friendly; at the time of writing: £1 GBP = $ 1.6 USD = 1.1 EUR
Assuming you already own an arduino the basic extra components for this project can be bought for around £10.
Now is a great time to try to build a duino tagger as it is easy to get hold of cheap second hand light guns. Light guns are the guns that you can use with computer games, many of them don’t work with modern LCD screens and so there are a lot of them going cheap on ebay and else where. I bought two light guns each cost about £4 one off ebay one from a charity shop. Light guns are a great starting point for this project as they provide the optics, switches and case required for the build.
You will need:
Coloured LED’s (preferably 30mA+)
At least 2x IR LED’s matched to the IR receiver (preferably 100mA+)
Power transistor /MOSFET
A few electronics basics: solder, resistors , capacitors.
