README
README.mdOpenLaserTag
OperLaserTag is a DIY system for the popular game lasertag. I have designed it for high flexibility for game modes. With this article series and a little knowledge about electronics with microcontrollers like the Arduino you should be able to build your own lasertag system. The work on this project isn't finished jet and I would be glad to receive some honest hints about what the system should be able to do and how this can be accomplished.
The System consists of the Arduino-based tagger, which is connected to a smartphone via bluetooth. The tagger uses an infrared LED and a lens to send a beam of modulated IR-light in the direction the tagger is pointed to. This works similar to normal IR-remotes, for example for your TV. The tagger is connected to a number of receiver modules, which are located on a vest, so that you can be hit by other players with their tagger. The Arduino informs the smartphone whenever something happens via a bluetooth-serial module and the smartphone does all the management of the game.
At the current state the tagger systems of different players don't have any contact. I designed the system, so that the game follows rules written in a XML-file and will end in a given time limit. This gives great flexibility, because you don't have to set up a communication system over the whole game field (which may be quite big). But this feature (over a limited range) could be added using 433MHz transmission modules.

Questions
How big is the Receiver module PCB?
It measures 47 × 41.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Receiver module use?
20 parts, built around the ATTINY45-20PU, PCF8574AP and BC237. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Receiver module KiCad files?
From the lucullusTheOnly/OpenLaserTag repository on GitHub, at the commit this page was made from: the board is Schematics/Receiver_module.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Receiver module design in my own project?
Its repository states no licence, so its author keeps all rights: ask lucullusTheOnly before reusing the design.
