We have built a versatile and reliable "Laser-Force" simulator for only $20. The system is very easy to put together, is reliable, and would be great for a school lunchtime activity and home use. The Laser-Wars system uses a PICAXE-08 chip that is very affordable and very easy to program using free software. Pulse Rifles use the flash from disposable cameras supplied by the local Kodak camera store free of charge. We are very happy because it is much cheaper than the 'professional' made laser gun that averages at about $500 for the vest and gun. Our Laser Wars is fun to play at night but still works efficiently in day light therefore its better than the original "Laser Force" version.

Results and Discussion

There is a business in New Plymouth that is called "Laser Force". It is a game you play inside where you shoot people with "laser" guns hence deactivating their suit and gun and scoring points for yourself. We have noticed is that it has to be dark for the guns to work properly making night time the most ideal time to play this game outdoors. Our version of this game works at night but still works efficiently in daylight therefore it is better than the "Laser Force" idea.

We have successfully tested many parts to make it a satisfactory device and carried out extensive field tests. We plan to add a sound effects chip to the Pulse Rifles and make different types of "weapons", eg, pistols and grenades.

Conclusions

This simple inexpensive and reliable device would be a great addition to any child's toy box and any schools Physical Education (PE) department. Our "Laser Wars" system is versatile because you use more then one type of light. If we use a PICAXE-18 we can run about 4 or 5 different lights all at once. It is good because you do not need lots of other PICAXE chips and it can store more data. Students could use this "Laser Wars" system to make lunchtimes less boring and more fun.
