![]() This project includes Gerber files, the source code, BOM, and production hex file to program the PIC16F627A micro-controller. Battery snaps that are riveted to the PCB were used to connect the four-cell “AA” battery pack to the unit which also serves as the handle for the laser tag phasor. You can see the black tubes on the IR LED’s in Picture 1. If you wish to limit the hit angle, a small piece of tubing can be glued to the IR sensor to limit the angle of incoming IR signals. When building the units, put black shrink wrap tubing around the two IR LED’s to narrow the IR beam. PZ1 outputs the sounds and its output is reduced by resistor R1. The Green, Yellow and Red LED’s show the number of hits, 1, 2, 3 respectively. Further, D6 drops the voltage to 5.4 volts to keep the circuits voltage at a safe level for U1 and U2. Diode D6 prevents damaging the circuit if a reversed polarity voltage is connected to the circuit. V1 consists of a battery pack that holds 4 “AA” batteries. Pressing S2 causes the unit to send out a burst of 256 Infra-Red pulses at an 8% duty cycle and a 40 KHz rate, via Q1, D4 and D5. The ON/OFF switch must be turned OFF and then ON to reset the unit and make it operable. Micro-controller U2, a PIC16F627A, has programming that records the number of hits, flashes the proper LED’s and makes sounds related to power-up, recorded hits, and dying after four hits. When it sees an Infra-Red pulse train at 40 KHz, its output goes low, otherwise it remains high. U1 is a 40 KHz IR sensor used in many products that utilize IR remote controls. There are two IC’s that are the core of the Laser Tag Phasor, (LTP). Each Laser tag unit has a trigger to shoot the laser pulse and three LEDs to indicate how many time you have taken hit and buzzer to sound when taken a hit or indicate game over when taking more than 3 hits.Ĭircuits Library - 220+ practical circuits My kids used to play laser tag with them a lot when they were young. Moving on, I built the units shown in Picture 1. The company that hired me loved the result. I developed the circuit and it worked really well. They could remove the units from their shoes and play laser tag. Many years ago, a company hired me as a consultant to develop a simple Laser Tag unit that could be put in an oval housing and attached to kids shoes. If you are not aware of this game, here is an article that could help you to get up to speed. This article shows only two pieces however you can build as many as you want based on the number of participants in this game. This project demonstrates working and building a Laser tag phasor gun that can be used to play Laser tag game. Be it a party or get together a little fun game can make things interesting. Who doesn’t love playing games with friends and family.
