Creating your own laser tag gun may not give you as pretty a gun as one made commercially, but it will show others who play the game that you are a individualist to be taken seriously. The process requires purchasing an inexpensive green laser pointer, some electronic parts from an electronic store or hobby shop and extensive knowledge of electronics.
- Skill level:
Things you need
- Green laser pointer
- Toy gun
- Soldering iron
- 3-foot electrical wire
- Wire strippers
- Portable drill
- PIC16F628A microcontroller
- 18-pin PIC16F628A IC chip
- 3-pin 5V voltage regulator IC chip
- Piezo transducer
- 4-pin female DIN socket
- 4-pin male DIN socket
- 5-volt battery compartment
- 5-volt button battery
- Silicon gel
Strip the positive and negative connections on each end of the 3-foot electrical wire using the wire strippers.
Remove the battery cap and batteries from the green laser pointer.Twist open the green laser pointer. Solder a microswitch to the positive and negative connections of the green laser pointer's on/off switch. Solder the positive and negative contacts on the microswitch to one end of the electrical wire.
Drill a small hole in the bottom of the stock of the toy gun. Insert the electrical wire through the barrel of the toy gun and out the small hole in the bottom of the gun.
Drill a small hole about halfway down the barrel of the toy gun.
Solder an 18-pin PIC16F628A IC chip to the appropriate 18-pin position on the PIC16F628A microcontroller board.
Solder a 3-pin 5V voltage regulator IC chip to the appropriate 3-pin position on the PIC16F628A microcontroller board.
Solder a Piezo transducer to the appropriate position on the PIC16F628A microcontroller board.
Solder a 4-pin female DIN socket to the appropriate position on the PIC16F628A microcontroller board.
Solder a 5-volt battery compartment to the positive and negative contacts on the 5-volt voltage regulator IC chip.
Solder the positive and negative and ground wires of the electrical wire to a 4-pin male DIN socket.
Connect the 4-pin male DIN socket to the 4-pin female DIN socket.
Solder the PIC16F628A microcontroller board onto a piece of stripboard.
Insert 5-volt button battery into the battery compartment.
Drill a small hole at the rim of the two halves of the green laser pointer. Put the two halves together so the electrical wire is inside the hole.
Insert the batteries into the green laser pointer and close the battery cap.
Insert the green laser pointer into the barrel of the toy gun until the on-off switch can be seen in the hole in the barrel. Apply silicon gel around the on-off button to secure it in the hole. Let the gel dry.
Pick up the toy gun and fire the green laser pen at a laser tag target by pressing on the on-off switch. Listen to the sounds made as the laser gun you have made hits the laser tag target.
Tips and warnings
- Carry spare batteries to keep the laser tag gun fully "armed" for use.
- Wear protective goggles to keep the laser light from damaging your eyes.
