Laser Shooting Range (laser Gun+target)




Introduction: Laser Shooting Range (laser Gun+target)

Laser Shooting Range (laser gun + target)

Have you ever dreamt of becoming a marksman? I can help you! You need a laser pointer, few electronic parts, some trash and 3-4 hours. The target can be stationary and moveable. You can practice as much shooting as you like. Let’s come to the point.

Step 1: Materials and Tools

Materials and Tools

1 milk carton (for a target)
1 shampoo bottle (for a gun’s barrel)
1 body deodorant enclosure (for a gun’s grip)
color paper (to make a mask and decorate a target)
blister (to shield LEDs )
thread (to hang a target)
duct tape
double-sided adhesive tape
a laser pointer
felt pens
4 small bolts with nuts (washers are optional)

Electronic parts:
For a laser gun – a 2200mF/10V capacitor, a press on/off switch(for a trigger), a 3AA battery holder, a 3V buzzer (with in-built generator), a small switch (to activate a buzzer).
For a target – 1 PNP germanium transistor, 1 NPN transistor (BC547), 1 resistor 1K3/0,25W, 1 speaker 8 Ohm/0,25W, 2 LEDs(red/3mm), 1AA battery holder, a small switch, a phototransistor.

Step 2: Target Schematic

Target schematic

The schematic is a modified RL-oscillator. I added 2 LEDs and a phototransistior. Note: it is important to use LEDs with the lowest working voltage (under 2V). You cannot substitute a germanium transistor with a silicon one.

Step 3: Target's Electronic Work

Target’s electronic work

You needn’t a PCB. Solder transistors, a resistor and wires to the speaker’s lead-outs. When you are done, test the target. As soon as you expose the phototransistor to the light the LEDs will be on and the speaker starts beeping.

Step 4: Mask


I am fond of origami. If you don’t want to be bothered with folding you can draw a picture then cut it out and paste on a piece of cardboard. Punch holes in the eyes to install LEDs. Punch a few holes on the nose just opposite the speaker. Punch holes in the mouth to install a small switch. Punch holes in the bowtie to install a phototransistor.

Step 5: Target's Assembly

Target’s assembly

Cut out a flap on the side of the milk carton to get an access inside. On the opposite side cut out a hole just a bit smaller than the outer diameter of the speaker. Above this hole, where you suppose cat’s eyes should be, punch holes for the LEDs lead-outs. Punch holes just under the cat’s mouth to install a small switch. Punch holes in the center of the bowtie for the phototransistor’s lead-outs. Fix the speaker with Superglue. Solder wires to the LEDs, the phototransistor and the switch. Fix the battery holder with duct tape on the bottom. Fix pieces of blister over the LEDs with Superglue. Decorate the sides with color paper, secure edges with adhesive tape. Punch holes in the upper part of the milk carton. Take a piece of thread and get it through the holes, tie the ends in a simple knot. The target is ready.

Step 6: Laser Gun Schematic

Laser Gun schematic

You needn’t a PCB. The buzzer with a small switch is hooked in parallel with the laser pointer. So if you don’t want a sound effect you can do without them.

Step 7: Gun's Electronic Work

Gun’s electronic work

Having done soldering, keep the construction under test. Insert batteries and press the button on the trigger, the laser pointer flashes and the buzzer beeps.

Step 8: Gun's Assembly

Gun’s assembly

Make holes in the shampoo bottle. I made them with a craft knife, hot wire and a hot nail (for bolts). Make holes in the body deodorant’s enclosure. Secure 3AA battery holder inside the shampoo bottle just above the grip(deodorant’s enclosure) with 2 small bolts. Make 3 cuts on the deodorant’s enclosure to mount the trigger switch. The trickiest job is to solder a capacitor and wires to the trigger switch. Make a few turns of duct tape around the laser pointer to hold the button pressed and insert the pointer inside the barrel. Solder the other parts. Secure the grip with two small bolts. The laser gun is ready.

Step 9: Engoy Shooting!

Enjoy shooting!

The optimal distance is 4-5m. If you feel boring to shoot at a stationary target, try to hit a moveable one. Hang the target in a proper place and make a few rotations, after releasing the target starts spinning.

    How long does the laser pulse last?

    Hi! I've been thinking about making this, but I've been having problems finding all of the pieces that you listed. Do you think you could you email me a list of sites or places where you found the materials? My email is Much appreciated, thanks!

    Hello, it is a great project. Is the battery conected in the wrong way? please can you correct the schematic please? Regards.

    I'm looking to purchase a lazertag system to start a lazertag business,
    would you be able to produce or lead me to the guns and equipment I need
    that would be safe and certifiable, that would be a cheaper option than
    the $600/gun price range that I've seen advertised by the lazertag
    manufacturers? email if so at

    great idea!

    fyi: you may substitute a silicon transistor for the germanium(hard to find nowadays), but you need to redesign the receiver circuit...

    Does the gun work If we use LED instead of laser light?


    Reply 10 years ago on Introduction

    Yes. But I don't think it's worth replacing a laser diode with a LED. Laser diode is used because it is much brighter and it gives a smaller light spot at a target(shooting distance - 2-5m.). If you don't have a laser diode, you'd better use a superbright LED with an optical system (magnifying glass) at a gun muzzle.
