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.

Materials and Tools
1 milk carton (for a target)
1 shampoo bottle (for a gun’s barrel)

color paper (to make a mask and decorate a target)
blister (to shield LEDs )
thread (to hang a target)
double-sided adhesive tape
a laser pointer
4 small bolts with nuts (washers are optional)
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.
