Electronic Chime Sound Target For Laser Pistol




This shooting target are used for shooting practice with laser pistol. The laser gun is made of a modified laser pointer with a pistol handle and a pulse-shaped laser beam that resembles a bullet passing through.

Shooting target is made of stainless steel cup. There is a hole in the center of the target paper, if the laser beam hits the center (bullseye) then the laser beam is entering the cup and reflected. Since the target paper is smaller than the cup's mouth, the reflected laser beam can be seen as a luminous outer ring. See the following video:



An electronic circuit can be applied to this shooting target to create chime sound like bell or like steel hit by a bullet when bullseye. See the following video:

Sasaran Elektronik Berbunyi Denting Untuk Pistol Laser




Sasaran tembak ini digunakan untuk latihan menembak dengan pistol laser. Pistol laser tersebut dibuat dari laser pointer yang dimodifikasi dengan gagang pistol dan sinar lasernya berbentuk pulsa sehingga mirip peluru melintas.

Sasaran terbuat dari mangkok stainless steel. Pada bagian tengah kertas sasaran terdapat lubang, jika sinar laser tepat kena bagian tengah (bullseye) maka sinar laser masuk ke dalam mangkok dan terpantul. Karena kertas sasaran lebih kecil dari mulut mangkok, maka sinar laser yang terpantul dapat terlihat sebagai lingkaran luar yang bercahaya. Lihat video berikut:



Sasaran tersebut dapat ditambahkan rangkaian elektronik agar berdenting seperti lonceng atau seperti baja yang terhantam peluru jika bullseye. Lihat video berikut:

Laser Pointer Pistol With Optical Target




Laser pointer  in the photo above has a wooden handle as hand grip and becomes a laser gun. Laser is activated by pulling the trigger. There is a circuit that use a condenser in order to turn on the laser for less than 1/4 seconds. The laser pulse is like a bullet flying to target, watch below video.



By using a simple switch, the laser can be set to turn on continuously, and can be used as a pointer, such as for presentation at the office.

The shooting target is shown below. The target will deflect the laser beam and project the beam as a line on to a wall or screen at the back of that shooting target. So it can be noticed if the target hit by the laser beam. If laser beam doesn't hit the target, then the laser beam will be seen forming a bright small point on the wall at the back of shooting target.



In the following video. shooting target will project laser beam on to the wall and form star-shaped if the target hit right in the center (bullseye).


If the target hit on it's side, the laser beam will be projected on to the wall and form a line. The following video shows the laser beam of pointer hit every sections of target.


Because the laser beam can still be switched on continuously, so this laser pistol still can be used as a pointer for presentations.
