Nuts and Volts - May 2010

with the end of the barrel (see Figure 6). Cock the weapon and fire at a blank white wall. Twist the tube for the best alignment. Using an Allen wrench, adjust the three screws until the beam aligns with the sight. Put a drop of white paint or nail polish on top of the tube for relocation the next time.

Using the Laser Sight and Target

There are four programs available: • Double-check the chamber!! After checking that your weapon is clear of all ammunition, dry fire into a safe back-stop, for example a brick fireplace.

I hope you enjoy this project and always stay on target! NV

1. Test. (DIP switch one on, two and three off).

2. Normal. Displays a hit and the score for five seconds (DIP switch one and two are on three is off).

3. Rapid fire. Turns on the LED, and keeps them on (DIP switch one, two and three on).

4. Design your own programs. (Five more DIP switch settings are available).

Turn on the switch and load the photon tube into your barrel.

Work in a semi-lighted room. If it is too bright, it can lock up the target. Place the target on the wall about 25 feet and turn it on. Set the program you are going to use and press reset. With an automatic weapon, you will need to recycle the breach each time. In the normal mode, the hit will display for the five seconds and the score will accumulate with each shot. Press the reset button to clear.

The Rapid Fire mode will display the number of shots. At the end of six shots, the LEDs will light and the score will display. Again, press the reset button to clear. (Note: If two shots hit the same location, only one will be displayed, but the score will be correct.)
