This shooting simulator is a
further development of the previous build voice module for the speed timer.
Instead of using a separate control unit and a separate voice module it
gathers it all in one single apparatus.
To operate the shooting simulator you only need one button. Pressing it
briefly corresponds to “No”, while pressing and holding it for a short while
corresponds to “Yes”.
When you power on the shooting simulator you can choose between 3 different
kinds of shooting disciplines: standard pistol, sport pistol and terrain
pistol. Each time you select a new discipline it will tell you the
discipline name.
When you have selected one particular discipline you can choose between 2 to
4 different categories. Once again it will tell you the name of the selected
category. When you select a category it asks you if you want to repeat the
shooting. By pressing the button briefly it will only run one time. If you
press and hold the button for a short while, the selected category will be
repeated for 250 times. You can always during action interrupt the shooting
simulator simply by pressing the button. It will then return to the selected
category. Below you can see some pictures of the design (click on the picture to enlarge it):

The voice commands are stored in a
18F4620 PIC, converted to speech in a R2R DAC and filtered through a
4'th order low pass filter. The filter op amp is powerful enough to
drive a pair of headphones directly. |

battery, using approx. 25mA, which result in around 20 hour battery life. |
