One of my brothers friends asked if he could design and build a shooting timer. My brother like challenges and the result is the shooting timer shown on this page. The shooting timer can be used during shooting practice in the disciplines:
1) 25 meter standard pistol,
2) 25 meter sport pistol and
3) Terrain pistol.

The shooting timer PCB. Now with firmware version 9 with these enhancements: 1) Instead of using pause commands to control the time in the program, it now uses timer interrupts 2) Default values for the timer interrupt are located in the internal eeprom. These values can be adjusted to obtain higher accuracy 3) Category 3, discipline 1-3, can be changed by the user to others shooting intervals. The shooting parameters are located in the internal eeprom.
