20 A grip frame 21 replaces an existing grip frame 1 on a paintball marker in order to convert said paintball marker from a mechanically operated paintball marker into an electro-pneumatic paintball marker. The electronic grip frame 21 utilizes an optical sensor in order to detect the operation of a trigger 29 and a second optical sensor to detect the presence of objects within the breech of the paintball marker. Electrical signals from these sensors are taken to an electronic circuit board 24 , which controls the operation of two solenoids (one shown 26 ) in order to fire and recock the paintball marker. A user interface comprising pushbuttons 12, 13, 14 and a multi-character display 16 , allows the user to define how the grip frame 21 functions. |
