Abstract:
1. A nailer or stapler device comprising: a solenoid; a fastener striker in operational communication with the solenoid; a flash capacitor in operational communication with the solenoid, the capacitor operating at 400 or more microfarads and having a charging capacity of at least approximately 180 volts; and, a control circuit in operational communication with the flash capacitor, the circuit configured to both substantially charge the flash capacitor by at least 180 volts from a direct current battery and substantially discharge the capacitor within approximately 3 seconds or less, the battery having a charging capacity of at least approximately 12 volts, the control circuit including a high voltage generation circuit having a transformer for converting the voltage supplied by the battery to a higher voltage for charging the flash capacitor and a microcontroller configured to control both the operation of the high voltage generation circuit and the charging of the flash capacitor.
