The specification discloses a hand-held detonator or blasting device which includes a rigid housing dimensioned to be held in the hand of an operator. A pair of binding posts extend from the housing for attachment to an explosive charge. First and second switches are mounted on the housing and a battery and capacitor are disposed within the housing. An oscillator is provided for being connected to the battery in response to operation of the first switch to generate an A.C. signal. A transformer is connected to the output of the oscillator to apply the A.C. signal to full-wave rectifying circuitry which produces a D.C. signal in order to charge the capacitor to a predetermined voltage level. Circuitry is responsive to operation of the second switch to disconnect the capacitor from the battery and to connect the capacitor across the binding posts in order to discharge the voltage stored thereon to detonate the explosive charge. Numerous safety features are incorporated within the device to prohibit undesired detonation of the explosive charge.
