We present the design of a compact electric discharge device incorporating hard disk or optical disk drive actuators. It is simple enough to be assembled in the absence of a mechanical workshop. The electronic circuit allows the adjustment of current, voltage, and discharge power. The system has been tested with organic dielectric liquids and deionized water and spark conditions; dynamic properties and machining characteristics were investigated. This device can be used to shape materials or to produce powdered samples with low material loss and minimal liquid consumption. (C) 2011 American Institute of Physics. [doi: 10.1063/1.3673468]
