US Patent 12011563 Devices and methods for controlling needle reciprocation

An electronically power-adjusted tattoo machine, power supply, and methods for controlling needle reciprocation are disclosed. The dynamic power adjustment controls needle impact force of a tattoo machine through electronic circuitry which establishes a baseline current of a tattoo machine motor, monitors current drawn by the motor, and increases or decreases the voltage provided to the motor as the current changes. The rate and degree of voltage adjustment may be varied by user-defined settings.
