It consists in a resistor network for convert bits in voltage. The left operational amplifier doubles the voltage. The right, limiting the current flows on base of the power transistor. The left potentiometer adjusts the multiplication factor. The central potentiometer represents the load. The right potentiometer regulates current. Thanks to the community to contribute half of this circuit.
