A boost regulator for converting an input voltage to a higher output voltage including an inductor, an error circuit, a switching circuit, a ripple circuit, and a hysteretic comparator circuit. The tool mount can accept a variety of accessory tools which move in a reversing angular displacement as well as articulate throughout the range of positions. A single layer of graphene is formed on the top surface of the silicon carbide. Typically, the CMR film first area is approximately equal to the top electrode area, although the CMR film second area may be less than the bottom electrode area. In the closed position, the first body portion engages the second body portion to enclose the open side, to closely enclose the enclosed portion of the paintbrush, and to provide a base portion for bordering and protecting the plurality of ends to the plurality of bristles.
