A powergating circuit includes a P-channel transistor with a source coupled to VCC, a gate for receiving a first boosted or non-boosted powergating control signal, and a drain forming the internal switched VCC power supply. An encoder converts a pixel stream to digital sample values for a target analog signal at a base sampling rate. The LED is coupled at a drain of the driver transistor and the driver transistor drives current to the LED. In varying examples, the tool can include a pick portion that is sized and shaped to fit at least partially within an opening of a culinary nut and have sufficient stiffness to allow the culinary nut to be pried open.
