A magnifying container assembly for storing and improving the visibility of items stored within the container assembly includes a base section and at least one wall section extending away from the base section. The base section and at least one wall section form an enclosure that can receive at least one item within the enclosure. At least a portion of the at least one wall section may include a transparent magnifying region that magnifies an item or items retained within the enclosure. The container may include a plurality of magnifying regions with differing degrees of magnifying powers. The base section may include grooves, ridges, or other retaining element or elements to retain an item in a particular position within the container. When an item is disposed within the container the at least one magnifying region facilitates and improves viewing of the contents of the container.

A supply circuit for supplying a light-emitting element includes a voltage regulator having a voltage output for outputting an output voltage and having a control input for regulating the output voltage based on a voltage at a divider node of a voltage divider. A first and a second terminal are used to connect the light emitting element, the first terminal being coupled to the voltage output and the second terminal being coupled to a reference potential terminal via a series resistor. The supply circuit further includes a control block having an analog-to-digital converter for generating a digital voltage feedback value from a voltage applied to the second terminal, a control element, and a digital-to-analog converter coupled to the divider node for outputting an analog control signal based on a digital control value.
