Abstract: Some embodiments described herein generally relate to a solar device with a removable cassette. The removable cassette is configured to dock with the solar device such that, in an engaged position, it may receive electrical energy generated from solar energy by a solar panel of the device, from internal batteries charged by the solar panel or an external power source. The cassette may include at least one of a battery and a power-consuming accessory, such as a wireless router, data storage, an output adapter, or the like. The internal batteries are configured to charge the cassette in cases where the solar panel is not generating electrical energy because of dim lighting or lack of lighting.

Abstract: In an embodiment, a device is described that includes a computer-readable medium, a processing device, and an MCUI. The processing device may be configured to execute computer-executable instructions stored on the computer-readable medium. The MCUI may include computer-executable instructions stored on the computer-readable medium. The computer-executable instructions may include instructions for processing data representing movement of the device to actuate one or more features of the device. Each feature may be designated on the device by a corresponding feature icon. The computer-executable instructions may also include instructions for providing, on the device, an indication of which feature is actuated on the device. The indication may be associated with a feature icon corresponding to an actuated feature.
