There are provided systems and methods for a physical stand for multiple device orientations and peripheral card reader. A device stand may include a dock that allows for placement and securing of a computing device within the device case, such as through a locking or connecting mechanism. The device dock further includes a peripheral component, such as a physical card reader, that allows for reading and entry of card data into the computing device for use with an electronic transaction processing application on the computing device. This allows the computing device to process transactions electronic with an online service provider. Further, the device stand includes a hinge or joint that allows for rotating and inverting of the computing device over a curved extension from a base of the device stand, which allows the computing device to be viewed in multiple directions and orientations.

Solar trackers that may be advantageously employed on sloped and/or variable terrain to rotate solar panels to track motion of the sun across the sky include bearing assemblies and other mechanical features configured to address mechanical challenges posed by the sloped and/or variable terrain that might otherwise prevent or complicate use of solar trackers on such terrain.
