In one aspect, an electronic apparatus may include a base and an electrode. In one embodiment, the electrode can be cylindrical with a threaded portion on top of the electrode, and the threaded portion can be used to secure another electronic device with corresponding threads. For example, the electrode can be used to connect with a camera having an electrode and a corresponding threaded portion. More specifically, the camera can be secured on the electrode through the threaded portions and when the camera is fully secured on the electrode, the electrode can be in contact with the electrode to electrically connect with the camera.
