Various embodiments of a wirelessly powered local computing environment are described. The wireless powered local computing environment includes at least a near field magnetic resonance (NFMR) power supply arranged to wirelessly provide power to any of a number of suitably configured devices. In the described embodiments, the devices arranged to receive power wirelessly from the NFMR power supply must be located in a region known as the near field that extends no further than a distance of a few times a characteristic size of the NFMR power supply transmission device. Typically, the distance can be on the order of 1 meter or so. The NFMR power supply is used to tune a transmitter in order to maintain a high Q factor.
