Title: Arrow construction system having tip canister electronics

Abstract: An arrow construction system comprising a tip canister configured to receive an arrow tip and to attach to an arrow shaft. The tip canister contains a power source and sensitive electronics. The power circuit may be a battery, a primary storage capacitor, a coil and a rectifier, and/or a solar cell. The tip canister may be electrically connected to the nock via the shaft electrical conduction system. The electrical conductors may be integrated into the shaft. The wires may form a cable with standard connectors. The nock may contain a light. Alternatively, the fletching may comprise light emitting film or fibers. The circuits may include a flash circuit, an audio circuit, a radio beacon, a wireless transmitter, environmental sensors, a camera, a switch, and/or a GPS device.
