Halo Reach Energy Sword

This project is an ongoing endeavor. The initial model was adapted from the Yeggi Halo Energy Sword project, available at https://www.myminifactory.com/object/halo-energy-sword-3117. Each individual part was reassembled within blender, then hollowed out and recut into new components. The LEDs were assembled and soldered together in a chain. A sheet of packing foam was cut to fit the interior of each sword piece, holding the LEDs in place and diffusing the light. Audio control is handled by the Adafruit ProTrinkit, which takes input from a 3-axis accelerometer. When the ProTrinkit detects a change in acceleration, it triggers the sound board to either play a swing or clash sound based on the magnitude of the change. The LEDs are also controlled by the ProTrinkit through a simple npn transistor, connecting the LEDs to ground when triggered. The device is powered up with a momentary push button. A 2.5W amp powers the speaker, which is hidden inside the LHCAP and RHCAP hilt parts. The code currently functions, but it still requires refinement. All of the sword parts are best printed standing upright at present. However, this causes the layers to crack if the sword is struck hard from the side. To overcome this issue, the sword parts are being recut to allow for a different print orientation. As a result, the layers will go along with the length of the sword rather than against it.
