Project Overview Objective: Create an autonomous gantry to follow the HTC Vive headset around, keeping its cable behind the user at all times. Motivation: An extravagant party prop for an evening at CES 2017, hosted by MistyWest. Features: CoreXY planar gantry design System built with 8020 aluminum extrusions and laser cut acrylic components Stepper motor control through Teensy 3.2 HTC Vive pose tracking through C++ Patent pending Skills:
Originally posted on Medium under MistyWest. Virtual reality pushes the envelope of bleeding edge technology, allowing us to explore and experience worlds beyond our mortal imaginations. It gives us immersion in another dimension, providing an unprecedented medium for communication and story telling. If a picture is worth a thousand words, then virtual reality must be worth millions. Except there’s one thing keeping it grounded to reality: cables. Since the first virtual reality headset that was hacked together in 2011, immersive head-mounted displays have progressed far and quickly.

Background: Welcome to TZOA (pronounced ‘zoa’) - the world’s most advanced environment tracker. TZOA uses internal sensors to measure your air quality, temperature, humidity, atmospheric pressure, ambient light, and UV (sun) exposure, all in one wearable device. Objective: Design and build a purified test chamber with zero air particulate to calibrate the TZOA devices against the DusTrak DRX 8533. An aerosolized cloud of ultrafine (0.3 - 20 μm) test dust was used to create the particle events.

Foam liners in bicycle helmets absorb energy during impacts. Manufacturers recommend replacing a helmet every 2 to 10 years to maintain optimal head protection. To investigate this recommendation, we quantified the material and impact attenuation properties of helmets to determine if they changed with age.
