What this episode covers

Alan Yates, a hardware engineer at Valve responsible for the Vive tracking system, explains the Lighthouse optical tracking technology, which uses spinning mirrors and infrared lasers to achieve sub-millimeter precision. He details the engineering challenges of combining high-frequency IMU data with lower-frequency optical updates using Kalman filters, and discusses the decision to use ST and NXP Cortex-M0 microcontrollers for the 'Watchman' receivers. The conversation covers the transition from 3D-printed prototypes to mass-produced base stations, the importance of hackability, and the community's reverse engineering efforts.

    An interview with Jeri Ellsworth - Absorptive Augmented Actuality

    Jeri Ellsworth, founder of Technical Illusions, discusses the CastAR system, an augmented reality platform using retroreflective projection and low-cost optical tracking. She details her departure from Valve Software, where she led the AR hardware team, and explains how Valve allowed her to take the technology to start her own company. The conversation covers the technical challenges of achieving sub-millimeter head tracking with cheap image sensors, the use of metalized gate arrays to hit a sub-$200 price point, and their strategy to launch via Kickstarter.

    Ep059: Hydraulic Rockets & Presses, Machine Vision Bounces & Stares, Smart Speakers Listen to You

    Hackaday editors Mike Szczys and Elliot Williams discuss several hardware hacks, including Joe Barnard’s silo-launched thrust-vectoring model rocket, which required solving pneumatic timing and sensor failures, and Graham Jessup’s 3D-printed robotic face with machine vision tracking. They also cover Daniel Riley’s solar-powered rover, which overcame steering and traction issues through iterative frame modifications, and a robotic ball bouncer using a parallel manipulator and OpenCV. The episode concludes with an analysis of smart speaker false activations and a discussion of Northrop Grumman’s Mission Extension Vehicle, a space tow truck designed to extend satellite life in geosynchronous orbit.

    Garbage Ninjas

    Dave Jones and Chris Gammell discuss the engineering and marketing behind fitness trackers like the Fitbit Inspire 3, analyzing its sensors, Kalman filters, and the history of the 10,000-step metric. They review teardowns of the Fitbit and a 1980s boom box, highlighting component choices from STMicro and Maxim, and discuss the business of selling teardown reports via Yole Group. The conversation shifts to supply chain realities, including Chris Gammell's experience with Macrofab's DFM reports and the collapse of Tempo Automation, before touching on a compact RISC-V core implementation in Verilog.

    Building AR Headsets with Aedan Cullen

    Aedan Cullen, a recent college graduate, discusses his four-year hobby project to build a compact, low-power Augmented Reality (AR) headset. He details the evolution of his hardware designs, moving from an Allwinner RISC-V SoC to an NXP i.MX RT500 microcontroller, and explains the technical challenges of driving high-resolution OLED micro-displays via MIPI DSI. Cullen also covers the system-level trade-offs between Wi-Fi and Bluetooth for content streaming, power management strategies for all-day wearability, and the mechanical and optical hurdles of integrating displays into eyewear form factors.
