Introduction

This tutorial will guide you through the steps of creating a wearable computer, inspired by Zack Freedman's Optigon project. You'll learn about essential components, tools required, and the hacking process involved in modifying existing hardware for optimal performance.

Step 1: Gather Essential Components

Before diving into hardware hacking, ensure you have all the necessary parts.

Step 2: 3D Scanning

Start with a 3D scan of your existing equipment using Polycam.

  • Download the Polycam app.
  • Follow the app instructions to capture a detailed scan of your wearable hardware.
  • Save the scan for reference during the modification process.

Step 3: Disassemble Existing Hardware

Carefully disassemble your existing device to access the internal components.

  • Use appropriate tools to avoid damaging any parts.
  • Keep screws and small components organized to simplify reassembly.

Step 4: Identify the Problem

Recognize the main issue with the current setup.

  • The Epson Moverio BT-40 display may shut off when a display is disconnected.
  • Understand that this may be related to firmware issues.

Step 5: Hacking the Hardware

Engage in hardware modifications to resolve identified issues.

  • Signal Sniffing: Use the Saleae Logic Analyzer to monitor signals and understand communication between components.
  • Replay Attacks: Test if the device can be tricked into thinking a display is connected.
  • Soldering: Apply solder paste where necessary to secure new connections.

Step 6: Testing and Iteration

After modifications, it’s crucial to test your wearable computer.

  • Reassemble the device and power it on.
  • Check functionality of the Epson Moverio BT-40.
  • Iterate on your modifications based on testing outcomes.

Conclusion

In this tutorial, we covered the steps to create and modify a wearable computer, including gathering components, 3D scanning, disassembly, identifying problems, hacking hardware, and testing. As you progress, remember to document your process and share your findings with the community. For further exploration, consider diving into firmware updates and additional hardware enhancements.
