Fiberoptic mouse with quadrature encoders and custom shutter buttons

TL;DR

This project showcases a fiber-optic mouse that uses quadrature method to sense movement and has added buttons that block light to indicate clicks.

Transcript

hey guys then here this is a fiber-optic mouse that is similar to another project that I showed on YouTube the fiber-optic joystick so it's a standard computer mouse that does not contain any electronics or any wire at all actually all of these are fiber optics and it senses the direction through a quadrature method and uses the existing encoder wh...

Key Insights

• 🖱️ Fiber-optic technology can be used to create computer peripherals like mouse and joystick without traditional electronics or wires.
• 👻 Quadrature method allows for precise sensing of movement direction and speed.
• 💿 Telecommunications fiber optics can be repurposed for connecting the fiber-optic mouse to a receiver.

Questions & Answers

Q: How does the fiber-optic mouse sense movement?

The fiber-optic mouse uses a quadrature method, which involves optical channels and encoder wheels. By sensing which phase leads the other, the direction and speed of each axis can be determined.

Q: How is the fiber-optic mouse connected to the receiver?

The mouse is connected to the receiver using telecommunications fiber optics. Standard ST fiber optic connectors are used, with the ceramic ferrule removed to mount the fiber optics in the mouse.

Q: What components are used on the receiver side?

On the receiver side, Vago HF be our series transmitters and receivers are used. The transmitters provide a steady source of light, while the receivers are wired to a microcontroller for quadrature decoding.

Q: How are the buttons added to the fiber-optic mouse?

The buttons are existing mouse buttons from the original mouse. The fiber optics are mounted in the button body, and a shutter is added to block light when the button is actuated, indicating a click.

Summary & Key Takeaways

• The fiber-optic mouse is made entirely of fiber optics, with no electronics or wires.

• It uses a quadrature method with optical channels and encoder wheels to sense movement.

• The mouse is connected to a receiver using telecommunications fiber optics, and has added buttons with light-blocking shutters for clicking.
