Can I visually display controller inputs on my stream?

Q: What is the TinyControllerWebDisplay Input Viewer? A: The TinyControllerWebDisplay Input Viewer, created by @Freyaday , is a tool designed for OBS streamers who use rectangle devices. It enables viewers to see the inputs being made on the device in real-time during a stream.

Q: How does it work? A: The tool functions by interpreting the device inputs. Although it lacks access to the exact button inputs—making it somewhat imprecise—it intelligently guesses which mod buttons are pressed in ambiguous situations. It is designed to be adaptable to alternative firmware and doesn't require webserial for its operation.

Q: How can I set it up in OBS? A: To integrate the TinyControllerWebDisplay Input Viewer into your OBS setup, follow these steps:

  1. Visit the GitHub repository: TinyControllerWebDisplay to download the HTML file.

  2. In OBS, look for the "Browser" source option where you can input a URL.

  3. Start the URL with file:/// followed by the path to the HTML file in the folder you've downloaded. You will be to uncheck local file.

  4. Customize the layout by adding suffix parameters to the file name in the URL. ?type=gram

  5. The initial display might be small, so adjust its size in OBS to fit your stream's layout preferences.

Q: Are there any limitations? A: Yes, the tool doesn't capture every exact button press due to its method of operation. It may not accurately display all mod button presses in every situation due to the guesswork involved. However, it's still a valuable tool for showing general input activity without needing webserial access. Enjoy streaming with the TinyControllerWebDisplay Input Viewer!

Care & Ergonomics

How should I clean my GRAM Digital Controller?

Regular cleaning is crucial. Use a dry microfiber cloth for the surface to avoid scratches and for tight spaces, compressed air or a soft-bristled brush is ideal. Avoid any liquids to prevent damage to the electronics.

What's the best way to store my controller?

Keep your controller in a cool, dry place away from direct sunlight to protect the plastic components and internal mechanisms.

How can I protect my controller from damage?

Handle your controller with care to avoid drops or impacts. When transporting, use a protective case or pouch to prevent potential damage. Consider using the Official GRAM Soft Case

Why is it important to update my controller's firmware?

Firmware updates can enhance your controller's functionality and fix software issues. Check for updates periodically and follow our Discord for the latest firmware news.

How do I use my GRAM Digital Controller ergonomically to prevent hand pain?

The design of GRAM Digital Controllers supports natural hand positioning, akin to typing on a keyboard. To ensure ergonomic use and minimize hand strain, consider the following tips:

  • Hand Positioning: Hold your hands on the controller as naturally as you would on a keyboard, aiming for a relaxed grip without excessive tension.

  • Wrist Alignment: Maintain neutral wrist positions to avoid strain, keeping wrists straight without bending up or down excessively.

  • Proper Posture: Sit upright with a straight back and relaxed shoulders, similar to an optimal typing stance. Ensure your arms are positioned comfortably to hover above the controller.

  • Regular Breaks and Stretching: Incorporate breaks into your gaming sessions to rest and perform gentle stretches for your fingers, wrists, and arms.

  • Customization Options: Explore customization for your controller, including 3D printing buttons that meet your ergonomic needs. The open-source community may offer additional customization ideas to enhance comfort and gameplay.

  • Palms Positioning: Hovering your palms rather than resting them on the controller is often recommended for better ergonomics, especially with controllers like the Gram Slim where button elevation could lead to unnatural wrist angles.

What layouts are considered more ergonomic?

The HTangl and Hadoe layouts are designed with ergonomics in mind, positioning the B/X/Z/Up row on top, which might require hovering the palms. This layout aligns with ergonomic principles by reducing the need to rest the wrists, though preferences vary among players.

  • Nintendo Consoles: Gamecube, Wii, Switch, and Nintendo 64
