Custom Keyboard Integrating SpaceMouse Gains Popularity Among 3D Designers
A novel blend of ergonomic keyboards and advanced input systems is gaining traction in the DIY community, as 3D designers and engineers opt for custom-built keyboards incorporating a SpaceMouse device. A SpaceMouse, a specialized 6-degrees-of-freedom (6DoF) input controller, offers unique spatial navigation capabilities that can potentially enhance workflows for 3D design and CAD tasks.
Building a hybrid "mouse-cropad" or similar device by integrating a SpaceMouse into a custom keyboard can serve as an optimal setup for professionals engaging in 3D modeling or engineering work. DIY projects involving SpaceMouse integration are rare but show promise for streamlining workflows by placing the device's intuitive spatial navigation features at users' fingertip.
Here's a step-by-step guide for those interested in building their own SpaceMouse-integrated keyboard:
1. Collect Your Components
- SpaceMouse Device: Commercial units (such as 3Dconnexion) or DIY versions based on open-source or hackable models can be used.
- Custom Keyboard PCB/Plate: Choose an open-source keyboard PCB design or create your own.
- Switches and Keycaps: Ergonomic switches are recommended for comfort.
- 3D Printing or CNC Services: For casing the keyboard and SpaceMouse components.
- Microcontroller: Compatible microcontrollers include Pro Micro, RP2040, or other MCUs that support QMK/Vial firmware.
- Wiring and Soldering Tools
2. Plan Your Layout
- SpaceMouse Integration: Place the SpaceMouse centrally or near the thumb cluster for easy access.
- Ergonomic Design: Consider comfort while typing and using the SpaceMouse.
- Custom Key Mapping: Assign dedicated macro keys or layers for SpaceMouse functions.
3. Assemble the Keyboard Structure
- Case Design: Use CAD software to create a case that accommodates both the keyboard and SpaceMouse components.
- Mounting: Securely place the SpaceMouse and keyboard PCB inside the case.
4. Connect and Program
- SpaceMouse Connectivity: Connect the SpaceMouse via USB or wire it directly to the microcontroller.
- Keyboard Firmware: Use QMK or Vial firmware to customize key mapping and macros.
- Optional: Advanced Integration: For advanced users, hack a DIY SpaceMouse using Hall effect or optical sensors, then wire it into the keyboard’s microcontroller for a fully integrated device.
5. Assemble and Test
- Final Assembly: Assemble the case, switches, keycaps, and SpaceMouse.
- Testing: Ensure all buttons and SpaceMouse features work correctly.
- Firmware Adjustments: Fine-tune the firmware for optimal functionality.
A renowned example of a successful SpaceMouse-integrated keyboard is the Keebin' With Kristina project on Hackaday, which features ideas for hybrid input devices such as keyboards with built-in trackballs. Additionally, open-source SpaceMouse projects using custom PCBs with Hall effect or optical sensors could serve as a basis for direct integration into a keyboard case.
Tips for applying an ergonomic design include positioning the SpaceMouse for comfortable, one-handed use while typing and utilizing QMK/Vial firmware for custom mappings and macros. Rapid prototyping via 3D printing makes it possible to fine-tune the case design for a snug fit of both components.
By combining ergonomic keyboard design with the unique input capabilities provided by a SpaceMouse, users can create a productivity-enhancing, one-of-a-kind keyboard setup tailored for their 3D modeling and CAD work.
A SpaceMouse-integrated custom keyboard, combining elements of gadgets and technology, can serve as an optimal setup for professionals involved in 3D modeling or engineering work. DIY projects integrating a SpaceMouse into a custom keyboard can potentially streamline workflows by placing the device's spatial navigation features at users' fingertips.
