The alice-like keyboard you are looking at.

Handwired Keyboard with Plasma-Cut Inox Frame and 3D Printed Split Plate

This handwired keyboard has a unique design with a plasma-cut inox frame and a 3D-printed split plate, reflecting the perfect combination of aesthetics and functionality. The keyboard boasts a sleek, modern design with a durable and aesthetically pleasing base. The sanded inox frame has a glossy finish, providing a distinct and premium look.

The 3D-printed split plate ensures precise switch positioning and eliminates any rattling during typing. Made from high-quality PETG, the plate is designed for durability. Brass inserts in the 3D-printed parts securely hold the screws in place.

Microcontroller

The keyboard is powered by an Arduino Pro Micro microcontroller, connected to each switch using a matrix scheme.

Switches

This keyboard uses Gateron Yellow Pro switches, known for their smooth linear feel, making them perfect for typing. Their high actuation force reduces accidental keypresses, ensuring precision.

Bill of Materials (BOM)

  • 1x Plasma-cut inox frame (also 3D printable)
  • 1x 3D-printed split plate
  • 1x Arduino Pro Micro (or ATMega 32u4 compatible microcontroller)
  • 67x Gateron Yellow Pro switch
  • 67x 1N4148 diode
  • 8x M3 screw
  • 8x M3x4mm brass insert

Layout and Matrix Scheme

The matrix configuration is peculiar yet functional, designed to facilitate assembly operations.

Future Improvements

Hand wiring can be messy, especially with 67 keys. The next version will include a PCB, which might also replace the 3D-printed plate to reduce assembly time. Additionally, an encoder could be added to the top right, relocating the tilde and delete keys one row below.

Conclusion

If you're looking for a high-quality, handwired keyboard that is both aesthetically pleasing and functional, this design is an excellent choice. With its unique design, premium materials, and exceptional switches, it offers a fantastic typing experience. The 3D-printed parts add customization options and ease of assembly, making it a rewarding DIY project.
