Trackball mouse

thingiverse

This project enables the creation of a budget-friendly trackball mouse from a standard optical mouse. A trackball mouse empowers individuals with mobility issues in their hands or arms to control computers effectively. It is crucial for the trackball mouse's functionality that the laser beam emanating from the center of the mouse aligns perfectly (or is extremely close) to the ball. To reverse the mouse direction, you must download this software: http://hp.vector.co.jp/authors/VA026826/. Additionally, it is advisable to reduce the mouse speed. This project was conceived by the "Mutual de Seguridad C.Ch.C" from Chile. It was developed within a project led by the Direction of Innovation and Development in collaboration with the Neuro Rehabilitation Institute. Print Settings: Rafts: Yes Supports: Yes Resolution: 0.3mm Infill: 15 Notes: The resolution for all components except the ball is set at 0.3mm. For a smooth finish on the ball, it is recommended to print it with a resolution of 0.1mm and then sand it. Post-Printing: Assemble: 1. Remove the circuit from an optical mouse. 2. Connect wires to each pin of the right and left button switches. 3. Solder a flat switch at the end of the wires (one for each button). 4. Place the circuit inside the "Box Mouse" and secure it with silicone or melted PLA, as shown in the picture. 5. Attach the "Box Mouse" to the "Box Big". 6. Secure the "Switch Base" on the "Box Big" and attach the flat switch to it. 7. Position the printed Switch over the flat switch and secure the "Ball Base" where indicated in the picture. 8. Place the Ball on top. 9. Fix the "Box Top". 10. Optionally, you can apply an anti-slip coating to the bottom.
