17. Applications and Implications¶
What will it do?¶
This is a special device for digital artists working outdoors. This portable desk features an adjustable laptop holder, a built-in Space Mouse, and a programmable macro keyboard for a more comfortable work experience.
Who’s done what beforehand?¶
Before starting the research, I wanted to use an accelerometer for this purpose, but it turned out that this sensor would be awkward to use since it measures the angle of inclination relative to the ground, but I did not want that.
During my research I found several people who also made a space mouse. Space Mushroom : Full 6 DOFs Space Mouse by Shinsaku Hiura - for example, in this project 3 joysticks were used and the code used keyboard and mouse libraries. This option was also created for blender.
ORBION - Space Mouse Open Source by FaqTotum I also found this option with an encoder, LCD, joystick and LEDs and many other things. The author did a good job .
diy-spacemouse by Salim Benbouziyane. This author used a magnetometer for Spacemouse, but still used libraries using mouse and keyboard.
I liked all the options, but in my opinion it could have been done better. For example, I don’t want to use the mouse library because I want to be able to use the mouse separately at the same time when using Space Mouse.
What will you design?¶
In a global sense, my project includes several design stages.
-
1 is the static part, which includes the overall design.
-
2 aspect is the mechanical part, which includes the adjustable table itself and storage space. And also the mechanical part of the joysticks;
-
3 aspect is electronics; includes system integration, PCB design required for macro keyboard and backlight, and Spacemouse.
-
4 aspect is interface design. so that you can connect a computer to the device and program macros.
