I am building »End of semester« project and I was i need for small joystick. This is what I come on while searching instructables: http://www.instructables.com/id/Mini-Joystick-with-Fire-Button/
This design is pretty good, but angled push buttons are a bit expensive for me and I did have some spare non-angled push buttons. So I wanted to build the same mini joystick but with non-angled switches.
I came out with this idea, but it turned out to be not as good as I expected. So I have to make some last minute changes in design. Mechanical part is similar to the one in instructable mention earlier.
