I continued working on my left hand gamepad.
I searched for better buttons, and found some which seemed to fit my needs:
While these were beeing shipped to me, I designed a case around the components:
I was pretty happy with the result, but that feeling ended when the buttons arrived.
These buttons were the right size but in order to hold press you have to press a metal ring inside the button against two contacts (obviously) while a metal spring tries to depress the button.
The tension is much too strong to continuesly hold it pressed. I tried other buttons but this primitive switch design is used everywhere.
With my design now finished but unuseable due to the shitty buttons, I loaded it up to various 3d Printing service sites to have an idea about the cost.
One case was around 85 euros, it was too much for just one draft so I decided to order a 3D Printer Kit from china for 180 euros instead.
The solution to the button problem were keyboard keys, they have a very soft press and are easily pressable for long durations.
I designed a case for an analog stick, keyboard keys and a psp style analog stick.
While the printer was beeing shipped I ordered another psp-analog stick from a different producer, the first one was unuseable, the values I got out of it were so imprecise that it defeated the purpose.
Next was printing the design, it tooks about 26 hours to print all components (not including revisions) the biggest print was the outer shell with 15 hours print time.
Next I assembled everything and tested the components:
So it turns out that the other psp-style analog sticks is utter shit too.
The values when centered are all over the place, depending where it was moved to beforehand, making it again unusable.
Maybe I received two duds, but I decided to not use a psp-style analog stick for my next version and use a normal analog stick instead.
Other things I learned from this draft is that having buttons for small finger and ring finger is useless because you have to be a piano player to be able to use all five fingers simultaneously, and because I wanted to have a button for each finger the case just got too large, making it uncomfortable to use.
For the next version I will change the psp-style stick for another normal thumbstick (isn’t really bigger and I can make an alternative stick end for ring finger use). Make the design smaller overall, and place the keys differently and include two more keys were it makes sense, also maybe leds.
