I recently shipped out this modded ps4 controller for Johel, who has muscular dystrophy. Read the details here!
A woman contacted me, explaining that the latest version of the Playstation controller was almost unusable for her. The triggers were not working as she played in the top-down style, where you put your hands on top of the controller and use a surface to grip the triggers.
Initially I was going to design some kind of grip that glued onto the triggers. Then, I came up with this idea.
It isn’t perfect. It may not even solve her problem (ps4 triggers are at a different angle. not much I can do about that). however, it exists now and maybe it will help others.
This mat was printed with Ninjaflex on a Lulzbot Taz4 3D printer. This means it is a flexible rubber that grips the surface below pretty well. You could really use any soft rubber for this, I suspect that a rubber/gel insole might be perfect actually!
I have many requests for hardware modifications to Playstation controllers. Sadly, unless someone is asking for 3d printed extensions, I have to turn them down. This post will show why, and also offer a workaround.
When people request buttons to be moved (which is pretty common), I can usually say yes pretty easily. On an Xbox controller, there are nice solder pads to connect to. This is not the case inside a ps3 controller unfortunately.
All of the buttons, including the triggers are handled by this flexible material. I can not easily access the traces to make modifications here.
The flexible material is connected to the PCB by a pressure fitting that is actually part of the controller shell. This means that if I modify any of the pads, I risk the rest not fitting anymore. If I modify the shell, I risk the pressure not holding any more. It sucks.
Luckily, the thumbsticks are a standard format with nice big gooey solder blobs so I can do thumbstick mods.
The workaround: adapters
There are commercial adapters that let you use different controllers for different consoles. It isn’t the best solution, but any solution that lets someone play is the right solution.
HDE Cross Battle
$17 on Amazon
This allows you to use an Xbox360 controller on your Ps3. Unfortunately it does not appear to work with the ps4.
$59 on their site.
This little adapter does a TON. just see the graphic below. For more information, check out their website.
Using an Xbox 360 controller with one hand can be tricky, especially when you have to hold a trigger down for any extended period of time.
Here’s a super easy and super quick mod that will make your triggers “sticky”, meaning they won’t spring back to fully extended.
Note that you will have to glue something to your trigger to allow you to pull them back out.
Here’s a larger view of the assembly so you can see how it fits together.
