A broken PlayStation controller would normally be a bummer, and if the issue is losing calibration that’s stored in a non-documented format, you might as well bin it. For [Al] of [Al’s blog], however, it’s a challenge, turning into a four-part story – so far. The first installment was published January 1st this year, and seeing the pure enthusiasm [Al] has reverse-engineering the DualShock 4 controller, you might guess that this is a New Year’s gift from someone who knows [Al] very well. The list of problems with the joystick is numerous, to begin with – it’s easier to list all the things that work properly, and it isn’t many of them. Perhaps, the firmware problem is is the most interesting one to start with. Continue reading “Challenging A Broken DualShock 4 Controller To A Duel”

The Coolest Controller Mod, Hands Down
Video games are a great way to relax, and sometimes get your heart rate up at the same time. But unless you’re playing something like Dance Dance Revolution, the controls pretty much always require the use of both hands. Even the old Atari controller benefited from using the other hand for support.
But what if you don’t have the use of both hands? Or you have a repetitive stress injury? Or you just want to eat cheese curls with chopsticks while you play? [Akaki Kuumeri] has you covered with one of the hands-down greatest uses for 3D printing we’ve seen — a PlayStation DualShock 4 controller modified for one-handed use. If this looks familiar, it may be because [Akaki] made a PS5 controller version a while back, but who can get one of those, anyway?
Though [Akaki] does most of the demonstrating in the video below with their left hand, they were cool enough to make a right-handed version as well. In the left-handed version, the symbol buttons and right trigger are actuated with the left hand, and the right joystick is used by moving the whole controller against your leg, the table, the arm of the couch, or whatever you wish.
[Akaki] even designed some optional pieces, including a leg strap. The right-hand version of course does the D-pad instead. But what should the order of the arrow buttons be? After much contemplation, [Akaki] settled on the standard DDR configuration of ←↓↑→.
We love that the symbols are made from raw filament pressed into grooves, and think it’s totally awesome that this is made to be attached to the controller and removed with one hand. Check out the video below to see it in action with a handful of games.
Modifying A PS4 Dualshock4 Controller To Use A Mouse And Keyboard
[Mori] wanted to use his keyboard and mouse to play his favorite games on the PS4, so he decided to modify his Dualshock4 controller to feed it custom input signals.
In the heart of this build is an STM32F407 discovery board, which is connected to a USB hub. To perform this hack, [Mori] tore open the Dualshock4 controller to find the PCB traces coming from the sticks and buttons. He then used the STM32F407 and 2 Digital to Analog Converters (DACs) to create similar signals. Unfortunately for us, [Mori] only released the schematics but not the firmware. Our guess is that he had to configure the microcontroller as a USB host, enumerate the mouse/keyboard, parse the HID reports and feed the controller the corresponding inputs.
We embedded a video of the hack in action after the break. If you own a PS4, you may also want to see how to disable the Dualshock LEDs.
