While Valve’s Steam Controller ultimately ended up being a commercial flop, most users agreed its use of touch-sensitive pads in place of traditional analog joysticks or digital directional buttons was at least a concept worth exploring. Those same touchpad aficionados will likely be very interested in this modification by [Matteo Pisani], which replaces the analog joystick on a Nintendo Switch Joy-Con with a capacitive touch sensor.
As [Matteo] explains in his detailed write-up, the initial inspiration for this project was to create a permanent solution to joystick fatigue and drifting issues. He reasoned that if he removed the physical joystick completely, there would be no way for it to fail in the future. We’re not sure how many people would have taken the concept this far, but you can’t argue with the logic.
The original joystick is a fairly straightforward device, comprised of two analog potentiometers and a digital button. It’s connected to the Joy-Con’s main PCB with a 0.5 mm pitch flexible cable, so the first step for [Matteo] was to spin up a breakout for the cable in KiCad to make the development process a bit easier.
The board design eventually evolved to hold an Arduino Pro Mini, a digital potentiometer, and a connector for the circular touchpad. The Arduino communicates with both devices over I2C, and translates the high resolution digital output of the touch controller into an analog signal within the expected ranges of the original joystick. [Matteo] says he still has to implement the stick’s digital push button, but thanks to an impressive 63 levels of pressure sensitivity on the pad, that shouldn’t be a problem.
Now that he knows the concept works, the next step for [Matteo] is to clean it up a bit. He’s already working on a much smaller PCB that should be able to fit inside the Joy-Con, and we’re very interested in seeing the final product.
We’ve seen several interesting Joy-Con hacks since the Switch hit the market, including a somewhat less intense joystick swap. Between the Joy-Con and the legendary Wii Remote, Nintendo certainly seems to have a knack for creating input devices that catch the imagination of gamers and tinkerers alike.

There are a lot of good reasons to think fondly of the Nintendo GameCube. Metroid Prime and Rogue Leader knocked it out of the park. The Game Boy Player was cool. There’s even something to be said for having a convenient carrying handle on a system designed for couch multiplayer. But if you ask anyone who played Nintendo’s sixth generation console what part they missed the least, it would probably be the controller. With all the visual flair of a Little Tikes playset and ergonomics designed for an octopus, it’s a controller that works well for first-party Nintendo titles and little else.
So it’s probably for the best that these Switch Joy-Cons created by [Madmorda] focus on recreating the aesthetics of the GameCube controller for Nintendo’s latest money-printing machine rather than its feel. With a surprising amount of work required to create them, these definitely count as a labor of love by someone who yearns for the days when gaming was more…cubic.
To start with, nobody makes Joy-Con cases in that signature GameCube purple so [Madmorda] had to paint them herself. The longevity of a painted controller is somewhat debatable, but the finish certainly looks fantastic right now.
For the left analog stick [Madmorda] was able to use the cap from a real GameCube controller, which fit perfectly. Apparently, Nintendo has been pretty happy with their analog stick sizing decisions for the last two decades or so. The right analog stick was another story, however, and she had to cut the shaft down to size with a Dremel to get the cap to fit.
Finally, molds were made of the original face buttons, which were then used to cast new buttons with colored resin to match the GameCube color scheme. Since the original Switch buttons don’t have indented lettering to get picked up by the mold, she had to laser etch them. This little detail goes a long way to selling the overall look.
The final result looks great, and compared to previous attempts we’ve seen to bring some of that early 2000’s Nintendo style to the Switch, this one is certainly less destructive. Check them out in action after the break!

Cardboard is one of the easiest ways to build something physical, far easier than the 3D printing and laser cutting we usually write about here. So when Nintendo released their Labo line of cardboard accessories, it doesn’t take a genius to predict the official product would be followed by a ton of user creations. Nintendo were smart enough to provide not only an internet forum for this creativity to gather, they also hold contests to highlight some of the best works.
The most impressive projects in the winner’s circle combined the one-of-a-kind cardboard creations with custom software written using Toy-Con Garage, the visual software development environment built into the Nintendo Switch console. Access to the garage is granted after a user runs through Nintendo Labo’s “Discover” activities, which walk the user behind the scenes of how their purchased Labo accessories work. This learning and discovery process thus also serves as an introductory programming tutorial, teaching its user how to create software to light up their custom cardboard creations.
It’s pretty cool that Nintendo opened up a bit of the mechanism behind Labo activities for users to create their own, but this is only a tiny subset of Nintendo Switch functionality. We have different hacks for different folks. Some of us enjoy reverse engineering details of how those little Joy-Cons work. Others hack up something to avoid a game puzzle that’s more frustrating than fun. And then there are those who are not satisfied until they have broken completely outside the sandbox.

[Christopher Foote] didn’t play quite as many games as he wanted to as a child. After years of catching up using the RetroPie and the PiGRRL 2, it was when he first picked up a Switch’s joy-cons that inspiration struck. Behold: the PiSwitch!
Realizing they operated on Bluetooth tech, [Foote] spent a fair chunk of time getting the joy-cons to properly pair to the Raspberry Pi 3 and function as one controller. Once done, he relied on Linux Joystick Mapper to manage the keybindings with some extra legwork besides to get the analog sticks working properly.
To make this console mobile, he’s packed a 6600mAh battery and Adafruit Powerboost 1000c into the device, added a second headphone jack and speaker for commuting and home enjoyment, and a Pi V2 camera module. A 3D printed case, encapsulating these components and a seven-inch touchscreen, also allows the joy-cons to be detached — though he plans on updating its design in the future.
The PiSwitch boots into a custom UI that lets you select different services — RetroPie, Kodi, Debian, and the terminal — while the joy-cons seamlessly function together or individually regardless of the activity. Check out the quick intro tour for this project after the break!

The Switch is Nintendo’s latest effort in the console world. One of its unique features is the Joy-Cons, a pair of controllers that can either attach directly to the console’s screen or be removed and used individually. But how do they work? [dekuNukem] decided to find out.
The reverse engineering efforts begin with disassembly. Surprisingly, there is no silkscreen present on the board to highlight test points or part numbers. This is likely
to conflate intended to stymie community efforts to work with the hardware, as different teams may create their own designations for components. Conversely, the chips inside still have their identifying markings present, which does ease identification somewhat.
There are some interesting choices made – the majority of the buttons are scanned in a matrix configuration by the on-board microcontroller, making it harder to spoof button presses. The controllers communicate over Bluetooth, switching to a physical serial connection when attached directly to the screen. This runs at a blistering 3,125,000 BPS after the initial handshake is completed.
Overall it’s a fairly comprehensive reverse engineering effort, and [dekuNukem] has provided excellent detail in the writeup for anyone else looking to get involved. There’s still some work left to do, like investigating the rumble messages, but it’s an excellent start and very comprehensive.
