While we’re always happy to see accessibility aids come into fruition, most of them focus on daily tasks, not that there’s anything wrong with that. But what about having some fun? That’s the idea behind [Akaki Kuumeri]’s accessibly-awesome Joy-Con controller, the Squid-Con, which provides access to every button with just one hand. It even has tripod and AMPS mounts.
The joysticks themselves are controlled with the thumb and pinky, although some of [Akaki]’s beta testers changed it up a bit. That’s okay, because it’s designed to be comfortable in a variety of positions for either hand. As for the ABXY buttons, those are actuated using 3D-printed arms that connect to a central piece which [Akaki] calls the turbine.
But perhaps the coolest part of this project is the flexures that actuate the shoulder buttons (L, R, zL, and zR) on the controllers. It’s a series of four arms that are actuated by bringing the fingers back toward the palm. If all of this sounds confusing, just check out the video after the break.
We love flexures around here, and we’ve seen them in everything from cat feeding calendars to 6-DOF positioners to completely new kinds of joysticks.

Hackaday editors Mike Szczys and Elliot Williams march to the beat of the hardware hacking drum as they recount the greatest hacks to hit the ‘net this week. First up: Casio stepped in it with a spurious DMCA takedown notice. There’s a finite matrix of resistors that form a glorious clock now on display at CERN. Will a patio paver solve your 3D printer noise problems? And if you ever build with copper clad, you can’t miss this speedrun of priceless prototyping protips.
Take a look at the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!

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.
