Accessibilità is a family of open source hardware and software for wheel chairs! Starting with control interfaces first with the eventual goal of producing an entire open source electrical system someone can use to build a wheel chair or retrofit an existing one with a more modular, robust, and serviceable one.
First Two Projects:
Accessibilità BlackBox : The BlackBox is a device that works just as it sounds, it will be a custom board with a microntroller that has a USB interface on one side and on the other side a modular signal output interface that will allow the BlackBox to interface with any wheel chair or similar device. The BlackBox will be able to utilize a large array of USB devices and convert their control signal data into the kind for the Wheel chair. The BlackBox will be able to be configured via a software interface or re-flashing the firmware, so that any USB device can be calibrated to work.
Open Source Hall Effect Joy Stick: Thanks to intellectual property law almost all the electronics and joysticks involved with Wheel chairs/power chairs are unable to be serviced by users or technicians. Manufactures will sometimes make the user replace their entire Joystick or sometimes the entire wheel chair, this is madness and completely unsustainable, so I'm going to attempt to put a stop to it. My plan is to develop an open source hall effect based joy stick that can be 3D printed and assembled DIY, there will be open hardware PCBs and open source software to make it all work. This project is phase two in a series of many. the First is BlackBox which aims to be both a usable piece of tech and a research platform to help develop the Joystick and other accessible interfaces.
