Miss Ella Hunt (5yo SMA type-1) is a bit of a celebrity in her Indiana town–she’s on the news quite a bit, and even went to Washington to testify before the FDA fighting to get the first effective SMA drug (Spinraza) for everyone who needs it.
But for us, she’s just a kid who need to get mobile, and we’re delighted with the progress this week! Here’s Ella’s first attempt at using her power chair with just two switches. More information about links to our in-progress follows the video:
To create the adapter, we used an Adafruit Feather Bluefruit M0 to take two input switches, apply a bit of logic and timing control and then control three outputs via a Relay Board that we designed and built. We’ll make a full guide for this project, but we probably need a waiver of liability form for this one (Erica Hunt, Ella’s mom took ownership of the device before we used it, and was awesome).
Here’s some background if you want to follow the project:
And here’s the final product in Noe and Pedro Ruiz’s Feather Box (adapted to fit) and all wired up to the power chair:
To follow along on future project like this, please join our ATMakers Facebook Group! At this time, most of the discussion and design work still works there and only solutions that are completed are documented here on the main site. We’re working on improving that – if you’d like to help, please sign up on the home page and let us know!
This project is a great way to get those idle 3D Printers running and make something useful for AT Users in your community!
We’ve designed 3D Printed Switches that you can easily download and assemble. This guide will show you how! If you’re an AT User or part of an AT team (parent, SLP, ATP, etc.), bring this guide to your local STEM or Robotics team and they’ll know how to put it to good use.
Positioning switches is critical for folks with severe and profound physical challenges. Getting the AT Switch “just right” reduces fatigue, increases accuracy, and makes communication and environmental control much more successful.
This project uses 3D Printed adapters to add a standard 1/4″-20 (pronounced “Quarter-Twenty”) camera mount to common AT Switches. This is a great project for STEM programs that have an idle 3D Printer and need service hours and is a huge improvement for AT Switch users.
In this guide, we will show how to use inexpensive Bluetooth Keyboards and related devices to make iOS Switch Control interfaces. This video shows you how to do it and the guide blow shows everything you want to know!
First, and most importantly, this site has just had a major update & some extra protection added to try to stop the LOSERS who are trying to use our site to send SPAM and increase their own site’s SEO by taking advantage of folks with disabilities. Like I really have time for this crap. :-/
Second, we’ll be gathering at the AT Makers Facebook Group for an update concerning Closing the Gap and our efforts this summer!
Well, due to circumstances beyond our control, we’ve had to change our name. It’s OK, I wasn’t a big fan of OpenAT since it really implied that our goal was to make more Open Source hardware/software for AT users… when in reality that’s more of a tool, not a goal.
So, with some input from the community (thanks Yahnatan!), we’re now ATMakers.org!
I will update the name of the Facebook Group tomorrow and let the DNS propagation work its way through, but for now, this site will answer to both domains.
BTW, look for another guide in the next few days – I have some volunteers from a local HS Stem club coming to take pictures making the Wireless Switch Interface!
When you’re first starting out with electronics, it’s hard to know how to make good-looking, easy-to-understand diagrams of your ideas and creations. But doing so is a huge plus when others are trying to help you!
