AT Hand Raiser using Adafruit Trinket M0

This great little project was inspired by Michelle Brosse in the Facebook Group: she was heading to college and couldn’t get the professor’s attention.  She wasn’t looking for a panic button or the like, just a way to raise her hand.  This device does exactly that!

Check out the full guide at the Adafruit Learning System: CircuitPython Powered AT Hand-Raiser

There, you’ll find full instructions, downloadable code and the STL files needed to print the parts.  We even included assembly instructions in video form.

To read the original request, here’s a link to the post in the Facebook Group.  Make sure to join us there for more great AT ideas and solutions!

CircuitPython Creates New AT Opportunities

For those of you who don’t know, CircuitPython is a programming language and environment for small computers and microcontrollers that is sponsored by our friends at Adafruit.

It is a variant of Python, and a fork of the popular MicroPython that’s been out for a few years.  However, CircuitPython has a few differences that are really helpful for Assistive Technology., and we’re going to use it to amazing things!

Automated Testing of 3.5mm AT Jacks

At ATMakers, we use lots of AT Jacks.  Every switch-adapted toy, every interface device, almost everything we make requires a 3.5mm jack or plug.

Because of this, we ask STEM programs and Robotics teams to make us jacks and plugs as their first soldering project, and we’re always making them here.  Therefore we have lots of jacks, and we need to do lots of testing! This project makes that simple!

Stereo-jack with Mono Configuration

These jacks are used on many toy adaptations to enable them to work with switches.  We use a mono-jack configuration on stereo jacks so that we can make every switch (mono or stereo) work.  This is done by shorting the the female end stereo jack ring and sleeve connectors.  This post shows two female jack styles we have used on toy adaptations.
