Inspiration
When you bike in traffic (human or cars) it's really important to use turn signals so the traffic around you can react safely. In theory, you can do this with hand signals, but in practice many drivers and pedestrians either don't understand hand signals or can't see them.
What it does
The Myo Signal is a rear light add on that gives vehicles turn signals. More importantly, these turn signals are gesture controlled, so the turn signal activation is just an extension of the user's natural movements.
How I built it
The heart of the hack is the Intel Galileo as it is a system that not only has low level IO, but also has a full stack and supports connectivity with bluetooth and wifi. I added a Myo gesture control unit, which is connected directly to the board through bluetooth, for the gesture control UI, and then used the Adruino breakout for the Galileo to drive the LED power electronics for the light units.
Challenges I ran into
There are no good Galileo Bluetooth LE libraries and also the only stable Myo library for Linux has very minimal functionality.
Accomplishments that I'm proud of
The fact that this hack really encompasses the full stack of computation in our lives, from high level UI, to good old fashioned circuitry. Also, this was my first hackathon, so I'm proud I was able to make something at all.
What I learned
What's next for Myo Signal
The two big things are adding IMU support for the linux drivers so more hand movements can be supported, and using more power efficient components so the device can be powered by battery and be installed onto vehicles.
