The update rate of my OLED screen via IC2 is to slow to do proper animation. Redrawing the eyes on a new position every 12 times a seconds was out of the question.

Luckily the oled-js library supports a scroll method. So I went with that and implement the movement of the eyes by controlling the scroll direction and timing the start-stop sequence with temporal. Because the entire screen buffer is pushed around by the hardware, the eyes don’t need to be so simplistic as I initially made them. They could as well be a bitmap with a set of mesmerising cat eyes, but for now this will do.

Dashboard and GitHub Repo

Felix is a NodeBot (http://nodebots.io). A NodeBot is a JavaScript powered robot. One of the benefits of using JavaScript and Node, is that it makes it trivial to create a  web based dashboard for your project. My dashboard has a simple joystick that controls Felix using Socket.io.

You can see a clip of Felix and the dashboard here:

The code is now on GitHub: https://github.com/Traverso/JSFelix
I will add the template files for the design to the repository as well.
