I went through all of the Github issues on all of our repos to identify those tasks that would be a good way to get started contributing to the Tessel ecosystem. The Task List can be found here. I've also added the 'help wanted' label to each of repos to call out those issues that we would love help on.
The tasks range from adding features to the Command Line Interface to improving our Node Compatibility to exposing functionality from our WiFi chip. We also have tasks on individual module drivers. If you'd like to help with the project and don't see a task you want to take on, respond to this thread and we'll work together to find a suitable project.
I'd also love feedback about how to make the contribution process smoother and more accessible for new or experienced hardware developers. The entire contribution guide can be found here.
