Tobias and I were recently at a Microsoft IoT Hackathon in Berlin, where we were provided with some Tessels to hack on.
I’ve added a Crossbar.io application template that allows you to get started with Crossbar and the Tessel without any headaches. With an updated Crossbar (update from GitHub repo for now), just do
crossbar init --template hello:tessel
and you get the usual
hello app with one component running on the Tessel (and the other in the browser).
You can also take a look at the Alarm App that we created as part of the hackathon. This uses two Tessels, an accelerometer and a camera module, and has a NodeJS backend.
Hope this inspires others to give the Tessel a try - it’s a fun little device to tinker around with!
