following up this post http://community.circuitbeard.co.uk/thread/anyone-used-tesselio/
I ordered a tessel2 from the website when it was finally available again (out of stock up through late january 2016)
Took a month or more to arrive. As did all the additional modules.
Also ordered their servo module. Supports multiple servos but for some reason they dont sell the same servo that comes in the module package separately. So you are forced to buy a different servo from another manufacturer.
Tessel 2 didn't work on Windows 10. Just got it working after back and forth on their forum a couple weeks ago (5 months sitting around unusable). I did try their steps which included multiple CLI tool installs. Got through all the steps until the last. Luckily they did come out with a final solution to flash the tessel 2 with new firmware that required fewer steps.
After successfully doing that I ran into another issue but resolved it by reinstalling the t2 client.
Finally it works! Followed steps to connect to wifi. Went smoothly. Now can run code on it without being tethered, that is cool.
Went to play with the wifi:
/* the wifi-cc3000 library is bundled in with Tessel's firmware, * so there's no need for an npm install. It's similar * to how require('tessel') works. */ var wifi = require('wifi-cc3000');
But when run I got an error message saying "cannot find module wifi-cc3000"
Went to the forum to report it and get some community help in case i am doing something wrong, but the forum has a 500 server error.
About me: I am a seasoned .net and front end web developer with little to no hardware experience. This was my experience and opinion. There are plenty of working complex project videos which tells me that others have had better luck. But I felt that I should share.
