• This Week in Tessel – June 24, 2015

    Wednesday, June 24, 2015

    Welcome back, Tesselators! This Week in Tessel is where we highlight the latest news, projects, and events, from code, to community, to hardware manufacturing.

    Tessel in China

    The hardware team is in Shenzhen, getting ready to ramp up production. Follow the adventure live at #tessel2china.

    This week we’ll be on site as our manufacturer runs a 100 unit pre-production batch. After these units pass testing, we’ll begin the FCC & CE certification process before starting main production.

    Engineering Developments

    Itching to design some Tessel 2 projects? You’re in luck! Kelsey led the effort to release Tessel 2’s first hardware API docs, and Rick Waldron is in the review stages of creating a Tessel 2 Fritzing part, which will be out soon. Between that and the VM, you can basically build and test an entire Tessel 2 project before your boards arrive.


    Contribution party: Want to get involved in the Tessel project? We’re having an online contribution party tonight at 5:30pm PST. Join our chat (or come in person if you’re in the Bay Area) and we can help you get started.

    Upcoming talks: Flaki and Dan Callaghan from Mozilla will be delivering an awe-inspiring, demo-filled presentation about using Rust on IoT hardware (hint: it’s Tessel 2) and Firefox OS at the Open Tech School conference in Germany!


    The Auth0 team made HyperLock for physical authorization on a Tessel 1. The Realtime Framework, a Pub/Sub broker, released an SDK specifically for Tessel. Have you made something cool on Tessel? Post it to the projects page!

  • Welcoming Three New Team Members

    Wednesday, June 17, 2015

    This week we had three fantastic developers from three different countries join Tessel as the project’s first Team Members. We’re thrilled to have them on board not just to accelerate development of Tessel 2, but to provide the points of view and passion that make projects like Tessel thrive.


    From Hungary comes the renowned, Flaki (I don’t actually believe he has a surname). Flaki works at Mozilla and has a big supporter for both Rust and Tessel. It’s only natural that he will be contributing towards Rust tooling on Tessel 2!

    Kassandra Perch

    Kassandra Perch is a talented roboticist hailing from Texas. She is a very active member of both the Johnny-Five and Nodebots community so I’m super excited to see what JavaScript-powered robot overlords she builds with Tessel 2. Initially, she’s going to be helping us finish up the Tessel 2 CLI.

    Linus Unnebäck

    I only know that Linus writes excellent code and that he’s from Sweden (isn’t that the beauty of the internet?). Linus is one of the few developers who was able to understand the complexity that was the Tessel 1 Runtime and contribute to it. I’m excited to see how he contributes to the much more digestible Tessel 2 architecture.

    We’re all excited to have each of these excellent developers join the Tessel family and help us ship a powerful development board platform. Stay tuned for more updates!

    Thursday, June 11, 2015

    Welcome back, Tesselators! This Week in Tessel is where we highlight the latest news, projects, and events, from code, to community, to hardware manufacturing.

    New Team Members

    The Tessel Project team is growing! We want to welcome new team members Flaki, Matteo Collina, Kassandra Perch, Nick van de Walle, Linus Unnebäck, Evan Simpson, and Dave Nugent. As part of the team, they add and review contributions to the Tessel repos. Expect to see their introductions on the blog soon.

    Manufacturing Update

    Tessel 2 is ready for production! In exactly one week, Jia, Eric, and Kevin will be flying to China to oversee the manufacturing and testing of all 3000 new Tessel 2s. This begins with a pilot run of 100 boards and validating our testing process in person. Once we’re satisfied, the remaining Tessel 2s will be produced. Following that, the boards will undergo four or so weeks of FCC and CE certification. All told, we expect Tessel 2s to be shipped to customers in late August to early September.

    Developing for Tessel 2

    Tim has been focusing on developer tools, and this week released t2-compiler: a utility to compiling binary modules for Tessel 2. Check out the project for an example of how to use it today with the Tessel 2 VM. Also this week, Rick and Jon have been working together to build out a comprehensive test suite for the Tessel CLI.

    New Tessel Projects

    The folks at SynergyKit built a Tessel door that counts door opens and posts the activity to their backend. Milkcocoa: a pub/sub module for Tessel was demoed by Hirama Kiyohiko. Creating a DIY gesture sensor module was presented by Jia Huang and written up by Dave Nugent.

    Events and Conferences

    Learn about Tessel’s support for conference speakers and workshop leaders in Speaking at Conferences by Kelsey Breseman. Get inspired with Julian Cheal’s fantastic talk at JSConf Budapest in which he dances with drones among other things! Prefer the hackathon scene? Tessel is a prize in the upcoming TadHacks hackathon for Telecom Application Developers!

    This Week in Tessel is sent out every week, and we hope it plugs a joy and love module into your hearts. See you next time. — The Tessel Project Team

  • Tessel at Conferences

    Saturday, June 6, 2015

    6/8/15– Kelsey Breseman

    It’s conference season, and there are a lot of open calls for speakers! Consider presenting in the hardware/IoT space with Tessel– audiences are curious about the new field, and we’re here to support you.

    Why give a talk?

    Being a speaker is the most effective (and I think most enjoyable) way to experience a conference. You stand on a stage and talk about something you find interesting for just a few minutes. Then, for the rest of the conference, you’ll be approached by people who want to talk to you about that same interesting thing.

    As a speaker, you’re providing part of the conference’s value. Other speakers go to a conference to learn from each other, including you. You’ll likely get to know and talk to the people you went to the conference to see, because they came to see you as well.

    Organizers, particularly in the JS community, recognize the value you’re adding to the conference and work to make it easier for you. Speakers generally get free entry to the conference, and often airfare/lodging covered as well. If you’re interested in the conference, it’s definitely worth considering becoming a speaker.

    What can I talk about?

    Present whatever you’re excited about sharing! Have you made a cool project? Do you have ideas about the connected world? What insights do you have into open source projects and communities? I’ve given Tessel-related talks on human-computer interaction, the Node community, projects, and technical details of the project. It all depends on the audience and what you have to share.

    Or if you’re just excited about sharing the technology, many conferences offer workshop sessions and hackathons. This is my personal favorite “speaker” role– helping people build something in the physical world, often for the first time. If you’re interested in doing this, please reach out to me (kelsey at technical.io)! Since you likely don’t have 20 Tessels to run a workshop, we’re happy to lend you some.

    Get inspired by previous talks!

    First-time speakers: I’d like to offer you a note of particular encouragement. New faces, fresh perspectives, are particularly sought out by conference organizers. See the next section for Calls for Speakers.

    How can we help?

    We’re here to support you! Join us on Tessel’s community chat on Slack– we have an #events-speaking channel where you can come to ask questions or find someone to preview your talk. We also sometimes announce relevant conferences there, some of which are specifically asking for Tessel talks.

    You can also find a great number of calls for papers/calls for speakers on Lanyrd, a directory of conferences.

    When you’re building your slides, please feel free to borrow (with credit) from previous presentations! You can also find Tessel-related image assets on the press page. Videos of some past Tessel-related talks can be seen here.

    Leading up to your talk, please reach out! We are always excited to help promote your Tessel talk on Twitter and the forums. We’ll retweet photos from your presentation, and would love to share your slides as well– submit pull requests on the presentations repo!

    Get out there! And don’t hesitate to ask me for advice or talk suggestions– I’m @selkeymoonbeam on Twitter.

    Developing Tessel 2

    Latest Tessel boards from our manufacturer! We had fifteen new Tessel 2 boards come in this shipment. 13 of these worked out of the box, and the last two were brought online with a small amount of manufacturing rework and firmware tweaks. Left to test in this batch: evaluate that all 10-pin modules operate correctly on the new boards (finishing our API implementation in the process), as well as writing more comprehensive tests for our test rig. Barring any surprises, we’ll be able to witness our next manufacturing run of Tessels in China in person!


    Zac Colley made a new community module! Connect a thermal printer to Tessel using the tessel-thermalprinter module. Includes configuration for different typefaces and barcodes.

    A presentation of “Yodazone” by Anubhooti Pareek. Help relieve stress, powered by Tessel and PubNub.

    Communicate with LEGO TECHNIC Power Functions—LEGO motors, lights, and power source units)— with this Tessel module by Andrew Cashmore.

    Using the Tessel Camera module with the Project Oxford Face APIs, by Thomas Conté.


    The Time I Took my 6 Year Old to a Hackathon, by Tim Lytle.

    Remote Control and Monitoring for Tessel Servo, by PubNub HQ.

    Tessel around the world:

    SAP held a Tessel CodeJam in the Netherlands. Microsoft Azure held an IoT hackathon in Stockholm. Tessel was at WearHacks Paris, a wearables + IoT hackathon. Wouter Verweirder presented Node on hardware at Hookedfest in Belgium.

    In our next issue, we’ll have a progress update on our manufacturing timeline, as well as several new tools to get started developing for Tessel 2. Follow us on our blog, or on Twitter at @technicalhumans. Enjoy your week! — The Tessel Team
