• Team 276linesofCode - Rails Girls Summer of Code 2017

    Tuesday, July 18, 2017

    Hey all,

    It has been a long long ride since February (when we had to write our applications for RGSoC 2017) and it’s finally July!

    This is when we start our Rails Girls Summer of Code (RGSoC) 2017 program, by working and contributing for Tessel. Having seen Tessel as a project in the RGSoC project list of 2017, we were eager to take it up at once since, we felt that through this project we would be able to discover both the horizons - Hardware and Software.

    Who are we?

    Team 276linesofCode

    Team 276linesofCode is an amalgamation of all things tech and electronic. The Team comprises Shravika Mittal and Brihi Joshi, a duo from New Delhi, India, in their sophomore year of College at IIIT Delhi. We are a dynamic duo that believes in learning and strengthening concepts while on the way to developing something.

    Shravika is an Undergraduate majoring in Computer Science and Engineering. It’s been hardly a year since she’s got her hands dirty with programming, and it’s already a vital part of her daily schedule. She brings out dedication and hard work in the team, excelling in whatever she does.

    Brihi is majoring in Electronics and Communication Engineering and loves to mix and fiddle with creativity in code. She brings in the caffeine-induced, late night coding sessions along with fresh experiments in the team.

    About our mentor - Kelsey

    Kelsey is the team’s mentor. She has been at Tessel since its beginning and is a member of the Tessel Project Steering Committee. All of the members of the Steering Committee are very excited to work with our RGSoC team– both to improve internal processes and mentoring capabilities, and to have the benefit of two full-time contributors building on Tessel!

    What is RGSoC?

    Rails Girls Summer of Code is a three month long award-winning global fellowship program aimed at bringing more diversity into Open Source.

    It is about helping introduce newcomers to the world of programming and further expand their knowledge and skills, by contributing to a worthwhile Open Source project. The focus is not on producing highly sophisticated code, but rather participants learning transferable skills from their project work. Apart from experience in large-scale projects, RGSoC also inculcates community building by introducing its scholars to people who maintain these projects and other members of the community involved in it.

    The RGSoC team structure goes like this : 1. The Students - A pair of Students who are enthusiastic to work on a chosen Open Source Project. 1. A Project Mentor - Usually an active contributor in the Open Source Project that is chosen. He/She is responsible for guiding the students in the project related tasks, features that are to be added and overall development of the project. 1. The Project Coaches - They are selected by the students during the time of the application and might be local (present in the same location as the students) or remote. They usually help the students in handling technical difficulties throughout the course of the program. 1. The Project Supervisor - They are the representatives of the RGSoC organisational team and guide the rest of the team with the procedures of the program.

    RGSoC has both the sides - technical as well as social. Apart from working on the project, we even need to get involved in social meets such as a team call with the project supervisor, maintaining daily logs about what was achieved and what challenges we encountered that day, writing blog posts about our experiences etc.

    This year, 20 teams were selected among which, 16 are Sponsored teams (We are one of them :smile:) and 4 are Volunteer teams.

    What are we here for?

    First and most important of all, to have fun! We are way too excited to start contributing and giving our best to this community.

    Before the program started, we went through the Tessel repositories, got our development boards and familiarised ourselves with JavaScript. Soon after the program began, we sent in a few PRs to understand the contribution protocol of Tessel.

    Soon as we complete the Tessel tutorials, we would be kicking off with an implementation of the 1-wire protocol in Tessel, which requires a lot of reading and working from our end. Then we are looking forward to move to a real world project, which can be solved using Tessel.

    Before the beginning of RGSoC 17, we had formulated a plan to work on a project called Humanoid Arm Project (HAP). We would like to continue our work on this and bring it into realisation for solving some day to day problems using technology.

    Having experienced a few IoT developmemt boards before, we cannot wait to delve deeper into the various functionalities and modules that Tessel has got to offer us. Also, Rust and JavaScript is a new experience for us. This would be the first time both of us are contributing to an Open Source project and we would like to learn the most we can from it.

    We really hope RGSoC would help us transition from Team 276linesofCode to Tesselators so that we can be a part of this community even after RGSoC is over.

    Here’s to an exciting summer! :tada: :confetti_ball:

  • This Week in Tessel: Fun with Open Source

    Tuesday, February 28, 2017

    Hi, Tesselators!

    Engineering work feels good. You work concretely toward a solution. You learn while you work. When you fix a bug or add a feature, you get a surge of accomplishment.

    Looking for something to sink your teeth into? In this issue of This Week in Tessel, we’ll give you suggestions for a few tasks to tackle.

    Here are some open Tessel issues you can dive into. Feel free to jump in and ask questions, even if it’s something new for you!

    What’s something I can finish in an evening?

    What’s something that will let me work with peers I can learn from?

    How do I claim an issue?

    If you see an issue you’d like to work on, comment that you’re working on it and ask for any information you need.

    Comment on the issue with any progress or problems– if you’ve tried something, even if you don’t resolve the issue, it might be useful for someone else who comes along later.

    Join us on Slack while you work so we can support you!

    Other stuff we’re up to

    • Want reimbursement for materials you need to work on Tessel? Conversely, want to financially support our work? Check out Tessel’s new Open Collective page

  • This Week in Tessel: Thanks for all the PRs

    Wednesday, November 23, 2016

    Hello, Tesselators!


    tessel.io is ready for a redesign

    The original design of tessel.io was focused on promoting and pre-ordering the Tessel 2, showing off its many features, modules, and example code. Now the Tessel 2 is out in the real world, available at SparkFun, Seeed Studio, and even Micro Center, so its time for tessel.io to focus on the Tessel Project and the incredible community around it. If you want to help design and build front page of an open-source hardware and software platform, check out the open issue and let us know how you want to get involved!

    Hacktoberfest Review

    Hacktoberfest was a rousing success yet again for the open-source community on GitHub. Thank you to the new and current contributors who participated because we appreciate every PR opened. There are still plenty of starter issues available for anyone who wants to get some practice in for next year’s event.

    Build cool stuff with SparkFun and Tessel 2

    Our friends at SparkFun and Bocoup put together some amazing project tutorials using parts from the Johnny-Five Inventor’s Kit, along with a few other materials. These projects are great for anyone who wants to move past the hardware basics and construct a full-featured machine or Internet-connected service with Tessel 2. If you haven’t bought the Inventor’s Kit yet, it will be a part of SparkFun’s Black Friday and Cyber Monday deals!

    Shoutout to the Tessel community

    That’s all for this week! Feel free to submit to the next newsletter. In the meantime, see you online.

    With love,
    Everyone at the Tessel Project

  • # This Week in Tessel: Hacktoberfest, Rust update, and conferences, oh my!

    Wednesday, October 26, 2016

    Hello, Tesselators



    DigitalOcean brought Hacktoberfest back to life this month to encourage more open source contributions by sharing resources for creating more approachable issues and giving out shirts & stickers to participants. Since one of our two core goals this year is to increase contributions and encourage both inclusion and accessibility to newcomers, we’ve labeled a bunch of issues for folks who want to contribute to open source and get involved with Tessel. These issues are also available after Hacktoberfest is over and available for anyone to work on.

    Local Rust Compilation

    As we iterate on the hardware and module APIs for Rust, we wanted to further improve the experience for Rust developers. Tim Ryan (@trimryan) has added support for local compilation of Rust programs in the latest release of t2-cli. You can now cross-compile Rust code for an embedded device seamlessly using t2 run. Check out the repo for instructions, try it out, and let us know how it’s working for you in the #rust-lang channel of our Slack community.

    Jon and Kelsey at JSConf Asia

    Jon McKay and Kelsey Breseman will be at JSConf Asia at the end of November to speak and host a workshop, where you can learn about hardware communication patterns and building a custom Tessel module. There is still plenty of time to grab a ticket and join them for a full 10 days of tech events!

    Cool stuff in the community:

  • This Week in Tessel: Special Report from Tesselcamp

    Monday, September 12, 2016

    Hello, Tesselators!

    Tessel Project leadership met up at Tesselcamp to determine the organization’s goals and main activities for the next year. In this special issue of This Week in Tessel, we’re reporting back to you:


    • We’ve set goals for the next year focusing on growing community and making it easier to use Tessel 2 in production. Read the specifics.
    • There are working groups to go with the goals, and we’d love to have you. Check them out here.
    • There are new releases out for T2 CLI (including Node 6 support) and Firmware. Plug in your Tessel and run npm i -g t2-cli; t2 update to use them.
    • Documentation now includes more of the stack.
    • Repos are now more contributor-friendly than ever with badges and standardized labels.

    Goals for the next year

    The two key goals for the next year are:

    1. Grow the community to increase contributions and encourage both inclusion and accessibility to newcomers.
      • Build effective working groups that can complete their tasks with measurable results.
      • Upgrade our documentation. Build more fritzing examples, API prototypes, and call out features that are currently missing from the docs.
      • Update the tessel.io website to more accurately represent the project and its plans.
    2. Support and grow the number of production deployments of Tessel in the field.
      • Research and create a guide for production-scale deployment of a Tessel project. Base this on the needs of current users.
      • Build Tessel Reach, the low-power hardware endpoints of a star network whose center is Tessel 2, so Tessel can make sense in more use cases.
      • Build first-class support for Rust API and documentation (parity with JS) and figure out JS-Rust inter-exection to provide for performant high-level coding of serious applications.
      • Investigate increasing RAM and Flash availability on Tessel or a revision of the Tessel board, reducing friction in production-level deployments.

    Read more in the Tessel Project readme.

    Working groups

    To accomplish the outlined goals, the team decided to form working groups as follows:

    • Learning WG: investigate user needs for production & write a guide on how to take a Tessel project to product scale. Also build and document GPIO/GUTS (Great Uses for Tessel in Stuff e.g. hacking a production system) projects. Learn more/get involved
    • Website WG: Create a better website for what we are & what we plan to be based on this year’s goals. Learn more/get involved
    • Rust WG: Get Rust to 1st class support
    • Reach WG: Ship Reach
    • Memory WG: Investigate strategies to make larger projects deployable on T2, possibly as a 2.1 Tessel hardware

    Since working groups are new for the project, we’re rolling out these groups slowly. The Learning and Website WG’s are our pilots. See the working groups section in the Tessel Project readme to learn more and get involved.

    Please get involved! It is our hope that working groups make it easier for people to engage with specific facets of the Tessel Project.

    Updates from the Repos

    Tesselcamp also included lots of work time. This helped us release new versions of T2 CLI, firmware, docs, and our repos!

    We recommend you update CLI and firmware with npm i -g t2-cli; t2 update so you get the benefits of our latest work.

    CLI Update

    • The node-usb module has been moved to the Tessel organization. Thanks to Kevin Mehall for being its lead developer and maintainer!
    • We’ve updated its CI infrastructure to publish binaries for macOS and Windows for all current Node versions.
    • As a result, we were also able to publish a new version of the T2 CLI. You no longer have to run Node 4.x to talk to Tessel from the command line; any Node version 4.x, 5.x, or 6.x is supported.

    Here are the full release notes for T2 CLI 0.0.27 and 0.0.28.

    Note: Tessel 2 still runs Node 4.x as it’s the current LTS (long-term support) version. The next LTS release is coming up in October, and we expect to release Node 6.x on Tessel at that time. You can follow our progress in upgrading Tessel 2 for Node 6.x support, and help us design a release process for supporting new Node versions going forward.

    Firmware Update

    The version 0.0.14 release of the Tessel firmware includes a variety of stability improvements for USB and GPIO communications.

    • This error should be long gone!
    • A few Network API bugs were squashed as well, making the returned network information more consistent.
    • The Tessel.Port.close method was added to allow closing power to individual ports, i.e. tessel.port.A.close() will turn off power to Port A. One or both ports can be opened again using tessel.open('A') or tessel.open(). More control over the power to the ports means more energy efficient projects!

    The full release notes can be found here.

    Docs Updates

    From the many recent updates to the Tessel docs, the most notable are:

    • The Debugging section now includes more documentation about Tessel 2’s full tech stack and how to interface with the Linux filesystem. This reflects the philosophy that you should be able to hack Tessel on any level, not just through the API we expose. It also helps blur the line between Tessel “users” and Tessel “contributors”.
    • The Tutorials section has new documentation on Pulse Width Modulation: what it is, how to use it, and diagrams for experimentation. We hope to do more in this space with other signal protocols in the future – please post an issue on the T2 Docs repo if there’s some electrical concept you’d particularly like to see more examples of.

    There is always more to do in documentation. Check out some of the well-outlined starter issues if you want to help the community learn!

    Contributor-friendly repo updates

    We try to make our repos as friendly as possible. A couple of new additions include:

    • We’ve added Code of Conduct badges to our active repos. This is an efficient way to explicitly link every repo to our Code of Conduct, and serves as a visual reminder to all visitors that we’re a caring community.
    • Standardized labels across our active repos make it easier to get work done. In addition to our contribution-starter label (where we take special care to point you in the direction of relevant documentation), there’s a design label for graphic design on some repos, and a discussion label for issues seeking advice and considered opinions.

    That’s all for this week!

    Usually, we’d have some links to projects and talks here, but we don’t want to wear you out with this email!

    Please feel free to submit talks, blog posts, projects, and more to the next newsletter. In the meantime, see you online.

    With love,
    Everyone at the Tessel Project
