  • How to build a $200 smart drone with the Pi Zero

    Erle Robotics, which I mentioned in last week's piece about the increasingly important role of Linux in robotics, supplies cheap components for DIY Raspberry Pi projects. I got in touch with the makers at Erle this week to come up with a great tutorial for our readers.

  • Add a battery pack to your Raspberry Pi

    Your Raspberry Pi’s mobility is usually restricted by the length of the power lead. Rather than limiting it to your desk or living room, however, you can use it for mobile projects as diverse as launching it into near-Earth orbit or monitoring and automating your garden.

    Of course, to do this you will need batteries, but adding battery power to your Raspberry Pi is simpler than you might have imagined. All that is required are six rechargeable AA batteries (or single-charge alkaline), a battery box with space for the batteries and a UBEC. The latter is a Universal Battery Elimination Circuit, a voltage regulator that will regulate the power supply and prevent damage to the Raspberry Pi, and can be bought for under £10.

  • Google’s New Home for All Things Open Source Runs Deep
    Google is not only one of the biggest contributors to the open source community but also has a strong track record of delivering open source tools and platforms that give birth to robust technology ecosystems. Just witness the momentum that Android and Kubernetes now have. Recently, Google launched a new home for its open source projects, processes, and initiatives. The site runs deep and has several avenues worth investigating. Here is a tour and some highlights worth noting.
  • Making your first open source contribution
  • Simplify expense reports with Smart Receipts
    The app is called Smart Receipts, it's licensed AGPL 3.0, and the source code is available on GitHub for Android and iOS.
  • How the TensorFlow team handles open source support
    Open-sourcing is more than throwing code over the wall and hoping somebody uses it. I knew this in theory, but being part of the TensorFlow team at Google has opened my eyes to how many different elements you need to build a community around a piece of software.
  • IRC for the 21st Century: Introducing Riot
    Internet relay chat (IRC) is one of the oldest chat protocols around and still popular in many open source communities. IRC's best strengths are as a decentralized and open communication method, making it easy for anyone to participate by running a network of their own. There are also a variety of clients and bots available for IRC.
