  • Can 3D Printing Really Solve PPE Shortage in COVID-19 Crisis? The Myth, and The Facts!

    Amid COVID-19 crisis, we see severe shortage of Personal Protective Equipment (PPE) worldwide, to the point that a strict organization like FDA is making exceptions for PPE usage, and there are volunteer effors to try to alleviate this shortage like GetUsPPE. Also, Centers for Disease Control and Prevention (CDC) provides an Excel spreadsheet file to help calculate the PPE Burn Rate.

    There are many blog posts, video tutorials, and guides that teach people how to print their face shields and masks.

  • Raspberry Pi won’t let your watched pot boil
  • Growing fresh veggies with Rpi and Mender

    Some time ago my wife and I decided to teach our kids how to grow plants. We both have experience as we were raised in small towns where it was common to own a piece of land where you could plant home-grown fresh veggies.

    The upbringing of our kids is very different compared to ours, and we realized we never showed our kids how to grow our own veggies. We wanted them to learn and to understand that “the vegetables do not grow on the shop-shelf”, and that there is work (and fun) involved to grow those.

    The fact that we are gone for most of the summer and to start our own garden just to see it die when we returned seemed to be pointless. This was a challenge. Luckily, me being a hands-on engineer I promised my wife to take care of it. There were two options: we could buy something that will water our plants when we are gone, or I could do it myself (with a little help from our kids). Obviously I chose the more fun solution…

  • Comfile Launches 15-inch Industrial Raspberry Pi Touch Panel PC Powered by RPi CM3 Module

    Three years ago, we noted Comfile has made 7-inch and 10.2-inch touch panel PC’s powered by Raspberry Pi 3 Compute Module. The company has recently introduced a new model with a very similar design except for a larger 15-inch touchscreen display with 1024×768 resolution.

    ComfilePi CPi-A150WR 15-inch industrial Raspberry Pi touch panel PC still features the CM3 module, and the same ports including Ethernet, USB ports, RS232, RS485, and I2C interfaces accessible via terminal blocks, and a 40-pin I/O header.

Introducing Precursor

Precursor is a mobile, open source electronics platform. Similar to how a Raspberry Pi or an Arduino can be transformed into an IoT gadget with the addition of a couple breakout boards, some solder, and a bit of code, Precursor is a framework upon which you can assemble a wide variety of DIY mobile applications. Precursor is unique in the open source electronics space in that it’s designed from the ground-up to be carried around in your pocket. It’s not just a naked circuit board with connectors hanging off at random locations: it comes fully integrated—with a rechargeable battery, a display, and a keyboard—in a sleek, 7.2 mm (quarter-inch) aluminum case.
