  • RF Communication and the Internet of Things – Part 1

    Bill Marshall

    Last week another space odyssey came to a climax: the New Horizons probe shot past the now ‘dwarf’ planet, Pluto. By the standards of the Rosetta comet chaser or the various Mars rovers, it didn’t do very much, just took a lot of pictures, gathered some sensor data and continued on its way. Obviously the excitement for the mission scientists centres on the discovery that Pluto is not just a lifeless rock like our own moon. As an engineer, I am also interested in how the challenge of communicating with a spacecraft over 3 billion miles away was met. The design of such a ‘wireless’ link is not irrelevant to the Internet of Things developer back on Earth. In some ways, the problems for the space engineer are less complex, just a lot more expensive to solve, than those of the IoT product designer requiring a somewhat shorter wireless link.


    • Solar Energy Conversion using MIAC and Flowcode


      This work introduces an approach to the design of a boost converter for a photovoltaic (PV) system using the MIAC. The converter is designed to step up the variable voltage provided by a solar panel to a stable 24V, without any batteries. The output of the boost converter is monitored by the MIAC and used to adjust the duty cycle of a PWM control signal of the boost converter.


      • Arduino based PLC from Industrial Shields

        RS Components

        Industrial Shields manufactures open source industrial hardware to build machines, designs and installations in industrial automation and process control. Industrial Shields PLCs and Panel PCs are based on the most popular open source boards such as Arduino Leonardo, Arduino Mega, Raspberry Pi and Hummingboard; moreover, they support open source operative systems like Android and Linux.
