Want a free board? Read below! My regular readers may already know that I never stop working on a project half-way. This is unfortunately the only exception so far, motivated by the fact that an IC isn’t doing what it’s supposed to do, that my thread on the TI support forum was left unanswered for […]

I’ve had this planned for a while. The concept is to display the frequency of the UK mains electricity supply. This is meant to be 50Hz, but the frequency actually fluctuates around this value, as a result of changes to supply and demand. If the frequency drops, it’s because demand has risen and/or supply has

This is a long delayed post. I am glad I finally finished making a video for it, and it’s time to introduce SquareWear 2.0 — an open-source, wearable Arduino microcontroller board. At heart, SqureWear 2.0 is an Arduino running at 3.3V and 12MHz. It has built-in mini-USB port for uploading programs, charging lithium batteries, and

The human-machine interface, once simply known as an “operator panel” or “terminal”, is changing rapidly, due to the graphical, visual way operators now interact with an industrial machine or process. At one time, designers of these systems could get by with a three-line segmented LCD display. Today, LCD interfaces are quickly replacing traditional LED and
