Arduino & Real-Time Clock

Mar 26, 2022
There are a lot of applications where knowing the right time is critical; logging sensor data, actions based on a time of day or making clocks or calendars. If you don't want to use a micro controller or computer that connects to the internet, then a real-time clock (RTC) is a must.

Arduino E-paper Screen
I like electronic paper, it appears more natural and less intrusive than other types of electronic display.

Moving from Blogger to Hugo
It’d be easy they said, move to a static site generator, up and running in no time at all. Well, “they” might have been right, but “they” hadn’t counted on my inability to leave anything not understood.

The BellRays and Discovering Music in 2002
"There's no accounting for taste" and "there's no justice" are unrevealing truisms, and something The BellRays almost certainly don't care about, but are probably as close to an explanation for the sad fact that they are not household names, as you're going to get.

So you've written yourself a flash new theme for your Hugo based website. Perhaps you even want to share it on the Official Theme Collection, but what's a simple way of creating a demo site for people to try out, and preferably for free? Luckily it's not too hard, but also not completely obvious.
