It’s another jam-packed issue of APC, this time the April 2014 issue and specifically, from me, you’ll find:
* a labs round-up of uninterruptible power supplies or UPSs – you might be able to, but I can’t remember the last UPS round-up I read, so it might be safe to say these don’t come around too often. If you’re looking for a way to gracefully power down your PC (or almost anything) during a storm or black-out, get one of these devices under your belt. I also explain how to choose one, what all the specs mean and how to avoid spending too much on stuff you don’t need.
* my Android Masterclass this month is on flashing a new kernel to your Android device. A new kernel is kinda-sorta half-way between flashing a new ROM and keeping your original stock ROM – it gives you some of the advantages found in custom ROMs but with most of the advantages of stock ROMs. I show you how it’s done, what to do and what not to do.
* And finally, in my Arduino Masterclass, I build a big-display Audio Spectrum Analyser. If you haven’t heard of Arduino, it’s the world’s favourite DIY hardware design platform, allowing you to design and build your own gadgets. This project uses local electronics brand Freetronic’s big 32×16-LED matrix display to display a stereo audio spectrum analyser using an Arduino Uno and a few easy-get cheap components. All the details plus where to get the software are available in this magazine.
That, plus buckets more in the April 2014 issue of APC, out now.
