GeekWorm Power Pack Hat Hack

Sorry for the tongue twister ūüėČ

I’ve been somewhat busy lately and it’s been a long time since my last post. I have a few projects on the go but not much time to sit down and write about them… Let’s see if this one goes through…

I’ve been lately looking for a reliable UPS system for Raspberry Pi 3. I moved my home server to a RPi a few months ago and even thou its behind an ACS UPS a couple of other projects involving RPis required mobility (one of them) and unassisted power backup (the other). So I started browsing several marketplaces looking for a solution.

Wordclock with Green Matrix effect

Clocks are¬†top projects for the maker community. There are tons of different ways to show or tell time. Or write time. Wordclocks are a subset of them by its own.

Recently I’ve been doing things with clocks and WS2812 LEDs (a.k.a. NeoPixels). My interest started with¬†Philippe Chr√©tien’s Fibonacci Clock campaign at Kickstarter. I thought: “Wow! That’s cool AND freaking freak! I want one”. But the $100 and the instructable he himself had done before about building your own made me decide to try it. Anyway, that’s a different story.

That project led to this one. Because suddenly I happened to have 9 spare¬†boards with an atmega328, an RTC, an SDCard slot, some nice buttons and the circuitry¬†to drive¬†a bunch of NeoPixels. I also happened to have a couple of LED matrices (you know, the kind of stuff you have in your bedroom drawer). So first I built a clone of the¬†The Game Frame Pixel Art Project. It was great and my kids loved the pixelart. But I’m not going to talk about that project either.
