Ok, this one is short and simple. Later Facebook and Twitter! So long and thanks for all the fish!

It's a funny thing - what you find when you start a project you think you know something about. If you're doing it right then you'll likely discover that you're not as slick as you thought you were. I suppose that is why I love these projects and goals so much. They make me stretch. On the flip-side, scope creep is real thing and not every project can be a voyage of discovery. So, this is my self-imposed roadmap for the first two phases of my overall home automation goals.

Internet of Things, Zigbee, Z-Wave, X10, MQTT, nodes, pairing! What is all of this? In this article, I'm going to go over the common language of home automation and try to help you make sense of all of these terms and concepts. *NOTE* this article is alive and will change as time goes by.

Since buying my printer early last year, I've had a lot of questions about it, like 'where to get one', 'how good is it compared to others' and 'what kind of prints can I get out of it'. What follows comes from numerous emails and private messages with folks over the last year and a half. This document will change as I find new useful info. 

As I mentioned in the introduction article of this series, there isn't a standard yet for smart home devices to talk to each other. However, the advertising and hype sure makes smart homes look like an easy care free way of life. Well, it isn't. If someone is telling you it is, beware! Snake oil will soon follow!

Since February of this year, I've been working on a lengthy project - I am slowly adding digital control and automation to the everyday things in our home. This project, unlike most of the others I've started grew out of a need rather than a want. Sure, the want is there and I'd be lying if I said that this wasn't one of the most fun projects I've committed to but, in this case, this project started with attempting to fill a need. Now that this project has matured a bit, I want to start chronicling my journey so that others with a similar need may find these experiments useful.

As I started brainstorming for version 2 of the arm, it became clear that I would need to make some changes so, I upgraded the electronics of my original robotic arm. This will allow me to create more modes of operation and create an I2C secondary interface.

It has been over a year and I feel like I have a decently tested version to post. It has been a learning experience to be sure and I am already working on some changes for the official version 1 of this monstrosity. In the meantime, here is My Backyard Weather, beta 1.

Let me make this clear, the 'Beginner' mentioned in this post isn't you, it's me! This weather beginner has built a prototype weather station and in the 2 months it has been up, I've learned a lot. I have learned that some of my ideas weren't so crazy and I learned that some of the things I took for granted were way off base. 

So, call this a beta, a prototype version or whatever you like, just don't call it finished. Here I present to you my lessons learned on the way to stable state.

Overview

I've always wanted to build a weather station. I have an interest in weather science but, for me a weather station is all of the stuff I like about electronics - real world use of remote sensing that can be used for practical stuff. From home automation to gardening to knowing what's in the air, local weather and environmental sensing can be used to make subtle cumulative changes that add up to better health and lower bills.

Overview

I am working on an upgrade of my Robotic Arm Project that has managed to survive two years worth of kid interactions over the course of many different events. To say I am surprised at its longevity is an understatement.

I'm not much of a gamer. When I was a kid, I had a space invaders handheld game, a Coleco Telstar Colortron, and a Tandy Color Computer 2. Although the COCO2 had program cartridges, most of the games I played on it were typed in from a game code book my parents gave me with the computer. That may sound like I must have been motivated to play the games (to spend all that time typing them in) but in reality, I was more interested in seeing how they worked than I was in playing them. 

For years, politicians promised much but delivered little and people became more and more disillusioned and disenfranchised. In response, new politicians seized on this growing public anger and not only promised to fix it but also promised to undo and prevent "the other side" from doing anything else. Thus, we see the erosion of cooperation and consensus building.

After several months on the to-do list, I finally cleaned up the Robotic Arm Project code a bit to improve my robotic arm's functionality and performance.

A few months ago a fellow member of MTRAS posted on our Facebook page a link to a robotic arm project. The article poster / builder used a design that was previously posted as open source to Thingiverse.com. I took a look and thought that it would make a fun project that would be simple enough to follow but also challenging enough to be rewarding. So I decided to give it a shot.

I've been noticing that I spend a lot of time online. I don't have a lot of social media accounts to manage but nonetheless I've been feeling like the time I've spent wasn't worth much. Sure, I've started some discussions on topics I think are important and I've learned a lot from other's point of view, but what has the net balance to all of this online perusing been? Did I really gain anything or add to the world in any meaningful way?

Jay Napier is Mr. IncredibleIt is so easy to take everything for granted. Let's take for example, turning on the TV. Next to none of us give this simple task a second thought. I have had days when I came home from work so distracted that, after a few minutes of scurrying around the house, wondered if it was actually me that turned on the TV.

When you enter a room, do you make much of a mental exercise out of turning on the light? I don't. It is like breathing, I just do it. What about turning on a fan or changing the thermostat if you're too hot or cold. All of this is pretty simple stuff and most of us don't give it a second thought - that is, until you can't do it anymore.

It is amazing how easy it is to get sidetracked on a goal or project. Sometimes the cause is small, for example needing to run an errand during your normal workout time. Then the next day rolls around and the "need" to run more errands in that same stretch of time becomes easier to justify. Finally, that time somehow switched from workout time to errand time.

Other times there are legitimate, longer period interruptions such as illness, changes at work, or other lifestyle changes that alter the way you spend your time either for long periods or permanently. Not much can be done about these events except how we decide to RE-prioritize around them.

What is all of this?!?

Every few years I reevaluate the big picture. Yes, "what does it all mean?" is in that list but generally this is more of a state of the union style overview. I begin with questions such as "How is my life progressing?", "Do I still believe X or Y in the same way I once did?", and "Why am I doing X?" and somewhere along the way, life changes course a bit to account for the lessons learned or to challenge assumptions made.
