Omnibot Drive Base Modification

294120755_161746783038511_1985310016199997177_n

The factory drive for the Omnibot 5402 and Sr use two sets of wheels that are driven by two motors - one per side. This gives the Omnibot skid steering like a tank. It can turn in its own footprint and move forward and backward but not side to side (called strafing). For this project, I want to change out the original drive and wheels with 4 mecanum wheels each with its own drive motor. This will of course require new motor drivers since the original electronics aren't used.

Project S1.10 - Bed Headboard Control

20190124_234132

Sometimes buying cheap can be a blessing in disguise. In the case of our new memory foam bed base, if we hadn't decided to skimp, we may not have realized the joy of an intregrated bed in our smart home scheme.

Project S1.4 - Control panels

Person_looking_at_smartphone_in_the_dark_2

As I mentioned in UPDATED: My Home Automation Roadmap, I found that controlling lamps with remote switches is an easy and efficient method of bringing dumb lamps into the smart home fold. However, it introduces a new issue, I don't want to have to pull out my phone every time I want to turn one on or off. Imagine needing to get up in the middle of the night and having to find the phone in the dark, blinding yourself when you turn the screen on, finding the app and the lamp in the app and flipping it on ... all while trying to stay somewhat asleep. Enter, control panels.

UPDATED: My Home Automation Roadmap

vout4y2xurtt3l0vblbp

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.

Choosing a Home Automation Hub - How Hard Could it Be?

5684sm-Medium

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!

8 Months of Home Automation Lessons

hacp9-23-2018

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.

Robotic Arm Arduino Dev Platform

20180306_08534_20180311-045208_1

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.

Weather Station Project

Weather Station Project

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.

Robotic Arm Project V2

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.

Lapcade V1

Lapcade V1

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.

Robotic Arm Project

Robotic Arm Project

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.

Social & News Media Hiatus Experiment

nofbI'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?

New Project - Voice Controlled Home

Mr. IncredibleJay 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.
