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.

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.

Well another year of testing has come and gone so, it's time for an update! In short, I'm nearly there. This version is the last one with components mounted to a proto board. This is also the last dedicated version of the software.

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.

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.

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.

Now that you have your new drive tray and new servo arms in place, you need a controller and remote. You could use a commercial RC hobby controller that has the ability to mix mecanum wheels. However, depending on your goals, you might miss out on some expandable options that can really only be done with a microcontroller such as controlling screens (as in the Omnibot Eyes project - yet to come).

The Omnibot back in the day was a marvel but certainly had some interesting limitations. One item that they seemed to design as an after thought was the little round eyes. They were simple light bulbs that took a note from every other Spensor gift of the era - they flashed to the sounds that it made. Cool enough but hardly cutting edge even at that time.

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.

Omnibot Modernization
As a kid I dreamed of getting one of the Omnibots from RadioShack! Each Christmas and birthday I would beg and bargain for one but to no avail. They were too expensive for a toy, my parents would say. I dreamed of "programming" it to do all kinds of things little knowing that my parents were right. As cool as they were, Omnibots just weren't as useful as the advertising and my imagination made them.
Over the course of this series of builds for "version 1" I hope to turn my Omnibot into the bot I thought it was when I was a kid. I want to keep the original functionality but bring it into the modern era. So here's my punchlist:
- Moveable arms (motorized upgrade)
- Expressive "Eyes"
- Omnidirectional movement
- Status and time display
- Record movement with playback
- Record audio and playback
- Walkie-talkie function
- Full Featured remote control with motor and arm directional control, "eye" expression control, PTT, record movement mode select, and preset playback
