Welcome. This is a spin-off from my other blog, blogbeebe. The idea came from my wife and kids, who suggested I create additional online diaries to better categorize my interests. This blog covers my interests in hobbyist robotics; the kind that mere mortals can afford. I have been a tinkerer in robotics since the early 80's. It was an offshoot in my interest in microprocessors and microcontrollers, such as the 6502 and 8048.

In this day and time I have the Lego Mindstorm's Robotic Invention Kit (and several add-ons of parts), several Vex Robotics kits, and all the odds and ends I've collected over the years. I've been investing in Vex since November of 2005 when I paid $300 for my first kit. I've been buying more this April because Radio Shack, the seller of Vex locally, have cut the price for just about everything in half. So now I've got sensors and rechargeable batteries and spare gears and wheels and tracks...

Another toy I have is a Gumstix and supporting boards. I purchased it about the same time I purchased my first Vex. I had the idea I'd use the Gumstix to drive controller on the Vex, but I've since discovered the Vex is a bit complicated by the fact that the protocol used to communicate with the Vex controller is undocumented. I put everything aside for a while, waiting for time to get back to it and dig out the details. Turns out that there's a new site name JVEX-robotics. It's purpose is to integrate a Java-based controller with the Vex system. I've just now started to dig into their system.

Finally, I'm waiting for Lego to release its latest robotics kit, Nxt. They started taking pre-orders April 1st, but I've held back because of the price of $250/kit. I'll probably place an order the first of May when my finances are clearer.

A Decade Long Religious Con Job

I rarely write inflammatory (what some might call trolling) titles to a post, but this building you see before you deserves it. I've been seeing this building next to I-4 just east of Altamonte/436 and Crane's Roost for nearly 12 years, and never knew who owned it. Today on a trip up to Lake Mary with my wife I saw it yet again. That's when I told her I wanted to stop by on the way back and poke around the property, and photograph any parts of it if I could.

What I discovered was this still unfinished eighteen story (I counted) white elephant, overgrown with weeds and yet still under slow-motion construction. It looks impressive with its exterior glass curtain walls, but that impression is quickly lost when you see the unfinished lower stories and look inside to the unfinished interior spaces.

A quick check via Google leads to an article written in 2010 by the Orlando Sentinel about the Majesty Tower. Based on what I read in the article it's owned by SuperChannel 55 WA…

Be Careful of Capital One Mailings

Capitol One ("What's in your wallet?") sent me a bit of deceptive snail mail today. I felt sure it was a credit card offer, and sure enough, it was. I open all credit card offers and shred them before putting them in the trash. Normally I just scan the front to make sure I don't miss anything; the Capital One offer made me stop for a moment and strike a bit of fear into my heart.

The letter's opening sentence read:
Our records as of December 30, 2009 indicate your Capital One Platinum MasterCard offer is currently valid and active.Not paying close attention during the first reading, I quickly developed this irrational worry that I was actually on the hook for something important, but I wasn't quite sure what. The letter listed "three ways to reply" at the bottom; via phone, the internet, and regular snail mail. I elected to call.

Once I reached the automated phone response system, the first entry offered was '1', to "activate my Capital …

cat-in-a-box channels greta garbo

So I'm sitting at my computer, when I start to notice a racket in back. I ignore it for a while until I hear a load "thump!", as if something had been dropped on the floor, followed by a lot of loud rattling. I turn around and see Lucy in the box just having a grand old time, rolling around and rattling that box a good one. I grab the GX1 and snap a few shots before she notices me and the camera, then leaps out and back into her chair (which used to be my chair before she decided it was her chair).

Just like caring for Katie my black Lab taught me about dogs, caring for Lucy is teaching me about cats. She finds me fascinating, as I do her. And she expresses great affection and love toward me without coaxing. I try to return the affection and love, but she is a cat, and she takes a bat at me on occasion, although I think that's just her being playful. She always has her claws in when she does that.

She sits next to me during the evening in her chair while I sit in mi…
