If we add together parts of parallax propeller .spin ping and radar. What do we get? Spingdar!

I recently finished a course in .net C# (.cs) at Spokane Community College. So over the spring break, which ends today, I reviewed pingdar from Parallax http://forums.parallax.com/forums/default.aspx?f=6&m=129099 What my programs do is effectively the same however I display the data on a pc using GDI+ in C# on a radar like circular graphics object on a form with a sweeping line and a dot for the location plot. The math is done in the .cs rather than the propeller. I wanted to begin learning about the xbee radios so I utilized them to connect my Stingray with Lynxmotion tilt pan servo assembly to the pc. That’s my dog Sampson under the workbench. He’s my best bud. Above the ping sensor is a TTL micro cam from 4dsystems. I haven’t begun to work on that yet. It’s just sitting in where I think I would like to mount it.

Now about this project and the source code. I had a goal to accomplish a certain amount of functionality. At this point it was just for the learning. I accomplished that goal. The code is not pretty and the entire project isn’t of much use except as a learning experience so keep that in mind if you download the source.

When I have time again this summer I’d like to move on to a phase two of this learning project and enhance the graphics and add probably some code as delegate in .cs. All the graphics and the input data manipulation occur in a serial received data event.

Very useful program and informative for general .cs programming techniques and specifically for serial communications in C# http://msmvps.com/blogs/coad/archive/2005/03/23/39466.aspx

Facebook Boobs

February 6, 2010


I guess I’m just a facebook boob caught up by chests inflated

I clicked a box marked single after entering my birth day

As if by magic forces there a farce did then erupt

The chests of girls depicted in advertisements did grow

I have two brains that you might know, one above and one below

I call this Richard Cranium and Dick the one below.

My life involves the discipline and confusion of their lies

As I strive to understand a balance allowing members to elucidate or grow

as Dick digresses forward growing Richard that more dimmer. I hope to find a facebook boob whose

chest might fit my zipper. Damn it, knock it off Dick. Umm sorry about that…

double entendre and innuendo are a tangent for later intercourse <doh!>

Facebook boobs grew bigger as their tales grew tails so wicked that I felt obliged to dicker

OK I gota get a hold of myself cum on this is serious! Doh! See what I mean about my Richard growing dimmer?

With a paypal nudge down under from Dick Zipper while Richard shuddered Dick believed the proclamation from the statuesque post statutory blonde: “I’m looking for older men”

Now I offer this pledge reviewed in these words telling.

I will not succumb to facebook boobs. I will retain Richard upon my shoulders while allowing Dick his place. I detest the commercial exploitation of the differences of our genders. I enjoy the femininity of a woman’s grace while demand for she and me that we take our place together as equals not apart. Sharing life’s living of daily triumphs and tragedies respecting space while sharing space I hope to find myself in a space in space not spaced with space in place. What I mean to say is that something worth having can not be pursued. But I wouldn’t mind if in this time, without a line I might find something so sublime. Just a prime time for a two of us to become as one in time. Now if it’s not my time for this, I know that I have won some time by writing this and sharing it this time. Thanks for listening.
