Looking to See how many Propeller user are in my area.

I know there are a lot of Arduino users in my area, but I am looking to see how many Prop users there are.
I'm in Louisville Kentucky.
Mainly I looking for some programing assistance on some areas I am getting stuck on and thought I could pick some others brains and make some new
friends. Even willing to barter for some help.

We are all in your area. Just present your problems here and advice will come.

Well, OK, we can't do the "friends" part exactly, you know, hanging out sharing beers over barbecues and such.

I am a member of a local hacker Space (LVL1.ORG) and most members use the Arduino, and I started with the prop, and just try using it for my designs.
I have a program that has 4 temp sensors displaying in the Serial Terminal and want to be able display them with Video Out and or a LCD.
and just keep getting stuck on getting there.

Pick one or the other and post the type of display you want and you will get help. The more detail you provide on what equipment you have or want to use and what you want to do the better.

And build the project one piece at a time, with consideration to the overall goal.

Very often, customers bring us a big project where "nothing works" - it's just a matter of making each subsystem work, one at a time, learning as you go.

We have the best support on this forum, of any company. Nearly all of it is from our customers, too!

Click on the Explorer link in my sig and load that onto your Prop then connect a serial terminal at 115200 baud. On startup it will list various aspects of your hardware including a scan of your I2C devices and your 1-wire bus whichever ports pins they may be on. There is already support for some sensors built in and interfacing other devices is trivial. You can organise the display as a serial terminal which can be jazzed up a lot just by using ANSI colors and commands or you can use a variety of LCD displays as there are various "drivers" (copy and paste into terminal) available. Video normally requires too much memory although I plan to add a simple text mode to Tachyon (original version used 512x384 VGA graphics).

The good thing about the Explorer is that even though it is basically Tachyon Forth, it gets you up and going and interacting with your hardware in next to no time at all. There's even a game of life built into the current version that you can run on your serial terminal with widths of up to 512 cells!

Can you list the specific parts and code you're working with?

Right now I am using Four DS18b20 sensors
for now I would like to use the video out using a RCA Plug.
My skills are low in this department, that is why I am looking for local help, to
mentor me in my learning . But I will take all outside help I can get.
My end goal is to make a electronic dash board for my houseboat with cameras
watching my engines,
The dashboard will be a RCA monitor with gauge graphics for various sensors and
be able to switch to the engines cameras when the guages got out of limits.
i have been playing with it for about a year with no headway.

thanks for any input.

Generating video out (composite video - the yellow socket on many monitors/tvs) is easy. It requires 3 pins and 3 resistors (see the schematics of one of the prop dev boards on Parallax's store). But if you are happy with mono white on black background you can use my 1-pin video debugger. It just does text but it will give you a quick start.
There are other objects in the obex too for TV. Just load for a demo.

Be aware that the video needs to use a bank of 4 pins (ie P0-3, P4-7, P8-11, etc) but you will only use the first 3 pins for NTSC color. The fourth pin is only used for sending the signal by RF (radio broadcast short distance). IIRC the standard is to use P12-15 but it is easy enough to change. Try some of the color demos for starters, then ask questions here to help integrate into your project.
