Hi everyone!
Well, I'm new to the propeller world. Actually, I'm still waiting for it to be shipped. I have it from a reliable source (hi ken!) that it will be shipped tomarrow (Monday the 5th). I have a BS2 (no letters after) on a BOE-bot, but imnow upgrading to top of the line! I'm getting two of the actual chips, a RFID tag demo kit, the transponder set, a few ping)))s, and some assorted other junk. I think I'm also getting an accelerometer. I have a few ideas for projects:
•Make it communicate with a BOE-bot with the wireless transmitter, and drive the BOE-bot around
•Put it in my easy star (a type of big slow RC plane) and have it fly
•Put it in a 1984 Light Blue Toyota Tercel (the BEST CAR EVER) and make it control throttle for me
Obviously, none of these are my first project. I'm just going to try to get prop to prop communication first.

Have fun with the prop. I'd recommend you get aquinted with the development tools and with the different debuggers around and with our great propeller wiki @ propeller.wikispaces.org.
have fun! I know you will [noparse]:)[/noparse]

Welcome aboard... you will never be bored again... and you will never make a better choice.
If you are looking for a really fun project that has lots of uses... look into using infra-red to drive your bot around... not the most general or common solution... but as a way of getting into the prop and getting something working right out of the box with some really great objects and tutorials you can't beat the infra-red stuff. It is fun and very instructive...and you can use either a TV remote or generate the signals with a Prop.
The accelerometer is spectacular... but you have to temperature compensate it to get reliable results in the direct measurements and in the first derivatives.
I personally think that the accelerometer is so sensitive to temperature that it could be used as a very good thermometer...but I haven't actually proved the point... maybe you will[noparse]:)[/noparse]
You would think that the Ping is a no-brainer... it isn't. Leave that go until you have some good experience with your Prop.
You didn't mention GPS... that means that you are more interested in having your car go fast than knowing exactly where it is... this indicates that you are probably too young to have driving children... you are one lucky rubrchicken... enjoy, enjoy, enjoy.

@everyone I don't really know spin yet, I have learned a little of:java, c++, perl, pbasic, logo :-(, and some web stuff (which doesn't count) I've been reading my way through the 438 pages of manual that come with the prop, I'm not very far into programming it yet.
Glad you made it here.

Trust me, you will learn Spin just by looking at the objects that support your devices...
PASM... propeller assembly is not so simple and is really worthy of serious study...
GPS is really easy... you just need to know how to hook it up and where to look for the right object...the last time I looked the most useful object wasn't in the OBEX. One thing I really like is that the GPS is practically impossible to destroy.
About the accelerometer... I got busy on other things and never actually got to the point of temperature compensating the data...One potential problem that worried me is that you actually need to compensate for the temperature of the accelerometer ... which might be related to the surrounding temperature in a nice way and might not be... so you might actually need to hook up a heat sink to the chip and measure the temperature of that using a thermocouple... I don't really know... it is just what I was thinking when I moved on to another project... but I am still very interested.
When you get everything hooked up and the software working, you need to plot your temperature readings vs the accelerometer readings when nothing is moving... If you get a straight line or a smooth curve, then you have a reliable accelerometer set up, which will be good enough for your car... you will also have a gravity driven thermometer!!!
You might want to make note of the barometric pressure too... if it is sensitive to temperature then it might be slightly sensitive to the barometric pressure too!!!
Be thorough...look at various rates of change in the room temperature... make a whole bunch of different plots and if they all give you the same straight or curved line... you are in business. If not... then you need to glue your thermometer to your accelerometer... or attach a thermocouple and possibly a heat sink. You will need to reconfirm your understanding when you get your entire circuit built... because the currents traveling around and through your accelerometer might change, depending upon what else you hook up and how you are powering everything...
Please let us know how you are doing.

To all, thanks for supporting our latest member, RubrChicken. This is all new for him as he noted, but he'll put our efforts to good use and and help us restore confidence in America's text-messaging, video-gaming youth. He's too young to drive the family Tercel, but he's got the ability and support to turn it into a robo-car. Considering the peer pressure from his Arduino-pushing friends I felt it was very appropriate to introduce him to the Propeller.

@rjo_ Ill hook up my 1620 (or something) and the accelerometer to the same block of copper and get temperature readings as I don't move anything.
And apparently I'll have to wait another day... It's like torture!
