Trying to figure out serial lcd from sparkfun electronics on a picaxe board - 28 pin

Hello there, haven't asked too much on here lately but I was wondering if anyone could help me out on programming Serial LCD from sparkfun - http://www.robotshop.com/productinfo.aspx?pc=RB-Spa-330&lang=en-US- also found here- http://www.sparkfun.com/products/9393. This is for my 4th step or advancement on my start here robot.

Combat RC / ESC/BEC controllers and motors- Brushed and Brushless

Hey LMR I was hoping you could help me with a few questions the internet/google cannot fully teach me haha.

So I am thinking about maybe making a combat robot/battle bot (http://www.robotmarketplace.com/therobots.html) whatever you want to call it with some left over cash. So I have some questions on Brushless and Brushed motors.

What is the difference between Brushed and Brushless? So far I understand that one has three wires and the other two- +, - , brushless has a servo wire( to make it simple for me ;)    So what am I missing? Is one geared or what?

Future ideas- robots and paintball

Well I like to paintball with sum buddies and its getting bigger all the time so I have been involving robotics and electronics in paintball /airsoft.

So Im sorta running out of ideas that are worth using and cheap enough. 

For example-http://letsmakerobots.com/node/23474 i learned it was a little too expensive for me - a kid- to make and experiment.

Microphone programming on picaxe

Summer is here and I am trying to do as much programming with my robot as possible... so....

Ok I was looking for a forum or something on programming a microphone for picaxe so I can play it back on my speaker but found nothing. If anyone knows of a forum that has done this already please tell me! 

Ohterwise I want to hook up a microphone witch i believe i know how to do- http://www.rev-ed.co.uk/docs/picaxe_sound.pdf

but I do not know how to program it at all. So if anyone has more knowledge than me(which is a good possibility) then please tell me. 

Sharp programing on picaxe

Ok so I want a basic obstacle avoiding program with my sharp sensor. It is made on the start here robot. The programming language is picaxe basic. After hours of trying I still cant get it going correctly. So i hope u can help me. Thanks

The idea- It is supposed to read the distance and then decide whether it is far enough away to proceed forward or to go to sub program ahead (go backword, I know confusing haha sorry). So if you have any ideas please tell me. Better yet revise my program or make a new one and show me it. Thanks! First time with sharp.


LCD and picaxe

I am just beginning to research lcd boards. I have been told to get the 16 x 2 Alphanumeric LCD Module,  would this work, (sorry for font) http://www.robotshop.com/parallax-2x16-parallel-lcd.html  


Wireless camera plus lcd screen

Ever since I have seen the land warrior system ( http://dsc.discovery.com/videos/futureweapons-land-warrior.html ) I have been thrilled and wondered how hard it would be to make a simple version for airsoft or paintball.

I just thought I would put a camera on an airsoft gun, helmet, or  something and then it would relay it to a screen preferably on a 2.5 inch screen so it is on the eye and portable. 

I would like to know if the wireless camera could keep up with the movement of someone walking for a half way decent image.

My equipment would be -
