Leav I am currently in the US and if you want I will be able to stop at Radio Shack and pick some stuff up for you (small things like sensors and programming pack, not a kit).

Hi thanks David... but I wouldn't want to hassle you with all that... :) I have a friend who's coming over from the states soon, so i'm buying it all online and shipping to him... (hope he remembers to bring it...) :rolleyes:


My only real problem is the prototype programming kit. i sent them an e-mail and called but it was like 19:00 at texas when i called so they probably stopped working... :(

the whole VEX thing hinges on the prototype programming kit - i want to program like a big boy! :D

if anyonecould help me with that i would appreciate it...

thanks again!
-Leav

p.s.
the rotation sensor is for a lock picking robot (combination lock) which usualy have 60 points per rev. so i will need something that can find the angle accuratley time after time.

You can always gear up/down the VEX potentiometers to get the resolution you need. Typically it's the sampling rate (and the lack of quadrature) that limits the possibilities with the VEX pots... Sounds like a very interesting project.

Leav, you can use the official Vex Programming module and still program in real C (as in MPLAB). All you do is when you buy the Vex Programming Module you only install the USB-Serial driver, and ignore installing EasyC. The prototype and the official Vex modules are both the same price at $99 USD, so I'd just go with non-prototype one. :)

Re: Vex Vs. Edubot Vs. RCX Vs. NXT
 

This is entirely true. I've been playing with my vex kit since april and programming soleley in Mplab. Just use the same install cd that comes in the KOP at kickoff.

Also, Any pwm based sensor will work. Because vex has male inputs, you'll have to wire a short male to male pwm cable to use as an adapter for non vex sensors.

Although I would agree that Vex is the way to go; All Vex stuff is out of stock on Radio Shack's online store and is getting harder to find in local stores as well.

Re: Vex Vs. Edubot Vs. RCX Vs. NXT
 

I've found that a lot of the radioshacks (at least in my area) still have VEX products even if they're not displayed out front. Make sure you ask a person working there if they still have anything in stock. I went to three different ones today looking for the tank tread kit and none of them had it, but they all had the kits in stock.

Adding to what Art said, there's the default workspace that will open up in MpLab or your favorite source editor. Compile it with MCC18.

WVU (West Virginia University) uses those boards for education.... its called the Handy Board.

When they bought them at least the boards were very expensive but can't remember exactly how much he said they are. Nice thing about them is they have a pretty large LCD display and built in IR comm.
