Cool Re: Powering a Larger Motor?

For all who say this is a dangerous project: I agree! In fact, my two friends and I had to sign a waiver before the school would even consider it! Obviously, safety is paramount.

To put all minds at ease, we WILL be using a killswitch in the case of signal loss (I am assuming the RC can recognize when it has lost the signal, in which case we will have the RC slam the brakes and release the gas line).

The FIRST team at my school has donated 2 victors, which was quite generous!

Regarding moving the car on the road and the legality of the project: we will never be driving the car anywhere but in open, grassy fields. The main site actually has about 10 acres of field with no obstructions. We will be transporting the car to school, but we will clearly not drive it there. We will be renting a trailer to put it on (luckily, my friend drives a beastly SUV).

Thanks for the suggestions about the brakes! That could come in useful! Hopefully it's not too complicated, because we only have about 14 days to complete this project!

Also, thanks to Andy A. for the point about the car battery, we will look into the issue of voltage continuity.

Construction begins this Sunday and ends on the 28th of May. I will keep the board updated on our progress and results, as there seems to be some genuine interest in the project. Part of our presentation is a video documentary about what we did, so hopefully I will be able to upload that on the internet for all to see. If not, I will certainly post pictures! Thanks, everyone!

ps. - To any programmers: how would one read a value from a joystick input? Right now, writing the code to manipulate the motors with the joystick is one of my chief concerns. Perhaps someone could simply point me in the direction of some sample code? Thanks!
