Almost done

We are very close to finishing the latest revision of the rover. Because we needed to protect our shiny new motor controller, we did some math and came up with 300 watts of resistance between the battery and the controller so we don't draw more than it can handle. It was too expensive to buy 100 watt resistors, so we bought (24) 25 watt resistors instead. Quantity over quality. To mount them, rather than have a giant perfboard, I came up with the idea of making a cube. I finished this cube yesterday and it looks kinda cool. There is still a lot to do for this thing, and here is a quick list with some of the stuff we still need to work on:

-make sure resistor cube won't short
-mount resistor cube
-mount sabertooth
-hook everything up and plug it in
-make sure code supports all new hardware
-get vex servos working
-get router working to extend range of ad-hoc network
-full scale test with rocket
-write failsafe in case it goes out of range
-write kill switch
-write admin and user page to control it
-add sensors, get optical shaft encoder working (with javascript calc?)
-add connectors to make everything modular
-add headlights
-get wifi hopping working (wepbuster)

update website
design seperate admin and user pages for rover

Not all of this will get done this summer, but we are going to get as close as we can to completing this list. I PROMISE pictures and video are coming soon. For real.
