im in calgary alberta.. when you wrote CA, i thought maybe you thought i was in california..

its just starting to rain/snow right now. thats why i switched from big outdoor robots to making small indoor robots...

im not sure im happy with my battery choice for this bot. its a 730mAh 7.4V li-poly battery. my biggest issue is that its really not good to drain them past 2.5V/cell, so this pack can only go down to 5V. i may need to set up an ADC to measure battery voltage and have it shut down if it gets too low. and that gives me one more thing to worry about,.. i might remake the body so that its big enough to fit an alkaline 9V (its fibreglass and only took about 10 minutes to make). if i go to an alkaline, i cant charge it from a base station though, and nicads or nimh dont have much capacity.. alkalines are just ofver 500mAh at 9V, and the nicads are about 150-200 at 7.2V and nimh are about 300mAh at 7.2V....
