Topic: Powering Chumby from Roomba?
Hey everyone, I just bought a new Roomba and was thinking of making it into a Chumby controlled robot. I bought like 4 Insignia Infocast 3.5s last year on sale, and they're just waiting to be used!! I have been looking at the RooStick (http://www.sparkfun.com/products/670) which allows you to break out the battery Power from the roomba. I'm worried that the Chumby will draw too much power, however, as a comment there said that the device locks up if it goes over a certain amount. Preferably I'd like to keep the screen attached, but obviously that's going to pull more power, so if needed I could leave it off... I do also know that the Insignia has a few things broken out like the power, so presumably that's where I'd hook up the RooStick wires? Also, I wonder if the Chumby Hacker board for some reason has lower power requirements (it does, of course not come with the screen, but otherwise, it should be more or less the same, powerwise?). I really want to power the Chumby with the Roomba's battery because of the charging base feature - I don't want the chumby running off of some other battery pack that will die randomly while the Roomba is still in use. If this isn't at all feasible, are there other directions I can go in, like the BeagleBoard? I want to use a computer and not a microcontroller as I need easy access to USB devices and communication over WIFI.
