what about firewire?Purple-Days said:Alex, the Purple-Days requires 12 Volts @1000mA. A USB power pin is 5 Volts. Won't work.
Which transformers do you use btw are they AC or DC ? Which does it ship with ?Purple-Days said:Alex, the Purple-Days requires 12 Volts @1000mA. A USB power pin is 5 Volts. Won't work.

I hadn't considered firewire as an option, I don't know about the technical specs for that port, but it isn't as common as USB, although my laptop does have a firewire port.
Tom, I know you said you don't think powering the PD off USB will work, however you might find the following page of interest.
http://www.dd-wrt.com/wiki/index.php/LaFonera_Hardware_Power_from_USB
obviously you can ignore what the poster is talking about regarding the router,
however, in one section he is talking about what to do if someone needs more power, and describes some kind of double headed USB cable,
and he states.
"Confirmed. The two head USB cable (typically for external 2.5" hard drives) will work to power a device that is rated as 12 volts, 1000ma."
what do you think? It makes sense to me given that each USB port can supply up to 500 MA, though I am not precisely sure how the writer was able to get from 5 to 12 volts for the ports.
Anyway, I just post this up as food for thought, any comments welcome.

surely, it depends a lot on the capacity of the cells in the battery.
also, you can get laptops with very long lasting batteries these days, up to 9 hours or so I believe now, though my battery only lasts between 6 and 8. I remember the old days though when you were lucky if you got about 3 hours from a laptop.
Also, remember you could extend the runtime of the pd off a laptop battery, by turning off a lot of the functions on the laptop, for example hard discs, monitor, webcam, wireless card, bluetooth, and lots of programs on the laptop to reduce memory and processor useage.
I am sure there are a lot of other things that could be switched off on the average laptop.
after all, its up to people weather they just want to power the pd off the laptop or want to try to work at the same time.

Well there's always this strategy if you're not worried about ruining the environment and keeping a low profile
