Re: USB Hub Powering RPi

Mine is a 512 MB RAM version.
What about taking the power from the adapter that powers the hub (splitting it to power both RPi and the hub).

Re: USB Hub Powering RPi

I'm also interested in this. I have a 2.5A rated powered USB hub and was thinking of severing the data cables for powering the Pi so it doesn't recognise itself (would that happen at all?).

Re: Large numbers in C#

Oh, I think I get the general idea now. Thanks for the explanation, however, reading machine code is a bit out of my league.

Do you expect it to be exactly the same?

Re: Raspberry Pie?

Pretty much every summer my family and I go to a mountain that's nearby to scout for those little pinkish berries. We mostly make jam from them, but the prettiest are reserver for a cake.

Not a pie, but close.

Bon apetit.

Re: Solar car - A possibility

You're building a solar car?

Could you post some specs? I'm really interested.

As for your question, why not? If it's in a support car, there are no restrictions, but how do you plan to transfer the data from the solar car to the support car?
