Re: USB Hub Powering RPi

Thanks, I have a feeling it is possible because it would be rather pointless for the RPi's power input to carry data as well. I have a Rev.2 board so I'll try this, and let you know how it goes. @Shpaget: If the hub requires 2.5A from the mains, it might over power the Pi and ruin it. So splitting i...

USB Hub Powering RPi

Hi, I was wondering if I bought a powered USB hub, and used it to power the RPi whilst also connecting the usb ports of the Pi into the hub (so it would also work as a hub), would it still work? Sorry for the convoluted English. To put it simply, what would happen if the RPi was connected to itself ...

Re: GCSE Project: RPi Case

Wow... Thanks!  That's a lot of info, but I'll have a look at it.  It looks far too much for a GCSE project, but it might be something to do in the future!

Re: GCSE Project: RPi Case

I've just thought of some "crazy" idea:  Is it possible to "join" two Raspberry Pies to make them process quicker or really, for the heck of it?

Some sort of "RAID" array maybe?  And if so, how? (maybe I can factor it in into my design...)

Re: GCSE Project: RPi Case

<t>Thanks everyone!<br/> <br/> I was wondering, can the GPIO headers be programmed from within the OS?  Like can I limit the voltage or current going through the fans if I wanted to.<br/> <br/> Also, how do the GPIO headers work?  How do I program them or what can I do with them?  (Can I add tempera...

Re: GCSE Project: RPi Case

<t>Actually, that's quite a good point.  The only reason for it, is to spice up my project (and get extra marks for innovation and blah blah...).  Does anyone have any ideas of what to put in the case (using the GPIO 5v)?<br/> <br/> Besides, as promised; some of my (elementary) CAD skills:<br/> <br/...

Re: GCSE Project: RPi Case

<t>Josh Hodgson said: <br/> <br/> <br/> 2. Theoretically, yes, that would work, but you'd only have 300mA coming through it, based on the 1A usb input to the Pi ... If you were to use a powered USB hub inside the case, that would get you at least 500mA+ for the fan. My guess is a 40mm fan would be s...

Re: GCSE Project: RPi Case

<t>Hi,<br/> <br/> For a DT GCSE Project, I was thinking of designing and building a case for a Raspberry Pi Board B.<br/> <br/> I'll post some CAD designs later, but I want to ask a few questions:<br/> <br/> 1) Can anyone provide accurate dimensions of the board and ports?<br/> <br/> 2) If I get a 4...
