Re: New post on the front page: a date that'll interest you, and a datasheet that will too.

I'm unimpressed. Almost exactly a month ago production start was announced, and then suddenly a key component - the oscillator - isn't available in the Far East, but readily available in Europe and nobody can fill a shoebox and ship it overnight to China? Huh?

Not impressed.

Re: Adding more voltage to r-pi?

Felix said:

No I didn't. I said you need a separate power source for your screen. That's unrelated to the R-Pi.

Re: Adding more voltage to r-pi?

<t>That isn't a parameter for you to play with. Higher voltage and you fry the board.<br/> <br/> However, I think you ask if you can add more power (watt, not volt) and then the question becomes "more than what?". The R-Pi has an on-board fuse of 1000 mA, so that's the limit (5W).<br/> <br/> Any pow...

Re: Suggestion: Tiny PCB for DC-anything to 5 V DC

As the solution should be able to match the 1000 mA of R-Pi's polyfuse, I'm a bit skeptical about the Zener diode solution. The alpha R-Pi did use a active regulator and the R-Pi team probably considered this short cut too.
