HiFiBerry team Hi,
this looks great! What king of power supply/voltage regulator are you using?
Can you provide use some of these pictures for our gallery?
Best regards
Daniel
P.S. I will later move this treat to "Your hifiberry installation". -
hifi Hi Daniel,
I used the following regulated linear power supply kit from eBay:
http://search.ebay.com/271543073435
It's based on LT1083CP chip which can handle 7.5A.
That's much more than enough :)
This power supply has two independent channels. I chained
them to have gradual dropout. The transformer gives 9.5V AC.
After rectifier it's 12.5V DC. I use that for LED in the
illuminated power button. The dropout on the first channel is
3.75V from 12.5 to 8.75V. The output from the first channel
goes to the input of the second channel. The dropout on the
second is the same 3.75V from 8.75V to 5V.
It's OK but I still think that the heat-sink of the second channel
is too hot. Probably instead of cascading I should connect two
channels in parallel as suggested here:

But that will need too many changes in the board.
Do you need more images?

pauloaspo Fantastic setup, congratulations. :) -
pete I love the enclosure, can you tell me where you got it from? -
hifi Here is the item number on e-Bay: 111409977226

It's a bit expensive but the quality is very good.
It comes with power button, power socket. All remaining
holes you have to make yourself.
On my picture you can see the wall/divider which separates
power supply. It doesn't come with enclosure. I found it in
my garbage.
Also I replaced the power switch by my own.
Good luck!
