Hello,
I'm planning to build a audio based (but video capable) streamer with Rapsberry Pi3. It's been a couple of month now that I own one with Volumio2 installed (and kodi 16 player on top) and almost everything works fine.
Now is the time to get a little more "serious", with a DAC hat, psu, hdd,.... and here is where the questions begins to rise! 🙂
- For the DAC hat I'm planning to buy a Mamboberry ls.
- The hdd I was thinking of the WDlabs 1Tb

I think that is optimised to work with raspberry Pi and the little cable (that gives power to the HDD and Pi and transmit data) that comes with it's kinda handy.
- And now the psu...
I don't remember on which post I saw the link of the teddyreg
TeddyReg | DIY | TeddyPardo
and seems to me a good start point (I must admit I don't have much experience with power supplies). I saw in other posts that the Ifi Ipower it's a winner but there's no much diy involved there 😉.
I was thinking to have two power supplies, one for the hdd/pi using a lt1083 for higher current, and the teddyreg for the mamboberry.
Is that possible (on the mamboberry website they say that only one psu is needed, but i think there is a way to separate the two) and is that worth it?
Finally I will like to have a on off button and here I have no clue. I've read projects that use some script, others "sensing" the power from the PI directly and control a relay. Someone can point me in a right direction here?
Any help, advice or idea is welcome!
I wish you all nice day

Little update on the psu and switch:
The psu consist in a Toroidal 30VA 2x12V, one rail goes to Teddyreg for the Mamboberry, the other one to the lt1083 reg. for Pi and hdd.
I found this circuit for the switch:

The problem is that is using it after the psu. I don't think is wise to have all the psu continuously live.
Can I use the same idea with a relay before the toroidal transformer?
(ie using this module https://www.sunfounder.com/sunfound...-pi-5v-dc-trigger-by-highlo-high-trigger.html)
Or am I totally wrong?
