Media center in a 3.5" HDD enclosure

Tue May 14, 2013 8:18 pm

Quick question, I am thinking of putting a pi + a 2.5" HDD into a 3.5" HDD enclosure. I am planning to power the pi from the 5v line of the power supply for the enclosure. The supply is rated for 5v @ 2A and 12v @ 2A, I would only be using the 5v line for the pi obviously, would there be enough current to run the pi and the drive? I would be using a Wi-Fi dongle and possibly a wireless keyboard too.

If successful this will sit under the TV as a nice small media center running XBMC :D

Over a week since you had a really good idea and you've not been even a tiny bit tempted to jury-rig it to test it? ;)

The simple answer is that it's feasible but it depends on the enclosure and it's power supply. So test it! (And let us know how you got on :)) As long as the Pi doesn't get more than 5v it can't hurt it. It should make for a nice media centre.

I'm still waiting on a micro USB cable to cut up to try powering the pi, plus this is one of several projects I have going right now :D I was just wondering if anyone knew anything on the topic. Ill see if I can try powering the pi through the GPIO tonight.

Oh one more question, would the wi-fi dongle still get signal inside a close metal case?

Well, the Pi on average requires about 750mA, how much power does the drive you plan on using require? Add the 2 together, if you're under 2A then you're good to go.

Tested and it seemed to work fine :D I had the pi playing HD movies from a 2.5" hard drive, no wifi, but ill try that soon.

@ski522 Its a shame I didn't see your post sooner, for some reason I completely forgot to check if the drive had a current draw listed on it. I checked after the test and its rated at 0.5A. My pi works fine with the wi-fi when I use a 1A power supply so even if its maxing that supply out (Doubtful) then that still leaves me with a spare 500mA from the HDD supply so thats good :D

That just leaves me to find out if the wi-fi to get signal and if there will be a heat issue in such a tight enclosed space.

I've been running a model B 256Mb in a 3.5" drive case with a 2.5" drive for several months [routed the +5 volt line to the RPi] I was using the wired socket
I've just this week disassembled it to replace it with a
Model A and a Camera ;)

no issues

Good to know! Thanks :D

Were you using A wi-Fi dongle, and if so, did you encounter any signal issues from the casing?

It works! :D

I couldnt get wifi working, but thats not a casing issue, it just doesnt work.

On that note, does anyone have any tips on getting RTL8188CUS based dongles to work in OpenELEC?

Hello,

Sorry for reopening the topic but I want to do the same thing. Can you please tell me if the HDD stops with the shut down of the Pi? What HDD rack are you using?


Thanks.
