Run an Odroid C2 off a Pogoplug power supply

Hello everyone!

I’ve got a bit of a project planned and I need your help. I’ve been running an E02 for quite some time (see http://forum.doozan.com/read.php?8,32824), but I want to switch it out for something with a bit more oomph. Gigabit ethernet and USB2 is still fine. I am currently playing with an Odroid C2. In terms of CPU power it’s a beast, compared to the E02 - Quad core 1,5Ghz 64bit Arm - runs the whole lot I was running on the E02 and is bored all the time. So lots of room for additional stuff.

Now, the good thing about the E02 was: It was a pretty sturdy package, power supply never failed me, etc. In comparison, the Odroid is very easy to damage, no good cases available, power supplies are a bit of a mess, etc.

What I would like to do is: Use an old Pogoplug case and if possible reuse it’s power supply. From reading through the forum, I learned that the V3 has a 12V power supply, so that’s no good, as the Odroid runs on 5V. The E02 has too my understanding 2x 5V available.

Do you think it’s feasible to grab one of the 5V rails and power the Odroid off of that?

(In case it would draw too much power, the next and unavoidable and maybe stupid question is of course: Could I combine the two 5V rails and use them combined?)

Any help its greatly appreciated,
snady

PS: If anyone would like to get rid of an old or broken E02 and is happy to ship within the EU - I am interested.

Yes - i have done it before, nice smooth dc voltage out of it.

there is no way the odroid will need the rails combining, the power supply can easily supply 4a @ 5v

Nice :) Did you do this mod permanently or just temporarily to see if it work?

The "weak" point in the Pogoplug E02/Pro is the power supply connector. If you play with it too much (pull the plug in/out), eventually the solder point got loosen. I had that happened to my Pogo Pro V3, but I had a bricked Pogo E02 (NAND went kaput), so I was able to reuse that power supply.

4 amps on each rail or combined?

What would combining look like? soldering the two +5V together, or would I need to do something smarter (sorry, this probably sounds completely idiotic, but I am a complete electronics nook).

Dammit... bought another Pogoplug (V3 PRO black one with Wifi). Debian was already installed. Planned to gut it for the Odroid project. But it's so nice... I don't want to break it ;)

If I may ask: Who did you buy it from and how much?

adorama.com or adorama on ebay (if you want to use your ebay gift card)

$9.95 for SKU: COCPOGOP01 MFR: POGO-P01

Pogo-P01 and Pogo-P02 are both Pogoplug Pro.

Free shipping.

Thanks.

Mine was used, came with 16Gb stick with Debian installed and was roughly 20$ (allegro.pl). Yup, that stuff is pretty expensive here, compared to the US

Have you booted it up and check which version it's running?

uname -a

when you do

fw_printenv

does it list u-boot envs?

What are you searching for exactly? (Also: I am not sure anymore if I should slaughter the pink or the v3....)

That's all I wanted to see! This has the latest uboot and newer kernel that I released here, it should serve you well :)

The Pro feels quite a bit snappier. I think I'll keep the Pro as backup and cannibalize the E02 for the project.

First test: E02 Power Supply (1 rail) on the Odroid: Works just fine... was a bit of a chewing gum and duct tape job. Need to do some soldering over the next days...

not had access to the tinterweb for a couple of days...just read your questions, you seem to have answered them without my input :)

Well, when in doubt, I am all for the pragmatic approach... could have gone wrong though... And your comment encouraged me to test it with one rail. So the comment is appreciated :)
