1  Hardware and U-Boot firmware / Hardware / Solar Sheevaplug on: August 12, 2011, 12:03:50 AM
Hi all,

I'm looking at converting my Sheevaplug to run off Solar power, much like the one found here: http://www.earth.org.uk/note-on-SheevaPlug-setup.html

I'm not an electrician by any means and don't know what sort of solar panel, or battery supply I should be looking at. If possible could someone familiar with it link me up to the correct parts?

Eventually I'd like to power a small esata hard drive, however this can wait until the sheeva is setup as I'd imagine it'll need more power due to the rotating disk.

Thanks for your time Smiley

I'm very disappointed with its specs.

800Mhz is a major step down, especially when you can pick up a BeagleBoard which is 1Ghz w/ 1GB RAM and has an inbuilt graphics chip. Its actually no more expensive either and its a doodle to pick up a cheap project box from Maplin or similar to use as a case.

Very disappointed. The Sheeva platform has been stale for over a year, with a release of the dream plug which was effectively just an updated SheevaPlug. After all this time you would have thought that we would have a 1.2Ghz sheeva with 1GB RAM by now! Sad

NewIT talk about power the plug via a powered usb hub , but not heard of powering the plug via the ethernet cable when you haven`t got a power over ethernet router connected .

Is it coming via the Esata port ?

Not got anything hooked up to esata at the moment. I did a little test - it will work if I leave either the USB hub (powered) connected, or if I leave the ethernet connected. With ethernet I tested it plugged into a cheap 10 10/100 switch as well as plugged into a homeplug and then finally my Mac Pro. It worked on all of them!

Hi all,

I've noticed with my Sheevaplug (eSATA edition) that if its powered up, with my USB stick plugged in, along with an ethernet cable, I can pull the power cord out, and it stays on. The current must be coming through the ethernet cable, but I'm not sure this is supposed to be happening!

Anyone else have the same "issue"? It's pretty neat, but I don't think I would wanna leave it running like that at risk of burning something out!
5  Hardware and U-Boot firmware / Hardware / Query regarding using USB -> Molex (modded for SheevaPlug) on: November 16, 2010, 04:45:57 AM
Hi all,

I've got my first SheevaPlug on its way from the new IT folks. I've read a lot about the power issues and *think* I may have a possible solution to test on my new plug.

Basically, from photos (http://computingplugs.com/index.php/Opening_the_box_and_first_boot) it looks like the Sheeva mainboard uses a floppy drive style power connector (officially called a Berg connector). If so, it should be possible to use a usb -> Molex cable and change the molex connecter out for a Berg connector.

Would you say that this is correct? If so, you can but USB -> Molex connectors, or make one (http://forums.bit-tech.net/showthread.php?t=89344). The only difference would be instead of using a standard molex plug, you use the Berg one, which has the same pin layout (http://en.wikipedia.org/wiki/Berg_connector).

The main difference would be the pin layout WOULD need to be modified to work on the Sheeva.

From this image (http://computingplugs.com/index.php/File:J3.jpg) you can see the layout that needs to be used.

I'll have to have a play around when I get mine, but if anyones tried this or found a flaw here please do post!
