Hi All,

I have a Guruplug and would love to have a new plug for some other stuff.
I'm pretty satisfied with Guru, besides the fact that the NAND is a bit small and the heat issues with the GBit Ethernet.

I'm not sure if the heat issue is still in current GuruPlugs (I bought one of the first ones) and I'm not sure if I can take my lessons learned and apply them on another plug.

What I need is a small low power server running a webapplication (eibd, linknx, PHP)
I also would like to add some serial interface function
- I need 2 serial ports to communicate with my heat pump and air condition (I thought about a usb to serial adapter)

So any hint of what you would use and maybe why would be very helpful.

Thanks

I thought about the Raspberry Pi but I'm not sure how well/fast that one is.
The guru had a faster CPU but the CPU is older.
Are there experiences running something like eibd, linknx and knxweb on a raspberry Pi?

Or a CubieBoard which has SATA onboard:

The cubieboard looks pretty good.
Impressive tech specs for the low price.
Do you have any experience with community support of the board.
E.G. Linux distributions, bootloader, support (like this group), etc.
I just had little time to look into but Raspberry seems to have a huge community with lots of ready to use/modify samples.
The cubiebord though has the much better specs for a bit higher price.

Any thoughts / hints where this community meets?

Thanks

BBB: http://beagleboard.org/Products/BeagleBone%20Black

Another good choice is the Cubox: www.solid-run.com

Hope it helps,

Hi All,

thanks for all the great hints.
These are all very good looking machines and I'm amazed how many different products exist in this niche market.
But due to the huge hype and support that you can find for Raspberry Pi I went for that one.
I now made it to install the whole eibd/linknx/knxweb php/lighttpd stack in less than a day.
I used Raspian as the OS of choice and seems it was a good one.
Easy to load, cool setup screen which asks for all kinds of configuration options on the first run.
This really feels like a product.
If I compare this experience to the Guruplug experience, heat sink issues, JTAG hassle, strange ubuntu distro, lack of support ... to name a few.
It took me the evenings of a full week to get  the same stack running.

It will show over time if Raspeberry PI will be as robust and stable as the Guruplug was, but first impression is great.

Thanks again
