Hi there,

I realise that this is a very tenuous mbed link but I will explain. I have just completed and posted an Instructable for wireless power meter monitoring using a couple of Arduinos and a pair of XBee radios.

http://www.instructables.com/id/Watts-your-consumption-Wireless-Power-Meter/

It is a contest to win a laser cutter so any votes you might want to give it would be appreciated! That being said, it does lead on to what I intend to do with the mbed next. In step 7 I talk about a device that can sit on a network and serve up logging data without having to have a computer turned on. For this I intend to roll out my mbed and get the following components working: Ethernet (for obvious reasons), XBee radio (actually Serial comms so not as difficult as it might appear), SD card access (for large scale data storage) and possibly an LCD for one button checking of current usage.

Given I raised the question a couple of months ago, is anyone interested in the mbed protoboard? I wrote the ideas up on the CookBook but never got much feedback apart from Chris threatening to wield Eagle across the ideas!Any takers as this would get me up and running very quickly (and selfishly!)

Hi Matt, 

That being said, it does lead on to what I intend to do with the mbed next. In step 7 I talk about a device that can sit on a network and serve up logging data without having to have a computer turned on. For this I intend to roll out my mbed and get the following components working: Ethernet (for obvious reasons), XBee radio (actually Serial comms so not as difficult as it might appear), SD card access (for large scale data storage) and possibly an LCD for one button checking of current usage.

I can think of a few things that might be of interest :D 

• Rolf has got the first cut of both a http server + client working
• I wrote a first cut SDCard driver and filesystem 
• Chris has done a cool little breakout board, featuring MicroSD Socket, Ethernet Socket, and even Power-over-ethernet

Let their powers combine :)
Chris: Any chance you can post about the breakout design
Rolf: Any chance of an update as to where you are with http server/client

This sounds like an ideal test project to help test/develop this stuff!

Hi All,

Following on from Simons post, have a look at :

http://mbed.co.uk/projects/cookbook/wiki/mbed-BoB

I'll take some more pics tomorrow... so you get to see some other angles.
Any other info you need or want added, just ask!

Cheers,
Chris

Wow just what I need. Where do I sign up for one :-)

It's got most of the things that I captured here:

http://mbed.co.uk/projects/cookbook/wiki/MBEDDevelopmentBoard

It would be great to see either an RCA connector (for TV Out) or VGA but I guess space is a bit limited! Can you still access the pin outs that aren't connected to a component? (if you understand what I mean)

I've added this link to the mbed-BoB page, and added some notes as to how we ended up with what we have.

Yeah, anything that required other circuits was out, and I tried to stick to stuff that was a direct interface of the mbed. It’s a compromise...

Can you still access the pin outs that aren't connected to a component? (if you understand what I mean)

Oh yes! So the connectivity was chosen that doesn’t interfere with the pin it is connected to if it is not in use.
Have a look at the layout picture...the mbed is socketed in a pair of 2x20 headers. They are on a 0.9" pitch so that the mbed sites in the closest two rows, and you can stick wires into the outter two rows, which are on a 1.1" pitch.

I've also make veroboard daughter card with some long SIL pins that sits over the mbed. I've not used it for
anything real yet, but it feels like it might be useful :-)

I'll stick another photo on the page...
Cheers,
Chris

Chris,

Fully understand the compromise side of things, its what I do for a day job :-)

Brilliant move on the double row of headers. Its just what I was trying to allude to with the whole docking bit in the
MBedDevelopmentBoard piece.

So, who can I pay for one and when can I get one? :-)

I just stumbled upon this http://mbed.org/projects/cookbook/wiki/MBEDDevelopmentBoard. Well, we have developed one such base board. Check out NGXs mx-baseboard for more information.

Hi Ashwin,

Great work! Feel free to make a page for your board under the new cookbook (e.g at http://mbed.org/cookbook/NGX-mX-Baseboard) and link to it under the baseboards section. That way, people browsing will find out about it.
