Hi All,
I would like to inform you that beagle board is now available
@Tenet Technetronics, India.
For more information about this company, Kindly go through mentioned
below link :
Just so everyone know, Tenet Technetronics is not an authorized Beagle distributors and we will not honor the warranty for anyone that purchases boards from them.

It is worthwhile to mention the delivery times of the board after
ordering.
I ordered from Tenet and got the product after 11 days (that too after
a lot of heated mail exchanges)
with full payment made in advance. The explanation given is that
they didn't have stock and i ordered
on the same date as this post. So i have no clue of what is really
meant by "beagle board is available"

It's true! We have completed the proof of concept of the Pico Node using
a BeagleBoard to replace the PC normally used to run internet linking nodes
for Amateur "Ham" Radio. Below is the original announcement as posted by Jim
Dixon (WB6NIL)
Begin announcement:
We (Dale Weber, N7PKT and I) have been working on porting
Asterisk/app_rpt to the TINY (about 3.25 x 3.25 inches) BeagleBoard (arm-based
Linux system), using the native (built-in) audio and GPIO hardware to directly
interface to radio systems.
As of this evening, we have success!!
The BeagleBoard is capable of talking to 2 radios (either half or full
duplex) using the radio's COR and CTCSS decoders (sorry, there isnt enough CPU
power to do the DSP processing, like in chan_usbradio). It will also talk to a
URI (or 2 or maybe even 3??) using chan_simpleusb.
I am designing an I/O card, which properly conditions both the analog and
digital signals in and out of the BeagleBoard, and will provide general-
purpose GPIO pins for whatever the user's needs are. It also may contain a DC-
DC converter, so that the system may be powered from a 12 volt (well, like
maybe 9-18 volt, actually) DC input, allowing use in an automobile and various
configuration of battery/solar/wind-power.
For those interested, I posted the working chan_beagle.c source in the
SVN, and will update it as the project moves along. Currently it only supports
1 fully operational channel, but that's because my test hardware was not
intended to do anything other then that.
We will also post the working kernel sources, plus an entire image of the
4GB flash card, for ease of installation.

There you have it! The Pico Node is well on the way to becoming something
others can take advantage of and use also. 
We have done most of our
development right on the BeagleBoard, including all kernel and software
builds. These nodes are used to link repeaters and simplex radio setups over
the internet, allowing Hams to link up worldwide.

Do you take advantage of the TMS320C64x+ DSP in the OMAP3530?
Congratulations!
I just designed a 10.8V to +5V high efficiency DC-DC converter to power BeagleBoard from
handtools Li-Ion battery back. It would probably work with car battery “as is” provided that
you make the proper cables to it. The schematics (Eagle) would be easy to use on your board and the are needed is only 1.225" x 0.6". I am using the TI TPS54331 converter. The board has 10 mohm current measurement resistors on input and on output.I can sell a single prototype board for $25 just to cover the prototype board cost to me.

I wondered the same - there is a lot of “extra power” there!
Also did you set the voltages for the 720 MHz operation?
And finally, the DMA is a wonderful resource to implement
routine transfers with light processor load.

No, we are not currently using the on board DSP.

I guess you have plenty of BB’s power untapped!
Did you do the software profiling? Where is the
execution time spent? Which language did you
use in writing your application?

I guess you have plenty of BB's power untapped!
Yes, we have much power left untapped on the BeagleBoard.
Did you do the software profiling? Where is the
execution time spent?
No profiling has been done so far.
Which language did you use in writing your application?
The application is a fork of the code for the Asterisk PBX that has an
additional heavily modified app to interface to radios. Everything is written
in C/C++. The porting was done by Jim Dixon (WB6NIL, head of the AllStarLink
network), and everything was built natively on the BeagleBoard. I've served
mainly as support to help Jim do what he does best.

Any links to to sources?
Yes, indeed, as soon as everything is in place I will post the links
here.

It's somehow limited to 10.8V input voltage? The part you're using allows
wider input range. I would like to have something to power Beagle from the car
battery, be it 12V or 24V. Is it possible with your design? Thanks.

Hi Petr,
I checked my design. The input can be up to 28 volts.
The “eco mode” converter can deliver up to 3 amps of 5 volts.
Plenty for both BeagleBoard, USB devices, and expansion cards.

I've started a site for all things having to do with Pico Node at
http://www.n7pkt.com . There is not much there yet, but this is where to go
for all Pico Node info and related files.

Koen, we've started a brand new site for everything to do with Pico Node,
and software for it. It's http://www.picklejar.org - check it out. It's
pretty sparse right now and very plain, but you will find everything you want
to know about Pico Node here. 
We're making great progress on the expansion board design and hope to
have the first few boards for testing within one or two months. We are only
supporting the BeagleBoard-xM at present because it has more memory. There is
also a fellow who is persuing the DSP aspect of the software now and wants to
port his DSP code to the on board DSP of the BeagleBoard.
