== ADSL Wireless/Ethernet modem ==
 +
 +
Hello,
 +
 +
Does anybody have a schematic for ADSL modem - either for wired Ethernet or wireless?
 +
A design based on a Linux supporting CPU would be highly useful. Searching on the net doesn't yield any easy results.

Hi,
 +
 +
Thanks a lot David. I may be a bit too demanding, but I was looking out for a nearly 'readymade' schematic, which I could implement. I am not too good at analog electronics, but can understand and design digital interfaces. Hence a schematic for the ADSL decoder section and its interface to a micro-controller will help me.
 +
 +
Thanks again !

Requests[edit]

I would like that the Bicicle LED POV project is added under POV projects. Here is the link: http://code.google.com/p/bicycleledpov/

Thank you.

Done. --DavidCary 08:26, 10 July 2008 (PDT)

Check Out Open Source Motor Controller[edit]

Greetings, fellow roboteer.

Have you tried: [1]


What is this "Open Soekris" embedded system on SourceForge ? --75.37.225.73 07:27, 9 May 2007 (PDT)

There seems to be a lot of overlap between this projects page and the open source electronics page. What is the right thing to do? --DavidCary 09:19, 7 June 2007 (PDT)

Options:

  • move the list of all the specific projects to the projects page. Keep open source electronics as a general definition, with a link to the projects page.
  • ... Can you think of a better way to handle this?

ADSL Wireless/Ethernet modem[edit]

I did a bit of googling -- '"adsl modem" reference design' seems like a good search string.
I see that at least one commercially-available ADSL modem already runs Linux.

XMEGA XMultiKit Development Kit and Oscilloscope[edit]

How can I add my project to Open Circuits? XMultiKit

XMultiKit is a development kit for AVR XMEGA microcontrollers and a dual channel oscilloscope with function generator.

I mentioned it at oscilloscope. Would a page at XMultiKit help? How else can we help? --DavidCary 21:22, 27 January 2010 (UTC)
