Then, others again claim to their ignorance and spend their life waiting for the next big thing.

And yet other people talk through their back side.

I called them. The next week they ll make available a minimal breakout board with ethernet  power usb and connectors. Others are expected by third parties
EDIT  end of september ....

These are all just good toys for us to play with :)

The Pi is (as Mike says) pretty poor at anything real-time with Linux. The timing even makes a servo pretty jumpy (http://www.doctormonk.com/2012/07/raspberry-pi-gpio-driving-servo.html).

It also draws 500mA about 10x that of an Arduino Uno.

BUT. Its fun, and its a challenge, seeing just what it can do!

I meant to also add, here are some of the things I have been doing.

Try experimenting with your programs' process priorities via "nice", and let us know how you go:

I have been doing some tinkering with ad-on boards as well. Not really ready for the big public announcement, as I have yet to assemble and test... but here is a preview of my project:

most of the work has been on the hardware side of things so far - next step will be focusing on making the software aspects as accessible as possible

Or anybody have any other suggestions for a sub $80 device capable of wireless and LAMP?

A full-blown LAMP server for under $80 might be problematic (although the ~$50 Geode board mentioned in the other big Pi thread might do it), but this board looks promising for running something like a thttpd-based web server. I haven't used one, yet: I got to the point of getting an order ready to go, but the client cancelled the project at the last minute.  That system wouldn't've had a database, but it was going to run a full webserver with CGI, and be able to send SMS and email alerts via mailservers that required authentication with SSL.  That company also offers a $110 board with 128M that's worth looking into.

Yea they arent in the budget.  I can still get wrt54gs for in the $60 range and dont want to go much if any higher than that for a replacement.
I'm thinking for $35 what the hell.  I'll just buy one, wait 3 months to get it, and then test it out.


For one, check EBay.
