Jon Hylands full speed wifi board approaching :)

Its taken a little longer than I originally thought - had lots of power issues, and some timing issues also.

I have a bit more software work to do - I want to implement a SYNC_READ on the onboard ATmega164, which will allow you to retrieve values from a bunch of servos with one network transaction.

Price is going to be $200 USD. They should be available on my website in a couple weeks. (http://www.huvrobotics.com)

"So, my "new" wifi module (from ConnectOne) has passed both tests - I can hook it up to my router and get an IP address, and I can talk to it over the serial port (using an FT232) at 1 Mbps.

I'm going to start laying out a new board for this, but it looks like the full speed wifi board is going to become a reality."

We've almost got this working with an ATmega164. I've got a new PCB coming in on Tuesday, and hopefully that will solve the problem I had with the old one.

Assuming this new PCB works, I should have this new wifi board available within a few weeks.

That's the last one - the TQFP44 layout I used was the wrong size, so I had to do a bunch of hacking on the board to try and fix it, and it still had problems with lines shorting. I also had to use an external regulator, as the SOT-223 regulator I was using couldn't hack the current draw (about 250 mA).

I've fixed the layout, and changed out the regulator for a TO-220 version, and hopefully this is just going to work.
