Can the wifi on this shield act as a host, such that tablets and phones can connect to it without having to go through a router?

Are the EAGLE files posted here before or after the "green wire" fix was corrected?
I see from browsing the firmware source for this shield that some changes have been made. I really need a shield that can (1) act as an access point and (2) accept a hard coded IP address. Can this do that yet?
Did you ever take a shot at this? I am thinking of writing some custom firmware for it as well.
Absolutely not! Arduino sketches do not run directly on to this shield. The firmware for the shield can be updated but it is not written with the Arduino environment.

This is an extremely nice GPS receiver! Its very sensitive. I have a to story home. It didn't get much of anything int he basement but on the first floor its getting 8 birds with good SNR. When it has that many birds with good signal, VisualGPS reports error < 1 foot in all directions for several minutes. Can't wait to try it outside (its a little chilly tonight).
So far the only downside is the lack of a comprehensive command reference. There is a PDF with a bunch of commands but it is missing some important ones. like how to change the baud rate. It does tell you how to turn certain NMEA 0183 sentences on and off though. By googling around I think all the commands are available.
Perhaps before the sailing season is over here int he Northeast I'll get this on my boat. I probably have about 1 week left!

This paste spreads okay and reflows well enough in my toaster oven. I get solder bridges on chips with pins that are close (not technically "fine pitch" parts but close) and I have to wick them up. That's probably a stencil design issue.
But, this paste makes a mess. It is not water soluble and cleaning it off a Kapton stencil is very, very difficult. Lots of very hot water and water pressure does not do it. Even scraping the paste off with a squeegee does not do it. Bits of dried paste get stuck in the stencil apertures and on the surface of the stencil, and its very hard and time consuming to get it out.
I'll be using Kestor Easy 256 for the rest of my projects. Yes this stuff is cheaper if you only need a little bit, but its not worth the hassle.
Okay, I have the paste and the stencil is on the way...
Where can I get one of those nifty frames the guy in the tutorial has? I need one for an 100mm by 80mm board...
Thanks! I spent a day playing with an oven and the SPE controller. Can't wait to put an actual board through.
No public wish lists :(
