  • Does anyone have the dimensions for this board? I wish sparkfun still included the aprx dimensions in the pictures....

  • I am attempting to use this shield with the redboard and basic wifi webserver that shows the value of analog pins. Whenever I power up it tells me that the shield is not present. I am not sure what I am missing!? I have tired dumping the code through 1.0.2 and 1.0.5. Any help is greatly appreciated. Ultimately I am planning to turn this into a wifi weather station using the weather shield. Thanks!!! (forgive me if the code pasted below doesn't look right in the forum... first time to post code here)

    /* WiFi Web Server

    A simple web server that shows the value of the analog input pins. using a WiFi shield.

    This example is written for a network using WPA encryption. For WEP or WPA, change the Wifi.begin() call accordingly.

    Circuit: * WiFi shield attached * Analog inputs attached to pins A0 through A5 (optional)

  • I couldn't get this thing to work and I only have one 2 gig SD card. I downloaded the formatting software and now it works! It's a surprisingly nice little board. Why you need that software to format an SD card is beyond me but now the little thing works. Now the front door to my office will say "please enjoy your trip through this door" (hitchhikers guide to the Galaxy reference" or maybe just welcome....

  • Do these wheels have any traction? I am wondering if they will grip sheet metal...

No public wish lists :(
