The watchdog reset does not reset the WizNet 5100 chip. Only a true hardware reset does. You need an external watchdog/reset circuit to reset both the ATmega and WizNet 5100.

Get rid of the regular voltage regulator. It converts all unnecessary power into heat. By removing or bypassing the regulator and use a switched mode regulator, there's minimal heat dissipation (just like the 802.3af PoE regulator does).

@Paul: Reading your message now, sorry for the delay. I've switched to the Raspberry Pi. Much more programming space, ability to use background tools/apps since it's Linux based and more stable on long term usage.

You need to change the bootloader to load the OS from SD into memory. I've seen some adapted bootloaders that are capable to boot/load the compiled sketch from SD or TFTP. Running the OS straight from SD is not possible since it's serial memory. The SD card size is limited to 2GB due to the FAT form...

Use plastic PCB Fasteners. Like the Skiffy Series 100

First of all, I would seperate GPS data from other serial data (unless you're simulating something).

Second, use TinyGPS and a second SoftSerial port to connect te GPS to. TinyGPS does all the calculations.

It looks like the maximum size of the compiled sketch is less in 1.0.1. About 1200 bytes less and all works fine. However,my predefined texts are no more availbale in the sketch and has become useless.

If installed the new Arduino IDE 1.0.1 to test the several bug fixes. However, the result is that I'm not able to upload the compiled sketch to the EtherTen anymore. Besides the board settings for the Arduino UNO I've tried all other board types, each of them resulting in the same or a different err...

Found something interesting that speeds up the disconnecting in some cases. There is an option in the HTTP/1.1 header fields that tells proxy servers to disconnect immediately after the connection has finished it's task. Some more references can be found here in RFC2616 , section 14.10. The part wit...

As written in this thread , problems occur when the DNS contains non-printable characters. I've tested some more by modifying the library so the last three characters of the DNS name aren't the CHAR values of the last three bytes of the MAC address but normal readable characters (a-z, A-Z, 0-9). All...
