NOTE: this webserver and the accompanying code are obsolete. Do not use this for any new designs !

The 4th generation of Webster represents the final iteration of this idea (I hope anyway). It is functionally equivalent to the 3rd generation design except that it is hosted on stock NetBurner, Inc. hardware which makes it very easy to build. Webster 4 was used to host our personal website for 3 years but has been since been retired. Our website is now hosted by a web hosting firm.

4th generation Webster's features include:

  1. Low power operation. Only 250 mA is required at 3.3 volts or about 0.8 watts.
  2. Small size. The packaged web server is about the size of a hardbound book.
  3. 100 baseT Ethernet connectivity.
  4. Support for static and dynamic IP address assignment
  5. Based upon a 32 bit ColdFire processor running at 147 MHz.
  6. Support for basic authentication for web site access control.
  7. A built in SD memory card interface (64 GByte max) for web page file storage.
  8. A built in FTP server allowing for in place update of web site content
  9. Easy to build. Webster2 runs on stock, inexpensive NetBurner, Inc. hardware.
