WIZnet iMCU 2010 Design Contest Winners
WIZnet Open Hardware Platform
T
he WIZnet iMCU Design Contest 2010 
challenged engineers across the globe to 
incorporate the W7100 Internet MCU (“iMCU”) in 
creative embedded design projects. The W7100 
is an Internet MCU integrating a hardwired TCP/
IP  core  with  an  8051 processor. It  makes  an 
easy-to-implement platform for applications that 
require a network connection. By combining the 
latest  hardwired TCP/IP chip with  the  benefits 
of the W5100 and 8051 MCU core, the W7100 
provides a one-chip solution for all embedded 
Internet  projects. With $15,000 in cash prizes 
up for grabs, the competition was fierce, with 
innovative  projects  coming in  from locations 
such as the United States, Romania, Australia, 
India,  and Japan. The  judges’  results are  now 
nal. Congratulations to the winners!
FIRST PLACE
Net Butler
T
he innovative  Net Butler is  a multifunction 
design used to control, monitor, and 
automatically  maintain a  home network. Built 
around an iMCU7100EVB evaluation board, 
the design has several functions: it serves as a 
DNS proxy with a domain name block list and 
an  activity  log  display;  it  tracks  and  reports 
on connected  network  devices;  it  operates as 
a web server for viewing system activity and 
configuration settings;  it enables you to  easily 
manage a Wi-Fi network via push buttons, a 
webpage, or a timer; and it downloads and 
displays up-to-date weather information. Each 
task can be individually enabled or disabled, 
and most of  them  have  several  configuration 
settings.  The  system  includes  a  bootloader 
for downloading new code over the network, 
so adding new functions is a straight forward 
process.
