Drip Irrigation Controller
The irrigation timer with advanced planning (ITAP) is a truly next-generation irrigation control system. Featuring a WIZnet WIZ810MJ network module and an Atmel ATmega168, the innovative controller directs user interaction into a standard web browser. As a result, the system doesn’t have a keyboard or an LCD. The single-controller unit can manage up to eight zones. No software installation is required. Its functionality is split between the browser-based user interface and the hardware-based web server, data model, and control logic. The web server is used to read and write the internal data model. Its other function is to return files stored in internal program memory. Precision irrigation control is now a reality because the system provides useful information such as watering schedules and zone activity.

LED News Ticker
The handy LED News Ticker brings the news to you by displaying up-to-date headlines in a scrolling format. The system features a main board and eight slave boards attached to dot-matrix LED displays. The main board features a Microchip Technology PIC18F2525 microcontroller connected to a WIZnet WIZ810MJ Ethernet module, which uses the W5100 to provide an easy-to-use interface to the Internet. The LED News Ticker requires no interaction to operate. Once powered up, the device immediately connects to the Internet and downloads news updates every 15 minutes. It handles all DHCP leasing and DNS resolving, allowing you to use dynamic IP addresses.

DMX Portal
The well-designed DMX Portal is an affordable DMX lighting controller. You can use the novel system to remotely control up to 512 channels through an IP-based network or directly interface them to embedded systems with a serial connection. It was designed to be perfectly suited for designers who want to off-load DMX management and refreshes from the main system controller. It’s also useful for distributed lighting systems where low-cost Ethernet wiring is more practical than expensive RS-485 wiring. The prototype includes an external EEPROM for scene storage and a Microchip Technology PIC18F4620 microprocessor. A WIZnet WIZ810MJ evaluation board is connected to the SPI on the PIC development board.

Portable Network Service Monitor
This portable network service monitor was developed to help network administrators supervise datacenters. The handy monitor—which features a WIZnet WIZ810MJ module and Atmel ATmega128 microcontroller—is equipped with a 4 × 20 LCD that can display important messages from any configured server in a local network. It also continuously checks connectivity to predefined services on different machines. When problems occur, it triggers an alarm.

ThermoNet
The ThermoNet is a web-based, remote control, residential HVAC thermostat. The well-designed system includes an easy-to-use LCD front panel and a built-in web server. The front panel includes four buttons: Mode, Fan, Up, and Down. The hardware consists of a WIZnet WIZ810MJ module connected to an Atmel ATMega128 microcontroller external memory interface via direct memory mapping. An Atmel DataFlash chip provides ample storage for embedded web pages and is easily updated with new web pages and other files via a Windows-based program.

FATE: Flexible Audio Transmission Over Ethernet
This project addresses the idea of digital audio for the masses. The purpose of flexible audio transmission over Ethernet (FATE) is to set up a simple dedicated wired Ethernet network. You can then use the network to coordinate the distribution of high-quality audio signals throughout a building and the area around it. The useful design uses a full parallel bus interface to a WIZnet W5100 IC. The IC is memory mapped on the “auxiliary bus” (expansion bus) of the processor core. Its register values can be seen and manipulated at any time. Interrupts aren’t used.

Web Camera
The versatile Web Camera system can take a picture at a resolution of 640 × 480 or 320 × 240, pan the camera horizontally and vertically, and change its IP and gateway address to match a network. Photos are taken with a C328 JPEG compression module, which serves as a JPEG-compressed still camera. The host can send a snapshot command to capture a full-resolution, single-frame still picture. The picture is then compressed by the JPEG engine (OV528) and transferred to the host. After each photo is divided in 64-byte segments, a WIZnet WIZ810 Ethernet module transmits the packets over the Internet.

Time Server
The well-designed Time Server keeps a master time and date clock that is synchronized to the U.S. WWVB time-code signal. It exists on the Ethernet network and serves time and date information according to the SNTP, DAYTIME, and TIME protocols. Client devices can connect to the system, request the time/date, and synchronize their local clocks. Because the Time Server doesn’t rely on Internet servers, it can be used in secure networks that aren’t connected to the Internet. A WIZnet W5100 provides the interface to the Ethernet network. A Freescale MC9S08QG8 microcontroller is used to decode the time-code pulse stream, update a real-time clock, and serve time/date information to clients on the Ethernet network.

Greener Lawn: A Sprinkler Control System
The well-made Greener Lawn system gathers historical weather data and forecasts and then makes intelligent watering decisions based on that data. The design features an ATmega128 processor connected to the Internet through a WIZnet WIZ810MJ. The weather forecasting and rainfall totals come from the National Weather Service’s FTP server. Linux shell and Perl scripts gather the data and parse out the rainfall totals. This is stored as plain text files on the Linux web server. A PHP script running on an Apache web server enables you to configure the sprinkler controller. A second PHP script ties all of this information together into a single downloadable file that is requested by the WIZ810MJ.
