Auto Fill Circuit for Laser Cooling Loop – Ethernet Data Logging

Here is an automation solution with a ethernet usage. The code and diagrams are also there. This is something that covers many aspects of engineering in one project. Try such things out to learn, only after you have mastered the basics.

“The Ethernet connection is based on an XPORT form Lantronics. Basically it lets you use a serial port to send things over Ethernet. A PIC microcontroller with an A/D converter digitizes the pressure, the pressure set point, the high and low pressure alarm points and the supply voltage (since everything is ratio-metric). “

This project, called “Simple-Timer” is a programmable Timer and electronic switch with an integrated LiPo Battery Monitor that is based around a PIC microcontroller.

Simple-Timer

The “Simple-Timer” includes a fairly accurate timer that is programmable (via pushbutton) by the user and can be programmed to time a 5, 10, 15, 20,25 or 30 minute event. When the timer/switch is enabled (tap small pushbutton), the onboard LED indicates the output is active by lighting solid (the circuit also outputs the same voltage as your supply/battery voltage using a PN2222 NPN transistor or a high current MOSFET).

CARACA is a home automation project based on a net of interconnected programmable circuits suited to perform different tasks like switch on/off appliances, decode commands from Ir remote control units, control thermostats, measure temperature and more.

CAn Remote Automation-Control with AVR

Every node of the net communicate each other through a robust protocol (CANBus), and the status can be monitored by a PC possibly connected to the Internet.

Interface an Arduino to electronic sensors to make these basic measurements. These are needed in your Garage, Basement, Attic or Loft; The Living Room too, Humidity and Temperature have an impact on your health and also the life of the furniture and wood construction material too.

Temperature and Humidity with Arduino

This device will show air temperature in C and F, and % Humidity on an LCD display. A DHT11 Humidity and Temperature Sensor converts the Real world Parameters of Temp/RH into readable Volts for the Arduino A/D section.

Web51 is a complex project of connecting an Intel x51 compatible processor to a Realtek RTL8019AS network controller. The result is a very low-cost Ethernet interface. Since a well-known x51 architecture is used, even small and medium-scale businesses can now network their devices.

Project is free. Almost all source codes are available.

Embedded 8051 TCP-IP WebServer

ET have produced a remarkable board in the WEB51. It is based on the popular Atmel AT89C51RD2 microcontroller, and features the RealTek RTL8019AS full-duplex ethernet controller chip.

You get a huge 64K In-System-Programmable FLASH memory for code and web content, backed up by up to a further 4 optional, I2C addressable EEPROM memory chips.

The ET-WEB51 TCP/IP Ethernet Web Control Board comes preloaded with TCP/IP software that allows you to control outputs, sense inputs and write text to an LCD. All this across the Internet via a standard browser.

“From controlling appliances on your home network, to monitoring industrial processes on the other side of the Earth, the ET-WEB51 can do it all.”

Invisible Accent Light with BlinkM MaxM & FreeM

“Sometimes you just want a little extra light in a room. With RGB LED tape, you can put light anywhere. But controlling its brightness and making it the color you want is a bit harder. A BlinkM MaxM can easily control LED tape, either as a stand-alone device, with an Arduino, or your computer via a LinkM.”
