Embedded 8051 TCP-IP WebServer

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.

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.”

Periodic Table and other Calculators

Periodic table of the elements contains the basic data about the elements in five languages.

EniG. Chemistry Assistant 2.4 An expression calculator for fast calculation of molecular weight of compounds by simple entry of chemical formula (the element symbols can be written in lowercase letters). The calculator also provides a list of common physical constants and performs various conversions between English and metric units.

Scientific calculator Sci.Calc is a fully-functioning JavaScript calculator that contain of practically any common and many advanced calculator functions (cosine, sine, tangent, power, square root, exponents, etc.).


Learning Electronics by Hobby DIY is not Complete without a sound Knowledge of Materials, A Periodic table Reference will help in Understanding the Metals and Semiconductors.

Every Metal has a potential for a New Component Discovery, Even a Breakthrough in SuperConductivity at Room Temperature will change the way we build Gadgets !
