It`s a miniature 10/100-MbBit Ethernet module that includes an integrated microcontroller. Price is less than $60 a pop. With its minimal dimensions of 1. 38-in. x 2. 16-in. (34. 5-mm x 54-mm) the communications module can be used for compact designs such as surveillance systems, or vibration analysis equipment. The module includes a 3. 3-V regulator and 5-V-tolerant I/Os.

The embedded microcontroller is a Silabs (Silicon Laboratories) Type C8051F021/23 device, which, as the part number indicates, is an 8051-derived processor. This block diagram (click to magnify) illustrates some of the on-silicon features of these processors. The C8051F021 or /23 is really what`s responsible for the rich feature set of this product. These controllers are capable of delivering 20-MIPS peak performance with supplied clock options. An-board JTAG connector eases debug and downloading of code. The IP Avenger`s processor works with 64-kbytes of application-programmable flash, and 4-kbytes of SRAM. Thanks to C8051F021/23s, the mini-module also offers two UARTs. These serial channels let the module adapt to numerous gateway applications. RS-232 or RS-485 gateway applications typically require very few external components. The module also includes no less than four channels of 10-bit/12-bit A/D conversion. These analog-inputs offer PGAs (programmable gain amplifiers). You also get up to seven channels of 8-bit A/D conversion, also with PGAs. On the output side there are two 12-bit voltage-DAC (digital-to-analog converter) channels. A less-than-$200 evaluation kit contains the tools for starting development. The kit contains one IP Avenger module and a JTAG-serial adapter. An IDE (integrated development environment), with debugger, comes on a supplied CD-ROM. The CD also includes a copy of binaries, as well as a...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
