PIC RISC microcontrollers - Peter Luethi
There are also tools for using your PC for measuring or regulating electronic applications. I'am working on several projects, e.g. a precision digital altimeter to use in my radio controlled airplanes.

Precision Digital Altimeter
The current concept incorporates a wireless transmitter and receiver and is thought to be used for remote controlled airplanes or appliances with two seperate parts. In other words, we have one dedicated transmitter (acquisition, filtering) and one dedicated receiver part (user-interface, look-up table, calibration, storage),....

The PICList -Schematics and Code
PIC 18F4550 USB 16F877A IO RS232 Eval Board
The design is essentially a double evaluation board for the chips 18F4550 and 16F877A. It contains also a MAX232A serial module having two transmitters and two receivers with the ability to connect either to 4550 or 877 microcontroller. Each microcontroller port ends up to a pin header in order to give interconnection capabilities to the board for future experiments.

If you want to do such a project, use Opto-Isolation for High-Energy circuits for Safety. The Analog Value from Attenuator, Shunt, Current Transformer is amplified and converted to frequency then thru opto-coupler reaches uC. This protects PC and User.Be very careful in High Voltage and High Current. Use proper transducers and Isolation to Protect man and machine.
Compact USB Development Kit PIC18F14K50
The kit contains one fully populated low pin count USB Development Board, one spare board, one PIC18F14K50 Debug Header, and CD with docs.
PIC18F13K50/14K50 USB Flash nanoWatt uC
PIC Microcontroller with full speed USB 2.0 interface. Ideal device for battery-powered applications.
"The addition of mTouch(TM) touch sensing compatibility, a 10-bit ADC, motor control PWMs, and a host of serial interfaces make the PIC18F14K50 the perfect device to "Just add USB" to any application."

"Ethernet communication solutions offer access to the most widely deployed networking system. The TCP/IP protocol, which is at the core of this technology, allows total location independence and interoperability to any embedded application.".
"The emerging standard for flexible wireless networking specifically designed for embedded control. ZigBee supports stars, clusters and mesh networks of up to 64k nodes. Microchip supplies a free stack that supports a variety of transceivers."
MRF24J40MA 2.4 GHz IEEE 802.15.4 radio transceiver module.
Has a integrated PCB antenna, matching circuitry, and supports ZigBee too. Connects to many PICs via a 4-wire SPI interface. You can design wireless sensor networks and home automation systems.

Picoload bootloader microchip pic
Picoload is a Program which makes it possible to program a microcontrolor peak 16f87X or 16F87XA from microchip without having has to remove this one of the assembly by means of a connection series RS232.
A bootloader based on the bootloader of bigonoff is carried out on the peak and makes it possible to manage the connection series as well as the writing of the program in the memory flash.
