Arabic Copt orthodox prayer book "agbeya" embedded inside a microcontroller

This device contains the prayer of the Copt orthodox ;the device consists of a microcontroller of type "AVR" , a SD card and , GLCD and a keypad. The implementation of the Arabic engine is too hard using "C#" also the EEPROM of the "AVR" is too small and the firmware is too complicated....Waiting the Arabic bible soon...

LED MATRIX driven by PC

This project consists of 2 LED MATRIX 8*8 soldered beside each other and controlled by a PC software named "Led Matrix Control" through a microcontroller "PIC16F628".
The serial communication RS232 is level converted by an integrated circuit MAX232.
The power is controlled by a traditional regulated power supply.

What is a thermistor?

A thermistor is a type of resistor with resistance varying according to its temperature.
It is a sensor used to measure temperature in controlling any process

What is a CNC mill machine?

A CNC mill machine is an engraving machine that execute a code named Gerber code or G code.
A G-code is something like coordinate in X,Y,Z.
Any bitmap or jpeg photo could be converted to G code in its grayscale format.....
To make a CNC mill machine you need 5 things : stepper motors with the specified torque, stepper motor drivers(prefreably microstep driver but it is expensive) , paralle port driver circuit, power supply from old pc, a mechanism of the machine (could be find in ebay) ,a CNC mill software like Mach3 or KCAM .
Any electronic circuit could be made by CNC machine.

What is a ICSP?

The "ICSP" stand for in circuit serial programming ;that circuit is integrated inside some of pic microcontrollers (mainly new chips) ;that function lets you to test the code you wrote with your microcontroller attached to your development board. No need to extract your mcu every time from development board and put it in a programmer to program the new firmware..That process happens and the "pic" is installed in the same development board...
I tested the "K128" icsp and it is ok .......

K128 usb programmer

JDM programmer is not stable with PIC18FXX family and that may be noticed by expert programmer ...so I decided to buy a usb programmer ;i purchased a usb programmer board and its name is K128 board ...the link for it http://www.kitsrus.com/pic.html ;that programmer is based on a chip named FT232 and that chip is a buffer that store data from usb and prepare them serially to be send to the microcontroller ;we can say it is a usb to serial converter ...
Programming is fast and easy and no pain in verification process ;it is tested by me for PIC18F452 and PIC16F628,PIC16F676 and it is very good
