in 2 /5 /2009 i started to work in my new project ; it's about a single chip Pulse position decoder the aim of this project is to be able to decode the regular RC system signal to use it in my custom remote control system which it is more reliable than the regular commercial PPM/FM hobby RC units , Also i'll be able to use it with FMS or with my previous project receiver (simplex 2) . Project Tasks : 1- decode 6 CH art-tech Remote control signal (complete) . 2- FMS Driver (complete) . 3- (Simplex2) Driver NOT stable yet ( beta ) . 4- PCB (complete) . i did some enchantment to the system i added BNC connector to RF out put which makes it easy to remove the antenna or switch between yagi antenna and monopole antenna the next image shows 433Mhz monopole antenna i designed for this project

the main computer over view field robotics & aeronautics remote control system Abstract :- This paper describes the design and implementation of a powerful, multi purpose programmable remote control system for aeronautics , field robotics or any other remote controlled application .operation systems are available on Embedded C . it's easy to use like any other remote control system . Main computer: It’s based on pic18f4550 microcontroller with high efficiency operation software to give user high and reliable performance. Also with power supervisor unit to be able to detect your battery health to make sure that you never run out of battery during mission. any joystick can be modified to suit design , here iused attack3 pc game joystick Main control unit Features:- *-High speed joystick response (real time delay not even notes). *-Light Weight. *-main computer built with power management unit *-LCD and easy navigation menu. *-Suitable for all aeronautic systems, *-Up to 1.2km w

these pictures shows some of my PCB work , the main problem you'll face when you using toner transfer method is choosing right type of papers , well there is alots of people mentioned about using Inkjet Glossy Paper to do Toner Transfer. It can be done. But it is not easy to remove it after ironing. anyway i have done very successful PCBs using (colorway high glossy photo paper 200 g) the pictures show the result of work double-side PCB

this is my servo driver circuit it base on pic16f877a mcu. it can control of 7 servos , 8 relay and one PWM out put . regards Eng . M .Elamin
