    I would like to build an embedded system, I have limited experienc
    with an hc11 microcontroller, but I have good c,c++,java,assembl
    skills. I would like to build a hand held electronic dictionary.
    want an lcd screen(2-3 lines) connected to thin "flimsy" keypad
    size of the system approximately 4"x6",and it can be run by batter
    or possibly solar.. and I would like to mass produce these for a
    cheap as possible(under 5 dollars?). That is the final goal. What
    need is guidance as to starting this project. As of right now I hav
    nothing. I do not know what hardware to buy, where to buy it, and ho
    to set it up t
    begin programming on it. I need advice to help get the ball rolling
    any comments or suggestions would be awesome.. I have a breadboard
    would like to buy the minimum amount of hardware necessary, set it u
    and program it on breadboard, then from there convert it into fina
    project. Since this will be acting as a dictionary, I may have up t
    5000 words stored or more..

    You may want to consider looking at Microchip PICS. They are friendly,
    easy to use, simple microcontrollers with relatively inexpensive
    development tools. On top of all of this, you will need access to
    tools, such as an oscilloscope and a logic analyzer, probably as a

    Aside from the microcontroller, to design a system as complex as you
    describe will require a broad understanding of both analog and digital
    electronics. Obviously this is no simple task. I would recommend
    that you start with a book on electronic projects, geared towards your
    present skill level, and work up from there.
