Yo freak dude, we would help you but we are busy fighting amongst 
ourselves to see who would be most privileged to help. This could take a 
while so please don't feel like you have to wait for us to tell you how 
to do it. I am sure that by the time you have gotten the project off the 
ground that we will be there to catch you if you should fall.

thanx dude... 
but i m still a beginner in AVR.. got really freaked out coz cant get anythin useful... still no idea wat a 
security dongle is n how to construct it using AT MEGA16 or TINY26 assembly..

If you have no idea and you haven't even googled and yet you want to 
tackle the advanced stuff, then who ends up doing all the work? I 
respond to posts in many other groups and your request is not at all 
uncommon but put yourself in our place. Yes, we may know how to do it, 
and yes we could do it for you IF we had nothing else to do AND we were 
willing. The end result? You reap the fruits of someone else's labor and 
you have not learned anything except that you can get other people to do 
your work for you.

"Feed a man a fish and you have fed him for a day. Teach a man to fish 
and you have fed him for a lifetime."

You sound like a student and as such are being taught. We are like 
fellow fishermen, we can see what you may be doing wrong and we could 
offer you a few pointers but it is up to you to do your own work.

I always recommend simple projects to start out and build on them. When I 
started using AVR's I'd already had quite a bit of experience with PIC's, 
so AVR's weren't that difficult to learn, but I still had some learning to 
do.  The STK-500 is a great tool for this.  Once you've played around with 
the code in the chip they supply that turns on LED's, try writing a 
program to do it via the serial port. 

For more data on different projects you can try, look at the Atmel 
website; there's a lot of application notes, etc. there.  The other 
website to look at is AVRFreaks.

  An additional thought:  don't start out on a proiject where you have 
NO expertise at all.  Not being familiar with a specific
processor family is not a significant imnpediment to completing a 
project.  That, in facvt, is the best way to LEARN a new processor.  But 
taking on a project where you have *NO* background and no informatin at 
all, without doing the fundamental research ahead of time, is just plain 
stupid.

What flags this for me is that you are jumping from just being
introduced to the chips and then into a very specific product that has
very limited applications and is well beyond almost any hobby use.

It seems to me that the learner is looking for what I would call a 
"canonical first project".  In my mind, such a project should have 
certain characteristics and goals:

[]  It should perform a simple, well-defined function that the learner 
is already familiar with.  Ideally, the project should be something 
that even non-technical people can relate to as well.  The 
psychological effect of an uninvolved person seeing the finished 
project and commenting along the lines of "hey, that's cool, you did 
that?" is big boost to a learner.

[]  Information for realising this project should be readily 
available, say, from part manufacturer's websites.

[]  It should be realisable with a minimum of hardware.

[]  It should do something sufficiently useful and non-trivial as to 
justify either keeping the project around, making a better second 
version, or using it as the basis for future projects.

[]  It should force the development of skills.  Actually, all projects 
should be seen as an opportunity to develop or enhance skills.

[]  Ideally, it should be expandable in that you can add more "bells 
and whistles" as the learner's skills improve.

I suggest that the learner start by making a simple time-of-day clock. 
  It fits the list of requirements above, it can also serve as the 
basis for other projects down the line, both in terms of actual code 
and hardware generated, and it is a skill-builder.  It might even make 
a good class project.

An incomplete list of tasks that have to be performed just to show the 
time are:

[]  Getting a correct hardware layout.
[]  Getting the clock oscillator to operate reliably and stably.
[]  Generating one-second events.
[]  Counting those events.
[]  Dispaying those events is a sensible form (i.e. hours, minutes, 
seconds).  Reasonable display options involve directly driving a 
7-segment display of some sort, or perhaps an LCD character module.  I 
would favour the 7-segment display since it would not only involve 
learning how to do a lot of low-level bit-fiddling, but is something 
that can be packaged up and used in other projects.

Improvements include:

[]  Coming up with a method of setting the clock.  In increasing 
complexity, one could use the "two-button" method that most watches 
and clocks use, or one could even set up a keypad or even an actual 
keyboard interface.  All of these can be explored; keypad routines can 
also be packaged up and reused.
[]  Adding an alarm or two.
[]  Adding multiple time zone display.
[]  Adding a calendar.
[]  "Use your imagination".
