New to arduino - general help for my morse encoder/decoder project

Hello, I have good experience in electronics and smd but not in embedded software.
I would like to build a morse code encoded/decoder using arduino, but I would like to build my own hardware in smd (very space limited). I would like to know the next things please:

  1. Where can I find schematics to build my arduino uno (hackduino?)
  2. Will it be compatible to this board sold on ebay, if I rewuire it? http://www.ebay.com/itm/280946481775?ssPageName=STRK%3AMEBIDX%3AIT&fromMakeTrack=true
  3. Where should I start in programming the thing? (software and libraries?)

Thank you very much

  1. Where can I find schematics to build my arduino uno (hackduino?)

Google "stand alone Arduino".

  1. Will it be compatible to this board sold on ebay, if I rewuire it?

Given that that shield is the same size as an Arduino, I fail to see the benefit of making your own, smaller, Arduino.

  1. Where should I start in programming the thing?

With the Arduino IDE and a clue what it should actually do.

Look for a copy of the May, 2015 CQ magazine. There is an excellent article on a CW keyboard using an Arduino. Links to the software are there and explanation about downloading it. Used a PS2 keyboard.

I built it and after a few software mods, works just fine. Mods were to use a different piezo sounder.

Total waste of time. Yours, mine and everyone else's.

If you want a smaller Arduino module, use a Pro Mini. It is SMD and does not include the USB interface which you do not want for a project that in its final form, does not connect to a PC.
