My ultimate electric keyer with message memory function

I think I will NOT make anymore regarding electric keyer, because this keyer is the "ultimate" for my purpose. In addition to electric keyer, now the sending message is stored in simple text file inside SD card, meaning no firmware upload required just for message change! (You don't need to use Arduino IDE but just text editor is enough!) Also I added one Morse reception training mode. My personal needs are fully satisfied, and will not make any more! Have fun!
