Programmable CW keyer with arduino

CW is a great fun, but operators are lazy... So am I. Bands are so quiet many times, while stations are there, but listening only instead of calling seek you. Propagation is made by stations this time. You never know if the other side can hear you until one of you calls CQ. 
I often work at my desk, where my transceiver is. Leaving the radio on does not disturb me in the work. Automatic keyer can call CQ instead of me I only need to touch the paddles when hearing a coming back station. 

The heart of the gadget is an arduino board, with an Atmel chip. It is so so tiny.
There is no big room inside, only few features, and 9 memories fit in. Memories are located in the non violate part of the memory, so one does not have to be afraid of wearing it out. 

The original project can be found here: https://blog.radioartisan.com/arduino-cw-keyer/

K3NG Jim is a genius! The whole project is amazingly sophisticated and well documented. After reading the page you will have no questions.

My friend HA7MAC Gabor helped me out with some questions and also helped me out with a tiny arduino board. It infected me in a second:)

The board needs only few capacitors, resistors, a led, a piezzo buzzer, and a project box with buttons and connectors.

If you need immediate success, just go ahead and jump on into it!

I will make a smaller, battery powered version as well specially for qrp portable operation. There s touch paddle option available in the software, therefore sensitive paddle is not needed to be carried out to the wood. Only two screws or other metal surfaces needed for it.




Programming and using the keyer is easy and straight-forward. 



I think no more words needed... let's grab the key!
