Hello,
thanks all for your kind words.
I must admit that it is not the first time I’ve built my CW keyer. I developed a lot of models along the last decade, ranging from poor to master performance.
You know, to gain skillness you need to practice. Improving is a question of trial and error.
I add here below some pics of my old models.
I think my last piece (the one on the video up in the thread) is the best one I did.
If I could just produce them in batches I’d love to share it with you, but to be honest working teaching maths in my high school is enough by now… I’m looking forward to retire but it is still too far, hi.
VY 73 and for sure we well meet on air using this paddle!

Vertical key, my first wooden key. A lot noisy!!
My first Iambic with paper clips. I had a lot of burn with it the first year of CW operation due to RF coupling back to the shack!!
A single lever iambic I used briefly when I started activating for SOTA, back in 2011.
I like the yelllow electric guitar picks on it. And it saved me from burn!
A new concept that never worked right: the two push button iambic. The touch is too hard, although finding the proper buttons with less spring force could be very interesting. The transparent cover case comes from a Mini DV film.
This one is funny. I salvaged an old PC keyboard and cut 2 tracks from under the keyboard. As for the previous iambic is a vertical tapping system. It only works intermittent… Nice piece of junk.
Following the same principle of the previous one, this is my Micro keyer. It is always in my rucksack as a backup key just in case the main one refuses to work.
It was widely described in this other thread:
Let’s close the listing, I don’t want to be boring…
Did I mention so far I never used a commercial key up in the mountains?
95% of all my activation were done with the next homebrew Iambic. I will keep at home from now on…
It is a bit bigger and with my new mini paddle I don’t need it.
It will have a space in my shack now:
73 es CU.
