It honestly takes all my focus and concentration to remember the signals quickly. That's the look of 100% dedication to a silly task!

I am curious to know how far you take this in terms of it becoming second nature. As in, maybe after days and weeks of practice, you can type stuff effortlessly ?

How far away from effortless mastery are you?

It's always going to be plenty of physical effort! In terms of the mental overhead: there are some letters/motions like R, F, D that just feel second-nature already from lots of practice and more 'obvious' positions, but I still have to think about most of them. A few letters still trip me up, like remembering M versus S (mirror images). I'd love to find a seasoned signalman to get their take.

Makes sense.

I find your project incredibly cool. And your video is awesome. Well done!
