I built my own Corne keyboard around six months ago, in July. I have been using it ever since. Although I am no expert on split keyboards, I accumulated a fair amount of observations during this whole process. I thought that if I wrote down my experiences, they might still be of interest to people who are considering whether to try a split keyboard. Or, if they are already using one, maybe they can also benefit from some of the tricks that helped me a lot. So, here it is: a blog post about how and why I built my own Corne keyboard, the things I learned and applied to improve my ergonomics over the last 6 months.
