Show HN: Bayleaf - Building a low-profile wireless split keyboard
Hey HN, I built a wireless, split, ultra-low profile keyboard from
scratch called Bayleaf. As a beginner I learned all things
electronics, PCB-building, designing for manufacturing, and many
other hardware-related skills to put this together. This case
study dives into the build process and of course the final result,
hope you enjoy!

|
| The question is: How well? I'm not entirely happy with my QMK
| firmware implementation. Tap-hold is the antithesis of n-key
| rollover; one needs to learn to properly nest key-down, key-
| up events. It's easy to switch from a clarinet (cleanly cover
| holes) to a saxophone (slap pads), but hard switching back.
| And we've all learned to type like we're on a saxophone,
| relying on n-key rollover to cover many sins.
|
| I now use QMK firmware with Hasu controllers for multiple
| Leopold FC660C keyboards with Topre Silent 45g "rubber dome"
| key switches. After trying dozens of mechanical key switches,
| I found that nothing feels like a Topre switch.
|
| And here's the kicker: The physical form factor doesn't
| matter so much if your fingers rarely go far from home row,
| which is what tap/hold facilitates.

|

|
| If you want a 10deg downwards angle on the keyboard
| relative to your forearm and your forearm is 5deg
| upwards, then your keyboard _still_ needs 5deg downward
| relative to your desk. If your desk is so high that your
| forearms are angled up 20deg from the horizontal, then
| something is _extremely_ wrong with your chair /desk
| height.
|
| And your first link supports exactly what I wrote:
|
| > _The natural position of your hands with respect to the
| relative vertical position at the wrist is along the
| plane or below it (i.e. you want the tips of your fingers
| to be at the same height as your wrist or preferably
| slightly lower). When your hand rises above this plane
| (making the hand signal for 'STOP'), this is called
| dorsiflexion or wrist extension. This greatly reduces
| blood flow through the wrist and can quickly cause pain,
| fatigue and numbness. Most keyboards have a 'foot'
| located at the back of the keyboard which is not
| desirable as it creates a positively inclined keyboarding
| surface. Many articulating arms offer the option of a
| negative inclination, which will make the entire work
| surface slope away from you, ensuring that your hands are
| not 'bent' upward at the wrist._
|
| And I don't know why you've added another link about
| sideways mouse slant. That has nothing to do with up-down
| keyboard/arm angle. If there's some relevant sentence in
| it, please quote it, because I can find nothing relevant
| in the publicly available text.
|
| You ask me to "please take your time to read" -- I
| suggest you take the time to re-read your own first link.
| It makes clear there is _no_ situation where a keyboard
| angled upwards (the back of the keyboard elevated) is
| good ergonomics -- exactly what I said.

| In the nav layer. One popular layout of split keyboards is two
