Inland MK-47

Cheap QMK ortho-linear keyboard

This keyboard is an amazing low commitment introduction to ortho-linear keyboards. I’m glad they included QMK support, because in my opinion, any keyboard smaller than a TKL should use QMK

It’s also hotswap!

Mods applied

Of course I had to mod the keyboard!

  • Swapped the stems of the original switches with UHMWPE stems
    • The stock switches are linear Huano Reds and the stems fit really well
  • Add silencing foam underneath the PCB
  • Lubed the stock stabilizer with Kryotox 205g0

Meh keycaps

I wish they sold a version with blank keycaps.

Ortholinear keyboards are very personal and the location of the legends that their keycaps provided don’t make much sense to me.

I don’t usually look down on my keyboard but I like knowing that the legend of the key that I pressed corresponds to the action that it does.

Fortunately, I had a ton of extra keycaps from a time when I was spending all of my income on anything related to keyboards (not my smartest investment).

Keymap

I took inspiration from the Miryoku keymap

Holding home row keys to act as modifiers is brilliant!

I wish I had known about this keymap when I used to own multiple 40% keyboards.

For reference, my keymap in its entirety:

// Tap-hold modifiers
#define LSHTP LSFT_T(KC_F)
#define LSTAP LCMD_T(KC_D)
#define LMTAP LOPT_T(KC_S)
#define LCTAP LCTL_T(KC_A)

#define RSHTP RSFT_T(KC_J)
#define RSTAP RCMD_T(KC_K)
#define RMTAP ROPT_T(KC_L)
#define RCTAP RCTL_T(KC_SCLN)

Comfort

Nonsplit ortholinear keyboards feel a little too cramped for my taste and I’m a pretty compact guy.

I start to feel a bit of shoulder discomfort if I keep my digits on the keys while I think.

Conclusion

For its price point, it’s a good introduction to the world of ortholinear keyboards and finding your perfect keymap. I honestly can’t use it as a daily driver because of the mental overhead involved when I have to figure out where I mapped rarely used keys and the discomfort I feel on my shoulders over time.
