Ergonomic, split and other weird keyboards

Rules

Keep it ergo

Posts must be of/about keyboards that have a clear delineation between the left and right halves of the keyboard, column stagger, or both. This includes one-handed (one half doesn't exist, what clearer delineation is that!?)

i.e. no regular non-split¹ row-stagger and no non-split¹ ortholinear²

¹ split meaning a separation of the halves, whether fixed in place or entirely separate, both are fine.
² ortholinear meaning keys layed out in a grid

Looks really clean! How do the RJ11s compare to the RJ45s in the cheapino? Could you get away with doing a single microcontroller with them?

[–] pinsl 3 points 1 year ago* (last edited 1 year ago) (1 children)

The connector that the cheapino uses (8P8C) has eight pins while the 4P4C connector that I use has four pins. The cheapino uses eight wires to connect its halfs. So no, you cannot just use the 4P4C connector instead of the 8P8C connector.

Note that the terms RJ11 and RJ45 only specify the type of connector but don't how much pins it has. Use the terms 4P4C and 8P8C instead.

Thanks for the explanation! Yeah, I misremembered what I read about the cheapino not using all of its 8P8C wires (it uses 7 out of 8), but that makes sense.
