Hey Geekhack,
this is a small keyboard we like
to refer to as mini980.
Let’s look at the layout
first:
Wired
BLE
First of all, this is a 74 keys keyboard, based on
layout 980 but some different, such as the key; and next to
L,changed to the Shift + K and Shift+L, and the [] key next
to P has been reduced to Shift +(the key below BS).then 6.25
spacebar spit to 2.75 U+2.25 U，the purpose of the spacebar
modification is not to need to buy a big set of keycaps, the
second is to be able to add a custom key for this
keyboard
Next, look into the structural features,
Gasket mount, it involves a 1.5mm thick PC plate with
a rubber o-ring between the plate and PCB, we add a o-ring
gasket as above pic. It will also use 2.5mm poron tabs for
the plate. This should help with achieving a softer typing
feeling，We plan to make both Bluetooth and wired versions
of the pcb.

Changes:
Extreme75% first
prototype typing experience was not good, because we
designed is 4.75 mm PC plate, the advantages of the plate is
a good support, the keyboard will feel very full, but there
is no soft in gasket feel.
So after a second of
entanglement, we decided to revise the drawing to make a new
prototype, We kept making prototypes until we were
satisfied.
- The plate thickness was 4.75mm in the first version which was too thick, because the hard type feeling, we changed the plate thickness 1.5mm in the new version. The benefits of doing this are known to increase flexibility and soft typing.
- Added Bluetooth
- We changed the weight design to be more thematic
-
Added Flex cuts to the pcb to help with the typing
experience
