**Edit:**Many people have said that this IC was posted
before it should have been, and I now agree. I am currently
very busy, so I am going to make a new post when I am able
to flesh out my idea so that people have a better idea of
the keyboard that I’m trying to make.
Intro
Hey all! I’m Rocky5232. Just over a year ago, I found
out about the mechanical keyboard community, and now I’m
hooked. One thing that I would have loved to see when I
first found out about this was more budget options as there
are only a few, and stock is always hard to find. So,
keeping that in mind, I decided to design my own
keyboard.
Layout
Here’s the
layout that I’ve decided on for this board.
As you can see, it’s a 45% board with full-size
modifiers. My reasoning for this layout is that 40% boards
look great, but their functionality is severely limited,
especially because of their lack of arrow keys, which is
also a problem that 60% keyboards have. I wanted something
that was similarly compact to a 40%, as I often don’t need
the number row, but is also usable for typing. With this
layout, you have the best of both worlds: a nice compact
keyboard along with arrow keys. I also decided to keep all
the modifier keys full-size, as I couldn’t get them smaller
without the need for an extra set of keycaps.
In
addition, here’s a picture of the plate CAD file that I am
currently planning to use. Keep in mind that it is very
likely to be changed throughout my prototyping.
Physical Design
The keyboard
will be a sandwich-style board with FR4 for the plate and
base and it’ll be held together by standoffs. My current
design has a slight bezel on all edges, but, depending on
what the prototypes look like, I may switch to a design with
minimal bezel.
PCB
The PCB will
be a blank PCB with no SMD parts, and those who buy it will
need to solder on diodes themselves. It’ll also use a
microcontroller which will most likely be a Teensy 2.0 or a
Pro Micro.
Timeline/Interest Form
Currently, I’ve got a PCB design that should work,
and I am ready to order prototypes to test it out. However,
I want to wait to see whether people would be interested in
this or not, so I am holding off on ordering them. There are
a few changes that I want to make to the current PCB design
as well, so it may take a few prototypes for me to be ready
to put this into the GB stage. It would be really helpful to
me if anyone interested could fill out the interest form as
it would tell me whether I should continue this project.
