<h1>New Keyboard!</h1>
|
||||
<a href="#fine_here_it_is">tl;dr show me the board</a>
|
||||
<p>
|
||||
Throughout the past few years I've hopped from keyboard to keyboard
|
||||
initally as a need for something to type on, but eventually as an obession
|
||||
with the sound and feel which to this day I cannot shake.
|
||||
</p>
|
||||
<h2>Keyboard #1</h2>
|
||||
<p>
|
||||
I started on a Razer Cynosa Chroma which as far as I can tell is no longer
|
||||
for sale. But for the sake of context you should know that it's a 100%
|
||||
membrane keyboard with per key backlighting. For a starter keyboard it was
|
||||
fine, but looking back any old office keyboard would've worked and the
|
||||
$40(?) that I spent on it was not worth it. But who cares, lets go to the
|
||||
next keyboard!
|
||||
</p>
|
||||
<h2>Keyboard #2</h2>
|
||||
<p>
|
||||
After being pushed by a friend who was <s>obsessed</s> interested in
|
||||
keyboards I finally took the plunge and built my first custom keyboard.
|
||||
This keyboard was a what I thought would be best after using a membrane
|
||||
for over two years (I had very little clue what I was doing). I ended up
|
||||
choosing a TKL board called the NINJA87BT which came with gateron milky
|
||||
yellow switches. This may not sound custom, but then I went and ordered
|
||||
some very very expensive switches called Helios v2s which are very quiet
|
||||
and so soft to type on. I also bought some keycaps with legends printed
|
||||
on the side nothing too expensive, but very nice to look at. Because this
|
||||
was my first board I had no clue what I was doing and I ended up spending
|
||||
around $300...
|
||||
</p>
|
||||
<h2>Keyboard #3</h2>
|
||||
<p>
|
||||
I started thinking about the future and how I really needed to take care
|
||||
of the hands that I use every day for programming. Though I wanted to go
|
||||
fully ergonomic, like where I'm at now, I chose to pace myself and decided
|
||||
to go with a UHK 60v2. It was expensive, but it promised something
|
||||
spectacular: a split keyboard without the ortho keywells and qmk
|
||||
configuration of my current keyboard which would've been very hard to
|
||||
switch to coming from a normal TKL. Instead of sticking with the cherry
|
||||
reds it came with I put my Helios in (because they are still the best
|
||||
switches I've ever felt). While this board was not nearly as custom as my
|
||||
last I was able to enjoy it much more knowing I was not going to get
|
||||
carpel tunnel halfway through my life.
|
||||
</p>
|
||||
<p>
|
||||
I ended up using this board for about a year and a half until around mid
|
||||
July of 2025 when I updated the firmware for the first time since getting
|
||||
the board and it caused the keyboard to start crashing every once in a
|
||||
while. I tried to roll back to the version I was using before, but my
|
||||
configuration wasn't able to migrate back. So I decided it was time to
|
||||
move on to the keyboard I'd been dreaming of making.
|
||||
</p>
|
||||
<h2>Keyboard #4 (my current one)</h2>
|
||||
<p>
|
||||
The keyboard I've been typing this post on is a dactyl manuform 4x5, and
|
||||
It's my first truly hand built keyboard. I 3d printed the case, sanded,
|
||||
primed, painted (although it did not hide the layer lines very well), and
|
||||
wired. Wiring was a bit tricky but thanks to the pictures in the
|
||||
<a href="https://github.com/abstracthat/dactyl-manuform">github repo</a>
|
||||
I was able to do it without too much trouble.
|
||||

||||

||||

|
||||
<p>
|
||||
After finishing the wiring, which took around 12 hours, I tried to flash
|
||||
qmk to both halves. At which point realized that the right half had the
|
||||
rows wired to the arduino pro micro in reverse order. After fixing the
|
||||
slight hiccup I flashed and viola a working keyboard. I then put on some
|
||||
black legend-less keycaps, and here is the final(ish) result:
|
||||
</p>
|
||||
<img id="fine_here_it_is" src="/blog/New-Keyboard!/pics/final-ish.jpg">
|
||||
<p>
|
||||
The ish in final(ish) is because I've yet to add a baseplate which would
|
||||
add some much needed weight so the halves doesn't slide across my desk,
|
||||
but for now I'm happy with it.
|
||||

|
||||
<h3>Build your own</h3>
|
||||
<p>
|
||||
Incase you're reading this in the hopes of some tips for building your
|
||||
own here they are:
|
||||
<ul>
|
||||
<li>get the model for the keyboard from
|
||||
<a href="https://ryanis.cool/dactyl/#manuform">ryanis.cool/dactyl/#manuform</a></li>
|
||||
<li>when wiring your keyboard try and make the wires going from the
|
||||
rows/columns around 1.5-2x longer than they need to be that way you
|
||||
don't snap when you're fiddling around in there</li>
|
||||
<li>if you want to get rid of layer lines look into acetone dipping your
|
||||
print, I only learned about this after showing my fully wired board
|
||||
to a friend otherwise I would've done it</li>
|
||||
</ul>
|
||||
</p>
|
||||
<p>
|
||||
When it comes to using my keyboard it's setup for typing as that's what I
|
||||
do on it it most of the time, however when I play games things get a bit
|
||||
tricky. For games where I can remap the keys I shift every key over by one
|
||||
except for the keys on the bottom row, and then I set the sprint key as a.
|
||||
For the games where I can't remap the keys... I just stop playing them.
|
||||
If I had more of an interest in gaming I would've gone with the 4x6 as
|
||||
6 more keys it offeres could've been really nice.
|
||||
</p>
|
||||
<p>
|
||||
For those curious about the specs: I decided on a rj9 port mainly because
|
||||
I like the look of them over the TRRS cables everyone seems to be using
|
||||
nowadays. For the pro micro I went with the cheapest one I could find
|
||||
with a usb-c port, you can't really go wrong here. As for the actual
|
||||
layout my qmk config is below incase you really wanna know how I type:

<h1>Serializing data in C</h1>
|
||||
<p>
|
||||
I've started work on a new project! The project in question is one that
|
||||
I have wanted to tackle for a long time but did not have the courage to
|
||||
do so. However at long last it is time...
|
||||
</p>
|
||||
<p>
|
||||
time to get funky...
|
||||
</p>
|
||||
<p>
|
||||
I'm writing a music player, and not one that simply plays music like
|
||||
spotify. This music player falls more inline with MPD in which it's a
|
||||
daemon running in the background playing the music and clients may
|
||||
communicate with it to tell it what to play when and the likes.
|
||||
</p>
|
||||
<p>
|
||||
Currently I'm at that very important part in which the daemon needs to
|
||||
communicate to clients via a protocol *fancy*, and to do so I have decided
|
||||
to go with a socket that way <i>in theory</i> I can control my daemon from
|
||||
other devices on the network. With the communication method decided I now
|
||||
have to define what data goes between devices. At the current moment I've
|
||||
settled on an enum for different signals.

As for how I actually transmit the signals, I've settled on a format which
|
||||
defaults to 42 bytes of data being sent with the option to send more by
|
||||
setting the 41st-42nd bytes to a uint16 containing the additional number
|
||||
of bytes being sent.

I'm not sure how this compares to other protocols used to transmit data,
|
||||
but I'm quite proud of how I've laid this out.
|
||||
</p>
|
||||
<p>
|
||||
Moving on to actual the point of this article: serialization. For the sake
|
||||
of useablilty I've defined a datatype which models our payload which you
|
||||
can see here:

|

<p>
|

I've provided this so that you don't have to deal with manually setting
|
||||
the size of the data that you pass into the object, although (if you so
|
||||
choose) you may easily override it.
|

|
||||
<h2>Serializing</h2>
|
||||
<p>
|
||||
Now that we've gone over the interface for interacting with the payload
|
||||
let's get to the intersting stage in which we get the data ready for
|
||||
launch.

As you may have noticed in the code snippet above libmoo_serialize_data is
|
||||
a function that takes in a pre-allocated payload, and the data to
|
||||
serialize. I've opted to allow the user to allocate space for the payload
|
||||
if they determine that they know what they're doing incase my dumb
|
||||
function is too generous. Moving onto the body of the function you'll see
|
||||
an unfamiliar function called mempcpy which is a macro for copying data
|
||||
into the payload. This macro takes in the same arguments as memcpy (dest,
|
||||
src, size), but in addition it increments dest by size so I can append
|
||||
data to the payload without making this code horrible to read.
|
||||
</p>
|
||||
<p>
|
||||
In earlier stages of development I didn't actually return the size of the
|
||||
resulting payload, thinking that I could just strlen it. This was a rookie
|
||||
mistake. Because I've included extra space (bytes 8-31) when you run
|
||||
strlen on any payload it results in 5 (the length of the version string).
|
||||
After finding this out I decided that I do actually want to send more
|
||||
than the version information, and so now libmoo_serialize_data returns a
|
||||
size_t continaing the number of bytes that have been serialized.
|
||||
</p>
|
||||
<h2>Deserializing</h2>
|
||||
<p>
|
||||
Now that we've serialized and <i>presumably</i> sent the data to a client
|
||||
we need to do the magic part which completes this transaction:
|
||||
deserialization.
|
||||
</p>
|
||||
<p>
|
||||
Below is my method of deserializing the data. It's pretty much the
|
||||
opposite of the serialization function with the key exception that we
|
||||
need to do some validation. <i>Which I haven't implemented yet.</i>

<p>
|

And that's kinda it just like with the mempcpy macro I've made a memscpy
|
||||
macro which increments the src by the size of the data to make reading
|
||||
the data easy.

<h1>New Keyboard!</h1>
|
||||
<a href="#fine_here_it_is">tl;dr show me the board</a>
|
||||
<p>
|
||||
Throughout the past few years I've hopped from keyboard to keyboard
|
||||
initally as a need for something to type on, but eventually as an obession
|
||||
with the sound and feel which to this day I cannot shake.
|
||||
</p>
|
||||
<h2>Keyboard #1</h2>
|
||||
<p>
|
||||
I started on a Razer Cynosa Chroma which as far as I can tell is no longer
|
||||
for sale. But for the sake of context you should know that it's a 100%
|
||||
membrane keyboard with per key backlighting. For a starter keyboard it was
|
||||
fine, but looking back any old office keyboard would've worked and the
|
||||
$40(?) that I spent on it was not worth it. But who cares, lets go to the
|
||||
next keyboard!
|
||||
</p>
|
||||
<h2>Keyboard #2</h2>
|
||||
<p>
|
||||
After being pushed by a friend who was <s>obsessed</s> interested in
|
||||
keyboards I finally took the plunge and built my first custom keyboard.
|
||||
This keyboard was a what I thought would be best after using a membrane
|
||||
for over two years (I had very little clue what I was doing). I ended up
|
||||
choosing a TKL board called the NINJA87BT which came with gateron milky
|
||||
yellow switches. This may not sound custom, but then I went and ordered
|
||||
some very very expensive switches called Helios v2s which are very quiet
|
||||
and so soft to type on. I also bought some keycaps with legends printed
|
||||
on the side nothing too expensive, but very nice to look at. Because this
|
||||
was my first board I had no clue what I was doing and I ended up spending
|
||||
around $300...
|
||||
</p>
|
||||
<h2>Keyboard #3</h2>
|
||||
<p>
|
||||
I started thinking about the future and how I really needed to take care
|
||||
of the hands that I use every day for programming. Though I wanted to go
|
||||
fully ergonomic, like where I'm at now, I chose to pace myself and decided
|
||||
to go with a UHK 60v2. It was expensive, but it promised something
|
||||
spectacular: a split keyboard without the ortho keywells and qmk
|
||||
configuration of my current keyboard which would've been very hard to
|
||||
switch to coming from a normal TKL. Instead of sticking with the cherry
|
||||
reds it came with I put my Helios in (because they are still the best
|
||||
switches I've ever felt). While this board was not nearly as custom as my
|
||||
last I was able to enjoy it much more knowing I was not going to get
|
||||
carpel tunnel halfway through my life.
|
||||
</p>
|
||||
<p>
|
||||
I ended up using this board for about a year and a half until around mid
|
||||
July of 2025 when I updated the firmware for the first time since getting
|
||||
the board and it caused the keyboard to start crashing every once in a
|
||||
while. I tried to roll back to the version I was using before, but my
|
||||
configuration wasn't able to migrate back. So I decided it was time to
|
||||
move on to the keyboard I'd been dreaming of making.
|
||||
</p>
|
||||
<h2>Keyboard #4 (my current one)</h2>
|
||||
<p>
|
||||
The keyboard I've been typing this post on is a dactyl manuform 4x5, and
|
||||
It's my first truly hand built keyboard. I 3d printed the case, sanded,
|
||||
primed, painted (although it did not hide the layer lines very well), and
|
||||
wired. Wiring was a bit tricky but thanks to the pictures in the
|
||||
<a href="https://github.com/abstracthat/dactyl-manuform">github repo</a>
|
||||
I was able to do it without too much trouble.
|
||||
</p>
|
||||
<img src="/blog/New-Keyboard!/pics/sanded.jpg">
|
||||
<img src="/blog/New-Keyboard!/pics/wiring.jpg">
|
||||
<p>
|
||||
After finishing the wiring, which took around 12 hours, I tried to flash
|
||||
qmk to both halves. At which point realized that the right half had the
|
||||
rows wired to the arduino pro micro in reverse order. After fixing the
|
||||
slight hiccup I flashed and viola a working keyboard. I then put on some
|
||||
black legend-less keycaps, and here is the final(ish) result:
|
||||
</p>
|
||||
<img id="fine_here_it_is" src="/blog/New-Keyboard!/pics/final-ish.jpg">
|
||||
<p>
|
||||
The ish in final(ish) is because I've yet to add a baseplate which would
|
||||
add some much needed weight so the halves doesn't slide across my desk,
|
||||
but for now I'm happy with it.
|
||||
</p>
|
||||
<h3>Build your own</h3>
|
||||
<p>
|
||||
Incase you're reading this in the hopes of some tips for building your
|
||||
own here they are:
|
||||
<ul>
|
||||
<li>get the model for the keyboard from
|
||||
<a href="https://ryanis.cool/dactyl/#manuform">ryanis.cool/dactyl/#manuform</a></li>
|
||||
<li>when wiring your keyboard try and make the wires going from the
|
||||
rows/columns around 1.5-2x longer than they need to be that way you
|
||||
don't snap when you're fiddling around in there</li>
|
||||
<li>if you want to get rid of layer lines look into acetone dipping your
|
||||
print, I only learned about this after showing my fully wired board
|
||||
to a friend otherwise I would've done it</li>
|
||||
</ul>
|
||||
</p>
|
||||
<p>
|
||||
When it comes to using my keyboard it's setup for typing as that's what I
|
||||
do on it it most of the time, however when I play games things get a bit
|
||||
tricky. For games where I can remap the keys I shift every key over by one
|
||||
except for the keys on the bottom row, and then I set the sprint key as a.
|
||||
For the games where I can't remap the keys... I just stop playing them.
|
||||
If I had more of an interest in gaming I would've gone with the 4x6 as
|
||||
6 more keys it offeres could've been really nice.
|
||||
</p>
|
||||
<p>
|
||||
For those curious about the specs: I decided on a rj9 port mainly because
|
||||
I like the look of them over the TRRS cables everyone seems to be using
|
||||
nowadays. For the pro micro I went with the cheapest one I could find
|
||||
with a usb-c port, you can't really go wrong here. As for the actual
|
||||
layout my qmk config is below incase you really wanna know how I type:

Welcome to my website. I do a bunch of coding, I try to lean towards
|
||||
lower level languages (mostly C) as I find it more fun when there's a
|
||||
challenge. As for the content of this website: I put blog posts up
|
||||
when I've got something interesting to talk about and host my own git
|
||||
server with stuff I make (you can find the things I'm proud of below).
