To use on the left side of the keyboard. + + +### Layout designed +![Keyboard layout](Keyboard layout.jpg) + +This layout avoids having 2 unit wide buttons, which would interfere with the column sliding mechanism. +Instead these buttons are moved to 2 thumb clusters. Which i I'm eager to try out. + + +### Prototype pile +![Prototype pile](Prototype pile.jpg) + +Here's the pile of prototypes it took to get a satisfying and functional mechanism and keycaps. + + +### Module wired + +![Module wired top](Module wired top.jpg) +![Module wired bottom](Module wired bottom.jpg) + +Soldered up the first module. I used stranded wire due to metal fatigue. This methodology seems to be feasible. +I'm going to add pin header connectors to connect it to the board, so it can be disconnected and the module removed. +Spanning the top is gonna be a prototype board PCB with all the diodes, connectors for modules, DIP28 GPIO expander and +the TRRS headphone jack. + + +### Modules for left side printed +![Coulumns modules for left side WIP](Coulumns modules for left side WIP.jpg) + +Done printing and cleaning up all the modules for the left side. + +![Left side modules in base top](Left side modules in base top.jpg) +![Left side modules in base bottom](Left side modules in base bottom.jpg) + +Printed the bottom for the left side it unfortunately bent slightly when the modules were put in place, +even tho i was patient letting it cool down after printing. I held it over the stove, and counter bend it. +Then placed it on a flat surface. Which fixed the curve. + +![Left side wiring diagram](Left side wiring diagram.jpg) + +Planned out the circuit diagram for the left side of the keyboard, everything fit really nicely. +I'm excited to make it a reality. The top features pin headers for each sliding module. Which has 6 pins, 1 for the +column, and 5 for the rows. The rows are connected to the diodes, which bridge the gap to their respective colored bus +bars on the bottom side. Which forms a natural ╲ ╲ ╲ ╲ ╲ pattern. The columns have busbars on the bottom left side. +Both bus bar clusters are terminated in 2 flex cable connections, one for the GPIO expander chip, and one for a male pin +header for testing and debugging, it's also pin compatible with my old keyboard, allowing me to do an agile partial +goal, and get success feeling of trying it out, motivating me to keep working, and getting to test it +before i add to many variables and unknowns, which could lead to multiple failure points, +making me have to debug multiple possible error sources at the same time. There's 2 rows of connection points next to +the debug connector, which is a fine place to extend the connection on to thumb cluster module, which differs because it +has the diodes on the module as opposed to on the circuit board. It has 1 pin for the row, and the rest for the columns. +Because it's wired up like it was a row at the bottom of the keyboard. Finally the headphone jack fits in the top +right corner, pointing upwards, since there's already going to be the cables from the sliding modules looping that way. + + +### Circuit board initial test + +![Circuit board painted](Circuit board painted.jpg) +![Circuit initial test](Circuit initial test.jpg) + +Painted the circuit board, to indicate where the busbars on the bottom are routed. +Wired up a test setup to test the first 4x4 buttons, and it works, yay ^-^ + +![Left side working prototype](Left side working prototype.jpg) + +## Full stop +So up to this point, i had the intention of making this into a full hand wired keyboard. +But I don't like how the wires at the top ended up looking, +so I've chosen to cut my losses and use my prototype to decide how I want the offsets to be, +and as a test bed to remove my last few unknowns, namely, thumb cluster and I/O expander chip. +I should have cut more corners, to test the core concept, before spending time, on the niceties. \ No newline at end of file diff --git a/Custom keyboard/3d_printed_keycap.jpg b/Custom keyboard/3d_printed_keycap.jpg new file mode 100644 index 0000000..ccc60b1 Binary files /dev/null and b/Custom keyboard/3d_printed_keycap.jpg differ diff --git a/Custom keyboard/3d_printed_switch_plate_test.jpg b/Custom keyboard/3d_printed_switch_plate_test.jpg new file mode 100644 index 0000000..e081ea1 Binary files /dev/null and b/Custom keyboard/3d_printed_switch_plate_test.jpg differ diff --git a/Custom keyboard/Thumbnail.jpg b/Custom keyboard/Thumbnail.jpg new file mode 100644 index 0000000..e3f3f25 Binary files /dev/null and b/Custom keyboard/Thumbnail.jpg differ diff --git a/Custom keyboard/colemak_keyboard_layout.jpg b/Custom keyboard/colemak_keyboard_layout.jpg new file mode 100644 index 0000000..e593bcc Binary files /dev/null and b/Custom keyboard/colemak_keyboard_layout.jpg differ diff --git a/Custom keyboard/connector.jpg b/Custom keyboard/connector.jpg new file mode 100644 index 0000000..c787972 Binary files /dev/null and b/Custom keyboard/connector.jpg differ diff --git a/Custom keyboard/index.md b/Custom keyboard/index.md new file mode 100644 index 0000000..2a3c85d --- /dev/null +++ b/Custom keyboard/index.md @@ -0,0 +1,266 @@ +--- +description: "Custom split ortholinear 83 key mechanical keyboard with rollerball mouse" +created: 2023-10-23 +--- + +![Layout](main.jpg) + +## Links +- [git.node5.net -

This will come back to haunt me later. + +### Keycaps +Found [this](https://www.thingiverse.com/thing:2879386) design i liked, +but i encoundered a problem with it, it snagged when pressing down. So i +[modified the design in FreeCAD as an STL](https://www.youtube.com/watch?v=HbtKFmz5p00) +, as importing it as openSCAD and then modifying gave me issues. +It now has a slope along the long side of the key switch rectangle. + +![Keycap modification](keycap_modification.jpg) +![Keycap modification printed](keycap_modification_printed.jpg) + +The 2 unit wide keys can be made in +[PrusaSlicer](https://www.prusa3d.com/page/prusaslicer_424/) by cutting it into +parts and scaling only the desired part in the desired dimension. +The homing indicator, can also simply be made in PrusaSlicer. + +When printing, place the keycaps sideways on the build plate, as to use the +dimension with the best resulution in FDM printing (Set layer height to the +smallest possible). And make sure the top parts of the keycaps are facing away +from each other, if printing multiple, to avoid stringing, bumps and other +artifacts. + +The keycaps still require quite a lot of cleanup, as there's some drop in the +stem connector, and some cutting and filing is needed on the side of the stem +where the support was. + +### Wiring +![Matrix wiring](matrix_wiring.png) + +This overview was made with [VIA](https://www.caniusevia.com/) + +The column wires can be managed by routing them under the diodes from the rows. + +![Left side testing](left_side_testing.jpg) + +I'd recomend staring with wiring a 3x3 matrix and connecting that on a +breadboard to your microcontroller, and try +[building the firmware](#firmware-build).

Set aside a weekend for learning where the +keys are, and be prepared to be frustrated at typing at 5 wpm, and slowly +working up from there. +It's a bit unfortunate that I'm changing multiple variables at the same time, +Namely learning touch typing, at the same time as i switch to colemak +and an ortholinear layout. Therefore i will not know which impact each has on +percieved finger health and typing speed. + +Also small rant about the legacy typewriter layout that sadly is the norm now +adays. How are you supposed to twist and contort your middle finger to reach +from D on the home row to C below when your hands are so close together that +they aren't straight. It feels more natural for my pointing finger to reach the +C button, because it aligns with the direction my hands are pointing. + +## Retrospective / Ideas for a version 2 + +### Work methodologies +Before starting a handwired keyboard project know that: + + - It's very labor intensive + - Hand wiring will take a long time especially if you make a split keeb, and choose to not use I²C between the halves. + - When prototyping something it's an itterative process, + which 3D printing plays very well into, as you can rapidly prototype, test ideas, and modify your design. + + +### Scrolling / volume rollers +Scrolling and adjusting volume with the trackball works great. +It would be awesome to explore this concept more, +by having a dedicated rotary encoder for it, perhaps two, +for quick onehanded volume adjustment, without holding the modifier (FN), +which is on the other side of the keyboard. + +### Device specific LED indicators +The LED in the pimoroni trackball works great to indicate which mode it's in. +So having dedicated LEDs for each device, +to indicate which mode it's in is a great to have. + +### LED indicators +They work great as a layer indicator. +Another idea is to add a photo resistor to dimm them in low ambient. + +### Pimoroni trackball +It's a really nifty little device, glad i tried it out, +but it's not precise enough for my taste. +It might be the QMK implementation (which already existed, which is nice), +It might be a hardware thing. Not sure, haven't read raw device output, +i assume default QMK settings are sane. +But next time around i want to try a different pointing device, +perhaps a ThinkPad trackpoint. + +### Connector / cable / wiring management +It worked fine for the time, since i had plenty of time to work on it now, +and didn't have to wait for components. +The process of hand wiring is labor intensive and tedious work. +Managing the wiring in a PCB and using chips in each half, +with standard cables would be preferable. +Then it's also possible to use longer cables to position the keyboard on either +side of a laptop, when using it on the go. +Taking up less space in one dimmension, but more in another, +by not having to move the laptop as far back, giving you flexibility. + +### Touch typing colorway +The keycaps can be colored to indicate which finger should be used. +This could also be done in software, if one chooses to add per key LEDs. + +### Standoffs on switch plate +Designing the standoffs into the switch plate might be desirable, since it +can make the cable wiring a bit easier, + +### Macro recording indicator +QMK Has the ability to record +[Dynamic macros](https://docs.qmk.fm/#/feature_dynamic_macros) +It would be cool to indicate the recording of such, by blinking the main +indicator LED red, this requires the ability to get
