| # The Dactyl-ManuForm Keyboard | ||
| This is a fork of the [Dactyl](https://github.com/adereth/dactyl-keyboard), a parameterized, split-hand, concave, columnar, ergonomic keyboard. | ||
| # The Dactyl-ManuForm-Mini Keyboard | ||
|
|
||
|  | ||
| This is a fork of the [Dactyl-Manuform](https://github.com/adereth/dactyl-keyboard). | ||
|
|
||
| The main change is that the thumb cluster was adapted from the [ManuForm keyboard](https://github.com/jeffgran/ManuForm) ([geekhack](https://geekhack.org/index.php?topic=46015.0)). The walls were changed to just drop to the floor. The keyboard is paramaterized to allow adjusting the following: | ||
| ## Generating OpenSCAD and STL models | ||
|
|
||
| * Rows: 4 - 6 | ||
| * Columns: 5 and up | ||
| * Row curvature | ||
| * Column curvature | ||
| * Row tilt (tenting) | ||
| * Column tilt | ||
| * Column offsets | ||
| * Height | ||
|
|
||
| I built a 4x5 version (40% size) for myself. The default has a bit more tenting than the Dactyl. See the following model files for configurations that may be most common: | ||
|
|
||
| * [40% size, (4x5)](https://github.com/tshort/dactyl-keyboard/blob/master/things/right-4x5.stl) | ||
| * [60% size, (5x6)](https://github.com/tshort/dactyl-keyboard/blob/master/things/right-5x6.stl) | ||

||
| ### Generating a Design | ||
|
|
||
| **Setting up the Clojure environment** | ||
| * [Install the Clojure runtime](https://clojure.org) | ||
| * [Install the Leiningen project manager](http://leiningen.org/) | ||
| * [Install OpenSCAD](http://www.openscad.org/) | ||
|
|
||
| **Generating the design** | ||
| * Run `lein generate` | ||
| * Run `lein generate` or `lein auto generate` | ||
| * This will regenerate the `things/*.scad` files | ||
| * Use OpenSCAD to open a `.scad` file. | ||
| * Make changes to design, repeat `load-file`, OpenSCAD will watch for changes and rerender. | ||
| * When done, use OpenSCAD to export STL files | ||
|
|
||
| **Tips** | ||
| * Run `lein auto generate` instead of `lein generate` to speed up your workflow. | ||
| * [Some other ways to evaluate the clojure design file](http://stackoverflow.com/a/28213489) | ||
| * [Example designing with clojure](http://adereth.github.io/blog/2014/04/09/3d-printing-with-clojure/) | ||
|
|
||
|
|
||
| ### Printing | ||
| Pregenerated STL files are available in the [things/](things/) directory. | ||
| When a model is generated, it also generates a `.scad` model for a bottom plate. | ||
| This can be exported to a DXF file in OpenSCAD. | ||
| The [things/](things/) directory also has DXF files for the bottom plate. | ||
| When laser cut, some of the inside cuts will need to be removed. | ||
|
|
||
| This model can be tricky to print. | ||
| It's wide, so I've had problems with PLA on a Makerbot with edges warping. | ||
| This can cause the printer to think its head is jammed. | ||
| Even if it successfully prints, warping can cause problems. | ||
| On one print, the RJ-9 holder was squished, so I had to cut down my connector to fit. | ||
|
|
||
| If printed at Shapeways or other professional shops, I would not expect such problems. | ||
|
|
||
| ### Thingiverse | ||
|
|
||
| [The 4x5 STL left/right pair](https://www.thingiverse.com/thing:2349390) from the [things/](things/) directory is in the thingiverse for public printing | ||
|

||
| ### Wiring | ||
|
|
||
| Here are materials I used for wiring. | ||
|
|
||
| * Two Arduino Pro Micros | ||
| * [Heat-set inserts](https://www.mcmaster.com/#94180a331/=16yfrx1) | ||
| * [M3 wafer-head screws, 5mm](http://www.metricscrews.us/index.php?main_page=product_info&cPath=155_185&products_id=455) | ||
| * [Copper tape](https://www.amazon.com/gp/product/B009KB86BU) | ||
| * [#32 magnet wire](https://www.amazon.com/gp/product/B00LV909HI) | ||
| * [#30 wire](https://www.amazon.com/gp/product/B00GWFECWO) | ||
| * [3-mm cast acrylic](http://www.mcmaster.com/#acrylic/=144mfom) | ||
| * [Veroboard stripboard](https://www.amazon.com/gp/product/B008CPVMMU) | ||
| * [1N4148 diodes](https://www.amazon.com/gp/product/B00LQPY0Y0) | ||
| * [Female RJ-9 connectors](https://www.amazon.com/gp/product/B01HU7BVDU/) | ||

||
| I wired one half using the traditional approach of using the legs of a diode to form the row connections. | ||
| (I'm not great at soldering, so this was challenging for me.) | ||
| For this side, I used magnet wire to wire columns. That worked okay. | ||
| The magnet wire is small enough, it wants to move around, and it's hard to tell if you have a good connection. | ||
|
|
||
|  | ||
|
|
||
| For another half, I used stripboard for the row connections. | ||
| This allowed me to presolder all of the diodes. | ||
| Then, I hot-glued this in place and finished the soldering of the other diode ends. | ||
| I like this approach quite a lot. | ||
| Connections for the diodes were much easier with one end fixed down. | ||
| On this half, I also used copper tape to connect columns. | ||
| This worked a bit better than the magnet wire for me. | ||
| For a future version, I may try just bare tinned copper wire for columns (something like #20). | ||
| With the stripboard, it's pretty easy keeping row and column connections separate. | ||
|
|
||
|  | ||
|
|
||
| Note that a telephone handset cable has leads that are reversed, so take this into account when connecting these leads to the controller. | ||
|
|
||
| The 3D printed part is the main keyboard. | ||
| You can attach a bottom plate with screws. | ||
| The case has holes for heat-set inserts designed to hold 3- to 6-mm long M3 screws. | ||
| Then, I used wafer-head screws to connect a bottom plate. | ||
| If wires aren't dangling, a bottom plate may not be needed. | ||
| You need something on the bottom to keep the keyboard from sliding around. | ||
| Without a plate, you could use a rubber pad, or you could dip the bottom of the keyboard in PlastiDip. | ||
|

| This is how the rows/columns wire to the keys and the ProMicro | ||

|
||
| NOTE: you also make sure the firmware is set up correctly (ex: change row pins with col pins) | ||

||
| ### Firmware | ||
|
|
||
| Firmware goes hand in hand with how you wire the circuit. | ||
| I adapted the QMK firmware [here](https://github.com/tshort/qmk_firmware/tree/master/keyboards/dactyl-manuform). | ||
| This allows each side to work separately or together. | ||
| This site also shows connections for the Arduino Pro Micro controllers. | ||
