WIP: mkbd65 build guide v1.0 alpha

+

This is the official build guide for the mkbd65 mobile keyboard addon for modern smartphones.

+
+
+
+ +
+
+

1. Prerequisites

+
+

Before you begin, here is a list of all things you will need during the build process. There is also a list + of optional components that will make your life easier but are not absolutely neccessary.

+

What you need:

+
    +
  • + 3D printer: A 0.25mm nozzle is strongly suggested for best results
    • If you don't have a 3D printer + and also no friend with a 3D printer and there also no hackspace + nearby, you can order the prints online
    +
    • +
  • Soldering iron: Any decent iron will do
    • +
  • OpenSCAD: A powerful CAD software which will be used to create the + 3D files for the case and key mat
    • +
+

Optional requirements

+
    +
  • Reflow oven (works better then soldering by hand)
    • +
  • KiCAD: A PCB CAD software which you can use to order the PCB and + flex cable. Gerber files from GitLab should be enough for most PCB fabs.
    • +
+
+
+
+ +
+
+

2. Buy all the things

+ +
+

This section lists all things you need to buy before you can put together a mkbd65.

+ +

Main PCB

+

The main PCB is the same for all phones. The only thing that changes is the case and the flex cable that + connects the PCB to your phone. To order the PCB you can either use the Gerber files from GitLab releases or + open the project in KiCAD and upload from there.

+ +

Order with Gerber files from JLCPCB (China)

+

+
    +
  1. Download the gerber.zip file from the latest release from GitLab
    2. +
  2. Go to JLCPCB and upload the gerber.zip file
    3. +
  3. Set the PCB Thickness to 1.6mm
    4. +
  4. You can choose whatever color you like
    5. +
  5. As Surface Finish you can choose ENIG if you like, it's more expensive but easier to solder and lead free
    6. +
  6. You can use the PCB assembly service from JLCPCB if you don't want to assemble the PCB yourself
    7. +
  7. If you want to assemble the PCB yourself with a reflow oven, don't forget to buy a stencil!
    8. +
+

5 PCBs (which is the minimum order size) with HASL finish and a stencil will cost you around 15€. If you choose ENIG finish the price go be + around 30€. Assembly without compoents factored in will be around 35€.

+ +

Order from directly with KiCAD from Aisler (Europe)

+

+
    +
  1. Clone the git repo from GitLab +
  2. Open the project with KiCAD
    3. +
  3. If not already done open the Plugin and Content Manager
    4. +
  4. Install the AISLER Push for KiCad plugin from the Plugins tab and click Apply Pending Changes
    5. +
  5. Open the PCB Editor and click the Push layout to AISLER button in the top right
    6. +
  6. On the website that should open, you can go to the BOM tab and assign the components, if you want Aisler + to assemble the PCBs for you
    7. +
  7. On the checkout tab, choose "Beautiful Boards HD" if you want to assemble the boards yourself or "Amazing Assembly" if you want Aisler to do the assembly
    8. +
  8. If you want to assemble the PCB yourself with a reflow oven, don't forget to order a "Stellar Stencil"
    9. +
+

3 PCBs (which is the minimum order size) with ENIG finish and a stencil will cost you around 60€. Assembly + will cost you more then 100€, so I wouldn't recommend it. It is far too expensive. Better source the + components at Mouser or Digikey and + assemble the PCB yourself. Don't forget the stencil if you want to use a reflow oven!

+ +

Flex cable

+

Similar to the main PCB, the flex cable need to be bought at a PCB fab. The lenght of the cable depends on + the size of you phone.

+ +

Case

+

The case is 3D printed and consists of multiple parts. You can choose whatever color you like. As material + PLA is the recommended choice but others like ABS or PETG would work aswell. Feel free to experiment and share + you're results in the community chat.

+ +
+
+
+ +
+
+

3. Printing components

+

+ +

Key mat

+

The keyboard has a 3D printed layer which sits on top of the PCB. This 3D print is a bit more tricky + becasue it involves a material change. Near the stop the print will stop and you have to replace the filamaent + with a different color. This is done so the labels on the keys have a different color then the rest and are + visible. If you din't need visible labels you can skip this step and print the key mat in one go.

+ +
    +
  1. Clone the git repo with the files for the case: gitlab.com/mkbd65/cad
    2. +
  2. Design your key mat or use an existing one
    3. +
  3. slicer
    4. +
  4. print
    5. +
+
+
