| + | Zynthian Mini kit is a cost effective approach to build zynthian with intention to give opportunity: |
| + | * to zynthian developers to get functional zynthian similar to v5 where they can do most of the testing |
| + | * to musician to get to know zynthian and learn their features before deciding to buy the professional kit |
| + | |
| + | The main features of zynthian MINI are: |
| + | |
| + | * include encoders and switches that controll zynthian software in the same way as official zynthian v5 kit using the MCP23017 i/o extender |
| + | * include MIDI IN, MIDI OUT and MIDI THRU |
| + | * include a I2S DAC for AUDIO OUT based on PMC5102 chip that is affordable to buy |
| + | * does not need any cabling inside for easy assembling |
| + | * does not need the case to test it but it include design of two type of enclosure |
| + | ** simple enclosure that only cover the top and bottom part of the device that can be also produced in the same way as PCBs |
| + | ** full enclosure that can be 3d printed |
| + | * all connectors are easy to reach (V1 does not have RPI connectors aligned to the edge of the PCB) |
| + | |
| + | To save the cost of building the Zynthian MINI, we had to sacrifice certain features that some professional musicians would need on the stage such as: |
| + | * no audio-in |
| + | * no TRS audio connectors |
| + | * not best in the class DAC for audio out |
| + | * no rigid metal case |
| + | * no zynaptik analog inputs |
| + | |
| + | Zynthian is currently at version 2. Previous version 1 was more similar to official V4 kit with only 4 buttons but it is not maintained anymore. |

| + | == Configure Zynthian MINI V2 for testing == |
| | | |
| + | Download the latest zynthian development branch from os.zynthian.org following this [https://os.zynthian.org/2024-05-04-zynthianos-bookworm-aarch64-oram-2405.zip link]. |
| + | |
| + | Flash this image to sd card with a size of at least 32GB. |
| + | |
| + | Put the SD card into raspberry Pi and connect zynthian mini to power by connecting USB-C power adapter to Raspberry Pi board. Use correct power adapter. |
| + | |
| + | Optionally you can also connect zynthian mini to network using network cable attached to Raspberry Pi. |
| + | |
| + | Wait for zynthian to start. Zynthian screen will be wrongly oriented, encoders and their push button will not work. Also none of 20 additional push buttons will work. For all this to be configured we need first to get all latest software updates that will also include required options to configure zynthian mini v2. |
| + | |
| + | === Connect to zynthian web UI to update zynthian software === |
| + | |
| + | If you have not connected zynthian to your network using network cable you will need to configure zynthian wifi first. You can do this on the screen even though screen is wrongly oriented by |
| + | * touching the top corner of the screen |
| + | * selecting admin option |
| + | * selecting wifi enable option |
| + | * selecting your network |
| + | * entering your wifi password |
| + | |
| + | You will need to find out zynthian IP address by long touching top left corner of the screen where it says "Mixer" which will open the admin page and then scroll down to Network info. Select network info where you will be able to see IP address if zynthian is properly connected to your network. |
| + | |
| + | Open browser on another computer and type zynthian IP addrese into browser's address bar. You will be prompted to login to zynthian web configuration UI. Oram default password is "opensynth". |
| + | |
| + | === Update zynthian oram software === |
| + | |
| + | After loging to zynthian web configuration UI click on "Software" from top navigation bar and click on "Update". |
| + | |
| + | [[File:Config-step-01.png|400px]] |
| + | |
| + | Wait until the software is updated. You need to make sure that it says "Update Complete" at the end of the logs. |
| + | |
| + | [[File:Config-step-02.png|400px]] |
| + | |
| + | Once you have updated the software restart the zynthian by clicking "System" option from top navigation and then selecting "Reboot". |

| + | === Configuring zynthian mini v2 as a kit === |
| + | |
| + | Once zynthian oram software is updated and zynthian restarted you can configure most of zynthian MINI hardware simple by selecting the Mini V2 Kit. To do that click on "Hardware" from top bar navigation and select Kit option. On this screen select "Mini V2" kit and Save. |
| + | |
| + | [[File:Config-step-05.png|400px]] |
| + | |
| + | Once it is saved you will need to click on restart at the bottom of the Save page. |
| + | |
| + | [[File:Config-step-06.png|400px]] |
| + | |
| + | Now all hardware is configured and should work properly. Screen orientation should be correct, proper sound card selected, all encoders and switches should work properly. What is left is just few screen UI adjustments. |
| + | |
| + | === Adjusting UI for Zynthian layout === |
| + | |
| + | Zynthian Mini V2 has all encoders on the right and therefore corresponding UI widgets need to be always on the right instead of left and right that is default configuration. Also by default cursor is visible which is not necessary when there is a touch screen. To set these two options click on "Interface" from top navigation bar and select "UI options". On this screen set the field called "Graphic layout" to "Knobs at right side (Z2, V5, MINI)" and also deselect "Enable cursor" option. |

| + | |
| + | Restart the Zynthian mini after the all configuration is done. |
| | | |
| Once everything is configured and working it is a time to put zynthian into the enclosure. | | Once everything is configured and working it is a time to put zynthian into the enclosure. |

| + | |
| + | Zynthian MINI V2 3D printable case consists of four parts: |
| + | |
| + | ;Top:This is most important part because it encloses all internal parts together. You can print just this part and have zynthian mini much more secured then just standing on stand offs. |
| + | ;Bottom:Bottom part closes the bottom of the case and comes with opening for the SD Card. |
| + | ;SD card door:This is a SD card door that is attached to bottom part for easy access to zynthian's raspberry pi SD Card. |
| + | ;Legs:These are small legs that are attached (glued) to the bottom part. They are designed to be a separate part from bottom part so that bottom part can be placed to printing bed and sliced without too much additional support. There is one stl file for one leg so you will need to print four of these. |
| + | |
| + | You can either print this case yourself if you have a printer or give these 4 files to some of your friends that have it and point them to instructions here. Also you can request somebody to print this for you on [https://www.thingiverse.com/thing:6606399 thingiverse]. |
| + | |
| + | === 3D printing instructions === |
| + | |
| + | Download all four parts from zynthian MINI V2 github repository. |
| + | * [https://github.com/zynthian/zynthian-case/tree/master/Mini_V2_3d_printable/top.stl top.stl] |
| + | * [https://github.com/zynthian/zynthian-case/tree/master/Mini_V2_3d_printable/bottom.stl bottom.stl] |

| + | * [https://github.com/zynthian/zynthian-case/tree/master/Mini_V2_3d_printable/leg.stl leg.stl] |
| + | |
| + | Print first the following parts together top, sd card door and four leg parts by: |
| + | * importing them to printer's slicing software |
| + | * make copy of leg part so taht there are four of them |
| + | * lay the top side of top.stl part onto the printer bed |
| + | * lay the top side of sd-card-door.stl part onto the printer bed |
| + | * leave legs as they are imported |
| + | * arrange all part nicely aso that they do not overlap (you can use slicers auto arange feature) |
| + | * set "zynthian mini" logo with "no support" instructions - there is not need to add support to these letters (it depend on the slicer how you do that but typically you can do this by painting them with no support indicator) |
| + | * slice it with 15% infill and with support |
| + | * do you standard preparation of you printer before prinitng (e.g. bed level, z offset etc) |
| + | * upload the print instructions from slicer and start printing |
| + | |

| + | |
| + | This will print around 3:30 hours on average commodity printers these days that can easily do 250mm/s such is Elegoo's Neptune 4 or Anycubic Kobra 2. |
| + | |
| + | [https://youtu.be/5RSKHbG7Gxg Here} is a timelapse of the print. |
| + | |
| + | Then print bottom part. Lay bottom side of bottom part onto the printer bed. Use the same settings as for previous parts. Bottom part will be printed much quicker. |
| + | |
| + | === Assembling all parts into 3D printed case === |
| + | |
| + | Here is the list of all components required to assemble zynthian mini V2 into the case: |
| + | |
| + | [[File:Case-assembly-parts.png|400px]] |
| + | |
| + | 1. Case Top part |
| + | 2. Case Bottom part |
| + | 3. Case SD Card door part |
| + | 4. Case legs parts |
| + | 5. brass heat set inserts (quantity 8) - M2.5xL4xOD3.5 - can be purchased [https://www.aliexpress.com/item/1005006071488810.html here] |
| + | 6. screws for brass heat set inserts (quanity 8) - M2.5, 6mm - can be purchased [https://www.aliexpress.com/item/4001248931159.html here] |
| + | 7. 5" DSI screen and its screws - can be purchased [https://github.com/sstojos/zynthian-mini/wiki/V2-Components-required here] |
| + | 8. zynthian MINI V2 PCB - check instructions above how to assemble it |
| + | 9. enncoder caps (quantity 4) and nuts - check PCB components required above where to buy it |
| + | 10. Neutrik 1/4 stereo connector cap - can be purchased [https://github.com/sstojos/zynthian-mini/wiki/V2-Components-requiredhere] |
| + | 11. raspberry pi 4 with heatsink |
| + | 12. raspbery pi posts and their screws |
| + | *their size depend on heatsink - the standard zynthian MINI V2 PCB build recommends two spacers connector which is 16mm long so that there is enough space for raspberry pi to cool - therefore if heatsink is 7mm then raspberry pi posts need to be 9mm (7mm+9mm=16mm) |
| + | 13. HAT posts (quantity 4) - 11mm standard. |
| + | 14. Tools required - soldering iron for inserting heat set inserts and small phillips screw driver |
| + | |
| + | === Insert 3 heat set inserts into top and 5 into bottom part === |
| + | |
| + | Heat set inserts are easily inserted using soldering iron. The first you need to put insert into the position like this: |
| + | |
| + | [[File:Assembly-1.png|400px]] |
| + | |
| + | Then put soldering iron on top of the insert and gently pushed it inside the hole so that it is fully in like this: |
| + | |
| + | [[File:Assembly-2.png|400px]] |
| + | |
| + | Here is the location of holes where heat set inserts need to be inserted for top part |
| + | |
| + | [[File:Assembly-3.png|400px]] |
| + | |
| + | Here is the location of holes where heat set inserts need to be inserted for bottom part |
| + | |
| + | [[File:Assembly-4.png|400px]] |
| + | |
| + | There are other 2 holes for heat set inserts on the other side of the bottom part. |
| + | |
| + | === Put screen inside the top part === |
| + | |
| + | First attach the cable to the screen. Then lay down the top part face down on the flat surface and put the screen through the screen opening like this: |
| + | |
| + | [[File:Assembly-5.png|400px]] |
| + | |
| + | Check that screen top is flat with top part face: |
| + | |
| + | [[File:Assembly-6.png|400px]] |
| + | |
| + | Screen opening on top part is snag enough to keep screen in place while you are moving the top part even though screen is not yet fixed to anything. Don't be confused that screen is up side down - this is intentional so that screen cable connector is close to the raspberry pi connector. |
| + | |
| + | === Screw raspberry pi posts and HAT posts to the PCB === |
| + | |
| + | Now screw raspberry pi posts and HAT posts to PCB. Here is their locations on PCB: |

| + | |
| + | Here is the location of screen screws on the PCB: |
| + | |
| + | [[File:Assembly-8.png|400px]] |
| + | |
| + | === Screw PCB to the case === |
| + | |
| + | Here is the location of PCB screws that need to be screwed into the case: |
