By popular demand, we are pleased to present this "Do it Yourself" (DIY) guide for the Start9 Embassy personal server!

.. warning:: This DIY guide has directions for EmbassyOS version 0.2.x.  When 0.3.0 launches it will REQUIRE hardware updates, which you can find `here <https://start9.com/eos-0.3.0>`__.  Please keep in mind that version 0.3.x is not yet available for purchase or DIY!! Please stay tuned to our community channels for updates.

Motivation
==========

There are four reasons you might prefer to build your own Embassy instead of purchasing one from us.

#. You already own the necessary hardware and would like to re-purpose it.

#. You live outside the US and want to save on shipping costs.

#. You do not trust Start9's supply chain.

#. You do not want to share your shipping address.

#. You just like building things.

Building an Embassy
===================

.. Hardware: Components
.. --------------------

.. #. `Raspberry Pi 4B (8GB) <https://raspberrypi.org/products/raspberry-pi-4-model-b/?variant=raspberry-pi-4-model-b-8gb>`_
.. #. `Power supply for Raspberry Pi 4B <https://raspberrypi.org/products/type-c-power-supply/>`_ Make sure this is at minimum 15w and 3.5a.
.. #. Case for Raspberry Pi 4B (`passive cooling recommended <https://www.amazon.com/Geekworm-Raspberry-Aluminum-Passive-Heatsink/dp/B07Z6FYHCH/>`_ `*`)
.. #. A `16GB microSD card <https://amazon.com/SanDisk-Endurance-microSDXC-Adapter-Monitoring/dp/B07NY23WBG/>`_ (no need for bigger). If you have ABSOLUTELY NO data to migrate, you may choose to re-use the card already in your Embassy.
.. #. `GPIO mini speaker/buzzer <https://www.amazon.com/Corporate-Computer-Motherboard-Internal-Speaker/dp/B01527H4W2/>`_ (These often sell out, please let us know if this link needs to be refreshed)
.. #. Ethernet cable
.. #. MicroSD → USB adapter (or you may have a microSD port on your computer)
.. #. An external drive (1TB minimum, 2TB SSD recommended), or an `internal drive <https://www.amazon.com/Crucial-MX500-NAND-SATA-Internal/dp/B078211KBB>`_ with an `USB enclosure <https://www.amazon.com/gp/product/B07T9D8F6C>`_, as sold with our upgrade kits. MUST CONNECT OVER USB 3.0

.. `*` If you use a fan, **DO NOT** use the official Raspberry Pi fan, as it requires the same GPIO pins as the audio speaker. Instead, we recommend `this fan <https://www.amazon.com/Raspberry-iUniker-30x30x7mm-Brushless-RetroFlag/dp/B076H3TKBP/>`_.

.. Hardware: Assembly Instructions
.. -------------------------------

.. #. Insert mini speaker/buzzer into GPIO pins 6/8/10/12 with the word "speaker" facing out, `away from the board`.

.. #. Place the Raspberry Pi 4 board (with speaker attached), into its case.
.. #. Plug in the external drive to one of the USB 3.0 (blue) slots

.. Getting EmbassyOS: Purchasing
.. -----------------------------

.. You can purchase EmbassyOS `here <https://store.start9.com/collections/embassy/products/embassyos-software-download>`_. This is by far the easiest path to get up and running.

.. Depending on your Internet speed, the download should take between 5 and 30 minutes.

.. Getting EmbassyOS: Building from Source
.. ---------------------------------------

.. A detailed build guide will be available around the time of the v0.3.0 release (or now, if you snoop around our GitHub long enough).

.. Installing EmbassyOS
.. --------------------

.. Whether you purchase EmbassyOS from us or build it yourself, you need to flash it onto a microSD card.

.. #. Download `balenaEtcher <https://www.balena.io/etcher/>`_ onto your Mac, Windows, or Linux computer.
.. #. Insert the microSD card into your computer, either directly or using an adapter.
.. #. Open balenaEtcher.
.. #. Click `Select Image`, then find and select your copy of EmbassyOS.
.. #. Click `Select Target`, then find and select your micro SD card.
.. #. Click `Flash!` You may be asked to (1) approve the unusually large disk target or (2) enter your password. Both are normal.

.. #. Once the image is flashed and verified, you may remove the micro SD, insert it into your Embassy, and power up the device.
.. #. The Embassy is now ready for use, and you may following the normal :ref:`setup <initial-setup>` instructions. ``*``

.. ``*`` The first time you power it on, your Embassy will make more noises than future attempts, and it may take several minutes to finally complete.
