    Gather parts / notes about parts

    I bought my monitor from Amazon.  As I write this it can currently be found at this link.  If that link rots then you can search for for "Raspberry Pi Screen,NORSMIC 7 inch Monitor, IPS HD 1024×600, Responsive Capacitive Touch".  Here's a picture showing the parts that came with my monitor.  You'll be using a couple of them.

    The included Power Adapter will work but due to typical voltage drops in USB cables which will reduce the charge current, you should use a USB Micro-B adapter that puts out 5.1 or 5.25 volts at 3 A.  The official Raspberry Pi adapter works well.

    The Pi Platter can provide up to 750 mA charge current for the attached 3.7V LiPo battery.   This is a good match for a matched dual-18650 4400 mA pack.  I got mine from Adafruit.  Be sure it has the Sparkfun/Adafruit JST pinout. 

    Get the smallest HDMI to HDMI mini adapter you can find.  I had an old one that I bought when the first Pi Zero came out but it appears other models are equally as small.

    You'll also need a Raspberry Pi Zero 2 W (or Raspberry Pi Zero W) and a micro SD Card for the Raspberry Pi OS, a Pi Platter, some zip-ties and the ability to 3D print (or otherwise fashion) a simple mounting plate which is described in the next step.

    Mount Plate

    A simple mount plate is used to hold the battery pack.  It has holes spaced for the Raspberry Pi mount points on the monitor PCB, holes for the Pi Platter and zip tie cut-outs for the battery.  The design is in OpenSCAD and that file, and the generated STL are included in the "mount_plat.zip" file included in this project.

    If you don't have access to a 3D printer you can convert the design for a laser cutter or even drill a very sturdy piece of cardboard with the dimensions (mm) in the OpenSCAD source file.

    Add a set of four 0.25" M3 standoffs with nuts and zip ties for the battery.  The zip ties should be loose enough for the battery to be installed.  They can be tightened then.

    Prepare the monitor

    The monitor comes with a bunch of useful cables.  The build uses 2 of them.

    1. HDMI plug with flex cable
    2. USB Type A plug with wire harness to 4-pin connector

    The USB Type A to USB Micro-B can also be used with a power adapter to power/charge the system.

    Connect the flex and USB cables as shown below.  The flex cable has double sticky tape on one side.  I also used another piece of tape to make sure the connection was secure.

    Attach the mount plate to the Raspberry Pi standoffs on the monitor using screws supplied with the monitor.
