Battery holder cables
Let's start off the assembly by prepairing our battery holder. You'll need to remove the shrink wrap around the positive and negative connectors on the back of the battery holder.
Desolderwires from battery holder
The battery holder includes hoop connectors. We need to cut or unsolder the hoops that are attached to the wires.
Tin wires and slide switch
Next up we need to wire the slide switch to the battery holder. Prepare a slide switch by tinning two terminals. Measure two pieces of heat shrink tubing and add them to the postive red wire before soldering to the slide switch.
Slide Switch Connection
Solder the thick red wire from UBEC to the slide switch. Use hot air to shrink the tubing and secure the slide switch connections.
Solder UBEC
Solder the thicker wires from the UBEC to the positive(red) and negative(black) wires on the battery holder.
Solder the thinner from the UBEC to the postive and negative wires to the 5V and GND pins on the display backpack.
UBEC JST Connector
Remove the black connector from the UBEC (It's the one with the thin wires). You'll need to solder a short JST cable with a male connector.
Thread UBEC Wiring through back cover
Insert the JST connector from the UBEC through the hole in the center of the display cover part (displayBack.stl). Pass all the wiring through the opening.
Mount battery holder to back cover
Position and orient the battery holder over the cover so the mounting holes line up. Use four #4-40 phillips screws to secure the battery holder to the back cover.
Assembled Cover and Battery Holder
Check point. Ensure the wiring is long enough to reach the display backpack. The slide switch should be able to reach the opening in the enclosure.
Open -25mA for dimming
In this project we want the dimming feature so we need to break a trace on the display backpack to enable it.
Break the Trace
Check the back of the display backpack and look for the -25mA label. Use a filing tool or x-acto knife to remove the trace between the two pads under "Open for -25mA"
Second Slide Switch
Prepare a new slide switch to enable the dimming feature. Notice the length of the wiring is rather short, it doesn't need to reach far once inside the enclosure.
Solder dim switch
Measure two pieces of silicone wire to solder a slide switch to control the dimmer.
Mount Display Backpack to Enclosure
Position and orient the display backpack into the enclosure. Insert the display backback at an angle with the slide switch portion goin in first.
Fasten four #4-40 phillips screws to each of the tabs tosecure the display to the enclosure.
Wire JST to Display Backpack
We need to wire up a JST cable with a female connector to the display. This cable will plug into the UBEC.
Measure and cut a JST extension cable with female connector. Solder wires of the JST cable to the pads on the display backpack. Red wire to the +5V USB and black wire to GND.
Install Slide Switches into Enclosure
Use curved tweezers to insert each slide switch into the port openings near the top of the case.
Package wiring and components
Arrange the wire connections to the sides of the case, away from the pads and slide switches.
Mount back cover
Position and orient the back cover over the enclosure. Line up the mounting holes and fasten four #4-40 phillips screws to each mounting hole to secure the cover to the enclosure.
Install tripod adapter
The bottom of the enclosure features a mounting hole for a standard tripod adapter.
Place the tripod thread into the opening and install it by using a flat head screwdriver to fasten the 1/4" to 3/8" convert screw into the bottom of the case.
Test it, Display it!
Attach a charged camera battery the holder and plug in an HDMI cable. Slide the switch to power it on and connect it to your DSLR camera or other device. The second slide switch should turn on/off dimming of the screen.
