Chapter four - Casing up
All six of the transparent protective Nibble casings in one place (with the protective layer on)
Removing protective layers
Peeling off the edge of the layer is the easiest way to go
In order to peel them off, take a toothpick, or your nail, (but not any metal or other sharp objects) and carefully scratch off a bit of the cover from one of the corners of the casing. Once that is done, take the plastic with your fingers and slowly peel it off the casing. Satisfying? Oh yeah!
Slowly take off the protective layer so it doesn't break midway
You’ll notice that the casing is still not completely clean. There is also a layer of this plastic on the other side. Each casing has two of these protective films, one on each side. That means that you have to take off a total of twelve plastic covers before continuing.
Make sure to remove the layer from both sides of the casing
Casings after the protective layers have been removed
When all of the casings are nice and clear, continue to the next step.
Placing the casings
Everything needed for these next few steps
Firstly it’s important to separate the back casings from the front ones. You’ll notice that the back casings have a much bigger middle cut out and that the two sides of plastic are only connected on the bottom. On the contrary, the front casings have rectangular holes in the middle of the casings and the sides are connected both on the top and the bottom.
The first layer of the front casing
While you're holding the back layers of the casing and the one layer at the front, take the 4mm golden spacer (the smaller one) and it through one of the holes on the upper side of the board, close to the side edge.
Now it’s time to take one of the bolts. For this one, take the 8mm metal bolt, the one that is not the shortest, but also not the longest.
The 8mm metal bolt
Place the bolt through the hole on the back side of the board where you just placed the golden spacer.
Placing the bolt into the hole
Repeat the same process on the other side of the board, with the same sized bolt and spacer.
Both bolts and spacers placed and tightened from the back
Both bolts and spacers placed and tightened from the front
You're doing great! Half of the job is done!
Placing the middle layer
Placing the top layer - the final layer of the "sandwich"
These casings are probably going to fall off pretty easily now. That’s why we need to make them stick. Take two of the smallest 6mm bolts and place them inside two golden spacers that you’ve already put in place in the previous step.
Tighten them using the screwdriver.
The 6mm bolt
Making sure everything stays in place while placing the rest of the bolts and spacers
Now both casings are in place and won’t go anywhere.
The 16mm bolt
Put the bolt in one of the holes in the casing from the front side (the side where you can see the screen).
Take the spacer and place it on top of the bolt from the back (mostly white side of the board). Tighten the bolt and the spacer using the screwdriver. Repeat the same process for the other hole.
Tighten them with a screwdriver
If the batteries are already inside the battery holder (which they should be from the chapter - first check) then you just have one final step left!
Putting the plastic cover on top of the batteries
Take another two smallest 6mm bolts and screw them into the spacers, so that the battery plastic cover gets nicely tightened up.
Tightening the bolts on the battery cover
Use the screwdriver to tighten all of the bolts if necessary additionally.
Only one more final step to do before turning it on. You can now finally take off the plastic peeling from the screen (if you haven't already). Just grab the little green part and peel it off.
You should be proud of yourself - it's game time!
Make sure you turned off your soldering iron! Unplug it from the power source, place it on the soldering iron stand and let it cool off for at least 5 minutes before you put it away in your tools box.
