Everything needed for the console to function is done - great!
Nibble should look like this at this point
The first thing to do next is to check everything!
Only after doing that should we go on with assembling the casings.
It would be a lot of work to disassemble the casings after we found out something doesnât work.
Thatâs why it is important to do this simple check.Â
In the box, you received three batteries. Youâll need to place these batteries inside the battery holder that youâve just soldered.
Nibble and the batteries
ï»żThe batteries are marked with two little symbols - plus (+) and minus (-), which represent the polarity of the battery. The plus (+) part has a little metal bulge at the end of it, while the minus (-) part has a little dent. This is really important since when inserting the batteries youâll have to be careful about which side goes where.
The first and the third slots in the battery holder are the same, which means that the batteries must be turned the same way when placing them inside these slots. The second (or the middle) slot, however, has the reversed polarities, which means that the batteries need to be rotated the other way round in the other two slots.
Make sure that the little switch from the second step is set to OFF before inserting the batteries!
This part is really important:Â Take a battery and place it in one of the outer two slots so that the minus (-) symbol is closer to the little spring, and the plus (+) symbol is looking away from it. When inserting it, make sure to first insert the minus (-) part so that you push the spring with the battery and then lightly insert the other part inside the holder. You need to use a little bit of strength in this process. If youâre unable to do so, ask someone older or stronger for assistance. (Itâs all about teamwork!)
ï»ż
Repeat the same process for the other outer battery slot.
Now for the middle battery slot, you have to do the same thing just the other way around. The battery needs to be reversed relative to the other two batteries. Youâre still placing the minus (-) part on the side where the spring is, and then lightly inserting the other side of the battery.
The batteries should be aligned just like in the picture.
Your batteries may not look like the ones in the photos. Make sure to follow the plus (+) and minus (-) markings for the proper insertion.  Do not do any soldering while the batteries are inside the battery holder!
Removing the protective layer from the screen
If youâre very eager to take the plastic cover off the screen, you can do so now, or you can wait until the end of the assembly. That way taking the screen cover off marks the beginning of your Nibble gaming days. (We believe that this is the right way to do so.) Â
Fuse
Before turning your Nibble on, you have to insert the fuse that will keep all of the components untouched if something goes wrong inside the circuit.Â
There are a total of three fuses and they can be replaced if needed as well.
Take one of the fuses from the package.
It doesnât matter which way you put the fuse, as long as the little black text on it is facing upwards.
Put the fuse in a little holder right next to the buzzer.Â
Remember!
Putting the fuse in its holder might be a bit tricky because you need to use a bit of force. Don't be afraid to push it inside. As long as it's facing upwards, your fuse should be fine.
Push the fuse inside
ï»żIf you can put the fuse in by using your fingers, use a toothpick or another thin object to do so.
Now that the batteries and the fuse are both properly inserted, take the console in your hands and place the switch in the ON position.Â
Turning ON
ï»żThe screen should turn on and you should see something like this!
Starting menu
ï»żIf the screen remains black, that could mean one of the two things:
-
The batteries are empty - even though we check each battery before putting it in the package, it is possible that some of the batteries are plain empty. Try to get another set of AAA (triple-A) batteries and place them in the same way as these ones.Â
-
One of the components is not properly soldered - Check for any bad solder joints, solder bridges, unsoldered pins, and residual solder somewhere on the board. ALWAYS remove the batteries and set the switch to OFF before starting the soldering process!
If youâve found a mistake in soldering, it is likely that youâve created a short circuit. In order not to fry any of the components, weâve added an additional fuse that should stop the circuit from creating any permanent damage to the components.
Replacing the fuse
ï»żAfter fixing the solder joints, itâs necessary to replace the fuse so it can provide the same short circuit protection again. Carefully remove the fuse with a toothpick or some similar tool and replace it with another one (there are a total of three fuses in the package). Â
Now, reinsert the batteries, turn the switch back to ON, and everything should work!
If the screen is showing the starting menu, that means that the soldering part is over.Â
Turn ON
ï»żYou can finally unplug the soldering iron from the power and from the device itself so that you have a completely free cable.
Leave the soldering iron to cool off completely
ï»żDo not touch the tip of the soldering iron - leave it to cool down for at least five minutes (ten would be even better).
Move it aside since you wonât need it for the rest of the assembly process.
