Chapter two - First check
Everything needed for the console to function is done - great!
Nibble should look like this at this point
Nibble and the batteries
The 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 you’ll have to be careful about which side goes where.
Make sure that the little switch from the second step is set to OFF before inserting the batteries!
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
It doesn’t matter which way you put the fuse, as long as the little black text on it is facing upwards.
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
If you can put the fuse in by using your fingers, use a toothpick or another thin object to do so.
The screen should turn on and you should see something like this!
If 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.
- 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!
Replacing the fuse
After fixing the solder joints, it’s 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).
You 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
Do not touch the tip of the soldering iron - leave it to cool down for at least five minutes (ten would be even better).
