Chapter One - Soldering the components
Part One - The buttons
Here you will need the main board and all the buttons
The main part of the console, besides the screen, are the buttons. In order to move, shoot, dodge, jump, and pause in games, you need to have some kind of input.
The button pins need to go through all the way
The buttons should go through the holes all the way and make a little click when it falls in place. Got it? Awesome, now let’s solder!
In case you have a soldering iron with a touch sensor, don't remove your finger from the sensor as long as you are soldering since removing the finger from the sensor will turn the iron off!
The solder is needed in order to make an electric connection
Firstly, carefully place the soldering iron on one of the pins, so that it’s touching both the pin and the little plated area around the hole that the pin is going through.
Bring everything together and watch it melt
Make sure to create a volcano-like shape so that the base of the joint is filled with solder but the top is getting thinner and thinner.
Only when all four pins are soldered the button will work properly
Congratulations! One down, many more to go.
Cleaning the tip of the soldering iron
The same process must be applied to all of the buttons. Take your time, be patient, and remember - always double-check your solder joints!
Soldering the rest of the buttons
After all seven buttons are soldered, a total of 28 connections must’ve been made. Check if all of the buttons can be clicked.
Clean the soldering iron using the sponge and place it on the metal holder.
Part two - the switch
Unfortunately, the console cannot stay powered on all the time, and sometimes you have to switch it off. This is where the switch comes in. You can easily switch the console on and off with one simple push.
Starting the soldering process
Soldering these pins requires a little bit more precision since they are close together so it’s a lot easier to bridge them accidentally - like this!
Example of a solder bridge
Pins should look like this after the bridge has been removed (or if the bridge was never there)
After soldering all of the five pins, try the switch a few times. It should click when switched on/off. If everything seems alright, continue with the build.
Part three - The screen
The screen goes into the middle pins on the console
Since this is pretty much the most important part of the console, together with the processor, you should treat it with care.
Put all of the pins through the holes
Even though the screen has its protector, try to touch the black part as little as possible, so that it doesn’t get damaged. Especially avoid touching any part of the screen with the soldering iron, hot or cold (except the pins, duh!).
- Solder the first pin in the row.
- Check if the screen sits flat on the board and is vertically soldered to the board.
- If needed, resolder the first pin in the row to make the screen more vertical or closer to the board.
- Resume with soldering the rest of the pins.
After you finish soldering, check all the joints and make sure the screen is sitting flat and firm on the mainboard. Any sideways movement is not good and should be checked and fixed.
Make sure your soldering joints are as clean as possible
Part four - The battery holder
Put the battery holder all the way through
Again, pick up the soldering iron and solder the two pins. As easy as it gets!
Clean the soldering iron and put it on the metal stand away from the console.
