Now in the world of retro gaming, people aren’t happy with a circuit board sitting naked on their TV stand / computer desk with bundles of wires and cables poking out. They want to replicate the feeling of playing on their old favorite console, but with the added twist of seeing the surprised looks on their friends’ faces when they startup a custom system running lots of different console emulators. So here is an awesome Step-by-step guide on how to build your own Raspberry PiStation I found over at Pi-supply.com
Thankfully, taking apart the PlayStation case is pretty straight forward and can be done using a Philips head screw driver! If you flip the console over, you will find 6 screws underneath. Take these out and then flip back right-way around and you should be able to lift the top off the console. Remove everything with the exception of the power supply (PSU) located on the left-hand side of the console and separated by a plastic divider. Dis-assembly is pretty straight forward, simply removing a few screws and gently removing any connected cables.
You can use the existing power and reset switches instead of messing around with shutdown and reboot commands. You can also use the Mausberry Circuit for this because they had an option to solder your own switch to their circuit board, and rather than add your own switches simply use the existing ones.
If you wanted to make a subtle change to the PiStation visually, then changing the LED from the original green one is a simple yet effective option. The LED is soldered in and then protected by a plastic surround, which is easily removed by gently pressing the black plastic points on the underside of the PCB and gently pulling from the top until it comes off. You will then see the LED legs and you can then remove by using the soldering iron on the underside and gently pulling until it comes out. When you remove the LED, you should see a marking on the PCB indicating which hole is the anode (positive) and which is the cathode (negative) which looks similar to this:
On my PCB, the anode was the hole nearest to the edge of the PCB, but double check as yours may be different! You need to know this so you put the LED in the right way. For reference, the longer leg on the LED is the anode (positive) and the shorter leg the cathode (negative – if you are interested you can read more on LED and Diode polarity here). Once identified, pop the LED into the PCB and then solder in place and replace the black plastic protector.
The switches are a little trickier as there are 4 points instead of 2 to look out for (although only two are used). After much trial and error, I managed to figure out which points were needed, so they are as follows:
Once identified, Solder the wires to and from the Mausberry Circuits board (take a look at their website here for detailed instructions on getting this up and running) and as a result my customised PCB looked like this:
You may have noticed that I have soldered my wires to a point on the right-hand side of the board – this is a breakout point like the GPIO’s on the Raspberry Pi and makes connecting to the Pi itself a bit more accessible. You can connect your wires directly to the GPIO’s on your Raspberry Pi, but I wanted to utilise the additional connector as it was easier once reassembled.
The black (negative) wire also has a 330 Ohm resistor inline. I have insulated this with some electrical tape…some people have since told me this is not necessary but I preferred to be safe rather than sorry!
The red (positive) point is connected to the LED point on the Mausberry Circuit and the black (negative) point is connected to any ground pin on the Raspberry Pi. It is a simple circuit that turns on when there is power to the Pi and off when there isn’t. There are also two additional pins connected to the Mausberry Circuit which is explained on their setup page.
Now that the LED and switch has been integrated into our circuit, you should now have the Mausberry Circuit connected to the switch and your Pi. This is a close-up of the completed Mausberry Circuit (quick note – I couldn’t figure out how to get the reset switch working but I left wires soldered to the switch just in case I did in the future):
Rather than run wires in places that may get pinched when the case is put back together, I cut a small hole in the dividing plastic wall using a drill and a small file to run my wires through. It might look a little messy, but once the console has been reassembled, nobody will notice:
I also drilled a hole in the original power point on so that I could run my micro-USB power supply into the console. This is just a bit of trial and error using a drill and a small file until the hole is big enough to allow the cable to pass through:
The complicated stuff is now out of the way and the rest is simply putting everything together. If you have bought a Wifi USB dongle, pop that in your Pi along with the Bluetooth USB dongle. Don’t forget to put your RetroPie loaded SD card into your Pi too! Cable management is a little tricky and the shorter the cables used, the better, otherwise you’ll end up with lots and lots of cable that needs dealing with! This is how mine looked once everything was put inside:
The last part is to reassemble the case and pop the lid back on. Pop the 6 screws back in and then you should have a complete Raspberry PiStation! The next challenge is to configure all your emulators, controllers and so on but we can look at that another time! Here are some more pictures to show the completed PiStation:
