Making my retro Arcade Cabinet last summer was one of my all time favorite projects. It been one of my most popular videos ever, and many of you have sent me awesome pictures cabinets you built that were based on my arcade cabinet plans. One piece of feedback that I have gotten over and over is that this cabinet is too large and too complex for many of you. Some of you wanted me to cover the electronics in the plans (rather than just the woodworking portion). Well I am happy today to bring you the RetroPie Bartop Arcade Cabinet! This cabinet, as the name implies, is much smaller and can sit on top of a desk, table, or bar. The monitor is 24 inch, instead of 27 inch, reducing the width of the cabinet by a full 4 inches. The computer is a Raspberry Pi running a RetroPie which makes installing and setting up the game system incredibly simple.
Some of you will undoubtedly ask why I would use a Raspberry Pi instead of a full PC, like in my original full-size arcade build. There’s a bunch of reasons!
The Raspberry Pi is only $35. Literally anyone can afford to buy a Raspberry Pi!
The emulation software is pre-built and pre-configured. All you have to do is download it and place it on an SD card. It honestly couldn’t be any simpler.
Many other games like Quake, Doom, Duke Nukem 3D and others have free ports to the Raspberry Pi which usually come included in your download of RetroPie. This means with literally no additional work, you can be playing all kinds of old PC games too.
There are emulators for the Commodore 64, Amiga, Nintendo, Atari, etc all included.
The RetroPie interface is clean and super easy to use.
The Raspberry Pi has a general purpose Input/Output (GPIO) that can be used to control all sorts of things, such as flashing lights, sounds, or even flash your lighted marquee. Imagine if you get shot in Quake and the marquee flashes or the cabinet vibrates. All of that is possible with the GPIO pins of the Pi.
All of that being said, most certainly all of this can be accomplished with a PC. It will just cost more and take a little longer and in some cases require a few extra add-on components.
The Controllers and Buttons for the Bartop Arcade
On this build I decided to switch from the X-Arcade joystick and controller over to the Sanwa Arcade Joystick & Buttons and Easyget LED Arcade Controller. I did this because I wanted to add some color to the cabinet and I also wanted the buttons to have LED lights in them, so that I could put transparent labels under the buttons. I felt like this would make a really cool effect. I bought one red joystick, ten red LED lit buttons, one blue joystick, and ten blue LED lit buttons.
The only real downside to the Sanwa solution over X-Arcade is that each set of joystick and buttons requires a separate EasyGet controller. If USB ports are at premium in your arcade you’ll need a USB hub to use them. In addition, you’ll have to find additional space to mount each controller board on the inside of the control panel.
Finally, I do really love the ball top joystick as compared to the teardrop provided by X-Arcade. It just feels very retro and has that old-school arcade look!
Constructing the RetroPie Bartop Arcade Cabinet
Step 1: Layout the Side Panels
The first step is to layout the side panels on a sheet of MDF. You only need to draw out one panel, because we will cut both panels at the same time.
Step 2: Draw in the Curves
You’ll need a compass to make the curves. Unfortunately the little store bought ones won’t work. I made one out of nothing but a 14 inch piece of scrap wood and a bolt. The easiest solution would be to use a 14 inch string, with your pencil tied to one end and a nail tied to the other.
Step 3: Cut Out the Side Panels
Cut the MDF panel in half and sandwich the left and right panels together. Clamp them to a table, and then use your jigsaw to cut them out. Once your finished with the cut, unclamp the sides and fold them open. This will reveal two exact copies a mirror of each other.
Step 4: Install the Connectors
To connect the side panels the center panels you could just glue and brad nail them directly together (or use screws or nails). However, that would be incredible hard to hold in place during assembly and it would also be difficult to make sure both sides were perfectly aligned and square. To make it easier, first we lay out 3/4 x 3/4 inch connectors on the panels. We can take our time and measure everything out, and then glue and brad nail those to the panels. But! This also has another great benefit: No visible nails or screws on the outside of the cabinet that will need filling later!
In my case I am using 3/4 inch MDF to build my cabinet, so these connectors are inset exactly 3/4 inch. You’ll need to adjust your spacing if you go with a thicker or thinner material.
Step 5: Assemble the base Arcade Cabinet
With step 4 done, assembling the arcade cabinet is almost as easy as legos.
Step 6: Route the T-Mold Slot
This is a completely optional step depending on how you want your finished arcade to look. I personally love the retro look with T-Molding. T-Mold requires a slot in the MDF. You have to route all of the components before final assembly, otherwise your router won’t reach the internals. If you’re not going to add T-Mold, you can skip this step.
Step 7: Install the Front and Back Panels
Now that we’ve routed all of the T-Mold slots we can finish install the panels. On the backside we’re leaving a large 14 inch hole. We’ll make a door to cover this in a later step.
Step 8: Drill the Control Panel
The control panel can be a real pain to drill out accurately. That’s why the plans include a glue on drilling template. Just glue this drilling guide to your control panel and with spray adhesive, drill the holes and then remove it by peeling it off. I recommend Super 77.
Step 9: Install the Back Door
The back door of the cabinet will be used for maintenance purposes.
Step 10: Drill for the Speakers
Another really hard thing to get aligned is the speaker holes. They consist of 60 holes on each side of the cabinet. I’ve included a left template and a right template with the plans. Hitting the holes with a sanding sponge will make them look like they were made at a factory.
Step 11: Prime the Bartop Arcade Cabinet
It is critically important to prime MDF. MDF by its nature will soak up paint. Ultimately MDF is nothing but glued together sawdust. I really like to use Rust-Oleum’s Filler Primer with MDF. It will fill any tiny cracks and imperfections. The only downside is that you absolutely must hit it with sandpaper between primer coats and before painting. It is worth it though because this will leave you with an incredibly smooth base to lay your paint on top of. It changes everything when painting MDF.
Step 12: Paint the RetroPie Cabinet
In my full-size arcade cabinet build I got a lot of comments like “Yeah, anyone with an HVLP sprayer can paint like this.” So with this build I decided to do everything with rattle cans. I can assure you the paint came out just as good.
Step 13: Install the Electrical
I installed a quad outlet plug inside the arcade cabinet. This provides the exact number of outlets needed to run the RetroPie Arcade since most everything else is USB powered.
Step 14: Install the T-Molding
The T-Molding pops in the to T-Slots we routed earlier. I find the best way to install it is with a small rubber mallet. At the 90 degree turns you’ll need to notch the ribbed track to allow it to curve around the corners. It makes for a very clean look.
Step 15: Install the Marquee Light
I like to line the inside of the marquee’s slot with reflective tape. This makes for a cleaner look once it is lit. The LED light is simply a cheap $20 light from the local big box store.
Step 16: Assemble the RetroPie Arcade Control Panel
Install the joysticks into the arcade with four screws. Install all of the buttons and screw the large plastic ring nut to the back. Then plug all of the controls into the controller boards.
Step 17: Assemble the Major Components
Install the control panel board and install the monitor. The monitor just slides ins place and is held by friction.
Step 18: Install the Raspberry Pi
Install the Raspberry Pi. I used an industrial adhesive backed velcro to hold all of the components in the back of the cabinet.
Step 19: Install the Lighted Marquee
The Marquee banner is just a poster I had printed at a local office supply store for $5. It is sandwiched between two pieces of plexiglass that I cut out on the tables saw.
The Completed RetroPie Bartop Arcade Cabinet
The completed cabinet turned out awesome! I am super excited with this one! Stay tuned for future projects and we’ll break down some of this build into more detail, including the specifics of loading the Raspberry Pi!
Check out some of these truly amazing looking builds from our customers, based on this set of bartop arcade plans.
Hey guys! It’s Mike, from The Geek Pub! And on this episode we’re going to make this awesome BarTop Arcade cabinet using a Raspberry Pi!
The first thing we want to do is layout the side panels of the RetroPie Arcade Cabinet onto a section of medium density fiberboard. As alway, you can get all of the dimensions in the plans at TheGeekPub.com.
After drawing a rectangle the size of the arcade cabinet, I used my angle finder and a straight edge to transfer the angles.
I couldn’t find my square, so I just used piece of known square plywood to make a 90 degree line for the front of the marquee.
You’ll need a compass to draw the large curved section of the side panels. Rather than buy one, I just used a scrap piece of oak, a pencil, and bolt with a pointed end to make my own. You’ll need to make two tick marks from each end. Wherever they meet is the where you’ll place the center of the compass to connect the top and bottom.
I used my table saw to cut out the rectangle, and then made a second rectangle. The second one will be clamped under the first one. This will allow us to cut out both side panels in one go.
I used my air compressor to keep the sawdust out of my way. This keeps the line highly visible while I cut out the side panels of the arcade cabinet. The best rule of thumb I can give you when using a jigsaw is: Go slow! Take your time. It makes a big difference in the finished product.
Once the panels are cut, open them up on the workbench like a book! You’ll have two identical side panels for your arcade!
I cut out a bunch of sections of 3/4 X 3/4 inch MDF to use as connection points inside the bartop arcade cabinet. These are inset exactly 3/4 inches. This not only makes the assembly of the arcade cabinet easier, but has the benefit of leaving no exposed nail heads or screws on the outside of the arcade cabinet.
Where appropriate, rather than measuring I simply used spacer of the right size. This ensures my spacing will be dead on accurate. You can cut these spacers from scraps. Simply pull them out and discard them afterwards.
You can use also reuse the spacers as angle finders and place holders when gluing and nailing in your connectors.
The next step is to glue and brad nail the side panels to the top and bottom panels. Be sure to make sure everything is square. If you don’t have a brad nailer you can use screws or just use clamps and wait for the glue to dry.
The 3/4 inch connector pieces we put in earlier make assembly super simple. All you have to do is add glue and line everything up. Again, I am using brad nails to speed up the process. The brad nails are simple there to hold everything together long enough for the glue to dry.
I love the retro look of T-Molding on arcade cabinets. In order to install T-Molding, we need to cut a T-slot in the side panels and all of the components. You have to do this before final assembly as the router will not reach everything after assembly.
Now that we’re done with the routing, we can simply install the remaining panels. We’ll start with the bottom panel of the marquee.
This board will be the bottom frame of the LED monitor.
Then we will install the front of the control panel. This board is slightly inset for a 3D appearance.
On the backside we just need to frame in where the access door will go.
I created this awesome drilling template that you can get on TheGeekPub.com. Just lightly coat the back of it with spray adhesive and press it to the control panel. Using the template makes it super simple to drill out all of the holes for the joystick and the buttons. It’s also a fantastic reference sheet for install the buttons later.
I used my drill press and Forstner bit to drill out the holes, but you can use a handheld drill and a paddle bit in a pinch.
Once you’re finished, just peel the template off and discard it.
I cut a section of MDF the exact size of the access panel in the back of the arcade and installed it using a piano hinge and a small latch. This will allow future access to inside of the cabinet for maintenance reasons. I used a couple of paper spacers to center it and my square to make sure everything would open and close easily.
The arcade cabinet has two speakers, one on each side of the cabinet. Provided in the plans is a drilling template for each side to make drilling the 120 holes much simpler. Just attach them with spray adhesive. And then get ready to drill and drill and drill and drill.
When your finished drilling, just remove the template and use a sanding block to remove any burs, it will look like it was made in a factory.
The next step is to prime the MDF. Primer is critical if you want an awesome finish. When I prime MDF, I like to use filler primer as it fills in all the little imperfections. You’ll need to sand it with 220 grit sandpaper before you paint it though.
In my full-size arcade cabinet everyone told me that it was easier because I had an HVLP sprayer, so for this cabinet I am using rattle cans from my local home improvement center. I decided to go with flat black.
With the cabinet laying on its backside, I installed some polyurethane feet to keep the cabinet from sliding around not he table.
I installed an electrical box in the back of the cabinet and then drilled a hole to accept the power cord. This will be the electrical system for the entire cabinet.
In the electrical box I installed quad outlets, exactly the number of plugs necessary to power the RetroPie Arcade!
The next step is to install the T-Molding. I find the best way to get a smooth finish is to use s small rubber mallet. Take your time and go slow and the results will be fantastic.
When you get to one of the 90 degree cuts you’ll need to cut the track section of the T-Molding to allow it to bend around it. This really makes for a nice seamless look.
In order to make the lighted marquee more uniform in appearance, I like to line the inside of the marquee with reflective tape. Once that’s done I install an 18 inch LED light from the local big box store.
Installing the controls is very simple. Each joystick requires four screws, i recommend pre-drilling these to make sure they sit flush.
The tops of the joystick have a black washer to cover the hole and then you just screw on the balls.
Then its just a matter of inserting all of the button into their respective holes.
On the back of the board you just install a large plastic nut on the back of each button.
Now it is just a matter of plugging every button into the correct socket on the controller board.
I love these USB powered speakers because they fit perfect in arcade cabinets and don’t take up much room. I just use hot glue to hold them in place, and they be easily removed with a heat gun.
This is where the really fun part begins. Final assembly! Start by popping the controller board in place and and installing the monitor.
I like to use this industrial adhesive velcro to hold the components in place. It allows you to easily remove them later for maintenance but will last forever.
For cable management I use this two sided velcro stripping to roll up the wires.
You can get your marquee printed at any office supply store’s copy center for about $5. Then you just need to cut it to fit the size of your marquee. You’ll sandwich it between two pieces of clear plexiglass. Don’t forget to peel off the clear plastic protector it comes with.
The marquee banner just drops into place.
To keep it from coming out I just glued in two small 1/4 inch pieces of MDF that I pre-painted black.
The last step is to plug in the LED light!
OK! Well I think this cabinet might have been more fun than my full-size arcade cabinet and the reason why I think is because I used a Raspberry Pi. Now a lot of you are probably asking “Why did I use a Raspberry Pi?” Well the first reason is very simple. It costs $35 dollars. Literally anyone can afford to buy a Raspberry Pi! The second reason is RetroPie. So RetroPie is preconfigured. You just download it from their website. There’s no configuration trying to figure out how to get some front-end to work or some game to work. You just download the entire RetroPie image and load it on your Raspberry Pi and you’re done. You’re ready to go. All you have to do then is drop your game ROMs on. The third reason is that the Raspberry Pi has GPIO. Now I did not use any of the GPIO features on this cabinet. But if you wanted to have a game say where if you crashed, the cabinet would shake. Using the GPIO off the Raspberry Pi would make that incredibly simple. And then finally the fourth reason is no cooling. So the Raspberry Pi puts off almost no heat. So you can put the Raspberry Pi in here with no fan and you are ready to go. If you wanted to use a PC in this cabinet instead of a Raspberry Pi I would probably just add a fan to the back door and plug it into one of the USB ports.
Well guys, stay tuned for some future videos, because we’re going to break this down a little but farther. We’re going to talk about the Raspberry Pi and how to load RetroPie and some of those other things as well as how to connect the control boards in a lot more detail. So look for those coming up.
