Every kid dreams of having an arcade game at their house. When those kids grow up, they have a couple of options for getting that at-home arcade experience. They can either buy a one-game commercial game or build a multi-game MAME cabinet. Both options have the same disadvantage: they take up a bunch of space!
Arcade game-aholic, [lokesen], wanted to scratch his itch but do it with something a little less ‘big’ than a standard arcade cabinet. He came up with the only logical solution; a MAME computer stuffed inside an arcade controller.
A lot of thought went into the controller case, which is made from laser cut acrylic. It had to be large enough to allow a proper arcade-emulating spacing of the joystick and buttons as well as have room for a mini-ATX motherboard and 64gb SSD drive. The case also has provisions for a cooling fan and some exhaust vents. To finish off the case, wood grain veneer was applied to the sides.
[lokesen] chose this motherboard for a reason, it has several options of on-board video output; VGA, DVI and HDMI. Connecting this controller to any TV, monitor, or projector is a piece of cake.
The Nintendo 64 is certainly a classic video game system, with amazing titles like Mario Kart 64 and Super Smash Bros that are still being played across the world today. But, like finding new parts for a classic car, finding an original controller that doesn’t have a sad, wobbly, worn-out joystick is getting to be quite the task. A common solution to this problem is to replace the joystick with one from a Gamecube controller, but the kits to do this are about $20USD, and if that’s too expensive then [Frenetic Rapport] has instructions for doing this hack for about $2.
The first iteration of using a Gamecube stick on an N64 controller was a little haphazard. The sensitivity was off and the timing wasn’t exactly right (very important for Smash Bros.) but the first kit solved these problems. This was the $20 kit that basically had a newer PCB/microcontroller that handled the Gamecube hardware better. The improvement which drove the costs down to $2 involves modifying the original PCB directly rather than replacing it.
While this solution does decrease the cost, it sacrifices the new potentiometer and some of the easier-to-work-with jumpers, but what was also driving this project (in addition to cost) was the fact that the new PCBs were becoming harder to get. It essentially became more feasible to simply modify the existing hardware than to try to source one of the new parts.
Either way you want to go, it’s now very easy to pwn your friends in Smash with a superior controller, rather than using a borked N64 controller you’ve had for 15 years. It’s also great to see hacks like this that come together through necessity and really get into the meat of the hardware. Perhaps we’ll see this controller ported to work with other versions of Super Smash Bros, too!
Kerbal Space Program is a space simulation game. You design spacecraft for a fictional race called Kerbals, then blast those brave Kerbals into space. Sometimes they don’t make it home.
If controlling spacecraft with your WASD keys isn’t immersive enough for you, [marzubus] has created a fully featured KSP control console. It sports a joystick, multiple displays, and an array of buttons and switches for all your flight control needs. The console was built using a modular approach, so different controls can be swapped in and out as needed.
Under the hood, three Arduinos provide the interface between the game and the controls. One Arduino Mega runs HoodLoader2 to provide joystick data over HID. A second Mega uses KSPSerialIO to communicate with the game over a standard COM port interface. Finally, a Due interfaces with the displays, which provide information on the current status of your spacecraft.
All of the parts are housed in an off the shelf enclosure, which has a certain Apollo Mission Control feel to it. All [marzubus] needs now is a white vest with a Kerbal badge on it.
[Pat] was looking for a way to wirelessly control his Fire TV unit. He could have just went with one of many possible consumer products, but he decided to take it a step further. He modified a unit to fit inside of an original SNES controller. All of the buttons are functional, and the controller even features a wireless charger.
[Pat] started out with a Bluetooth video game controller marketed more playing video games on tablets. The original controller looked sort of like an XBox controller in shape. [Pat] tore this controller open and managed to stuff the guts into an original SNES controller. He didn’t even have to remove the original SNES PCB. [Pat] mentions that it was rather tedious to rewire all of the buttons from the original controller, but in the end it wasn’t too difficult. The only externally visible modification to the original controller is a small hole that was made for a power button.
In order to make this unit completely wireless, [Pat] also installed a Qi wireless charging module. Now, placing the controller on a charging pad will charge up the small LiPo battery in just about 45 minutes. This controller would be the perfect addition to a RetroPi or other similar project. If you’re not into Bluetooth, you can try using a Logitech receiver instead. Continue reading “SNES Controller Modified to be Completely Wireless”
Fighting games like Mortal Kombat provide you with a variety of different available moves. These include kicks, punches, grabs, etc. They also normally include various combination moves you can perform. These combo moves require you to press the proper buttons in the correct order and also require you to time the presses correctly. [Egzola] realized that he could just hack his controller to simulate the button presses for him. This bypasses the learning curve and allows him to perform more complicated combinations with just the press of a single button.
[Egzola] started by taking apart his Playstation 3 controller. There were two PCB’s inside connected by a ribbon cable. Luckily, each individual pad for this cable was labeled with the corresponding controller button. This made it extremely simple to hack the controller. [Egzola] soldered his own wires to each of these pads. Each wire is a different color. The wires then go to two different connectors to make them easier to hook up to a bread board.
Each wire is then broken out on the breadboard. The signal from each button is run through a 4n25 optoisolator. From there the signal makes its way back to various Arduino pins. The 4n25 chips keeps the controller circuit isolated from the Arduino’s electrical circuit. The Arduino also has two push buttons connected to it. These buttons are mounted to the PS3 controller.
Now when [Egzola] presses one of the buttons, the Arduino senses the button press and simulates pressing the various controller buttons in a pre-programmed order. The result is a devastating combination move that would normally require practice and repetition to remember. You might say that [Egzola] could have spent his time just learning the moves, but that wasn’t really the point was it? Check out the video below for a demonstration.

[Pietronet] is like many of us in that he enjoys playing some classic console video games from time to time. He usually plays them on his PC using a Wiimote as a controller. The Wiimote has most of the classic buttons in a comfortable configuration. Plus, it’s got Bluetooth built-in, which makes it easy to pair up to your PC. [Pietronet] decided to take it a step further, though. He managed to cram all of the guts from a Wiimote inside of the original NES controller for a more authentic feel.
The first step was to crack open the Wiimote and locate pads for each button. Once they were located, [Pietronet] used a Dremel to cut the board into a smaller size. He cut off part of the circuit board that contained the directional pad as well as the connector for the nunchuck. Next he had to solder very thin wires to each of the button pads he located earlier.
The original NES controller has a very limited number of buttons, and [Pietronet] wanted to modify the original controller as little as possible. Therefore, he attached a magnetic reed switch to the Wiimote’s sync button. This way if he ever needs to sync the Wiimote to a new console, he can do it by holding a magnet in the right place. This is a function that isn’t often used, so the inconvenience should be negligible.
The next step was to connect the buttons from the original NES controller up to the wires that were added to the Wiimote. [Pietronet] left the original circuit board mostly intact. He did have to cut a small chunk of it away in order to make room for two AAA batteries, but this didn’t affect the functionality of the controller.
The inside of the NES controller had to be cleaned out of various standoffs and plastic bits to make room for all of the extra components. The Wiimote has an LED to indicate that the controller is connected properly. [Pietronet] soldered a red SMD LED in its place on the end of two thin wires. This LED was then placed on the bottom left side of the directional pad. It’s visible through a translucent filter. This allows [Pietronet] to see when the NES controller is synced up properly.
The case fits back together and everything is held in place. The result is what looks and feels like a classic NES controller, only this one has Bluetooth connectivity and a vibration motor. Check out the video demonstration below to get an idea of what it looks like in use. Continue reading “Turning A Classic NES Controller Into a Bluetooth Controller”
[Fibbef] was hard at work on a project for a build-off competition when he accidentally fried the circuit board. Not one to give up easily, he opted to start a new project with only two days left in the competition. He managed to modify a SEGA Dreamcast controller to hold a color screen in that short amount of time.
The Dreamcast controller’s shape is somewhat conducive to this type of mod. It already has a small window to ensure the view of the visual memory card is not obstructed. Unfortunately [Fibbef’s] screen was a bit too large for this window. That meant he would have to expand the controller and the circuit board.
After taking the controller apart, he desoldered the memory card connectors. He then cut the circuit board cleanly in half vertically. He had to re-wire all of the traces back together by hand. It turned out initially that he had messed something up and accidentally fried the right half of the controller. To fix it, he cut a second controller in half and soldered the two boards together.
With some more horizontal space to work with on the PCB side of things, [Fibbef] now needed to expand the controller’s housing. He cut the controller into several pieces, making sure to keep the start button centered for aesthetics. He then used duct tape to hold popsicle sticks in place to make up for the missing pieces of the case. All of the sticks were then covered with a thick layer of ABS cement to make for a more rigid enclosure. All of this ended up being covered in Bondo, a common trick in video game console mods. It was then sanded smooth and painted with black primer to make for a surprisingly nice finish.
The screen itself still needed a way to get power and a video signal. [Fibbef] built an adapter box to take both of these signals and pass them to the controller via a single cable. The box as a USB-A connector for power input, and a composite connector for video. There’s also a USB-B connector for the output signals. [Fibbef] uses a standard printer USB cable to send power and video signals to the controller. The end result looks great and serves to make the Dreamcast slightly more portable. Check out the demo video below to see it in action. Continue reading “A SEGA Dreamcast Controller With a Built-in Screen”
