[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”
[Patrick] was looking for an easier way to control music and movies on his computer from across the room. There is a huge amount of remote control products that could be purchased to do this, but as a hacker [Patrick] wanted to make something himself. He calls his creation, “Dial” and it’s a simple but elegant solution to the problem.
Dial looks like a small cylindrical container that sits on a flat surface. It’s actually split into a top and bottom cylinder. The bottom acts as a base and stays stationary while the top acts as a dial and a push button. The case was designed in SOLIDWORKS and printed on a 3D printer.
The Dial runs on an Arduino Pro mini with a Bluetooth module. The original prototype used Bluetooth 2.0 and required a recharge after about a day. The latest version uses the Bluetooth low energy spec and can reportedly last several weeks on a single charge. Once the LiPo battery dies, it can be recharged easily once plugged into a USB port.
The mechanical component of the dial is actually an off-the-shelf rotary encoder. The encoder included a built-in push button to make things easier. The firmware is able to detect rotation in either direction, a button press, a double press, and a press-and-hold. This gives five different possible functions.
[Patrick] wrote two pieces of software to handle interaction with the Dial. The first is a C program to deal with the Bluetooth communication. The second is actually a set of Apple scripts to actually handle interaction between the Dial and the various media programs on his computer. This allows the user to more easily write their own scripts for whatever software they want. While this may have read like a product review, the Dial is actually open source!

[Dave] has some big plans to build himself a 1980’s style computer. Most of the time, large-scale projects can be made easier by breaking them down into their smaller components. [Dave] decided to start his project by designing and constructing a custom controller for his future computer. He calls it the Rabbit H1.
[Dave] was inspired by the HOTAS throttle control system, which is commonly used in aviation. The basic idea behind HOTAS is that the pilot has a bunch of controls built right into the throttle stick. This way, the pilot doesn’t ever have to remove his hand from the throttle. [Dave] took this basic concept and ran with it.
He first designed a simple controller shape in OpenSCAD and printed it out on his 3D printer. He tested it out in his hand and realized that it didn’t feel quite right. The second try was more narrow at the top, resulting in a triangular shape. [Dave] then found the most comfortable position for his fingers and marked the piece with a marker. Finally, he measured out all of the markings and transferred them into OpenSCAD to perfect his design.
[Dave] had some fun with OpenSCAD, designing various hinges and plywood inlays for all of the buttons. Lucky for [Dave], both the 3D printer software as well as the CNC router software accept STL files. This meant that he was able to design both parts together in one program and use the output for both machines.
With the physical controller out of the way, it was time to work on the electronics. [Dave] bought a couple of joysticks from Adafruit, as well as a couple of push buttons. One of the joysticks controls the mouse cursor. The other joystick controls scrolling vertically and horizontally, and includes a push button for left-click. The two buttons are used for middle and right-click. All of these inputs are read by a Teensy Arduino. The Teensy is compact and easily capable of emulating a USB mouse, which makes it perfect for this job.
[Dave] has published his designs on Thingiverse if you would like to try to build one of these yourself.
Kerbal Space Program is already a runaway indie video game hit, and if you ask some people, they’ll tell you it is the way to learn all about orbital dynamics, how spaceships actually fly, the challenges of getting to the mün. The controls in KSP are primarily keyboard and mouse, something that really breaks the immersion for a space flight simulator. We’ve seen a few before, but now custom controllers well suited for a Kerbal command pod can be made at home, with all the blinkey LEDs, gauges, and buttons you could want.
[Freshmeat] over on the KSP forums began his space adventures with a keyboard but found the fine control lacking. An old Logitech Dual Shock controller offered better control, but this gamepad doesn’t come with a throttle, and USB throttles for flight sims are expensive. He found a neat plugin for KSP made for interfacing an Arduino, and with a few modifications, turned his controller into a control panel, complete with sliders, pots, gauges, and all the other goodies a proper command pod should have.
[Freshmeat]’s work is not the only custom Kerbal controller. There’s a whole thread of them, with implementations that would look great in everything from a modern spaceplane to kerbalkind’s first steps into the milky abyss of space. There’s even one over on the Hackaday projects site, ready to fly Bill, Bob, and Jeb to the mün or a fiery explosion. Either one works.
Thanks [drago] for the tip.
