A SEGA Dreamcast Controller With a Built-in Screen

[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”

Dial is a Simple and Effective Wireless Media Controller

[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!

The Rabbit H1 is a Stationary Mouse Replacement

rabbit h1

[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.

 

Custom Controllers For Kerbal Space Program

kerbalKerbal 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.

Robot Controller More Fun Than an Actual Wii-U

wii-u-bot-controller

Okay, that’s probably not fair since we never gave the Wii-U a try at all. But doesn’t this seem like a much better idea for controlling a robot than playing a gaming console?

The photo above is a bit deceiving because the unit actually has quite a bit of depth. Despite that, the cleanliness of the build is very impressive. [Alec Waters] started off with a backup monitor meant for automotive use (we’d estimate 7″). There’s a radio receiver, two analog joysticks where your thumbs line up when holding the controller, and an Arduino to pull it all together. If you haven’t figured it out already, this displays the wireless video from the robot he’s controlling. He’s also include an auxiliary port which lets you bypass the radio receiver and plug in a video feed directly.

Still convinced you need Nintendo’s consumer controller with a built-in screen. Yes, that can be hacked to work with all your projects. But seriously, this is way more fun.

Fubarino Contest: Custom Mech Warrior Online Controller

fubarino-contest-mech-warrior-online-controller

Twenty-two keys, a push button, three flip-switches, and a touch screen all let [Dominic] take his Mech Warrior Online game to the next level. He found that there are so many key bindings in the game it ends up being a huge pain to try to adapt his behavior to a static keyboard layout. Not only does the controller give him a specialized keypad, but he designed the touch screen interface to act as on-the-fly remapping. It even looks like something that would be mounted in a Battle Mech cockpit! What we can’t understand is why he didn’t tell us about this sexy peripheral hack much sooner?

What finally prompted him to tip us off about his project was the Fubarino Contest. Above you can see the easter egg he added to the controller. When the bottom five buttons on the touch screen are mapped to “31337” (aka “elite) the Teensy 3.0 board that drives the controller will automatically load up Hackaday in his browser.


This is an entry in the Fubarino Contest for a chance at one of the 20 Fubarino SD boards which Microchip has put up as prizes!

Using XBox One And PS4 Controllers With Everything

The controllers from the last generation of consoles served their purpose well. They were there for us when we wanted to experiment with an I2C bus, and they stood by when we wanted to build a quadcopter out of parts just lying around. A new generation of consoles is now upon us, and with them come new controllers. Controllers for which Arduino libraries haven’t been written yet. The horror.

Until those libraries are developed, there’s ChronusMAX, a USB dongle that allows you to use XBox One controllers on a PS4, PS4 controllers on the XBox, mice and keyboards on both systems, and both types of controllers on your PC.

The folks behind ChronusMAX put up a video demoing the XBox One controller working on the 360, PS3, and PC, with another video showing the same for the PS4 controller. As far as what we can see from the PC demos, everything on these controllers can be read, right down to the accelerometer data on the DualShock 4.

Although this is a commercial product, we’re surprised we haven’t seen a more open version by now. From the looks of it, it’s a very small device with two USB ports and a firmware upload utility. Microcontrollers with two native USB ports are usually encased in large packages, so there might be some very clever engineering in this device. Let us know when someone does a teardown of one of these.

Thanks [Josh] for sending this one in.
