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

controllers

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.

Posterior Posture Videogame Controller

bathroom_scale_game_controller

Normally we see some crazy mad science projects coming from [Ben Krasnow’s] laboratory. This week [Ben] changes gears a bit and hacks his Xbox controller to interface with his bathroom scale and function as a posture controlled input device. You may want to take a moment for that to tumble around in your noggin before we trying to explain. What this means is you sit catawampus on a bathroom scale and when you lean forward your game character moves forward, lean back your character backs up and lean side to side for strafe left and right.

A modern digital bathroom scale has four pressure point transducers — one in each corner — which are read by the central controller and summed to generate the weight of the object setting on the scale. To use the scale as a controller input [Ben] removed the central scale controller and created two amplified Wheatstone bridge differential circuits, one for each diagonal axis between load cells. After adding an offset potentiometer to fix the resting point at 0.8 volts, the amplified differential voltage signals are fed directly into an Xbox controller’s thumb stick input for game control.

Additionally, to add rotation to his new game controller he hacked a an old ball type mouse and added a bit of rubber tubing that contacted and tracked the base of a  Lazy Susan platter. The scale sits on the Lazy Susan and allows for the partial rotation of your torso to controlled game rotation. However, [Ben] still needed a regular mouse interfaced with the game for full 360° rotation control.

There is more after the break, plus the build and demonstration video.

Video Game Automation Hacks

coupleofvideogamehacks

3rd party console game controllers sometimes sport a “rapid-fire” button to give gamers an unfair advantage. [Connor's] project is along the same lines, but his hack had a different goal: automate the input of GTA5 cheat codes. [Connor] admits that this is his first Arduino hack, but aside from a small hiccup, he managed to pull it off. The build connects each button on a PS3 controller via some ribbon cable to its own digital out on an Arduino Uno . After plugging in some pretty straightforward code, [Connor] can simply press one button to automate a lengthy cheat code process.

[Matt's] hack manages to save him even more user input in this second video game hack, which automates finger clicks in an Android game. [Matt] pieced together a couple of servos plugged into a PICAXE-18M2 microcontroller, which repeats one simple action in [Matt's] Sims Freeplay game: continuously “freshening” (flushing?) a toilet. To mimic the same capacitive response of two fingers, [Matt] built the two contact surfaces out of some anti-static foam, then grounded them out with a wire to the ground on the board.

Check out a gallery of [Connor's] controller and a video of [Matt's] tablet hack after the break, then check out a rapid fire controller hack that attacks an XBox360 controller.

Keyboard Spoofs 4 NES Controllers for Chiptune Goodness

NES-keyboard

This toy keyboard is being used to play music on an NES. As you probably already know, the hardware inside those original controllers was dead simple. They’re just a parallel to serial shift register that reads from all of the keys. To get this keyboard up and running [heavyw8bit] simply mounted eight chips inside the gutted toy, connecting two of them to the keyboard keys, and the rest to the array of push buttons he added to the right.

So what’s the point of using this as a quadruple game controller? Are you expecting to see what a full speed-run of Contra looks like using this as the controls? That’s not the point at all. This becomes a musician-friendly frontend for the NES synthesizer ROM called NESK-1. [heavyw8bit] wrote the game/program in order to allow you to use the original console hardware to play all of the sounds you know and love. Our favorite is the arpeggio example heard at about 2:35 into the clip after the break.

Game controller repurposed for flea market find

powerPannerControlReplacement

A jarring pan with your tripod can ruin a shot in your film, and tilting up or down usually requires some loosening and tightening kung fu to keep gravity from taking over. The “Power Panner” is a remote-controlled device that fits between the tripod and the camera, handling pans and tilts with ease. When [NeXT] found one at the Capitol Flea Market for $5, he didn’t care about the missing remote. He bought the Panner, dragged it home, and hacked together his own remote with a Sega Master Pad.

After researching similar devices online, [NeXT] had determined the original remote’s pinout: essentially a D-pad with adjustable speed control. He decided to ignore the speed pins and to instead search for a suitable replacement controller. A Sega Master Pad offered the most straightforward solution, so [NeXT] went to work separating out the wires and soldering them to a DIN connector. He couldn’t find the right plug to fit the Panner’s DIN-7 jack, so he substituted a DIN-8 with the extra pin snapped off.

Rather than use the remaining two buttons for speed control, [NeXT] chose to feed them directly into his camera to drive the focus and shutter, but the Master Pad’s wiring posed a problem: the camera would have to share the Power Panner’s ground, and the Panner plugs into the wall via a 6V adapter. Fingers crossed, he decided to push ahead and was relieved that everything worked. We suspect the shared ground won’t be a problem as long as one device uses a floating power supply, which the Panner can provide either through the proper wall wart or by using its 4 AA battery option.

If you’re in the mood for more camera hacks, check out the sound-dampening and waterproofing build from last week.
