Learning a new language is hard work, but they say that the best way to learn something is to teach it. [Angeliki Beyko] is learning Greek, and what better way to teach than to build a vocabulary flash-card game from Arduinos, color screens, 1602 text screens, and arcade buttons? After the break, we have a video from the creator talking about how to play, the hardware she chose, and what to expect in the next version.

Pegboard holds most of the hardware except the color screens, which are finicky when it comes to their power source. The project is like someone raided our collective junk drawers and picked out the coolest bits to make a game. Around the perimeter are over one hundred NeoPixels to display the game progress and draw people like a midway game. Once invested, you select a category on the four colored arcade buttons by looking at the adjacent LCD screens’ titles. An onboard MP3 shield reads a pseudo-random Greek word and displays it on the top-right 1602 screen in English phonetics. After that, it is multiple choice with your options displaying in full-color on four TFT monitors. A correct choice awards you a point and moves to the next word, but any excuse to mash on arcade buttons is good enough for us.

[Angeliki] does something we see more often than before, she’s covering what she learned, struggled with, would do differently, and how she wants to improve. We think this is a vital sign that the hacker community is showcasing what we already knew; hackers love to share their knowledge and improve themselves.

Typing Greek with a modern keyboard will have you reaching for an alt-code table unless you make a shortcut keyboard, and if you learn Greek, maybe you can figure out what armor they wore to battle.

As if you already weren’t agonizing over whether or not you should build your own arcade cabinet, add this one to the list of compelling reasons why you should dedicate an unreasonable amount of physical space to playing games you’ve probably already got emulated on your phone. [Rodrigo] writes in to show off his project to add some flair to the lighted buttons on his arcade controller. (Google Translate)

The wiring for this project is about as easy as you’d expect: the buttons connect to the digital inputs on the Arduino, and the LEDs on the digital outputs. When the Arduino code sees the button getting pressed, it brings the corresponding LED pin high and starts a fade out timer using the SoftPWM library by [Brett Hagman].

It’s worth noting that the actual USB interface is being done with a stand-alone controller, so the Arduino here is being used purely to drive the lighting effects. The more critical reader might argue that you could do both with a single microcontroller, but [Rodrigo] was in a classic “Use what you’ve got” situation, and already had a USB controller on hand.

Of course, fancy lit arcade buttons won’t do you much good without something to put them in. Luckily we’ve covered some fantastic looking arcade cabinets to get you inspired.

[Ryan Bates] apparently really likes building claw machines. We noticed his latest build with a new PCB, but then we scrolled down and found other incarnations of the machine going back to 2015.

The laser-cut claw is interesting looking and the brains are an Arduino. You can see the action in the video below and there are plenty of older videos on the project page.

Without the PCB, the machine was a mess of wires. With the PCB, a single ribbon cable connects the Arduino to the board, and the board has a layout of screw terminals. This results in a much cleaner layout than before.

You might think you wouldn’t see many homemade claw machines. However, that’s not true. We’ve seen plenty, some of them even using commercial claws. Naturally, some of them also connect to the Internet.

[Ryan Bates] loves arcade games, any arcade games. Which is why you can find claw machines, coin pushers, video games, and more on his website.

We’ve covered his work before with his Venduino project. We also really enjoyed his 3D printed arcade joystick based off the design of a commercial variant. His coin pushing machine could help some us finally live our dream of getting a big win out of the most insidious gambling machine at arcades meant for children.

Speaking of frustrating gambling machines for children, he also built his own claw machine. Nothing like enabling test mode and winning a fluffy teddy bear or an Arduino!

It’s quite a large site and there’s good content hidden in nooks and crannys, so explore. He also sells kits, but it’s well balanced against a lot of open source files if you’d like to do it yourself. If you’re wondering how he gets it all done, his energy drink review might provide a clue.

Over at [Truthlabs], a 30 year old pinball machine was diagnosed with a major flaw in its game design: It could only entertain one person at a time. [Dan] and his colleagues set out to change this, transforming the ol’ pinball legend “Firepower” into a spectacular, immersive gaming experience worthy of the 21st century.

A major limitation they wanted to overcome was screen size. A projector mounted to the ceiling should turn the entire wall behind the machine into a massive 15-foot playfield for anyone in the room to enjoy.

With so much space to fill, the team assembled a visual concept tailored to blend seamlessly with the original storyline of the arcade classic, studying the machine’s artwork and digging deep into the sci-fi archives. They then translated their ideas into 3D graphics utilizing Cinema4D and WebGL along with the usual designer’s toolbox. Lasers and explosions were added, ready to be triggered by game interactions on the machine.

To hook the augmentation into the pinball machine’s own game progress, they elaborated an elegant solution, incorporating OpenCV and OCR, to read all five of the machine’s 7 segment displays from a single webcam. An Arduino inside the machine taps into the numerous mechanical switches and indicator lamps, keeping a Node.js server updated about pressed buttons, hits, the “Lange Change” and plunged balls.

The result is the impressive demonstration of both passion and skill you can see in the video below. We really like the custom shader effects. How could we ever play pinball without them?

Ok this is not a project 100% core Arduino, because it uses custom hardware and only the bootloader of Arduino. But Arduino follows the Open-Hardware philosophy, so we are honoured to share this project that use a bit of Arduino. [chris] , from silverball software, sent us his way to build a game controller , programmed with Arduino software.

Well after a few months of tinkering and several designs I finally have one.
The design is based around the Atmega 328 running the Arduino bootloader. There is a RN42-HID bluetooth module that allows serial communication between it and the microprocessor.

I wanted the device to be fully hackable so I designed it with headers for both the bluetooth module and the Atmega 328 chip. I can reprogram the bluetooth module to run HID keyboard or mouse (or combined), it can iterate as a gamepad, or it can reconfigured to run serial protocol and iterate as a virtual com port.

On the [website] there is full description with lots of pictures, have a look.

Head to head video game action can’t even compare to this use of a coin-op Sega Rally game to race actual RC vehicles. Take a close look at those screens and you’ll see there are no computer graphics, just a feed for a camera on each of the toy cars.

The project was conceived for the Sapo Codebits VI conference in Portugal. The arcade cabinets had their controls connected to an Arduino, but getting video up and running wasn’t nearly as easy. After fruitless attempts to get the original CRTs to work the team ended up replacing them with functioning CRT units of the same size. The cars themselves have two camera, one on top of the vehicle’s cab and one mounted on a boom for a perspective that was above and behind the vehicle. The drivers can switch between either view. The cars were set loose in the room serving as the event’s retro gaming area and players were free to race each other wherever they pleased. Don’t miss the video clip after the break which shows off all of the fun.

[Timothy], a 15 years old Arduino enthusiast has sent us his first Arduino Project, an arcade interface based on Arduino Leonardo.

The cabinet is made of 4mm HDF and were laser cut at “Fabriken” in Malmö. The red arcade sign in the top is produced in 5mm translucent acrylic. All design and construction drawings were made in Illustrator. I used an Arduino Leonardo to connect the joystick, buttons and the LED light.  The game installed, Superstar Chefs, is an old game developed by my dad’s cousins. My prototype board was made with Fritzing.

It includes:

- 6 green 3mm LED’s,

- 11 resistors (6 330 ohm, 4 10K ohm and one 100 ohm),

-1 dip8 socket with an ATtiny45,

- 1 potentiometer,

- 4 pushbutton and header sockets.

I created this prototype board to easily get started with Arduino.

Timonthy, welcome on board!

We've seen attempts at recreating video game racing in real life. For Artica and The Arcade Man, there's no desire to preserve the illusion -- they've jury-rigged two Sega Rally cabinets to control the strictly real-world racing experiences of RC cars. Their two-machine setup from the recent Codebits VI event in Portugal yanks the original arcade computing power in favor of an Arduino-powered system that maps the steering wheel and pedals to the tiny vehicles through a wireless Xbee link. The setup does make a nod to traditional video games through the cameras, however: drivers can pick either an arcade-style overhead camera or jump to a cabin-level view. The only true challenge during the build process was to find viable displays for the rigs, as the original CRTs proved too problematic for the retrofit. Some might consider it sacrilege to gut a classic cabinet for the sake of some RC action, but the end result is a racing experience that's at once very familiar and yet surprisingly fresh. Spectators had better watch their feet, though -- the competition might get fierce out there.
