Planet Arduino

Small in size, low-resolution, blocky segments, and a limited color palette — all characteristics of the typical vacuum fluorescent display, any of which would seem to disqualify them as the display of choice for a lot of applications. But this is Hackaday, and we don’t really pay much attention to what we’re supposed to do, but rather to what’s fun and cool to do. So when we see something like a VFD game console, we just have to sit up and take notice.

In a lot of ways, the design of [Simon Boak]’s Arduino-based VFD console is driven by his choice of display. The Noritake Itron GU20X8-301 VFD is a “tricolor” display with eight rows of 20 rectangular pixels. Each pixel is composed of six short linear segments, with alternating red and blue colors. Turning on either set of segments yields one of the two base colors, while turning on both yields a sorta-kinda whitish color, if you squint a bit.

[Simon] chose a two-piece design for his console, with a separate controller and display. The controller holds the Arduino Nano and all the controls, plus a piezo buzzer for fun. The display case connects to the controller with a ribbon cable and holds the VFD power supply and driver. To celebrate the retro look of the VFD, both cases are decked out with woodgrain side panels. [Simon] chose appropriately blocky games for the console, like Snake, Conway’s Game of Life, and the venerable snow demo. We’d imagine Pong would be a good choice too, as well as perhaps Tetris if the display were flipped on its side.

We really like the look of this console, and we appreciate putting an otherwise obsolete display to use in a creative way. If you want to learn a little more about these displays, check out this love letter to the VFD.

VFDs (vacuum fluorescent displays) were common a few decades ago and have a nice, distinct glow that many find appealing. But like Nixie tubes and CRTs, VFDs have are outdated and almost obsolete at this point. They can’t come close to matching the price or functionality of modern LCD and OLED screens, but they still have a lot of charm. Simon Boak harnessed that charm when he built this custom video game console that features a VFD.

This console is 100% custom and looks fantastic. It has two parts: the display and the controller. Both have enclosures made of formed sheet metal and wooden side panels, which enhance the retro aesthetic. Users can run Conway’s Game of Life, play a snake game, watch a snow animation, or draw within a painting program. If the user wants to keep their art, they can save it to EEPROM for later viewing.

Boak originally planned to build this as a custom 6502 machine and program everything in Assembly, but realized that that plan was a bit too ambitious. Instead, he built this console around an Arduino Nano board. The screen is a Noritake Itron Gu20x8, which can display three different colors across the 20×8 grid of pixels. The controller uses an array of push buttons and there is a piezo buzzer for sound effects.

While the current game/program selection is limited, Boak now has a console for which he can develop as many games as he likes.

Numbers are wonderful things when applied to technical specifications. Take [Bobricius]’ handheld Arduino-based game console. With an 8×8 LED matrix for a display it’s not going to win any prizes, but while he’s pushing the boundaries of dubious specification claims he’s not strictly telling any lies with his tongue-in-cheek statement that the graphics are 64-bit.

Jokes aside, it’s a neatly done build using a DIP version of the Arduino MCU and all through-hole components on a custom PCB. Power comes from a CR2032 cell, and it includes three buttons and a small piezoelectric speaker. He’s implemented a whole slew of games, including clones of Pong, Breakout, and Tetris, and judging by the video below it’s surprisingly playable.

Now you might look at this console and wonder what the big deal is. After all, there are plenty of similar designs to be found, and it’s nothing new. Of course, it’s a neat project for any hacker or maker, but we can see that this would make a great starter project for the younger person in your life who wants to try their hands at building something electronic. All through-hole construction for easy soldering, and a neat game at the end of it all.

He’s posted a full write-up of the design process as well as the hackaday.io page linked above, so if you fancy building one yourself there’s nothing to stop you too squeezing 64 bits of graphical goodness from an Arduino.

This isn’t the first Arduino game we’ve shown you here at Hackaday, we’ve unmasked the secrets of the Arduinocade, featured another handheld Arduino game with an LCD screen, and a beautifully coded console using a TFT among many more.

[Rodot] wrote in to tell us about the Gamebuino, a very nicely designed and easily reproducible version of his handheld Arduino gaming console. We originally featured [Rodot's] Arduino based gaming console over a year ago.

With the Gamebuino, you too can build your own games and gaming hardware around the Arduino. While there is a lot of information currently missing from the site’s Wiki, such as the layout and game code, [Rodot] plans on making everything open source. The console includes a rechargeable lithium battery, a micro SD card, and I2C expansion connectors. This is one project to keep an eye (and two hands) on, especially since a full game library is going to be provided, letting you easily create your own games. See what the console can do in the demo video after the break.

It would be amazing so see some old Game Boy games ported to run on the Arduino, or maybe one of our readers can make an Game Boy emulator for the Arduino!
