[Greg] wanted to build a MAME cabinet. Not one of those monsters that take up a bunch of floor space, mind you: this one would be table-top size. He admits he could have made his game system out of new, currently available, off the shelf parts, but part of the design goal was to reuse old hardware that was kicking around. It was important to [Greg] to keep unnecessary waste out of the landfill.
An old PC motherboard was pulled out of an old desktop. It’s not fast enough for use as an everyday computer but it will be totally sufficient for a MAME machine. The project’s screen is an old 13 inch Gateway CRT computer monitor. Notice that it is turned 90 degrees so that it is taller than it is wide. This screen orientation lends itself better to certain types of games. The monitor’s plastic casing was removed before some measurements were taken. SketchUp was used to plan a basic idea of the cabinet.
The controls consist of a joystick and 4 buttons. During past projects, [Greg] has had experience with the least-expensive arcade controls available on eBay. Well, you get what you pay for. This time around he ponied up the extra cash for some high quality controls and is satisfied with the purchase. These buttons were wired straight into a PS/2 keyboard so the computer does not know the difference between the keyboard keys or recently added controls… another great re-use of old obsolete hardware.
The cabinet is made from MDF, glued and screwed together. The limited wood working tools available wasn’t a show stopper for this dedicated builder. For example, the square hole for the joystick was made by removing most of the material with a spade drill bit before using a chisel to clean up the edges. Doing it this way was a little tedious, but you have to do what you have to do sometimes. Once the entire cabinet was finished, several coats of paint were added in a yellow and blue water-theme. Black rubber molding finishes off the edges of the cabinet nicely.
Moore’s law is the observation that, over the history of computing hardware, the number of transistors on integrated circuits doubles approximately every two years. This rapid advancement is certainly great for computing power and the advent of better technology but it does have one drawback; otherwise great working hardware becomes outdated and unusable. [Dave] likes his flight simulators and his old flight sim equipment. The only problem is that his new-fangled computer doesn’t have DA15 or DE9 inputs to interface with his controllers. Not being one to let something like this get him down, [Dave] set out to build his own microcontroller-based interface module. He calls it the Multijoy_Retro.

Video games are amazing these days. Cinemagraphic game play, incredible accelerated graphics, you name it. The average tabletop board game though, has not received the benefit of all this technology. [Marcel] hopes to provide some options for changing that with Lichtspiel, an Interactive Digital Boardgame. Lichtspiel uses a Philips Pico-Beamer projector to project the game board onto a white surface. A camera (either a Raspberry Pi camera module or a Logitech USB webcam) then picks up the players interactions with the game board. Actual interaction is done with small black chips. When a player moves their chip, the vision system sends the x,y coordinates main processor. The game then changes based upon the chip position. [Marcel’s] video shows two demonstrations, a matrix style board game simulation for two and a co-operative asteroids style game. In the asteroids style game one player moves the ship while the other aims the weapons.
We can’t help but see the similarities between this system and the board game demos for castAR , though we feel they fill different niches. Lichtspiel does away with 3D, and by doing so doesn’t require projection glasses to play. Lichtspiel definitely has possibilities. We’d love to see [Marcel] open up his software design so that it can be further developed.

[Petri] wrote in to show off the 8-bit gaming system and original platformer which he and [Antti] developed. Don’t get us wrong now, it’s impressive that the duo were able to put together what looks like a very interesting game. But we’ve seen many industry-leading video games developed with just one or two people (we’re thinking all the way back to the days of Atari). Nope, what’s most interesting to us is that the console is also their creation. We should note that the title screen was the work of their friend [Juho].
Take this with a grain of salt, as the bottom right image in the vignette obviously includes an Arduino. But isn’t it a testament to the state of open hardware and the sharing of knowledge through the Internet that this is even possible on the hobby level? And just because we call it “hobby” doesn’t mean you have to lower your expectations. This thing is full featured. Watch the clip after the break to see the ATmega328 driving a 104×80 resolution screen with a 256 color palette, while using four audio channels for the chiptunes. The thing even utilizes an original NES controller port for user input.
And for those of you who are thinking we’ve seen the same thing before, we never get tired of seeing projects where a lot of hard work has obviously paid off!

As we read [Adam]’s writeup for an extremely tiny video game system through coke bottle glasses, we’re reminded of the countless times we were told that sitting, ‘too close to the Nintendo’ would ruin our eyes. We’ll happily dismiss any article from a medical journal that says there was any truth to that statement, but [Adam]’s tiny video game system will most certainly hurt your eyes.
A few years ago, Atari sold keychain-sized joysticks that contained classics such as Pong, Breakout, Centipede, and Asteroids. [Adam] apparently ran into a cache of these cool classic baubles and immediately thought of turning them into a stand-alone video game system.
For the display, [Adam] used a CRT module from an old Sony Handicam. These modules had the right connections – power, ground, and composite video input – to connect directly to the Atari keychain games. The result is a video game that’s even smaller than a postage stamp. The picture above shows the tiny CRT next to a 25mm postage stamp; it’s small by any measure.
Casemodders extraordinaire [Downing] and [Hailrazer] are known for their fabulous builds that put just about every gaming console into a portable hand-held format. Everything from a Game Cube to N64s and a Sega Genesis have been conquered by the two, and for the last year they’ve been putting their heads together to make the best solution to portabalizing console gaming forever. It’s called the Cross Plane, and puts just about everything with an HDMI connection in the palm of your hand.
The build began as one of [Downing]’s more ambitious projects. He imagined a system that could play nearly every retro game on a small handheld device. After finishing this build, he set up a Kickstarter and called up his friend [Hailrazer] to get some feedback. Just hours before the Kickstarter launched, [Hailrazer] suggested making a device for modern consoles. [Downing]’s pride and joy was scrapped, but out of its ashes arose the Cross Plane.
Inside the Cross Plane is a wireless HDMI receiver and a 7″ 720p display. This, along with a few buttons and analog controls, allow the Cross Plane to serve as a remote display and controller for an XBox 360, Playstation 3, and even a PC, for all that retro emulator goodness.
It’s a really, really cool project, and since the dream of an open Wii U controller seem to have died, we’re thinking this could be a great controller for an FPV quadcopter or other remotely operated vehicle.
Mini arcade cabinet builds are fairly common, but we’ve never seen anything like [Jurgen]’s mini vector Asteroids cabinet that takes an original Asteroids circuit board and a true vector monitor and shrinks it down to table top size.
Unlike the raster monitors of a later generation’s arcade games, the original Asteroids cabinet used a vector monitor just like one would find in an oscilloscope. [Jurgen] found the perfect CRT in, of all places, a broken Vectrex console. The video circuitry in the Vectrex was rather primitive and the beam deflection was far too slow for the video signals generated by the Asteroids PCB. To get around this, [Jurgen] added a custom XY driver board. While the Asteroids game – and other vector Atari games – were designed for a screen with 1 MHz of bandwidth, [Jurgen] found that 300 kHz was ‘good enough’ to display proper Asteroids graphics.
While the cabinet isn’t a miniaturized version of any proper cabinet, [Jurgen] did manage to build a rather nice looking case for his luggable version of Asteroids. The exposed PCB on the back is a great touch, and an awesome project for any ancient video game aficionado.
