Building an arcade cabinet seems to be a rite of passage for many hackers and woodworkers. Not that there is anything wrong with that: as this series of posts from [Alessandro] at boxedcnc shows, there is an art to doing it well.
His final build is impressive, with quality buttons, a genuine-looking banner, and even a coin slot so he can charge people to play. His build log covers both the carpentry and electronic aspects of the build, from cutting the panels to his own code for running the coin acceptor that takes your quarter (or, as he is in Italy, Euro coins) and triggers the game to play.
To extract money from his family, he used the Sparkfun COM-1719 coin acceptor, which can be programmed to send different pulses for different coins, connected to an Arduino which is also connected to the joystick and buttons. The Arduino emulates a USB keyboard and is connected to an old PC running MAME with the Attract Mode front end. It’s a quality build, down to the Bubble Bobble banner, and the coin slot means that it might even make some money back eventually.
At first, we thought we were having deja vu, but then we saw this video embedded below. [Thijs Eerens] is a creative technologist (dare we say, a “hacker”?) who builds giant-scale games for a living. For the Lowlands festival in the Netherlands, he contributed to the build of a huge Pong game that looks as big as a cinema screen.
The paddles appear to be controlled by pulling ropes, and the “ball” is driven around on a system of wires and stepper motors. Code running in the background tracks the player paddles, drives the ball, and keeps score. From the video, there seem to be sound effects involved. It looks like a lot of fun.

[buildxyz] had no opposition to his kids playing video games, but wanted something that offered a bit more parental control, a larger game selection, and was maybe a little more contained than a modern game console.
So, in his multi-part build log, he goes through all the steps of making a Raspberry Pi into a kid friendly wall-mounted game console. The frame is made from Baltic Birch plywood, and the edges look cool when stained. The display is an old HP monitor, and the speakers are simple beige bricks from the thrift store. The controllers hook into a USB hub on the front. It’s not a complicated build, but it’s very well done.
The coolest feature, from the parent’s point of view, is the combination lock on the front. A rotary encoder surrounded by NeoPixels provides the input and feedback. Depending on the code [buildxyz] inputs his children can receive different periods of dopamine hits, and if he enters a special code for occasions like birthdays, unlimited play time becomes available.
We hope he’s prepared to have the only four year olds who can crack safes on the block. The build looks awesome, and there’s not really a commercial product out there to match it. Watch the video.

The Hackaday 10th anniversary was an awful lot of fun, and part of what made it awesome was all the cool things that the community brought to the event. We hadn’t really had a chance to get down to meet the guys from TwoBitCircus before now but they were more than happy to bring along their excellent Hexacade machine. The 6-player custom built arcade game that was an absolute blast!
After the party TwoBitCircus’ fearless leaders [Brent Bushnell] and [Eric Gradman] invited us over to their space for a quick look at their workshop, and to give us a personal invite to the Hacker Preview day for their upcoming STEAM Carnival. No this isn’t Steam as in Steam-punk, but STEAM as in Science Technology Engineering Art and Mathematics.
Their space is really quite amazing, part of The Brewery Art Colony near downton Los Angeles. The building is actually an old steam power plant with incredibly high ceilings. The TwoBitCircus crew is now about 30 people all building interactive games and art pieces for events. They call themselves a digital circus and a lot of their work harkens back to old carnival games of yore with a new digital twist.
[Eric] and [Brent] spared a few minutes to give us a quick run down of what sort of games to expect at the STEAM Carnival. There will be a wide array of entertainment: giant marble runs controlled by see-saws, whack-a-mole/twister mashups on huge glowing button walls, laser based foosball, and the more extreme immolation dunk tank! It will be a most entertaining and educational event. The main public days are on the weekend of 25th – 26th of October, but there is an invite only hacker preview for the local community on Thursday October 23rd which we will be attending. If you’d like to go to the main event, use the code HACKADAY for $5 off the ticket price of $25.
What was most interesting about TwoBitCircus for me as a maker of things was how these guys have turned their hobby into a thriving events business. Brent tells us that they’ve been at this for 8 years now and the company has been around for 3. They’re doing pretty well too, making incredible things for some of the biggest companies around. This really is the best possible job for any inventive hacker sort, building crazy stuff all day for people to play with! I left the place feeling incredibly envious.
Check out the photos below for some impression of the sort of craziness you might see at the carnival!

Star Wars: Yoda Stories was released by LucasArts in 1997 to minimal critical acclaim. As IGN said, “like Phantom Menace proved, just because it’s Star Wars doesn’t mean it’s good.” This didn’t stop [Zach] from playing it, and years later, taking an interest in reverse engineering the game.
[Zach]’s reverse engineering of Star Wars: Yoda Stories (google cache) takes a look at the game’s data file. This binary file is parsed by the game at run time to extract sound effects, sprites, and map tiles. Perhaps the best known game data file type was Doom’s WAD file, which had purpose built editing programs from third parties.
After a quick look at the data file in HxD, [Zach] began writing scripts in C# to extract different sections of the data file. Once the sections were found, more code was used to apply a color palette and generate bitmaps.
In the end, [Zach] managed to get a couple thousand tiles of the game’s data. He found some interesting ones, such as the sports car that he replaced the X-Wing with in his mod. The engine for an earlier Lucasarts game, Indiana Jones and His Desktop Adventures, should be very similar, and once we find the Mac install disk and a copy of ResEdit, we’ll post something on Hackaday.io.
Here’s a cool hack for those of you wishing to play some retro multiplayer SNES games online!
[Michael Fitzmayer] is a resident hacker at shackspace; der hackerspace in Stuttgart. He’s come up with this clever little ethernet adapter network-bridge that can share local controller-inputs over the internet. The entire project is open-source, and readily available on github. It’s still in the early stage of development, but it is already fully functional. The firmware is small and will fit on an ATmega8, and by the looks of the component list it’s a fairly easy build.
He’s even integrated a switch mode (hold B and Y during boot), which avoids trying to figure out which controller will be player one! After all, don’t you remember untangling the controller cords, trying to figure out which one is which?
We know you had a favorite controller and would give the other “crappy” one to your guest.
Example video is after the break.

Hyperrealistic graphics may be the standard for gaming, but Game of Light (Warning: Loud video volume) is a welcomed detour into vivid, low-res delight. Built for a course at the University of Oslo by [Abdimaalik], [Martin], [Andre], [Eivind], and [Stian], Game of Light has a handful game options, some of which allow up to four players. The build uses eight DE-DP14211 LED dot matrix boards, each with 32×16 bi-color LEDs and a built-in HT1632C display controller to handle the multiplexing. They are mounted together to form the 64×64 resolution display.
The box was custom-made out of what we suspect is acrylic, and uses some 3D printed pieces to offset the top from the bottom and to hold components in place. SNES controllers send data to the Arduino, which also runs the games and feeds the display controllers. Buried in the mix are two fans to keep the components cool. Everything is open source, so race to Github for source code and the games.
For another LED matrix project with a lot of gaming potential, check out [Brad’s] PS2 mouse interface that lets him interactively draw in real-time.
