What’s the smallest controller you’ve ever used? [BitBuilt] forum user [Madmorda] picked up a cool little GameCube controller keychain with semi-working buttons at her local GameStop. As makers are wont to do, she figured she could turn it into a working controller and — well — the rest is history.
This miniaturized controller’s original buttons were essentially one piece of plastic and all the buttons would depress at once — same goes for the D-pad. Likewise, the original joystick and C-stick lacked springs and wouldn’t return to a neutral position after fidgeting with them. To get the ball rolling, [Madmorda] picked up a GC+ board — a custom GameCube controller board — just small enough to fit this project, eleven hard tact switches for the various buttons, and two squishy tact switches to replicate the original controller’s L and R button semi-analog, semi-digital functionality.

Most of us would probably like to have an arcade cabinet at home, but it’s hard to justify the space they take up. Sure it’s an awesome conversation starter when friends are over, and you might even play it regularly, but at some point you’ll look over at the corner and realize there’s probably something more practical you could be doing with that particular section of the room.
Perhaps the solution is to just make a smaller one. You could do one at half scale, or even desktop sized. But why stop there? Why not make one so small that you could put the thing in a drawer when you don’t need it? While it might be more of an academic experiment than a practical entertainment device, [RedPixel] has managed to create just such an easily concealable arcade cabinet out of a Pi Zero and laser cut wood. At only 83 mm high, this may well be the smallest functional arcade cabinet ever made (at least for now).
All of the cabinet parts were drawn in Inkscape and cut out of 3 mm plywood. The buttons and joystick are wired directly to the Pi Zero’s GPIO pins and configured with Adafruit-retrogame. The display is a SPI ILI9163, which [RedPixel] previously documented on his site.
The Pi is running the ever-popular RetroPie, which allows this tiny arcade cabinet to emulate 1000’s of console and arcade games, assuming you can deal with the controls anyway. While [RedPixel] has uploaded a video of his lilliputian cabinet running an emulator, there’s no video of him actually playing the thing. While we don’t doubt that it functions as advertised, gameplay on such a tiny array of inputs must be very difficult.
This may be the smallest functional arcade cabinet to date, but it isn’t without challengers. We’ve covered a number of very impressive builds that manage to invoke the look and feel of a hulking coin-up despite fitting neatly on your desk.

How do you classify something that is gigantic and miniature at the same time? LEGO kit 850, from 1977 when it was known as an Expert Builder set, was 210 modular blocks meant to be transformed into a forklift nearly 140mm tall. [Matt Denton] scaled up the miniature pieces but it still produced a smaller-than-life forklift. This is somewhere in the creamy middle because his eight-year-old nephew can sit on it but most adults would demolish their self-esteem if they attempted the same feat.
[Matt] has been seen before building these modular sets from enlarged LEGO blocks, like his Quintuple-Sized Go-Kart. He seems to have chosen the same scale for the pieces and who wouldn’t? If you’re printing yourself a ton of LEGO blocks, it just makes sense to keep them all compatible. Isn’t combing all your sets into one mishmash the point after all? We’ll see what his nephew/co-host constructs after his uncle [Matt] leaves.
In the time-lapse video after the break, you can see how the kit goes together as easily as you would hope from home-made bricks. With that kind of repeatability and a second successful project, it’s safe to say his technique is solid and this opens the door to over-sized projects to which LEGO hasn’t published instructions.
Hackaday is bursting with LEGO projects, K’Nex projects, and even Erector set projects.

In a clever bit of miniaturization, [JediJeremy] has nearly completed a gyro-mouse controller for a Raspberry Pi Zero! Ultimately this will be a wearable Linux-watch but along the way he had some fun with the interface.
Using the MPU6040 gyroscope/accelerometer card from a quadcopter, [JediJeremy] spent a week writing the driver to allow it to function as a mouse. Strapping an Adafruit 1.5″ PAL/NTSC LCD screen and its driver board to the Zero with rubber bands makes this one of the smallest functional computer and screen combos we’ve seen. Simply tilt the whole thing about to direct the cursor.
It presently lacks any keyboard input, and [JediJeremy] has only added a single button for clicking, but look at this thing! It’s so tiny! In his own words: “I think this is the first computer that I can accidentally spill into my coffee, rather than vice versa.”

Building a MAME machine around a Raspberry Pi has been the standard build for years now, and tiny versions of full-sized arcade machines have gone from curiosity to commonplace. [
The entire enclosure is 3D printed, and most of the electronics are exactly what you would expect: A Raspberry Pi, 2.5″ LCD, and a battery-powered speaker takes up most of the BOM. Where this build gets interesting is the buttons and joystick: after what we’re sure was a crazy amount of googling, [diygizmo] found something that looks like a normal arcade joystick, only smaller. Unable to find a suitable replacement for arcade buttons, [diygizmo] just printed their own, tucked a tact switch behind the plastic, and wired everything up.
Add in some decals, paint, and the same techniques used to create plastic model miniatures, and you have a perfect representation of a miniature arcade machine.
[José Manuel Hermo Barreiro] has spent many many hours crafting these tiny engines from hand. Every single piece is custom made specifically for the engine it is going onto. He has created aircraft engines, car engines, and marine engines that all actually run and are the smallest of their kind in the world.
At one point in this video he stands in a room with several engines lined up, all running smoothly and considers that there are possibly over 15,000 hours of work right there in front of him.
Here’s a video specifically about the 12 cylinder construction.
Meet [Ray Gascoigne]. He’s a ship builder. Well, he builds ships in bottles. He’s been doing it for years and years and years and you can see it in his hands. The details are fantastic on the ships, but I really love hearing about the tools. He talks about how much things have changed over the years from having to build your own specialized tiny drill bits from broken needles to being able to just walk right down to the store and buy some.
The part that I found most interesting is this video, as amazingly beautiful as it is, never shows the insertion and erection of a full ship.
