Miniaturizing The Atari 2600 Console

For as popular as Atari was in their heyday, it wasn’t until well after they were on their famous decline that they released their first handheld, the Atari Lynx. In retrospect, competing with the Game Boy was not going to be a recipe for success even without considering their other problems as a company, and as a result was their penultimate console before exiting the market completely. But [Nick]’s most recent project asks what the world would have been like with an Atari handheld from their golden era, and has been working on this miniaturized version of the 2600.

Unlike any modern emulators which can easily handle Atari 2600 games in almost any form factor today, this console is doing it all with as much original hardware as possible. It uses much smaller switches and buttons compared to the original, and omits some other unnecessary hardware for today’s world like the RF modulator. [Nick] has also designed a custom PCB that reduces the overall footprint considerably as well, and has relocated the cartridge port in preparation for its eventual handheld shape. The result is a console using original hardware that’s less than half the footprint of the original.

Although there were around 30 million Atari 2600 consoles sold and the system is unlikely to be a real collector’s item anytime soon, [Nick] makes sure to note that no real 2600 hardware was harmed in this build. And, as far as its handheld nature, this is a stepping stone on the path to that eventual goal. We’ll look forward to an eventual system that integrates a screen and controller as well as a port for the original cartridges. In the meantime, here’s another handheld 2600 that fits completely inside one of those cartridges.

Microdistillery For Microchemistry

Much like radio operators being encouraged to use the least possible amount of power to make a contact, chemists have a similar rule encouraging using the least amount of materials in experiments. Not only is this rooted in economics, but in safety as well; if something goes wrong it’s generally good if there’s not excess amounts of reactants. With modern techniques, though, it’s possible to bring experimental chemistry down to incredibly small scales, and [Marb’s lab] found that they needed a custom built still for these new, diminutive experiments.

The first step is to build the heating component of the still. This is provided with a few custom aluminum parts for the base and a pair of heaters originally meant for 3D printers, with the assembled unit wrapped in insulation. The heater accomodates a 25 mL round-bottom flask. Temperature control of the heating mantle is provided by a controller mounted to a DIN rail which receives power from a 24V power supply, and an additional temperature probe is added to measure the temperature of the distillate. A test run with water shows the small still quickly and efficiently evaporating the water up to a condenser.

Although building a still doesn’t have to be technically difficult, building something this small that’s effective and safe is a bit more challenging than a backyard moonshining operation. Scaling chemical reactions down can often be a challenge but is possible with the right mindset and equipment. We’ve seen miniaturization of many things that we might not have expected including hydrogen production, aluminum smelting, and even the construction of a microscope.

VPlayer Puts Smart Display In Palm Of Your Hand

It’s not something we always think about, but the reality is that many of the affordable electronic components we enjoy today are only available to us because they’re surplus parts intended for commercial applications. The only reason you can pick up something like a temperature sensor for literal pennies is because somebody decided to produce millions of them for inclusion in various consumer doodads, and you just happened to luck out.

The vPlayer, from [Kevin Darrah] is a perfect example. Combining a 1.69 inch touch screen intended for smartwatches with the ESP32-S3, the vPlayer is a programmable network-connected display that can show…well, pretty much anything you want, within reason. As demonstrated in the video below, applications range from showing your computer’s system stats to pulling in live images and videos from the Internet.

Tiny arcade machines on a tabletop

Tiny PONG, Big Ambitions: World’s Smallest Arcade

London, Ontario college student [Victoria Korhonen] has captured the attention of tech enthusiasts and miniaturization lovers with her creation of what might be the world’s smallest arcade machine. Standing just 64 mm tall, 26 mm wide, and 30 mm deep, this machine is a scaled-down marvel playing the classic Atari game PONG. While the record isn’t yet official—it takes about three months for Guinness to certify—it’s clear [Korhonen]’s creation embodies ingenuity and dedication.

[Korhonen], an electromechanical engineering student, took six months to design and build this micro arcade. Inspired by records within reach, she aimed to outdo the previous tiniest arcade machine by shaving off just a few millimeters During the project she faced repeated failures, but viewed each iteration as a step towards success. Her miniature machine isn’t just a gimmick; it’s fully functional, with every component—from paddle mechanics to coding—developed from scratch.

[Korhonen] is already eyeing new projects, including creating the smallest humanoid robot. She also plans to integrate her electromechanical expertise into her family’s escape room business. Her journey aligns with other hobbyist projects pushing the limits of miniaturization, such as this credit card-sized Tetris clone or [Aliaksei Zholner]’s paper micro engines.

3D Printed RC Crane Has Epic 3-Foot Reach

Have you ever looked out the window at traffic and seen a giant crane driving alone the road? Have you ever wanted a little 3D printed version you could drive for yourself without the risk of demolishing your neighbors house? Well, [ProfessorBoots] has just the build for you.

The build, inspired by the Liebherr LTM 1300, isn’t just a little RC car that looks like a crane. It’s a real working crane, too! So you can drive this thing around, and you can park it up. Then you can deploy the fully working stabilizer booms like you’re some big construction site hot shot. From there, you can relish in the subtle joy of extending the massive three-foot boom while the necessary counterweight automatically locks itself in place. You can then use the crane to lift and move small objects to your heart’s content.

The video describes how the build works in intimate detail, from the gears and linkages all the way up to the grander assembly. It’s no simple beast either, with ten gearmotors, four servos, and two ESP32s used for control. If you really need to build one for yourself, [ProfessorBoots] sells his plans on his website.

We’ve seen great stuff from [ProfessorBoots] before—he’s come a long way from his skid steer design last year. Video after the break.

2024 Tiny Games Contest: Realistic Steering Wheel Joystick In Miniature

For racing games, flight simulators, and a few other simulation-style games, a simple controller just won’t do. You want something that looks and feels closer to the real thing. The major downsides to these more elaborate input methods is that they take up a large amount of space, requiring extra time for setup, and can be quite expensive as well. To solve both of these problems [Rahel zahir Ali] created a miniature steering wheel controller for some of his favorite games.

While there are some commercial offerings of small steering wheels integrated into an otherwise standard video game controller and a few 3D printed homebrew options, nothing really felt like a true substitute. The main design goal with this controller was to maintain the 900-degree rotation of a standard car steering wheel in a smaller size. It uses a 600P/R rotary encoder attached to a knob inside of a printed case, with two spring-loaded levers to act as a throttle and brake, as well as a standard joystick to adjust camera angle and four additional buttons. Everything is wired together with an Arduino Leonardo that sends the inputs along to the computer.

Now he’s ready to play some of his favorite games and includes some gameplay footage using this controller in the video linked below. If you’re racing vehicles other than cars and trucks, though, you might want a different type of controller for your games instead.

Miniature Concrete Hoover Dam Is Tiny Engineering Done Right

Growing up, we got to play with all kinds of things in miniature. Cars, horses, little LEGO houses, the lot. What we didn’t get is a serious education with miniature-sized dams. This recreation of the glorious Hoover Dam from the [Creative Construction Channel] could change all that for the next generation.

The build starts with the excavation of a two-foot long curve in a replica riverbed. A cardboard base is installed in the ditch, and used as a base for vertical steel wires. Next, the arch of the dam is roughed out with more steel wires installed horizontally to create a basic structure. The cardboard is then be removed from the riverbed, with the steel structure remaining. It’s finally time to pour real concrete, with a foundation followed by the main pour into foam formwork. The dam is also given 3D printed outlets that can be opened to allow water to pass through — complete with small gear motors to control them. The structure even gets a little roadway on top for good measure.

The finished product is quite impressive, and even more so when the outlets open up to spill water through. Such a project would be great fun for high school science students, or even engineering undergrads. Who doesn’t want to play with a miniature scale dam, after all? Bonus points if you build an entire LEGO city downstream, only to see it destroyed in a flood.
