Turning A Toy Game Boy Into A Real Game Boy

In the world of children’s toys there are many offerings which are meant to look like devices used by older kids or even adults, with the Fisher Price Laugh & Learn Lil’ Gamer toy bearing quite the resemblance to Nintendo’s iconic Game Boy. Although this factoid could be filed away as amusing trivia before passing said toy to a child for its requisite physical abuse by said child, a purported adult can still have a lot of fun with this toy by modding it into a real Game Boy, as [KOUZEX] recently did.

Part of the challenge here is to not just treat it as an unconventional replacement shell for a genuine Game Boy, but to retain as much of the child toy’s look and feel as possible. This includes things like buttons and even the weird sliding blocks on the side.

For the functional components a Game Boy Color with a busted screen was chosen as a donor, with the GBC mainboard fitting almost perfectly inside its new shell. Wires were then soldered to bridge Nintendo’s PCB with the toy’s PCB to make the original buttons and speaker work. After blowing a fuse on the GBC mainboard due to likely some power back feeding, the toy’s PCB had its non-essential parts stripped, but fortunately without further damage to the grafted in electronics.

Most of this mod is quite straightforward, just with some creativity required to add a Select and Start button as these were notably absent from the original. The new, rather large replacement OLED screen is a nice upgrade too and actually fits pretty well with the chunky look of the child’s toy. Even as mostly a joke mod, it seems surprisingly functional.

RC Telemetry Board Lets Virtual Crewmember Help You Race Better

Logging and telemetry in remote controlled racing is a great thing, and not only does [jwachlin]’s Open RC Spotter do a fantastic job of that, it has quite a few clever tricks up its sleeve that make it extra special.

Open RC Spotter is an ESP32-based hardware platform for high performance RC car racing that reads from various sensors (including IMU, GPS, temperature, battery, and IR receiver for IR lap beacons) to create a filtered stream of readings that include position, velocity, lap time, battery voltage, and more.

Got RC car telemetry? Feed it to a virtual race engineer for real-time feedback.

This data gets logged to an SD card, but can also be broadcast wirelessly via ESP-NOW to a receiver that can in turn send it over serial USB, or do whatever else one wishes. There’s also a neat feature that fires up a temporary WiFi access point on demand so log files can be downloaded with a web browser, no need to hook up a cable.

So far, so cool. But there’s still another nifty feature. [Update: originally the project had a link to the sim racing companion application Crew Chief. The developer clarified that at this writing, Open RC Spotter only supports its own Open RC Crew Chief application and not the similarly-named Windows sim racing assistant.] Open RC Spotter supports the Crew Chief telemetry protocol. Crew Chief is a piece of free Windows software that serves as a companion application for sim racing. It acts as a virtual race crew member, providing spoken information based on live telemetry read from supported racing sims.

Since Open RC Spotter supports the same telemetry format, one can use the virtual race engineer with RC car racing by simply feeding Open RC Spotter‘s serial data to the Crew Chief application. The RC telemetry data isn’t as rich as what comes from the racing sim APIs, but it’s more than enough to be useful.

People come up with all kinds of neat ideas when it comes to RC racing, and most of them depend on having access to good data. For example, a load cell in the steering mechanism can provides the data for force-feedback steering. We’ve even seen LiDAR and a depth camera used to automatically compute optimal racing lines.

World’s Biggest RC A380 Is A Big Deal

RC planes are a lot of fun, and the bigger the better! [Ramy RC] has built the world’s biggest RC A380.

At 29 ft (8.83 m) long, with a 32 foot (9.75 m) wingspan, and weighing 800 lb (362 kg), this 1/8 scale jumbo jet is not your typical model. The fuselage is built from CNC cut EPS foam layed up with fiberglass on the outside and carbon fiber inside. The wings have a combination of carbon, aluminum, foam, and wood components to handle the aerodynamic loads.

The attention to detail is wild. Instead of painting the windows, each one is an actual hole in the plane with a 3D printed window frame and acrylic window. You can actually see one falling out of the plane in the video below. An Airbus mechanic in the comments even notes the landing gear door order of operations are identical to the real thing.

If [Ramy] looks familiar, perhaps you remember his previous A380 build? Much like the 747, the full size A380 is no longer in production, but they can run on cooking oil while they’re still flying.

A Quantum Magic 8-Ball

If you ever cracked open one of those Magic 8-Ball toys, you found little more than a polyhedron floating in some dark-colored fluid. It was a quasi-random way of asking the universe to answer crucial questions like “will Mom and Dad get a divorce?” and “does Bethany like me?” even if the results were seldom accurate (sorry about your parents, kid). If you want a more reliably random 8-ball that is not even slightly more truthful, you might like this recent build from [David Noel Ng].

The concept is simple enough — leverage quantum effects that provide truly random results to seed run a random number generator that determines the outcome of a software magic 8-ball. [David] tried a few ways to build something along these lines, and eventually settled on a setup that he felt suited the task at hand.

In the final rig, a light source spits out photons, and is attenuated to the point where effectively only one photon is running through the light path at a time. Each photon passes through a beam splitter, and either passes through the mirror and hits photomultiplier A, or bounces off and hits photomultiplier B. This creates a truly random yes/no result for every photon that passes through. [David] does a great job of explaining the low-level physics at play, as well as the supporting electronics and code that turns this into a usable magic 8-ball that actually answers questions.

We’ve seen other magic 8-ball builds before, too. Few come with quite the same tactile wonder created by the original toy, but they nonetheless do the job of answering questions that are too frivolous to take to a tarot reader or local divining bog witch. If you’re whipping up your own way to deduce the wills of the fates, don’t hesitate to let us know on the tipsline.

The image on the right is of a much smaller and less detailed set of miniatures. The figures's proportions are a little more uncanny and feel like a low budget Disney rip-off.

How Did They Make View-Master Slides?

The basics of producing a stereophotograph of real life places were well-established by the time the View-Master arrived, but producing images of imaginary scenes was a bit more involved. [View Master Travels and Peter Dibble] took a look at how the fairy tale and media tie-in reels may have been made.

Starting with simple dioramas, View-Master eventually developed an entire team to work on fairy tales. One of the most influential members was sculptor [Florence Thomas]. She was instrumental in updating many of the original fairy tale reels from small scale miniatures to 1/6 scale dioramas for the scenes. Unfortunately, the department was eventually cut and all the original miniatures thrown away.

Before VCRs, View-Master was the primary way people could interact with their favorite TV shows and movies when they weren’t being broadcast. TV shows could be photographed while in production in Hollywood with a stereo camera giving great visual detail. Some cartoon and movie reels were less engaging, having been made from promotional images, giving more of a paper cutout appearance rather than “real” 3D. In either case, many of these visual techniques have been lost with little documentation on how they were achieved.

We previously covered [View Master Travels and Peter Dibble]’s History of the View-Master and how you can digitize the disks for posterity.

Building A 1:150 Scale Toyota ProBox Micro Remote Control Car

Although in our imagination those scale models of cars certainly can drive and steer just like their full-scale counterparts, there’s something incredibly satisfying about watching them truly come to life. Here [diorama111] is an absolute master at the craft, with the most recent conversion of a 1:150 Toyota Probox car model once again demonstrating these skills with casual ease.

We previously covered such conversions, with another recent one in 2024 involving another 1:150 scale model. That particular one demonstrated driving around on scale model roads, which shows a good practical use of this conversion if you want to have e.g. a scale model town with cars that actually drive around.

In the video you can see how first the base of the scale model has a tiny 25 mAh Li-polymer battery installed, along with two motors, one for steering and one for driving using a rod-linkage system and a lead screw.

The tiny gears used were salvaged from mechanical watches, with photoreflectors keeping track of the driving and steering positions. Remote control is done by infrared, with a tiny SMD IR receiver module in the car, while charging and programming of the MCU is done via terminals installed on the bottom.

In the final part of the video the car is demonstrated driving around, with working head- and rear lights, as well as blinkers and stop lights, including the top rear one. In the video description links are provided to the various schematics and software on Google Drive for those who are feeling like a fun Sunday afternoon project.

Goddard The Robot Dog Brought To Life

There’s not much more nostalgic for many than good ole’ Jimmy Neutron. This was true for [Kiara], who saw the gorgeous pupper Goddard and wanted him for herself. Of course, there was no solution other than to make an animatronic version of the robot dog.

Starting with some files ripped from a Jimmy Neutron GameCube game, Goddard was designed digitally before being printed in life size. Of course, for a true reproduction of the robot dog, the parts had to be prepped and painted in the iconic chrome and purple. A real plasma ball was used for the brain, and linear actuators were used for the legs. The head was able to be moved around similarly to professional animatronics using fishing line and servos. Put together the entire finished pup, looks incredible.
