Building An Energy Sword Replica From Halo

April 1, 2023 by Lewin Day No comments

A good many of us whiled away the hours of our youths playing Swords Only deathmatch in Halo 2. The Energy Sword, aka the Plasma Sword, was the star of the show, with its devastating glowing blades granting us scoreboard domination. [Arnov Sharma] has now built a quality replica of this science-fiction weapon.

The build starts with a 3D design drawn up in Fusion 360. The parts are then 3D printed, with opaque filament used for the handle and translucent PLA filament for the “blade”. Inside the blade elements are twenty WS2812B LEDs, creating the characteristic glow that made the Energy Sword so tantalizing to find in game. An ATtiny85 is charged with running the LEDs, with the aid of an IP5306 chip to act as a boost converter for the lithium-ion battery supplying the juice.

[Anton] admits that the sword was built for the sole purpose of beautifying his maker space. That’s something we can respect, because we’d love to have one hanging on the wall at home. We’ve featured some other fun gaming replicas before, too.

Building The World’s Largest Nintendo 3DS

March 21, 2023 by Bryan Cockfield 2 Comments

While the Nintendo 3DS was capable of fairly impressive graphics (at least for a portable system) back in its heyday, there’s little challenge in emulating the now discontinued handheld on a modern computer or even smartphone. One thing that’s still difficult to replicate though is the stereoscopic 3D display the system was named for. But this didn’t stop [BigRig Creates] from creating this giant 3DS with almost all of the features of an original console present.

The main hurdle here is that the stereoscopic effect that Nintendo used to allow the 3DS to display 3D graphics without special glasses doesn’t work well at long distances, and doesn’t work at all if there is more than one player. To get around those limitations, this build uses a 3D TV with active glasses. This TV is mounted to a bar stool with the help of some counterweights, and a second touch-sensitive screen courtesy of McDonalds makes up the other display.

The computer driving this massive handheld console runs Citra, and also handles the scaled-up controls as well. To recreate the system’s analog touch pad, a custom joystick tipped with conductive filament is used to interact with a smartphone hidden inside the case. Opposing rubber bands are used to pull the stick back into the center when it’s not being pushed.

Plenty of 3DS games are faithfully replicated with this arcade-sized replica, and as Citra supports various 3D displays, upscaling of the graphics, and the touchscreen interface, almost everything from the original console is produced here. There are a few games that don’t work exactly right, but all in all it’s a remarkable build and, as far as we can tell, the largest 3DS in the world. Don’t forget that even though this console is out of production now, there’s still a healthy homebrew scene to take part in.

Defender Arcade Rebuilt To Settle A Childhood Memory

March 3, 2023 by Arya Voronova 7 Comments

[Jason Winfield] had a nemesis: the Defender arcade machine. Having put quite a number of coins into one during his childhood, he’s since found himself as a seasoned maker, and decided to hold a rematch on his own terms. For this, he’s recreated the machine from scratch, building it around the guts of a Dell laptop, and he tells us the story what it took to build a new Defender in this day and age.

Defender was a peculiar machine — it was in cocktail table format, unlike many other arcade machines of that period. From pictures, he’s redesigned the whole thing in Fusion 360, in a way more desk-friendly format, but just as fancy looking as before.

As for the laptop, gutting it for its mainboard, screen, and speakers was a surprisingly painless procedure — everything booted up first try. A few board-fitted brackets and a swap from a HDD to a USB flashdrive for the OS later, the electronics were ready. As he was redesigning the entire arcade machine anyway, the new design control panel was also trimmed down for ease of use, while preserving the original colorful look.

All in all, an impressive build from [Jason]. After all was set and done, we don’t doubt that he went on to, let’s say, settle some old scores. It’s not the first time we see a desktop-sized arcade cabinet, and you gotta admire the skills making such a machine smaller while sticking to the old-timey aesthetic! Or, perhaps, would you like a cabinet that’s more subtle?

Brand New Colecovision Console – On A Breadboard

March 1, 2023 by Jenny List 4 Comments

The Colecovision console from the early 1980s is probably not the most memorable platform of its era, but it retains a retrocomputing following to this day. The original hardware can be a bit pricey in 2023, so [nanochess] has built one of his own on a breadboard. It’s fully functional from original Colecovision cartridges, and we see it in the video below the break running Frogger.

Behind the mess of wires is a surprisingly simple circuit with only a few logic chips beyond the Z80 processor, the various memory and EPROM chips, and the video and sound chips. We’re told the complexity is considerably reduced by the use of a Texas Instruments TMS9118 video controller instead of a 9918.

Had we been building it we would probably have taken the less brave step of using color coded wires for the various signals, because we remember the fun and games associated with wiring old-style 8-bit computers by hand only too well. But we have to admit that it reminds us of a lost youth working out Z80 address decoder schematics, so it’s very pleasing to see one built today.

If you’re hungry for more Coleco goodness, this isn’t the first home made Colecovision we’ve brought you.

Pushing Crates In 8-bit Color

February 24, 2023 by Bryan Cockfield 6 Comments

Moore’s law isn’t strictly holding anymore, but it is still true that most computing systems are at least trending towards lower cost over time, if not also slightly smaller size. This means wider access to less expensive hardware, even if that hardware is still an 8-bit microcontroller. While some move on to more powerful platforms as a result of this trend, there are others still fighting to push these platforms to the edge. [lcamtuf] has been working to this end, stretching a small AVR microcontroller to not only play a classic video game, but to display it on a color display.

Watch Sony Engineers Tear Down Sony’s VR Hardware

February 19, 2023 by Donald Papp 22 Comments

Teardowns are great because they let us peek not only at a product’s components, but also gain insight into the design decisions and implementations of hardware. For teardowns, we’re used to waiting until enthusiasts and enterprising hackers create them, so it came as a bit of a surprise to see Sony themselves share detailed teardowns of the new PlayStation VR2 hardware. (If you prefer the direct video links, Engineer [Takamasa Araki] shows off the headset, and [Takeshi Igarashi] does the same for the controllers.)

The “adaptive trigger” module responsible for the unique feedback.

One particularly intriguing detail is the custom tool [Araki] uses to hold the headset at various stages of the disassembly, which is visible in the picture above. It looks 3D-printed and carefully designed, and while we’re not sure what it’s made from, it does have a strong resemblance to certain high-temperature SLA resins. Those cure into hard, glassy, off-yellow translucent prints like what we see here.

As for the controller, we get a good look at a deeply interesting assembly Sony calls their “adaptive trigger”. What’s so clever about it? Not only can it cause the user to feel a variable amount of resistance when pulling the trigger, it can even actively push back against one’s finger, and the way it works is simple and effective. It is pretty much the same as what is in the PS5 controller, so to find out all about how it works, check out our PS5 controller teardown coverage.

The headset and controller teardown videos are embedded just below. Did anything in them catch your interest? Know of any other companies doing their own teardowns? Let us know in the comments!

Retro Gadgets: Nintendo R.O.B Wanted To Be Your Friend

February 16, 2023 by Al Williams 20 Comments

Too busy playing video games to have a social life? No worries. In 1985, Nintendo introduced R.O.B. — otherwise known as the Robotic Operating Buddy. It was made to play Nintendo with you. In Japan, apparently, it was the Family Computer Robot. We suppose ROB isn’t a very Japanese name. The robot was in response to the video game market crash of 1983 and was meant to keep the new Nintendo Entertainment System (NES) from being classified as a video game, which would have been a death sentence at the time of its release.

Since you might not have heard of R.O.B., you can probably guess it didn’t work out very well. In fact, the whole thing tanked in two years and resulted in only two games.
