Grab your favorite cartridge and violently blow into the end, because [Dave Nunez] is sending us on a nostalgia trip with his 3D printed portable NES. He takes the typical route of chopping up a Nintendo on a chip (NOAC) retro machine rather than sacrifice a real NES, and opts for a NiMH battery over lithium (which isn’t a bad idea; they can burst into flames if you charge them incorrectly). The battery life is, however, tolerable: 2.5 to 3 hours.
All the components are packed into a custom-made 3D printed PLA enclosure, which [Dave] kindly shares on thingiverse. He also decided to 3D print each of the buttons and their bezels/housings, which he then topped off by cutting acrylic sheets that seal up the front and back. As a final touch, [Dave] slips in some custom art under the acrylic and mounts a printed LED nameplate in the corner.
We’ve seen [Dave's] work at Hackaday before, when he built a one-size-fits-all-consoles arcade controller.
[Callan Brown] wrote in to show us a really interesting NES audio hack. [Callen] decided that he wanted the full Castlevania III audio experience, which (without modifications) can only be had through the original Japanese Famicom console. [Callen] weighed a few adapter options, and instead decided to come up with his own.
The issue is that the Japanese Famicom and the American NES actually have a different cartridge connector. The change in hardware from a 60 pin to a 72 pin connector added “features” like the 10 pins connected directly to the expansion port (used for stuff like the teleplay modem, who knew). The other two additional pins are used by the annoying 10NES lockout chip. While they were at it, Nintendo decided to route the audio path through the expansion connector instead of the cartridge.
This means that the Japanese cartridges can’t pipe sound to the NES audio channel with just a pin adapter. Good news though, after sourcing a pin adapter hidden inside certain NES games (Stack Up, Gyromite), audio can easily just be pulled from the adapter PCB. This requires the more expensive Famicom Castlevania III cartridge (Akumajou Densetsu). To cleanly route the new audio cable out of his front loading NES [Callan] reuses the sacrificial adapter game’s cart to make some kind of unholy hybrid. To round it off [Callan] also goes over steps to flash a translated ROM to the Japanese game.
What difference could an extra two squares and a sawtooth make? Check out the sound comparison video after the jump! Thanks [Callan].

The Queen of Bondo is back again, this time with an adorably small NES portable, the HandyNES.
When last saw [lovablechevy], she had just finished up her build of a Nintenduo, a build that stuffed an NES and SNES into a single box. The Nintenduo was such a clean build it would be a crime to let her talents go to waste, so [Lovablechevy] finished up one of the smallest NES portables we’ve seen.
The build is based on a top-loading NES with a 3.5″ screen. [rekarp]‘s NES2 composite mod was used to get the NES and screen working together. Two LiIon batteries provide 3 hours of play time (with a low battery indicator, natch).
[lovablechevy] also included an AV out so she can connect her HandyNES to a larger CRT screen. Like our old Sega Nomad, this allows for a little two-player action – player one using the HandyNES and player two using an extra controller. Support for the Zapper was also included after modding the Zapper connection to a USB port.
Check out the video walkthrough after the break. To prove that her build isn’t a clone, [lovablechevy] also include a video of herself playing Battletoads past the point where the clones crash. Excellent work from the Queen of Bondo.

[lovablechevy] loves her Retro Duo console, especially since it takes up less space than the NES and SNES it has replaced. There’s a small problem though: the Retro Duo isn’t 100% compatible with her old Nintendo cartridges. Battletoads is a deal breaker for her, so she built Nintenduo, an NES/SNES console that uses all original Nintendo hardware.
The Queen of Bondo began her project with a top-loading NES and the smaller revision of the SNES. There’s a Photobucket gallery showing the innards lovingly placed in their new plastic home.
Not only can [lovablechevy] play classics like Paperboy, Donkey Kong Country, and the Super Mario RPG that are incompatable with the Retro Duo, all the accessories like the Zapper and Power Pad now work.
The finished build is very small; not much bigger than an SNES 2, and is nearly dwarfed by the gigantic NES cartridges. She posted a video of herself trying not to shoot the stupid Duck Hunt dog with her Nintenduo. Check it out after the break.

Reminiscent of [Ben Heck]’s portable and laptop console mods, [Bandit5317] over at Xbox-Scene managed to fit the guts of an original Xbox into a custom-built slim case that measures just 2.5 centimeters thick. In his post, he describes some of the difficulties of cutting down a behemoth Xbox to a third of its original size, such as rewiring a custom IDE cable to avoid the extra 1/16-inch it would take to fold a standard one. The case is hand-crafted, (no laser cutter!) no-frills box made of painted polycarbonate, and man is it sexy. It is built off of a v1.4 motherboard running a third-party BIOS and with a 320GB laptop hard drive. Load up XBMC Media Center and you’ve got the slimmest home theater PC on the block.
Part 2 of Ben Heck’s Wii laptop How-To is up. The first half is all about the little touches, wiring switches, extending connectors, etc. The second half delves into designing the actual unit. Some of the comment’s on Engadget seem to want a full bore step by step build, but fail to realize that he’s really giving them the gold. Very few designers give away their intermediate design steps – But I am reminded of some of the Star Wars movie extras…
