6 Foot Tall Fire Breathing Piranha Plant From Super Mario Brothers

May 9, 2013 by Caleb Kraft 32 Comments

I always thought it would be cool to build a giant fire breathing piranha plant. I never really came up with an excuse to do it though. Eventually, I just decided I didn’t really need an excuse, and thus it was born.

The plant itself is pretty much just foam and cardboard. You can see the construction process in the video, it was really easy, but a little time consuming. I wanted to go with a bit of a crazy, hyper stylized look, so it is covered in veins and has these insane looking wrinkly lips. The plant itself would be a fun thing just to have around the house. Actually, I may turn it into a lamp.

The fire systems were very much trial and error.

Beautiful Modded NES For The 25th Anniversary Of Mega Man, Plus Bonus Interview!

May 8, 2013 by Caleb Kraft 16 Comments

Today I had the pleasure of interviewing [PlatinumFungi] about this fantastic NES mod he did. This year is the 25th anniversary of the first Mega Man video game. Unhappy with the current celebratory actions of capcom, [PlatinumFungi] set out to create something he felt was worthy. He managed to pull that off pretty well.

The NES you can see in the video is fantastic looking. It has a beautiful shiny automotive finish, supplied by [Custom NES Guy] and a pixel perfect backlit Mega Man on top. Additional enhancements are stylized decals on the front of the game bay and matching labels on the sides and back. The cartridge is even illuminated while it is in place.

Check out some pictures after the break!

Drop-in Pcb Makes Nintendo Four Score A USB Joystick

April 21, 2013 by Mike Szczys 12 Comments

The Nintendo Four Score was a controller attachment for the original Nintendo Entertainment System which allowed you to use four controllers at one time. [Simon Inns] wanted to use some original NES controllers on his computer so he developed a drop-in replacement board that converts the device to USB.

As we’ve seen with other NES controller hacks, the hardware uses a simple parallel to serial shift register to deliver key-presses to the console. This means that reading four controllers at a time is no different than shifting in data to a microcontroller from the four different sources. The remaining portion of the problem is providing a USB connection that enumerates the device as a joystick. We’ve seen a bunch of USB projects from [Simon] so it’s no surprise that he was able to pull it off.

He went with the ATmega16U2 which has built-in support for USB. [Simon] wrote the code so that although there is only one USB cable, each of the four controller ports will appear as a separate USB joystick on the computer. To button up the project he carefully measured the original board and laid out his own version so that it fits the footprint of all the original components as well as the mounting brackets on the case. Top notch [Simon]!

SNES Headphones Scream Out For Bluetooth Control

April 1, 2013 by Brian Benchoff 22 Comments

Here’s a build that just exudes nerd cred. It’s an SNES controller modified into a pair of headphones, straight from the workshop of [lyberty5].

The build began by stealing a controller from a PAL SNES and carefully dremeling the buttons and d-pad loose from their plastic frame. The PCB was cut in half, and the remaining plastic was carefully crafted into round speaker enclosures with the help of some epoxy. hot glue, and possibly a few pieces of styrene.

The result is a perfectly formed pair of SNES headphones, with a build quality right up there with the best case mods we’ve seen. Unfortunately, while the buttons are still attached to the PCB, they don’t do anything. We’re thinking a small Bluetooth adapter – or even repurposing a set of Bluetooth headphones with volume and play controls – would be a wonderful use for the 20-year-old, candy-like buttons.

Still, an awesome build, and [lyberty5] really shows off his craft by constructing these wonderful headphones. You can see the time-lapse of the build after the break.

Mining Bitcoins On A Nintendo

March 25, 2013 by Brian Benchoff 25 Comments

NES

His friends know [gbg] as an aficionado of just about anything with a 6502 processor in it. He’s also interested in bitcoins. A while back, a friend asked if it would be possible to mine bitcoins with an old Nintendo Entertainment System. While this suggestion was made in jest, it’s not one of those ideas anyone can let go of easily. Yes, it is possible to mine bitcoins with an NES, and [gbg] is here to show us how.

Mining bitcoins is simply just performing a SHA256 hash on a random value from the bitcoin network and relaying the result of that calculation back to the Internet. Of course this requires an Internet to NES bridge; [gbg] brought in a Raspberry Pi for this task. There’s the problem of actually getting data into an NES, though, and that’s something only a USB CopyNES can handle. After doing some 32-bit math, the NES sends this out to the Raspberry Pi and onto the bitcoin network.

When you consider that even a high-end gaming computer has little chance of mining a bitcoin in any reasonable amount of time, there’s little chance RetroMiner will ever be able to mine a bitcoin. It’s all random, though, so while it’s possible, we’ll just appreciate the awesome build for now.

Hinged NES Case Hides An Integrated LCD Screen

March 12, 2013 by Mike Szczys 28 Comments

We’ve sure been seeing a lot of original NES cases used in projects lately. This time around the thing still plays the original cartridges. This was one of the mains goals which [Maenggu] set for himself when integrating the LCD screen with the gaming console. There is a quick video clip which shows off the functionality of the device. It’s embedded after the break along with a few extra images.

To our eye the NES looks completely unmodified when the case is closed. The cartridge slot still accepts games, but you don’t have to lower the frame into place once that cartridge has been inserted. The image above shows a ribbon cable connecting the top and bottom halves of the build. It routes the signals for both the LCD screen and the cartridge adapter to the hardware in the base. He mentions that he used the original power supply. We’re not sure if the original motherboard is used as well or if this is using some type of emulator.

Hacking A PAL SNES To Output 50Hz Or 60Hz With A Single Switch

March 1, 2013 by Mike Szczys 10 Comments

snes-pal-ntsc-mod

[Derecho] grabbed a PAL format Super Nintendo but wanted to make it play nicely with a 60 Hertz NTSC screen. His hack added a single switch to choose between 50 Hz and 60 Hz.

Take a look at the image above to see his alterations to the mainboard. The jumpers soldered to the two chips at the top are by far the trickiest part of the project. Each of the pins he soldered to needed to first be lifted from the PCB pad so that they no longer make contact with the etched traces. The technique he used involves heating the pin with an iron, then gently lifting it with a pin or a razor knife/blade. If you’ve got some experience populating SMD boards with a handheld iron this shouldn’t prove too difficult. The rest of the hack involves adding a 3-position switch (along with a 2k2 resistor) to choose between output modes based on what format game is being played.
