If you grew up playing NES games back in the 80’s, then you know that you had to blow on the NES cartridges to get it to recognize a game. Ahh memories. The one console that strengthened our lungs and our fingers.

Well, one modder is using that nostalgia to turn a profit with a clever mod. Seller nes_harmonica has turned some old NES cartridges into actual working harmonicas and put them on eBay. Right now you can get Dick Tracy, Legend of Zelda and Super Mario 3 with starting bids of just $7.

We all love NES cartridge mods. But here’s the thing. When it looks like a third grader did it, we aren’t really interested. A good mod looks like something that you could potentially buy and something that maybe you can’t do yourself. Sorry, but this misses the mark.

That Duck Hunt cart died for this? This is less of a mod and more of a cut hole and insert cable project. Plus it’s ugly. I don’t mean to be a downer, but this is the red-headed step child of mods right here.

You love the old NES, I love the old NES. We all love the NES. That’s why you need this NES netbook case for $50. Cloth your netbook in something cool and disguise it as an oversized NES controller. Great way to meet girls.

OMG where did you get that NES case? That is like so awesome. Can I go out with you? Basically, with this case you’ve got it made Romeo. Display it proudly, let your netbook wear it loudly. You the man.

Console guitars have been around for awhile, but this one is a real gem. This NES guitar even has the headstock replaced with a cartridge. Though it looks like it would break super easy.

Bust out the old NES guitar and it’s an instant Mario Party. You can play Yoshi’s greatest hits. Flipping open the cartridge slot reveals the standard guitar knobs and the AV out and power ports have been converted accordingly. Super awesome and rocking custom mod.

A complete NES in a cartridge. This NES cartridge casemod holds a complete library of NES games, uses the original buttons, resides inside the Super Mario/Duck Hunt combo cartridge. Awesomeness? I think so.

But that isn’t all it does. It’s also an mp3 player, movie player and an FM radio receiver. It also features video out so that you can play on the big screen if you want. If only the NES had been this small originally.

We all love the old NES cartridges. They bring back memories of hours of fun playing the old console. So we love any excuse to have them back in our lives today. Like with these NES cartridge hard drives.

Etsy seller 8-Bit Memory takes old NES cartridges, stuffs a hard drive inside and just like that Mario is holding your data. It will cost you $120 for 250GB, but he will gladly make any size for you and with any cartridge. For an extra fee of course.

This NES Controller will keep your business cards safe, while acknowledging that you are a proud geek and a Nintendo fan. It’s a business card holder with 2 compartments. The first is for your business cards, the second compartment lets you hold other people’s business cards that you receive when meeting them.

This retro tribute to classic gaming is available from Geek Stuff 4U and for around $31 toward the end of October of 2009.

This beautiful item is the kind of thing that separates the real nerds from the pretenders. The NES controller netbook cover is for true nerds only.

What’s not to love? It looks just like the classic controller, is soft to the touch and keeps your netbook nice and cozy. It’s made of felt, so don’t be afraid to caress and gently stroke it my dork friend.

Like us, you’ve seen plenty of iPhone docks, but have you ever seen one made from an NES Controller? I thought not. This cool NES controller iPhone dock was made by iPhone.fr forum member WCR for his new iPhone 3GS.

We have to admit, the iPhone and the NES controller look great together, like a match made in geek heaven. Great work WCR. If it could just play iPhone games while docked….

So you’re living the life. You have your pimp cane, pimp fedora, Pimp fur coat. Hell, you just laid down several grand on gold teeth. You livin’ large my brotha from anotha mother. For shizzle.

A typical evening for you is cruising down the strip in your gold Cadillac or your Pimp Deville, keeping your stable of fine skankery in line as they do the hustle. A few hours later, you collect the money, making sure they don’t hold out on you. Then it’s off to the crib to chill and drink from your pimp cup and play some PIMPtendo, in it’s sweet sexy zebra skin.

We’ve seen plenty of casemods, but the NES will always give us a warm tingly feeling. The nesPod is the work of flickr user recycledgamer. It’s a gutted NES controller and an iPod mini from around 2004-2005. The back has been cut out for the screen and clickwheel.

And that’s all there is to this mod. Pretty simple. NES in front, iPod in back. Your gaming mullet controller has arrived.

That’s right, it’s a shoe with Nintendo inside. This shoe has a fully-functional original Nintendo Entertainment System built in, so you can enjoy all of the classics right from your foot. It’s got sole. Insert a sports game and you have a case of athletes foot.

We covered this literally a year ago, but since all the other gadget blogs wanna act like it’s new, we figured we’d share it again. Just for Kicks. Get it? Kicks?

It may look real…in a cheap plastic sort of way, but don’t let it’s looks fool you. This Nokia E75 clone is not from Nokia by a long shot. But hey, you do get a built-in NES emulator that lets you play all your favorite old school games on-the-go.

Some other features include a 2.6-inch LCD display, 1.3-megapixel camera, and a built-in FM tuner. Even a “magical voice” feature. Other than the NES feature, there’s very little to love with this knockoff.

Look at it. Just sitting there ominous like the monolith in 2001. Watching mankind since the dawn of man. Waiting. Waiting for a mouse manufacturer to run with this design.

Because right now, this beautiful work of art is just a foam mock-up. The first company to build this will have my money. I don’t care how much. I’ll just hand you my wallet. I don’t even mind that the D-pad is on the side.

Chinavasion’s latest offering is a retro portable gaming system: The Multi Platform Portable Gaming Entertainment Station. It sure doen’t look like the standard DS. This handheld will handle ROMs from NES, SNES, Sega Genesis, Game Boy Advance, Neo-Geo and selected Capcom arcade systems thanks to its 4GB internal memory.

The device sports a miniSD memory card slot for expansion and a 2.8″ display at 320 x 240 resolution. Not that we are condoning ROMs, which are illegal if downloaded from the Net. ROMs are bad. Just say no.
