Picture of Necomimi Arduino Cat Ears
They are so dang cute. If you have ever seen the cool promo for the Necomimi Neurowear wearable set of cat ears that respond to brainwaves, you would want a set too. But it seems they may be vaporware since it hasn't materialized on the market yet, not that I would be able to afford them though. Necomimi or nekomimi is Japanese for "cat ears".

What do you do with them? You can wear it for Halloween or everyday, if desired. It may be for the anime otaku seriously into their cosplay. For the furries out there, I'm not asking so don't tell me.

Now what would the simplified caitlinsdad version be? Well, getting into advanced monitoring and feedback of brainwaves might be kinda expensive(they are dumping at the toy mega-store those Star Wars force trainers - control the floating ball with your mind- now $60 from $100 or maybe gut an i-dog but then I don't think the gears are powerful enough) and building some raw circutry is way more than I want to do. Pulley and invisible strings is so ghetto(Not that there's anything wrong with that...). A joystick that controls some motors on a headband? I know, how about servos controlled by an Arduino? And how about using an accelerometer to determine tilt/movement/position of the head to trigger ear movement. Tilt sensor switches might be too basic. GPS gets complicated and compass magnetomometer only points North.

This gives me a project to use with my recently acquired Arduino(no, it did not fall off a truck...I have a receipt). Besides, Caitlin says I have to make this or sew her a custom sling/messenger book bag.

This instructable may be more of an Arduino primer than about the cat ears. Note that this is a prototype project and I am throwing it out at this stage in the spirit of Open Source. I know it can be improved a lot by others and with more time to tweak it.

Okay, they look like bunneh ears, kinda like a cat.

With one of the ear coverings on...

and the star of the show...

After viewing this “Instructable” I have no doubt that America, i.e., Americans, will solve the problems that plague mankind the world over. To think that the prototype was built on top of a Campbell’s Soup Can. WOW! I am humbled and overwhelmed to think of a world living in peace with everyone sporting their Cat Ears. What a concept. I can just envision the world’s delegates at the UN sitting down, putting on their Cat Ears with translation ear phones incorporated into the head band. Caitlin and the Cat Ears are very cute. Thank you Caitlin's dad.

I have no doubt that the world, i.e. worldy peoples, are secure knowing that velcro has been invented to solve those problems that plague mankind wherever an ordinary fastener will not do. I can't wait for when velcro2 hits the market.
In my opinion velcro and duct tape is need to save the world, lol

Those ears are so neat, I have to make some!
This is fantastic! I've been very interested in the transhuman movement, as well as EEG technology such as Mindflex, and this is one thing that strikes me as a step in the right direction. So cool!

Thank you, Dr. Frankenstein.

From the video's description, they say the "necomimi" ears will be out near the end of this year. Plus in other related videos, we see them being tried out at some trade show. So I'd say they are real and coming soon!

As for your instructable...AWESOME! It's obviously much more bulky and louder than the "necomimi" on the YouTube video, but I think its awesome how you did this one. Definitely a great starting point.

I think it will only appear in the Nieman-Marcus or Hammacher Schlemmer catalogues. Get those elves cracking on the knockoffs.

There's gotta be some loose arduinos around the office...and steal lift appropriate some servos from Randy's bots to make yourself some nifty dinosaur ears.

more usagi than neko but still cool now all that needs to happen is to shrink every , make it thought active ,and put it on everybody in the world and then we would have achieved world peace cause nothing can be anger when they look this cute
