Instructables
Picture of RaspberryPi Powered Wearable Computer

I have been interested in wearable computing for a while.  Until the RaspberryPi was released, there was no affordable and compact option for the computer part of a wearable computer.  My original setup used a laptop in a backpack, but that is a little too big to be practical.  I have seen a lot of arduino based wearable electronics, but they are not exactly what I have been looking for - a full power desktop computer that you can carry around at your side and use while walking, standing, sitting, or doing anything else. 

As a linux guy for many years, the RaspberryPi is the perfect solution to my problem, and I'm already comfortable with the OS.  Before you begin, make sure you read through my instructions.  I have updated several sections through the past few months. 

Just so you guys know, this is my first instructable after being a lurker here for almost seven years.  I'm excited.  So, let's begin! 

Update March 2013: I am now using a new (3D printed!) case.  Significant updates to the battery pack made as well.  The new case prevents the Pi from being totally enclosed, and marginally decreases the form factor. 

Update September 2013: Added a new video demonstration.  Check it out!

You might instead add the raspberry pi camera to the outside so you can walk around and take pictures of the way you are facing...

What kind of image quality do you get from this? Can you read this comment on it?

he said his glasses are 852x480px each

could you provide amazon or ebay links for these?
I live in Israel, and it's pretty hard for me to find electrical supplies where I live that arent grossly overpriced

Thanks!

Pretty cool. I think the word you're looking for is "portability".

I'm not really sure how your glasses work, but, depending on the tech, the LCDs may have semi-reflective back panels (to even out the back light distribution?) or just a sheet of something opaque. If you can get that off, you should be able to see through the lcds (they should be mostly transparent). If you can turn the backlight off and have software that sets the pixels for white (presumably the max transparency of the lcd) you might be able to have better visibility through them.

It would probably be good to have UV protection on the outside edge in such a design, as the amount of light that travels through the lcd might be small enough to cause your eyes to dilate (to let in more light) and thus expose you to more UV than usual (if the glasses don't block UV).

Translucent might be more truthful, but it would probably be better than not being able to see through the.

I am thinking about doing this for about a hundred bucks because I already have everything for the Pi I just need a keyboard/mouse combo that is bluetooth...

I think going li-poly here would be a reasonable option. Lighter, smaller, and quite a bit more power. The tricky part is dealing with charging and such but even then, there are several pre-made packs that would fit the bill if you don't want to get into rolling your own.

Yeah, that's a really, really good idea. I've recently improved the battery pack a little bit, but I do think you're right on going to li-poly batteries. The biggest interest I would have is not only more power and a smaller pack like you mentioned, but also cost. The battery pack I used in the project cost a total of $70. When you think about that being for only four AA batteries with a charge controller.... that's a decent 15-20% of the project cost. Any ideas where I could find a pre-made compact pack?

How about li-ion batteries? I should think they would be easier to charge. And since they're used in cellular phones, slim li-ion batteries in the size of a Raspberrypi might be easy to come by.

I recreated your instructable except for the power pack. I bought a dual output rechargable 5v 2.1 mAh and 5v 1.5 mAh but its not enough to power the edimax wifi, candybar keyboard or even a wireless mouse. I even tried hooking it up with a battery powered hub without success. How many amps. is your power pack putting out? What operating system are you using? Wheezy has worked the best for me so far, as far as loading the bluetooth drivers for the candyboard and edimax; I couldn't get those same drivers loaded for XBMC. Advice will be appreciated!

Nice project! Those mini wireless keyboards, you can buy them here: http://voltatek.com/en/home/20-mini-wireless-keybo...

They sell them cheap and ships from Canada!

They also have mini wireless adapters for Raspberry Pi:

For video, use omxplayer, as it can decode h264 via the RPi video chip, that has no issues with full hd. The CPU can't really handle sd video, but the gpu is all another thing. :D
