Today, I'm going to show you the current state
of my raspberry pi wearable computer, that
I am currently wearing right now.
I'm also going to describe a little bit about
what I'd like to do in the future.
Here's the computer itself.
Around it you will notice the power cable
that can be easily disconnected and you unplug
it from both boxes, and I'm going to disassemble
it so you can see how it is made.
I held the battery pack to the RaspberryPi
with rubberbands, so it does not have to go
into your pocket like the last version.
I also found that the velcro straps that I
was using in the last version were not as
good for putting things together and they
can also be a pretty big problem when you
are wearing it with clothing.
I managed to stuff a five-volt charge controller
and four double A battery holders in an Altoids
tin along with attaching a power switch to
the side.
The RaspberryPi itself lacks a power switch
so that's a good addition to have as well.
That's the battery pack, and now we're going
to take a look at the Pi itself.
The raspberrypi is in a case I printed from
a design I found on thingiverse.
It has a belt clip so you can attach it to
your waist for easy carrying around.
There's my wifi adapter and keyboard connector.
I put some heatsinks on it just to help things
stay cool, although it is meant to be worn
on your waist, which allows it to vent easily.
Now I'm going to show you a look at what it's
like behind the screens.
So, first we have to hit the power switch
on the Pi, and you'll be able to see the light
come on through the case.
I also have to turn on the video glasses because
they're powered by a separate power pack.
The raspberrypi is going to boot up and, it's
going to be a little hard to show you this
on camera, but it is currently booting.
And you can see the Raspberry in the top-left
corner of the screen, as well as the log outputs.
The UI is loaded and you can see the mouse
is on the screen, we're at our desktop, and
I'm going to open up the web browser, Midori,
so you can see what it's like to use the computer
through the screens.
There it goes, and we're going to be on the
RaspberryPi quick start guide page.
It might not look so great through the camera,
but again you can read the text while wearing
the glasses.
If need be, you can increase font size, you
can change the font colours so that they are
easier to read over the background, especially
on the taskbar, and I did that on the desktop
and made the font an off-white colour so you
can see it against the black background.
And that's my wearable computer.
So there are definitely a lot of improvements
that can be made.
I want to consolidate the actual pi box and
the video glasses box into one system.
I want to make it more compact, and, eventually,
a newer design will have one wire going out
to the glasses.
I'm going to tinker a little with these glasses
to see if maybe we can make them a little
smaller.
Some people on Instructables also suggested
I use cameras on the front to make it a more
augmented reality experience.
As you noticed when I showed you the glasses
you cannot currently see behind them.
You can see around the lens but you can't
see behind them, and that's a little problem
if you intend to walk with these.
I advise you don't do that because you might
find yourself walking into walls.
I'm going to switch to a LiIon battery pack.
I've been investigating that a little and
it seems like that will make a slimmer design.
It will be easier to charge, and might even
have a higher capacity than what I have now.
I'm going to design a new enclosure.
The current design is something I got off
of Thingiverse and I've linked to that in
my Instructable, but I'm going to modify that
to have room for the batteries and room forr
this as well.
I'm going to try and see if I can power this
with a slim LiIon battery pack as well.
That would greatly enhance the carryaroundability....
that's not a word.
The carryaroundedness.... that's also not
a word....
I'm going to carry it around.
So, thanks for watching and I'll see you guys
next time.
