Step 2: RaspberryPi Configuration

So you have a RaspberryPi.  I'm not going to cover software installation and basic setup, because there are already some great tutorials out there.  Here are some helpful links for that step:


I recommend Raspbian, simply because I'm a Debian fan, and Raspbian is Debian, but optimized for the Pi.  If you already have a preferred distribution, great.  Use that. 

One thing that I do not like about the Pi is the lack of a heatsink over the CPU.  I don't care what anyone says about passive cooling, something about a CPU without a heatsink on it really, REALLY bugs me.  So go ahead and slap a tiny heatsink on your Pi's CPU.  I used a RAM heatsink from a pack of a bunch of them that I got at Microcenter.  This is ironic, since the Pi's RAM is on top of the CPU.  Anyway.... some folks are putting heatsinks on other chips, which isn't a bad idea.  I just happen to be bothered by the exposed CPU.  Plus, the heatsink does get hot during operation.  So it's definitely doing something. 

I then connected the WiFi dongle and my keyboard's wireless dongle to the Pi, and put it in the cell phone case.  I rested the Pi on a part of an anti-static bag, just to avoid shorting anything out. 

NEW 11 March 2013: I'm now using a 3D printed case for it.  The cell phone case offers the same features, but this printed case is a part of my transition to a slimmer and even more portable version I'm cooking up for the future.  This case is simply thing 33694 from Thingiverse. with a belt clip, thing 39983, hot-glued to the bottom. 

I have also swapped out the blue aluminum heatsink for a copper one, but that's not necessarily any better than the aluminum one since the Pi only produces negligible heat. 
<p><br>Its interesting<br><br>Thats useful...</p>
<p>Thats awesome</p>
<p>Its cold :)</p>
<p>What all can you use for a screen? Can I use something other than the specified video glasses?</p>
<p>if you dont mind not having a brand</p><p>These are around $50; http://m.ebay.com/itm/151712198885?nav=SEARCH</p>
<p>You can use anything that outputs composite or HDMI video. That is the beauty of the RaspberryPi. I chose to use video glasses for the purpose of making the entire setup wearable. </p>
<p>Amazing tutorial, very well done. I am currently making one of my own, albeit with only one display. My question is this; what kind of draw is there in amps by the setup? I am having a problem with the power pack I am using curently.</p>
<p>Thats awesome</p>
<p>Thats splendid...</p>
<br> <br>Its trendy :)
<p>I would say &quot;amazing&quot;, but i can't because my jaw broke when it hit the floor. This is one of the coolest things i've ever seen.</p>
<p>Note to those who have asked me a question to which I have not replied: Work gets the best of me sometimes. While I try to stick around to answer questions I do not always get the chance. </p>
<p>Hi,</p><p>I was wondering if instead of the listed Raspberry Pi Model B I could use the Model A+?</p>
<p>Sure, that's probably an even better choice now that it is available since it uses less power. Your only challenge will be using one USB port. USB can only output so much power so if you want a keyboard and network connection it might be a challenge. </p>
<p>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...</p>
<p>Appreciate the links that you gave and the pricing, thanks for that!</p>
<p>Thats astonishing...</p>
<p>Its helpful :)</p>
<p><br><br>Very good...!!</p>
<p>Its helpful :)</p>
What kind of image quality do you get from this? Can you read this comment on it?
<p>he said his glasses are 852x480px each</p>
<p>could you provide amazon or ebay links for these?<br>I live in Israel, and it's pretty hard for me to find electrical supplies where I live that arent grossly overpriced</p><p>Thanks!</p>
<p>Thats astonishing...<br></p>
<p>Thats marvelous</p>
<p>Thats remarkable...<br></p>
<p>Pretty cool. I think the word you're looking for is &quot;portability&quot;.</p><p>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.</p><p>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).</p>

<p>Translucent might be more truthful, but it would probably be better than not being able to see through the.</p>
<p>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...</p>
<p>Thats brilliant</p>
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.
