Making the pipboy/hitchhikers guide
Though there seems to be a lot of other people on this forum with the cash and possibly the motivation to complete this so I'll try and explain the idea for you.
If you've ever read 'The hitchhikers guide to the galaxy' by Douglas Adams or played the new or the old Fallout games you'll have noticed that the common denominator is that in both instances they have nifty little pocket computers with all kinds of information and gadgets.
Now I realize that it will be overkill for most people to have a mini Geiger-counter, a gas measuring device and a light sensor attached to it, not to mention to expensive.
But it seems odd to me that some of the software options available isn't already included in mini PC's, such as:
-Wiki-taxi which is an offline version of the entire Wikipedia.
-As many search-able dictionaries as is practical.
-A general library of PDF's that you find useful depending on where you are/are going to go, or maybe the PC you get your hands on has enough space to encompass a general library for the entire world like information about herbs, plants and animals in every region of the world
Instructables for certain kinds of gourmet dishes for an example could come in handy while traveling the world, anything goes really .
-Furthermore it could have stored maps of the entire world, of course not in "hair counting quality" but good enough to find your way if lost, then again some of these mini PC's have GPS built in but you will still need all the map packs for the different regions of the world.
-One could add how-to videos of different things that might come in handy if traveling in poor countries or simply backpacking, like braiding and general hand crafting items to have something to sell. Or guides for learning to play a certain instrument and so forth.
And so on, there's an endless supply of software one could put on a gadget like this, but that's just half the idea.
The other half would be constructing some kind of housing that would allow a person to strap the computer sideways on ones arm so that it's always easily available like a normal wristwatch and preferably protected against shock and moisture/water, furthermore it would be nice to have extra slots in the housing for such things as a small LED flashlight and any kinds of other tools that would be practical for the person in question that makes this thing.
This computer would of course need to have a rather big battery capacity as well, and if it has long lasting batteries then several more of the batteries can be incorporated into the housing allowing the user to switch between each of the extra batteries when the original one in the PC runs dry.
For off-the-grid travel I'd believe a sufficiently large fold-able solar panel would suffice to charge the device, maybe it could be incorporated into a jacket or simply stored as a liner in the jacket.
Now I don't know if this is all easily understandable so if anyone has any questions or maybe someone would even make this then please let me know as this idea is quite dear to me, do post any ideas or complaints as well, I welcome it all.
Oh, and in case someone might be bothered by the extra weight this would put on (say your left arm) then simply make another housing for general tools that you can have on the right arm/wrist and balance the weight out so that after a while you wont notice it as your muscles naturally adjusts to the weight, would basically make you stronger in the process.
