Pretty much all digital cameras/webcams can see IR light, just point a TV remote at it, press a button and you'll see it flashing on the screen. You make an IR filter from (if I remember rightly) an exposed or developed piece of film (can't remember which I'm afraid) so you can filter out the visible light and just have the IR (pointless, it's better to use the same camera for normal vision and night vision, although you could possibly have a filter on a rail so it slides over the lens and you can have cool night vision effects instantly... I don't think it's worth it though.
Bear in mind if you're using IR spots, your suit's lights will be invisible to people, but CCTV/police helicopters would see you lit up like a beacon. Just in case you were planning on going Tom Clancy =P
You can buy a USB GPS Dongle which will work on linux systems, not sure if they're any good, but it may be worth looking into. I think I saw one in the UK for about 20GBP
As for the motion sensor, I don't think it'd be a feasible option. When you move in the suit, any objects you pass will show up. You'd need some way for the system to differentiate between a hostile and a lamp post.
Try looking into Linux From Scratch. I'd suggest starting up a community project (Google wave is good for this) where people can contribute to a LFS system
@Anubis4451: We're a community! projects like that can be workload spread over the Internet and everyone can contribute, greatly reducing time required to produce a project. Plus a simple stripped out Linux system would work in the interim
@Kevlar: that said, you'd be best of beginning with xubuntu, which has a much smaller memory footprint. Also, if you can get an efficient cache for the camera it would work, but you're best looking at other things too, such as using an interface other than USB. If you can get hold of a FireWire camera it may help a lot, the FireWire interface is much faster than USB USB vs FireWire
The main problem with using Linux is drivers. You may find it difficult to get the parts you need working with Linux, so get forum dredging before you buy any kit. Measure twice and all that
Mmmmm...you'll have to get back to me with some more info on the IR filter, that sounds like a good idea. IR LED's aren't to expensive (in perspective) so i'll get quite a few of them. And i DO think it would be worth while pursuing that idea as well, if i were able to couple the visor with IR filtering, then i'd easily be able to just "flick a switch" and have night vision, also, less complication = greater efficieny = less breakdowns. I am yet to try google wave, but when i do, (and when i get the parts for the pc) i'll be sure to set up a project forum.
I don't know if i'd be able to get a hold of any FireWire systems, they are pretty expensive.
And if all else fails with the pc system, then i guess i'll just add a bunch of analogue electronics and microchips to do what i want.
Cheers!
