Hey Rakon, I think documenting this epic journey of yours would be pretty cool. I guess there's a few things you should consider:
-A decent video camera. You don't have to go all out but when I say "decent" I'd suggest something that's capable of recording up to 1080p resolution (full HD). You can get one of those small handy cams, or you can get those sorta... mini DSLR cameras, capable of taking not only good photos, but good video too. Hell, you could even use your phone too, depending on what kinda phone you have. Because you're on the go, the quality doesn't have to be super awesome. That "shaky cam" look is a bit more authentic, especially for a traveller.
-SD cards, you'll need a few of 'em. I'd recommend big ones too, like 32 GB or so. They can be a bit pricey but if you shop around online you might be able to score a good price. I'd recommend "Class 10" cards as well, anything lower than that and video won't record properly, especially on DLSR (or those mini ones) cameras that are capable of doing video.
-I'd recommend having two batteries for your camera. Buying a second battery can be a pain in the arse sometimes, so if you can't find a second battery for a decent price, don't worry too much about it.
-You'd need a laptop or something to be able to download your footage too. Also you'd need software to be able to edit your video. You could always roll with Windows Movie Maker, or the Adobe CS2 suite as it's currently free online from Adobe themselves (although you have to make an Adobe account to get 'em). If you want to, I could essentially give you Adobe CS2 via Drop Box? Just let me know and I'll see what I can do.
-I'd suggest getting a hold of an external HDD, a big one (like 1 or 2 TB or something). I'd also recommend an external HDD that doesn't require a power source, so it's just more convenient for you to back stuff up.
-Finally, I'd suggest either documenting your travels in the form of a YouTube channel or maybe a blog. You can have it private or public if you like, just means you gotta set it up that way. I'd suggest trying to make your documents/recordings at least once a week, or once every two weeks. You could also use other social media to help document your travels, e.g. a Facebook page, a Twitter account etc. I'd suggest only running with two forms of social media, any more may tend to water down your efforts so to speak.
-You could also have a note book with you, as in... traditional pen and paper. Write down anything you think might be interesting to talk about, something you saw that day, ideas you come up with etc, just to help you remember stuff.
If there's anything else I can do to help you, please let me know.
