I am going to present my around the world equipment here. Thanks to my other hobbies which are cycling and hiking I already owned much of it.
PS: After one month of travelling I am sure I have taken too much with me, will get rid of it and give it to my brother, when he meets me. I think everybody does this and he is happy to have a lighter backpack. Currently its round about 15kg, I think I will leave behind 2-4kg.
Backpack: Deuter Aircontact (45l-10l)
Daypack: Jack Wulfskin Hamrock 16
And: Ziplock bags
"Pack It" compression bags (different sizes)
Other bags to put everthing in order or separate things
Stable boxes for technical stuff
Waterproof case for mobile phone
Technics:
Samsung Galaxy tab (instead of Computer)
HTC One S (mobile)
"EasyAcc" batterypacks
Different adapters
Beastvision actioncam
Canon Ixus
many flashdrives/cards
Sanyo USB Charger + Sanyo batteries (very small and great charger)
batteries and charger for lights
headlight, pocket lamp
