well just about how much dose this cost to make?
currently im still on step 0 all i have is a gamecube and controllers
well, then you need a battery I recomend this one, low cost, and powerfullbattery
you will need also a screen
the most of people at this comunity used PSONE screen, they told it have high picture quality and need low power (even it will need lower power after the led mod).
the psone screen I think is arround 40$ - 55$ (It may differ from some sites , or if the screen has been used)
you will also need some tools, and wires (I cannot tell you how much it will cost, cause I dont know the tools you cuarently have or the cuantity of wires you will need)
arround 70$ (battery + screen)
and then you may need more money for some minor tools, wires, hot glue.....etc (maybe 30 $)
well, the fact is that it may take arround 100$ for everything, (bing optimist
you also may need to buy another gamecube, for extra parts, or replacements in case something goes wrong.
it also depends what kind of case you want to make, some casing methods will require some extra tools, and mats
btw, this differs a lot ^^
and relating the entire project, it also depends the money you want to spent on it, anyway, if this is your first project, I would try make it slowly and checking several times every steep.
thats why I cant tell you the final amount of money you will need ^^
make a portable is allways a surprise, it will take a few time and probably some minor troubles you will take some time to fix.
but after acomplish them, you will earn lot of knowledge and a awesome portable you can play having fun on it and you can also show your friends hehe.
If really want , go for it
