i want to solder a female end of a usb cord to the pin outs on a gamecube memory card. so i can put a usb sd card reader in it and use it as a gecko. is that even possible? it makes sense cause you can read a sd card from a usb, but the usb cable only has four pins and the sd has 9. 7 in use if i were going to just use a sd reader and make it the traditional diy way with out the usb. so any info would be really helpfull.
i did infact see that tutorial and would be making something like that, but instead of directly putting the sd reader to the cards pin outs, i wanted to solder a usb cable extension to the memorycards pins so pretty much i would have a usb slot to plug into, then i wanted to plug a usb sd card reader into that. does anyone know if that will work? in the tutorial mentioned above, it uses the same amount of pins, but if i were to put a usb cable in it, it would only involve 4 wires..... see i would using something like this http://www.coolgear.com/images/USBG-CM1211.jpg
and be plugging in one of these http://www.instructables.com/files/deriv/FTZ/IAGD/DJ3ES9J3XGH/FTZIAGDDJ3ES9J3XGH.MEDIUM.jpg with my sd card in it. think its possible? or anyone know how? if it is possible, all i need to know is what pins to hook up too.
That's exactly what I was talking about, and if you want to try it go for it. I haven't seen any tutorials on it here, so you may be the first to try it on wiinewz. No reason not to try it if you want it, worst that happens is you spend 10 dollars and it goes nowhere.
It's not simply an USB/SD adapter or anything like that.
The USB gecko is a serial interface.
The USB is connected to an F232 (or something along those lines).
It converts Serial (RS232) and USB communications, allowing serial applications to operate over USB.
From there, it's just a good deal of complicated stuff.
Not really horribly complex as far as electronics go, but from your "Wire a usb cable to a memory card" thought... It's a jump...
You're better off buying a Gecko.
Chances are (though I have yet to see internals of the Gecko, which is why I can't get into much detail) the Gecko's communication is based around an MCU communicating with the computer via USB through the F232 (Or similar).
That being the case, you'd have to basically just make from scratch your own new product that's simply a clone of the Gecko, seeing as how I doubt anyone's gonna dump the Gecko hex (assuming it's an mcu in there).
I'm not saying "This is stupid, screw this you noobs".
I'm just saying it's not as simple as you guys have described.
Heck, I'd be all for an "OpenGecko" kind of a thing.
Also, does anyone have shots of the guts of the UsbGecko?
So...
Looks like the USB is connected straight to an FT232 (or some other similar component).
But frome there...
The component on the left I'd assume is, in fact, an MCU of some sort, I can't identify it, not bothering to research it er' nuthin.
you need to remember that the sd card slot is directly connected inside the mem card and what you are proposing with the reader has all the internals of the reader between the memcard and the sd card
im not saying that it wont work somehow because ive never tried it but i dont think theoreticaly that it will
cause the sd card reader needs drivers to run and on the wii/gamecube you wont have these drivers
the only thing i can suggest is if you are going to try it you need to figure out what pins on the usb match to the memcard
trial and error is how all this hommebrew started in the first place
id be interested in your results
if you are successful you could open a door to so many more possibilities
with usb peripherials
Good luck
