Atmega8 can definately do it.

I believe there is an open source project on it (from what i saw, it supports up to 4 controllers at once, including a mix match of snes controllers and also support the 4 port nes adapter on ports 1 and 2 of the chip)

couple notes

its a 328 :)

and it doesnt show up as a HID keyboard, it shows up as a HID Joystick

oops! instructables detected! no clicky.

Let me squash the “instructables BOO” crap quickly too

look at it from my side, since I joined they provide me a stable place to post my projects, and I do, for that I also get a large audience that is highly active, I have also gotten T-shirts stickers and other swag along with xmas cards, Halloween cards (more stickers) and have won gift certificates to think geek and enough gorilla glue to last a few years

I am going to post it anyway, it might as well be there since they treat me well (for a website) and have the chance to win a pocket knife at the same time

yes Instructables BOO indeed :p

I’d like to see a bluetooth implementation of an [S]NES controller.

you hook them up backwards, and they have a very low breakdown point (like 1.2 volts) and thus start to leak current backwards through the diodes to ground, your lower voltages are whats left over

I too am getting pretty sick of the instructables bashing. What exactly do people have against it?

@tim:

How is it stolen? It’s a similar concept with completely different implementations. I see that one user did a similar thing and posted an image of it, but there’s no documentation of it.

Sorry that everything can’t be a one-of-a-kind masterpiece.

@Memento

I made an NES bluetooth, but it might not be the kind you are thinking of. It’s a bluetooth headset.

I have an idea for using this to monitor the input given from a nes controller. as a part of this, I’d like to be able to hide something small, a few small coins in height.
Would it be possible to tweak this project to allow that? I’m not sure of the height and clearance for free room with it.

No need to trash the controller. Since it is hard to get hold of NES connectors what I do is cut the end off and splice a DB9 into the cable. It then still works on a real NES and can also be used via USB.

i have several that i made just using a usb keyboard. it seems to be a way simpler approach.

I did this, unfortunatly i selected the easy pins to solder and that resulted in one pin not being supported by the software. And i used a Azerty chip for a Querty based software.

That Querty Azerty shit needs to dissapear.
