Yeah... there should be no clicking. That is a bad sound :(

D'aww - page break.

Well, the pth should get here tomorrow - I have another issue. I bought a little, thin 40mm fan to help cool the system, it draws roughly 80 mA at 7.4v, but it runs really slowly at 7.4v, and the air output is negligable. I was wondering if there are any free samples I could request from TI that are capable of bumping up 7.4v to 12v? I plan on buying another fan, so the max current draw will be around 160, assuming that power drain stays consistant at higher voltages, which it probably won't - if anything, I think it'll go down. Thanks! Alternatively, if people could suggest a better fan that runs nicely at 7.4v, has a decent CFM, and is pretty quiet (around 25-30 dB is fine), that would be great.

get the ptn04050c . it cant take 7v in so you need to run it off the n64s onboard 5v regulator it will supply up to 15v you need to check the data sheet for what resistor you need but you will also need 2 100uf caps. i know 2.2kohm resistor gives you 10.5 v

:/

I'd rather avoid using the N64's 7805 regulator, 'cause it's rather inefficient. I'll keep looking around, maybe I could just buy fans that run at lower voltages.

Hey, I wired everything up, it's finally looking good - I plugged it into the TV (Screen isn't here yet) and turned it on... a white line flashed across the screen, then nothing. I think I might have screwed up the cartridge relocation, and I was wondering if anybody had an eagle file or picture of the PCB for a cartridge so I can etc a fake on to test the connections - does anybody know where I could get something like that? I just need the exact spacing/sizes of the pins so I can make a pseudo-cartridge solely for testing connections.

I'll get them soon, but does anybody have a link?

Alright, pictures:

When measuring a few of the connections with a multimeter, several of them had no resistance at all between them - only 1 pair was right next to eachother, though. Are any of the pins supposed to have a complete connection?

I'm thinking I'm going to use lucidperspective's method with IDE cable and a header - question, would this IDE cable work? (Can I move the connector so I'm not using 18" of cable, but just 6 instead?)

And then would this header work?

OK, new problem (That's all this portable seems to be...) is the controller.

I heard something about not being able to use an original n64 controller unless you wanted to be stuck with the original joystick because it isn't like normal joysticks. I bought a ripoff brand controller, a clone (more or less) of the original controller. The joystick looks like an official n64 one - I'm assuming this means it's unusable?

If somebody could point me toward the least expensive controller that will work (I.E., that I CAN replace the joystick on) on eBay or Amazon or something, that would be great.

theres a broken n64 controller lot on ebay i think its 15 controllers for 25$ its a deal because your salvaging the controller anyway and usually they are easy to fix. just search

nintendo 64 broken controllers.

I can't even understand that post. I'll get pictures of the mobo.

Alright, I now have pictures (As high res as before, but with an annoying flash glare this time) I'd like an opinion - do you think it'll work or not? I'd rather not cut up my ps1 controller yet, as I'm having fun with an emulator and the controller playing through some n64 games as I build my n64.
