can use without heatsinks?

the nintendo 64 does not HAVE an RF adapter. i hope you mean just the plug for the a/v cable, because if you hacked off anything else your nintendos probably broken.

how did you take it out. did you desolder it? if so, just put it back on. theres no reason to take it off until your almost done your portable. it comes in handy when you want to do things like this. if its destroyed, then find a pinout diagram for the connector, and loacte the video and ground pins. find old coaxial RCA type cable (the ones that you are used to useing. you know. red, white, yellow), so yeah cut it in half, and strip the wires on one half so that you can solder them to the board. the one thats around the outside is ground, and the wire running through the core of the wire is where the vodeo signal goes. then you can plug it into your tv like normal.

if you have a proper soldering iron, that capacitor would be reasonably easy to get back on. if youre unsure of your skills, practise on something thats broken.

oh and "cap" means capacitor... :

well i just took a pair of pliers and ripped it off cas my solder wasn't working and I was getting pissed off. Then I threw it in the trash and the trash people have come and gone so o well... I do know where the video pin is because on the back of the mobo there are little letters next to each one. Three distinct ones are : R - i think right audio; L prob left audio, and; V - again probably video. I f nintendo was smart about putting the right markings on their motherboards then that is wut they should be, but we neer know with the big n

but thanx for helping me with the rca cable thing...

Also can I recharge the batteries while still being inside of the case. I would like to still use the n64 original plugin to power the system when the batteries are'nt in the system or are dead/ charge the batteries. So if were to get rechargable AA batteries, can I use the plug in to charge them. If NOT then could I take one of those wall chargers, shove it into the portable (might make it kinda heavy) and connect the n64 plug in to the battery charger with the batteries permenately in there, while running the system off them? any ideas?
don't know why u guys don't like reposts but sry

ok, first lets take care of your double posts: theres a button on each of your posts that says "edit". click that to add more information/questions to your last post, instead of making a new one

the battery thing is doable, you have a few choices

1) measure the capacity of your batteries, and charge them exactly long enough through a resistor, but otherwise straight off of the n64 power adapter. this is the easiest way, and also the easiest way to destroy your batteries. they dont like to be overcharged, you wouldnt want to be leaving this sort of setup overnight, your batteries might explode. who knows.

2) *somewhere* on this forum there is instructions on how to build a so called "trickle" charger. you can leave the battereies on this kind of charger indefinately. this probably isnt for beginners

3) i am currently working on a circuit that will be able to shut off the batteries when they are fully charged or fully drained. it probably wont be done until well into the new year, and im hopign to be able to sell it for $20 + shipping.

4) take apart a battery charger and add the nessecary components between your batteries and the n64 power supply (you wont need to keep the big transformer, since the 64's PSU already has that). this probably isnt for beginners.

5) design your portable with a RC car nimh battery pack, and a battery door. take it out of the system when its dead, and put it on the charger that you can buy for it. this is probably the easiest way out of all of them.

The reason you can't get video on the TV is because you need to connect video ground, as well as composite. Use the pinout on PoD.

hey thanx for he link. found the a/v section so I'll be using that. Also found the battery section and they were talking about parralel and series types of putting the batteries together. I was wondering, could I do both types in one?

when you open up the link, maximize the window or else it will look weird...sry

you can do both 'types' at once, but the way you drew it is kinda weird. just do it like this:

Code: Select all

sounds good but would this still suply 3.6 V like mine did? (i know 64 is 3.3 but its the closest i can get wit rechargeable AA batteries)

edit:

oo wait never mind. just realized that they're the same design, urs just looks a little different. nvm...tee hee

They're not quite the same, but they have the same effect. Your's was 3 parallels(of 2) in series, while Tim's was 2 series(of 3) in parallel.

timmeh87 · Post by **timmeh87** » Tue Dec 20, 2005 6:21 pm

mine uses less wire

also, you cant just hook batteries directly to the 3.3v line. well, you can, and you might get away with it, but its not adviseable. you should have some sort of regulation to prevent bad thing from happening. (without regulation, you also wouldnt be able to charge them while playing, sine you have to give them like 4-5V to charge, which would definitely fry the 64.)

Well getting a dc dc converter.

edit:

I've been contemplating for a while on whether to actually use li-ion batteries or rechargable aa batteries. would like to know the different setups i could use. like for example. the aa batteries would be 1.3v each. and the li-ion might be like a 3.6 v (now heres a part where i'm confused, would the batteries need to be @ the 3.3v line or the 12 v line. plus i don't know where the 12v line comes from, so could u also clarify on that too. lol i know i know but please try and help a noob

) 3600 mAh . would like to know about any converters needed, adaptors, regulators that would be needed, if i were to keep my n64 brick plugin as the external power source and to charge the batteries while still inside. thanx guys (and girls if there are n e on this forum)

oo and btw think i'm gunna call it the m64... hmm sounds goood
