another power portable question o.O

well guys, I have a question. I buy another gc and hacked the mobo (rewired regulator board,removed ports,sondered qoob, modified heatsink, cut a little of the pcb,... etc)

I have a gc regulator board working fine, well not really the 12v output of the regulator board dont work. (I fried with an accidental short

)

Like gamevelver did, I wired the 12v (for sound) pin of the main mobo outside of the regulator board (it will be feed directly by the 12v oficial gc ac/dc converter, I tested safe cause the oficial gc ac/dc converter output also 12v, so it is safe. and it works fine with sound.

well, now is the trouble, when using batteries of more than 12v

my batteries are 14.8V (the label text)

But I tested it with a multimeter and i got arround 16,5v.

the other voltages output by the gc regulator board doesnt care, cause the regulator board will do his job fine, but the 12v pin (in this case will be arround 16v)

will be safe to input it for sound?

I know gamevelver is powering his gamecube sound directly with 14.8, but im not sure if 16v will be safe.

my tv also run at 12v (well the label ask it accept voltages 10-15v) so i think it will support it cause it would have a linear reglator built in or something)

but about the gc sound im not sure.

can you give me any advice/info mates?

[edit1] well, I was wondering something.

I have arround 4 gc ac-dc converters. and oe of them have the connector broken, so I was wondering if there is any kind of dc lineal regulator (something with 3 pins, one to +, one to ground and one with the output regulated)

if is posible I want to regulate the battery voltage also for the 12v, its NOT very proffesional let try luck to the half of my project

nobody can help me?

Sounds like you need a 12v voltage regulator going from your batteries to the system/tv? Oh, and batteries sometimes show a higher voltage when there isn't a load on them. Sorry, I've not touched a GC, so I'm not sure what else I could say.

thanks for the reply.

yes,should be nice if I got one of them.

Due I got late reply to this topic,I tested it before with 17 v screen and sound and works fine. (testing twilight princess arround 1 hour with batteries)

anyway I will feel better if I use a regulator betwen tv and sound and batteries.

can I get some 12v regulator from the original gc power suply adapter? it output 12v so I think I can use some stuff from inside for convert power from batteries to 12v ,I also can remove all "Alternal power from the power suply" but I opened it and dont know what is the thing I need from it.

I have a lot at home. and IÂ´m to lazy to buy a regulator online and wait 3 weeks to get the stuff.

So if I will be able to sacrifice some of my power gc power suply it will be nice
