Flawed?? What is flawed? If I calculated something wrong please tell me so I can change it.... i'm not the best in these kind of things please tell me what isn't correct :D

Where are you finding the regulators. I've only found regulators that go up to 3 amps.

I've really got to slow down on the posts, 500 in 3 months of membership, seriously, 5.5 posts a day.

I buy my regulators at a radioshack like shop here in holland. But like I said i don't think it's of any use to make a custom regulator sinds it won't be as effecient as the original one.

meh, 5.5 posts a day is nothing, I'm pretty sure bicostp averages somewhere around there. That is about average for an active person on the forums.

zenloc wrote:I just measured the total draw of the cube and came to the folowing conclusion.
1,9v draws 6000mA and at start up and in game sometimes goes up to 6600mA so nowhere near the 2500mA that was measured before!!
3,3v draws 800mA
5v + audio draws 350mA
This was measured from the original regulator with the 12v line briged to 5v line on gamecube mobo
12v draw complete regulator goes up to 1700mA
The reason the regulator got so hot was that it was exceeding the 5A draw. Skyone could you find a 7A swichting regulator?
So in watts this makes much more sense:
1,9v x 6,6A = 12,54 watts
3,3v x 0,8A = 2,64 watts
5v x 0,35A = 1,75 watts
in total = 17,03 watts if you would power it with a custom regulator
and 12v x 1,7A = 20,4 watts if you would power it with original regulator
I knew it!!! I knew ER's readings had to be off, there was no way that the stock powerboard was 50% efficient (his readings add up to only 9W or so).

I'm sure he'll be open to correction :P When he re-appears.

Hey, for the record, I just compared your calculations to my battery life and they don't seem correct. Mind you, I can run a LED modded psone screen, a gamecube w/original powerboard, mario's low battery life LED, and the original gamecube fan for 2 hours and 10 minutes, with a fully charged 11.1v 6400mah li-ion battery.

I think they are pretty close. Once again, nice job finding out the frikken 1.9v line take 7 FRIGGEN AMPS! :lol:

Oh, and a good 11.1v battery won't drop its voltage past 10v before dying. I experimented recently and I came to the wrong conclusion before mario worked out the low battery life LED thing for me(it still fit its application, sheer luck). The pcb cuts off the voltage promptly and properly, as anything else would cause damage to the unit.

Think the way a GBA SP works, the backlight doesn't fade out or the screen either, it shows the red light, and eventually cuts off. The battery pack I was/am using was designed to do the same thing. Huzzah! No damage to components, and longer life(as in the time the battery will last before I have to replace it).

Thanks SS for clearing up the 11,1v line. I'm not too sure about the calculations but they do sound realistic. I'm going to get a 14,8v battery then I can see how long it wil last using the original regulator. I'm just wondering if you get 2 hours and 10 min with a 6400mah 11,1v battery that's not that long. Considering the calculations I made then there's something wrong with them.

11,1v takes 1950mah an hour
led modded screen takes about 350mah an hour
battery led and fan are low so let's leave that out

so in total you would use 2300mah an hour so that means according to my calculations you would get a bit more than 2:45.

But yours is draining about 2950mah - 350 = 2600mah just for the cube. So let's say out of personal experience of SS the gamecube draw's 2,6A on 11,1v. Have you tested your psone screen amp draw it might be higher than 350mah??

I just tested powering a gamecube with a 14,8v 4000mah battery and got the following result. A whopping 2 hours and 50 minutes. Remember that this is only the gamecube so NOT with a psone screen added. So checking my calculations I said the gamecube would draw 1400mah from a 14,8v source which seems to be about correct.

With this we have the information we need:

with a 14,8v battery it's 1400mah (tested)
with a 11,1v battery it's 2600mah (tested by SS)
with a 7,4v battery it's 3000mah (untested) haven't built a fully working custom regulator and problably won't

Remember this is ONLY the gamecube draw with nothing else. I can't understand why I can get 2:50 and and SS can only get 2:10 as my calculation for the 14,8v was correct than it would also be for the 11,1v. It would mean the efficiency of the regulator is better at a higher voltage. So i'm guessing that the regulator can work with a lower voltage than 12v but will not be as efficient as with 12v or above. Continues on babbeling with myself :lol: Correct me if i'm wrong though.

Replacement 1.9v step-down:

PTR08100W

Come to think of it, your measurements make sense. 11.4W from the 1.9v line alone sounds just fine. 3.8W from Electric Rain's measuring seemed to be a bit hopeful. :lol:

that step down regulator looks perfect 10A :shock: that thing will probably cost a bunch. If anybody can get me a couple of samples and send them to holland. PM me :roll: In exchange I will make you a fully working regulator :wink: ofcourse only if I get it working :?

They're about 12 USD off Digikey, dunno if they ship to Holland though...

just orderd a couple seems they do ship to holland :D But for now I'll be using a 14,8 battery anyway so no rush.

Good luck! Ask if you need any help wiring it.
