I'll post the schematic tomorrow, gotta get some amount of sleep tonight. Happy New Year!
Do you think you could post that sometime soon? I'm really interested in this.

Haha, sorry about this. I've been pretty busy over the course of the past days, I should have it soon.

So, do you think you could post them soon? It's been more than a week.

Hahaha! I forgot about it again. I've been really busy, sorry... until I'm able to find the drawing, what exactly are you having trouble with?

I'm really new to this stuff. I'm not attempting to do a project anytime soon, so don't feel rushed or anything. I'm just trying to find out as much as I can and deciding if a Gamecube portable is actually feasible.

The schematic is quite simple, and is actually in the MAX632 datasheet, the 7805 datasheet, and whatever else I used datasheet (I'll look later

), so I'm not sure what you're looking for really.

Ok, I just want to know one thing right now. Did you split up the voltage for the different rails and feed them directly to the motherboard, or did you put the 12v form the step up through the power regulator board?

All different direct rails (one for 1.9, 3.3, 5, and 12). It'd be extremely hard to find a 12v step up that handled all 2.5A.

I know that

. Thank you.

Sorry to bring up a dead topic (my own, infact), but Skyone, How did you get 1.9v and 3.3v in your power supply. Thanks again.

Post by **Skyone** » Thu Jul 03, 2008 1:30 pm

Code: Select all

Voltage     Part Number

1.9         LMS1585
3.3         LM1086
5.0         LM7805
12.0        MAX632

Schematic soon, this time for real.

1.9v - LM1585A Schematic

3.3v - LM1086 Schematic

5v - LM7805 Schematic

More to come.

Great, I need it too please!!

Please make it pictorial, like for the TI cards, so it is easy to follow!

Like ^that^, no?

Thank you, Skyone!

Edit
7805 Schematic (the one you least need)

More to come.

Yes, exactly like that, thanks! Nice and easy to follow!!

This is for the 5v line I take it, although I presume as the 5v is only for the CD motor as it starts up (or so I read) and only 350mA at that - could you use the 5v off the PSone screen (7805) for this? As the 12v is only 5 mA I presume a small 12v battery (like an AAA sized one) would last for days, or is a step-up better? The 3.3v I presume could be off a standard TI card (only 800mA so no issue) as per other projects; the one I would love you please to post is how to get 1.9v at 2100mA off a 7.4v battery.

I look forward to further pics!!

I realize this thread is a bit old but just getting back and rdy for making my gcp I have some money now from 2 jobs and Am finally gonna get my batteries 3 7.2 volt 2400 mah lithium ion batteries I plan on a parallel circuit.
I'm guessing I should just split the line and use various transformers or bleed resistors to get the 4 needed voltages.
