Worklog Portable PS2

Two of these http://www.batteryspace.com/polymer...18-5wh-10-0a-rate-----un38-3-passed-ndgr.aspx

Seems they are out of stock currently, I had grabbed them months ago for the original design and they fit into the new design perfectly after switching the orientation in the case.

Sweet, how much current does the PS2 pull?

"Conclusions:
Stock PS2 Power Consumption: ~9.57 Watts (In Game)
Custom regulator PS2 Power Consumption: ~8.42 Watts (In Game)
Stock PS2 uses ~1.15 Watts more than modified motherboard"

A little bit more current than the Wii in perspective but 9.57/8.42 watts is not bad for a portable console.

Oh, nice. So you're looking at ≈4 hours of battery life? That's pretty great for two lipo cells!

With the entire portable, in my real-life tests with a 7.4v 5A pack, it is generally closer 3-3.5 hours of gameplay which is still pretty good.

Gman is a beast! Looking good!

I put a thick clear coat on the case, going to wait atleast a week for it to cure before assembling it. In the mean time, I have put together the battery pack and trimmed the board. I kept the stock regulators on the trim. I haven't tested it yet but I'm pretty sure it should work.

is that 3d printing?

The case was modeled in solidworks, 3d printed, then sanded extensively, and finally painted.

How long did the case take you to design in SolidWorks?

The physical actions of modeling the case does not take very long, maybe a few hours. But thinking about placement, fine tuning, many iterations.. can take weeks to figure out.

On the scale of 1 to 10 how hard was it?

So much this. Modeling "a case" is easy. Modeling the perfect case for all your parts is an art, and takes lots of tweaking.

Im not Gman, but that's not really a fair question, because that depends on your knowledge of CAD. I would advise looking into CAD 3d design. If you put in some time, and you can really get a lot out of it.

Looks like a fantastic print! I've seen your VGA (and insane trims) but no wondered if you were selling your VGA boards/pinouts? Composite is hurting my soul (and all the pretty games)

Listen up people! The PS2 outputs native RGB and their are vias for H/V sync from the CPU. You can perform a very simple modification and get VGA from your PS2 very easily. I think the digital RGB is a little more adaptive, there are more features to implement and output options like HDMI as well but a custom board is not required if you just want to upgrade your video quality from composite. The only downside from this new native VGA is that it is a 15kHz sync signal which is not accepted by the majority of monitors, you will need to do testing/research on your own to see which option suites you best. More information regarding in depth details and installation will be coming soon.

If there are both H and V signals shouldn't the output be 31khz? Seeing as both signals are being used for syncronization a full Progressive signal should be produced, right? 15khz is ussually Interlaced, not?

If Interlaced only is possible natively, your DAC board would be preffered.

It seems I'm wrong?

Thanks @Gman, I'll look for the vias on the 79003 since they seem to move quite a lot between revisions and see how I get on.

H and V are horizontal and vertical sync signal. 15 kHz or 30 kHz is the frequency of the H sync signal, so basically how many lines are drawn per second. With a [SOMETHING]x480 resolution 15kHz means having interlaced video, while 30kHz means having progressive video.
