michael_0u812's PS3 Laptop Worklog!

I always try to engage them in conversation about electronics, acting like a total dumbass, then start talking about stuff they don't understand.

They tend to shut up after that.

i had dude at radioshack attempt to convince me that i couldnt use a 7805 and should just buy a usb-wall adapter instead. retards. hence why i buy almost all of my electronics online. its really nice living like 15 miles from sparkfun.

so michael, got cooling worked out yet?

 

[michael_0u812]

I'm sticking with stock cooling. The PS3's cooler is only 30mm tall, which is pretty short. I don't have room for water cooling and I can't afford to build my own radiator. I might swap out the fan for a lower profile 140mm fan if I can find a good one. That could make the cooler almost 1cm (0.4") shorter. Other than that, I'm just planning out where to put some case fans. Here is a diagram of under the motherboard:



I'm not sure if I should make the case fans pull air in or push out, or both

 

[Basement_Modder]

Put some additional small fans in the "can't put fan here" area, blowing out.

 

[michael_0u812]

Alright I'll try to find some small small fans to put there.

 

[samjc3]

theres some nice little 12v fans in dreamcasts that would fit there. i might have a few i could send you.

I have some old CPU fans from Pentium 3 computers. They are pretty small so I will try them. If they don't work I'll definitely hit you up!

How's this for a power connector?

Radioshack has 40mm fans.

Nice work, man! I'm totally putting this on my Portables/Laptops to buy list.

 

[michael_0u812]

Haha nice man. After I finish this I'd like to see if someone wants to commission me for a laptop. I could build one for the price of all the parts plus like $250.

 

[Basement_Modder]

You can get so much more for a PS3 laptop.

Try $2000+

 

[michael_0u812]

Hmm, so I know which pins on the HDMI cable correspond to the DVI pins but I don't know which wires correspond to the pins. I can't find any information on the actual color coding. I guess people don't often cut up HDMI cable.


Time to multimeter everything...


EDIT: Screw it, I'm just gonna shorten the HDMI cable and keep my HDMI/DVI adapter hooked up.

Looking great!

But I thought Linux was impossibly slow on a PS3, is it?

 

[michael_0u812]

It does only have 256mb of ram but I stripped down YDL a bit so it is really efficient. It's faster than most computers that run Vista

I'd love to ditch the 5400rpm laptop hard drive and get an ssd. It doesn't really make a difference in the GameOS but it would sure help linux.

 

[J.D]

If you have $250 you can get a 128GB SSD.

 

[michael_0u812]

Haha I don't even have that! I'm fresh out of my first year at University and I'm already in substantial debt. Good price though
