PSPi Version 2.0 - Raspberry Pi Zero in a PSP - Project is Now Complete!

It is a composite LCD, so all that is needed is a composite video wire run from the Pi composite output pin to the input on the LCD driver. It does require a small amount of software configuration to set the correct resolution, but it's a fairly straightforward process.

Check out my build progress to see images of the LCD being connected and soldered.

@adamspc do you have a link were to buy the Lcd and driver ?

@qrayg
The list of materials is posted on the site

The LCD and driver come from here. It has to be disassembled, and it has everything you need. The driver is very small and is a perfect fit for this type of project.

I'm working on more detailed tutorials for the PSPi Version 2. If any parts of my in-progress guide are difficult to follow, I'm happy to make a tutorial for that section. Please let me know here or at othermod.com. Also, I will be continuing work this week on the build, so keep an eye on the site toward the end of the week for updates. Thanks for all the input guys.

Guessing there's little chance for a Pi3? Considering it's a bit more powerful. Love the work and it gets me thinking and even pumped to make one myself c:

@LSolrac2
Doubt it. The Pi Zero at 65mm barely fits, so I don't think the 85mm Pi 3 ever will. Maybe one day we will get a faster Pi Zero.

Here is one for the power switch circuit. If anyone has trouble following it please tell me. I'm attempting to make this easy to duplicate.

For some reason your reply passed me by until a couple of days ago when I noticed it. Anyway, I checked your site out. Great work with the tutorials, I bought the parts necessary to try and make the power switch.

I also bought the LM393 voltage comparator you listed in the BOM but I can't actually see where you used it in the build? Didn't want to get part way and discover it was needed though.

@Pifan
It's funny you asked today. I just finished writing the guide for the LM393. It's used for the low power LED. It can be one of the last circuits added, so you didn't miss anything. I'm adding it to the PSPi 2 page too.

I thought I responded to the audio connector message a while back, but I guess I didn't. Do you know what that connector next to the audio jack was used for in the PSP?

@adamspc It's was for the in-line remote as far as I can tell, but I can't seem to make sense of whether this extra bit dealt with the switch from headphones output to speaker output or not.

Awesome work dude, I'm hoping to undertake something like this soon. Wermy over at http://sudomod.com built a Pi Zero Game Boy and shortly after a lot of his users started building custom PCB which saved on a lot of the wiring and such. It would be really cool to see someone make some PCB to the buttons, power, amp etc that you can just drop in the LCD and the pi zero and be on your way.

Again awesome job!

@johnweland
It's funny you say that. I've been working on designing a PCB that would connect to the PSP's FPC cable and that would include the power-on and low-battery circuits, avoiding the hardest parts of the build.

Would anyone out there be interested in buying one if I have them made?

johnweland

yeah what are you thinking the price out will be?

johnweland

Heck it would be really cool to be able to make the hdmi and usb accessible from the bottom so you could 'dock' it and play on a large TV with a controller, when its docked

@johnweland
It's hard to say. There is a US based PCB maker I've been wanting to try out whose prices seem reasonable. Then I've gotta add at least a few dollars worth of components. I'll update the page once I get some prototypes made and have a better idea of what cost will be. I expect to spend a decent amount of time and money on the prototypes.

I thought about the HDMI too. The HDMI port on my build is pressed right against the thin bottom plastic on the case, so I think it would be doable and would just require some dremel work.

johnweland

Dude I am stoked, I wanted to go a GBA build but it lacks the extra buttons. The only thing this is missing is some how making the trigger buttons and you could play 99% of the games out there that the Zero can emulate.

UGH sooo stoked.

Admittedly I'm a bit of a PCB design noob but if you want ideas or a sounding board to bounce ideas off of, hmu

adamspc

@johnweland
I'm only slightly experienced in PCB design. What is taking me weeks to design would probably take another person hours.
I appreciate the offer to bounce things off of you. I might just take you up on that. If you head over to my site we can start some discussions in the forum I just set up.

Also, the triggers on this PSPi already work.

johnweland

I thought the PSP only had the bumpers and not the triggers (l1/l2, r1/r2 )

I'll head over the your site and forums now, do you want to start the thread or shall I? (probably better if you do)

adamspc

@johnweland
Yea it's just got the one on each side, not the dual setup like the Xbox

I'm starting a discussion in the forum.

markyh444

@adamspc just for the record, I am totally interested in the pcb route if you are seriously considering designing one.

adamspc

@markyh444
It's official, I'm doing it. Too many people have asked so I can't say no. I hope to make it a group activity, so anyone with PCB design experience or anything helpful to add please visit the this forum to participate.
