FPGA driver for PSP screen

Friends are constantly giving us their old electronics. We love it because our junk box is a never-ending pile of possibilities. We’re really starting to amass a collection of LCD screens that are not easily interfaced and this project gives us some hope for the future. [Philip] has been posting about using an FPGA as a driver for a replacement PSP LCD screen.

Many projects source cell phone LCD screens that have their own driver chip that can be addressed over SPI for use with a simple microcontroller. More complicated screens need a more involved control scheme and this is where the Field Programmable Gate Array takes over. [Philip] lays out the steps he’s using to implement his controller, from setting up the correct voltage levels, to planning for coordinate addressing, and even some of his follies with reverse current. We think this would be a great way to introduce yourself to FPGA projects.

PSP plus second stick, camera, 32 gigs

jobless_punk_psp_mod

[JoblessPunk] recently finished his what-a-psp-should-be mod. He’s internalized a camera and added a switch in the body to toggle between using the camera or using the USB port. There’s an additional analog stick, and added charging functionality via the USB port. He’s also packed in an additional 32 GB of flash memory. The device is of course running custom firmware which facilitates the ubiquitous flock of emulators and homebrew apps.

We agree that the original PSP is a pretty powerful handheld that never saw a full realization of its potential.  With the impending release of the next generation PSP Go we hope the price and availability of the older units leads to more mods of this sort. Check out the video after the break. Continue reading “PSP plus second stick, camera, 32 gigs”

PSP Go gets butchered (teardown)

Dx1CSXo13YF3NYBa

Not due to be released until the beginning of October, a PSP Go demo unit (shipped to G4TV) has already earned itself a teardown from [iFixit]. Among what was discovered:

- Once a few screws are removed, the battery is user replaceable (as-in: no soldering iron required)

- Wireless connectivity is only supplied through a 802.11b chip (no update to ‘n’, or even ‘g’, by Sony)

- Almost all chips are EMI-shielded (making them a bit more annoying to get to)

With a cheaper version of the PS3 ready to hit shelves, one can only wonder whether the relatively high price tag on this new PSP is worth it.

Update: It seems as though no party involved wanted the info leaked this early, which explains why the video and picture gallaries (up courtesy of Google) have been removed.

Update 2: The article (linked above) and video are now available. An explanation on why Sony had them remove the items for quite some time (plus some repair manuals) was posted by iFixit.

PSP laptop

30j0m1l (Custom)

[Folklord36] on the Acidmods.com forums has been working on a PSP laptop that we think gives the PSP GO a run for it’s money. Sure it may be a bit bulkier but it has a full keyboard, thanks to an Xbox chat pad. The original psp is on the bottom. The screen and speakers have been moved to the top. He says there are still a lot of things that need to be finished, but this is pretty impressive already.

New PSP leaked

psp_go

Engadget has video from the June 2009 episode of Qore that shows the new PSP Go. It has a slide out gamepad, 16GB internal storage, bluetooth, and a memory slot of some sort. We’re naturally curious about its potential as a homebrew platform. Will Sony take the mature route they did with the PS3 and let you run Linux or will they continue the firmware arms race the PSP is known for? We’ll be hearing more about this platform at E3 next week.

Mouse for your PSP

[TokyoDrift] has added mouse support to his PSP. He’s using a microcontroller to interpret for the PSP, through the serial port. You can see in the video above that this provides a functional mouse control, especially useful for first person shooter style games. He’s got lots of details as well as schematics available in the forum posts. We’ve seen other controllers added to the PSP, but this is the first time we’ve seen a mouse.
