Huh, what an interesting project.  Took me a little bit to figure out why I'd want it.  I admit though, it would be nice to just have a GB shell with a cable coming out of the bottom to act as display and control for the NES.  Or PC-Engine, or any of the other applications. wink  Nice work!

Cheers! big_smile

How do you power the lcd ? via a separate supply ? usb ? I'm looking for a cheap way to add a lcd to the rpi.

/M

I was thinking this might be cool with a Raspberry Pi and lo-and-behold you have a video of that on your site. Might it even be possible to fit the RPi into one of Kitsch's new cases if the battery compartment were removed?

^ or if i removed the battery compartment altogether on an alternative back? 

would it fit then?  with room for a li-po battery pack too possibly?  (i don't have one yet)

just curious.....  i may/maynot by considering something like that

Totally possible - somebody even went to the trouble of making a 3D-modelled video with cheesy music to demonstrate the possibility! smile

(Bear in mind though, that if you remove the battery compartment then you are also removing the support posts that sit behind the buttons...)

An alternative back-half of the case mold would be a truly awesome thing kitsch!! big_smile

You could customise it to add holes in the right places and the right shape for the Pi's connectors - and if possible, adding a little extra depth could make a big difference!

There is a nice thread here http://bit.ly/RasPiBoy by the creator of the above video with some good pictures showing different possibilities for fitting the Pi into a GameBoy:

Yes, I am using a separate power supply - these little screens are usually intended to be used in a car, so are designed to be powered by the car's 12V battery. Depending on the particular screen you buy some people have had luck experimenting with supplying lower voltages - or have found that their screen was regulating the 12V down, and so were able to supply a lower voltage and bypass the onboard regulator. The USB ports on the Pi are notorious for being under-powered though, so you would need to add in a powered USB hub if you wanted to try and run the screen from USB power...

i'm all about this. was just commenting on piggy faq about rasbian, and this could be an awesome solution for using the powerful Rpi for piggy. the form factor would be right up my alley. this would be made very attractive if you buckled down on a source for some confirmed ease-of-implementation LCD screens for people looking to buy your product and build it in a DMG case.

this is amazing ! good work man !

...the best sources of information on suitable LCD screens are modding forums, which often have whole sections dedicated to sharing experiences and recommendations for potential candidates:

http://forums.benheck.com/viewforum.php?f=8
http://forums.modretro.com/viewforum.php?f=6

And as I mention on the project page, there are also sources available where you can buy just a bare LCD + controller board, and know what you are getting without having to dismantle a screen to find out what is inside:

http://www.adafruit.com/category/63_110
http://www.aeicomp.com/

I don't feel like I can give an informed recommendation because I only bought two different screens to try, and out of those two I decided to use this one:

http://feeldo.net/products/139-digital- … ensor.aspx

Which I am very happy with, it is a great fit, and the display looks good - but I wouldn't necessarily want to recommend it because the LCD is hot-glued to its enclosure which makes disassembly a bit less than straight-forward! (a little isopropyl alcohol does work wonders for 'de-activating' hot glue though!)

The other model I bought was a 'Pustom' 2.5" LCD, which isn't glued together and comes apart easily without any fuss - this model is well-documented on the modding forums I mentioned earlier:

http://www.made-by-bacteria.com/forum/v … amp;t=1986
http://forums.benheck.com/viewtopic.php … mp;t=31251

but it is a little bulkier and would require some modification to the GameBoy shell so I decided against it - I would be happy to send it to you for free if you think you might use it?

Another thing to consider is that the Raspberry Pi also has a 'DSI' connector for interfacing directly to an LCD, rather than using the composite video output - but unfortunately the firmware doesn't support it yet and the most recent and optimistic estimate is that we still have half a year to wait:

uXe - very interested in LCD, pm'd.

I'm missing something.

I'm curious how many units you've got assembled currently. At least one, for proof of concept. In the event that this doesn't get off the ground, I'd love to get my hands on a prototype.

8bitDAD - the LCD is in the mail and on its way to you! ...and regarding prototypes - let's give the project 14 days to finish before we start picking over its bones! wink
