Apologies if you've already come across these, but I have in my own searches found some wider format touchscreen displays close to MP900 size, this for example:
https://www.waveshare.com/7.9inch-hdmi-lcd.htm
Or this:
https://www.aliexpress.com/i/1005001399366027.html
Both would seem to be able to fit inside the lid of the MobilePro
(with some mods possibly
), annoyingly the smaller of these two is the higher resolution, though both are a good bit higher than HVGA resolution.
I've found multiple LCD candidates minutes after the keyboard reply was posted -- and I'm all for higher resolution.
You actually linked the very one from aliexpress that I saved just over a day ago. That would be perfect.
My main problem with that is the touchscreen cable and where to attach it to /see below/ the raspberry pi.
EDIT: Although that very panel is $75 and I can't seem to find it anywhere else. Kind of expensive for such a panel...
Yes, the idea is for me to gut the MobilePro's main board and LCD, and potentially have something 3D printed to align the screen, and potentially a few buttons on the side of the screen [hotkeys maybe??] if space allows for it.
Having modern internals would be pretty sweet. I've went ahead and ordered a
raspberry pi zero w, because of it's ultra-thin profile, along with a
trinket m0 (for keyboard handling - unless I can get the pi zero w to handle keyboard matrix stuff
). I know I can figure the pinout of the keyboard myself with a multimeter.
The PCMCIA slot could become a
storage tray, as there are some pretty cool gadgets like
PCMCIA stash cards that let you put some small stuff in them.
CF card could be potentially converted into a primary/secondary SD slot if a 3D bracket is designed and printed.
I don't think there would be much to do other than print some parts to get everything situated.
My main thing is that I do not currently own a 3D printer, and know just a small bit about the dynamics of 3D printing.
I'd love to be able to maintain the USB host port too. The only thing missing is bluetooth, really. The headphone jack can be hot glued, although that makes my skin crawl thinking about it...
Still though, waiting for a chance to get a couple 18650Hs spot welded so I can rebuild the battery pack.
I welcome any criticism of this plan, and suggestions don't hurt either. But turning the MobilePro back into an actual Pro Mobile device [see what I did there?] would be rather epic if I say so.
