Recommended cheap and nasty 4:3 LCD for bare SE case - 8 or 9"?

[Byrd]

Hi all,

I've an empty Mac SE case and I'd like to try a non-destructive LCD inside with a Raspberry Pi or small PC innards.

What piece of crap Aliexpress or eBay HDMI 4:3 LCD would you recommend - and should I go for 8 or 9" size (seems the 9" screen size is right on the edges while the 8" has a more correct border). 8" 1024 x 768 displays also seem more easy to find/

Thanks

JB

I know this is probably blasphemous, but I have idly wondered about finding a panel that could actually drive an actual Compact Mac's innards. A 1024×768 panel could probably be coerced to do 512×384 somewhat reasonably since it's a clean 2:1 map, too…

If you were aiming for pixel doubling you'd want to make sure the screen was smaller than the opening to avoid physically obscuring some pixels - a 7" or so LCD is probably a good size?

I think a member or two were looking into a switchable LCD panel/CRT replacement a while back. My only offer to make this non blasphemous, apart from not chopping, is I’ve access to a large vacuum press (healthcare use normally) and keen to see if I can make a thin curved Perspex panel over the top of the LCD.

Some folks seem to have had luck using hoglet et al's rgb2hdmi as an indermediary here.

I did a bunch of panel shopping last year and decided HJ080IA-01E to be the best option for physical size, resolution, availability, etc. I was planning to make an lvds driver circuit for it but haven't yet. It would be perfectly fine paired with an hdmi driver board and rgb2hdmi as well.

 

[Phazmatis]

Here's a crazy idea: There are these ultra-mini handheld projectors (which are kind of expensive right now). Perhaps one could be rigged up to do rear-projection onto a translucent plastic "screen"?

 

[Byrd]

Thanks all for tips - @Scott Squires that does looks like the kind of cheap and nasty LCD I could work with! Looks like it can be picked up for $60 AUD with controller, thank you

HJ080IA-01E

Coincidentally, I've been playing with the exact same LCD panel recently. On eBay, it cost me about $37 USD shipped from China, so it was a pretty good deal. I think that the screen's IPS panel looks very good, especially for the money. Even though the resolution is relatively low, it works out okay because the physical screen size is small. I haven't yet had the chance to see how it would look inside a Macintosh bezel as I am using it to build one of these: https://www.thingiverse.com/thing:4846997

@Byrd @Corgi Adrian's Digital Basement has a video about directly connecting an LCD to the TTL output on a classic Mac using a custom RGB2HDMI tophat on a Raspberry Pi.

Here is the diagram I made for the HJ080IA-01E panel. The black area is the compact Mac's physical screen opening. The purple box is the panel's physical size. The blue box is the panel's display area. The green/white box is the physical size of the panel's display area when letterboxed to a compact Mac resolution of 512x342 (pixel doubled to 1024x684).

So, I was wondering - I have a Mac SE with a burned-out flyback transformer. Does this mean that I could replace the CRT with an LCD like this and then I wouldn't have to replace the flyback?

 

[Scott Squires]

That's correct. You can rip out the CRT and analog board and install the LCD (and driver board) in their place.

No, you'd need a great deal more hacking to completely replace the CRT in a compact Mac. Have a look into RGB to HDMI adapters, understanding video outputs, removing analogue board and/or components (leaving an arcing flyback is not a good idea), it's not going to happen easily.

Hi Byrd (and Scott), thanks. Fortunately, I did plan to remove the arcing flyback So, it is a list of the kinds of things you were talking about that I'm referring to.

I think the Adrian's Digital Basement video linked earlier talked about the website for the analogue circuit boards. I think I'd still want the speaker.
