Apple Lisa 3d Case Project

[phunguss]

Some guy did just recently 3d print a full scale Lisa

Here is that Pi case at 325% and thinned out. It will probably be easier to modify this model than recreate from the 3D scanned version.

Agreed. Some parts could be seamed with minimal visual impact, but the front panel is still an issue. There is room to shrink it further to fit inside a 300x300x400mm build volume of an old CR-10 or 350x350x350 K2 build volume. Further shrinkage may make the 9.7 screen appear disproportionate, but an original 12" to 9.7" conversion should be 80.83 percent.

Percentage may be off:
- Specs for LCD and CRT are not the same. Tube diagonal is not equivalent to LCD dagonal.
- Need to consider how much larger a 9.7" screen would be than an 80 percent opening for a 12"diagonal CRT
- Display area of an LCD is the tuge diagonal vs. the display area of a 12" CRT.
- The front bezel covers a portion of the CRT.
- The diagonal of the "12inch" bezel opening is only 11 5/8 inch.
- The "pixel field" diagonal is less than that.
- "Squared up" LCD opening dropped back from surface of the front bezel a tad more than 1/4" yields a diagonal of 11 7/8"
- So your baseline for scaling would be something like 11.875" -> 9.7" yielding a scaling factor of at least 81.68 percent
- Still wouldn't look quite right with no Start/Stop/Front Porch/Back Porch blanking areas surrounding the Lisa image
- Assuming my caffeine deprived brain is up to snuff for this.

All measurements are from my Lisa2 bezel with pencil scribed setbacks. A 12" LCD won't work in it for same reasons.

Thanks for those measurements. I think we still need to wait for word if the LisaFPGA can even output to 1024x768 over HDMI, as the documentation seems to show that it outputs full 1080p. Not sure if an iPad control board scales higher HDMI signals down to 1024x768.

Angles for setback of display are different. Sides are steep, Top is more shallow and bottom is very shallow.

Are you taking that into consideration? Matching the multi-angled framing of the LCD would enhance the look, being more natural.

Note lines in pencil, Strange bulge on bottom curve screws up adaptation of stock bezel to LCD. Would probably need an 11" 3:4 panel.
