IMac Flatscreen Conversion Bezel Retro RPI4 Project

Last crawled date: 4 years, 4 months ago

This is a bezel to convert an old IMac to a flatscreen display since the old display is a CRT monitor there needs to be a round bezel on the flatscreen to fill the gap.
This started as a project of mine to run a raspberry pi 4 in a IMac case. I wanted to upgrade the monitor to a flatscreen so I took a screen 14.1 inch from an old macbook(see parts list)
First I stripped the IMac of its internals, keeping just the case (see pictures). I added some kapton antistatic tape inside the IMac case to insulate the interior metals from the exposed controller board. I printed the laptop screen bezel and glued it in place to the Laptop screen metal bezels using epoxy. I then glued the 3d printed bezel to the IMac case at the corners using quick set epoxy. Lastly I attached the Raspberry Pi to the Laptop screen controller board and the screen. Fires up running Raspian.
PARTS LIST:
Laptop screen model # LTN141P4-L04 (ebay about $17)
Laptop screen controller board for #LTN141P4-L04 (ebay about $25) - This is the small controller board that connects between the raspberry pi and the laptop screen via HDMI
Controller board power brick (ebay $8)
Old IMac (found via craigslist)
Raspberry Pi-4
Printing Instructions:
Print in black to hide imperfections, I used .2 layer height and 20% infill. Print two of file labeled laptop_screen_sides.stl and four of the laptop_screen_top_half.stl. Glue these together into a single frame and then glue it to the metal bezel of the screen using epoxy or superglue (I suggest epoxy).
