IMac Flatscreen Conversion Bezel Retro RPI4 Project

thingiverse

This is a custom bezel to convert an old IMac to a flatscreen display since the old display is a CRT monitor, requiring a round bezel on the flatscreen to fill the gap. This project began as my personal endeavor to run a Raspberry Pi 4 in an IMac case. I wanted to upgrade the monitor to a flatscreen, so I took a screen measuring 14.1 inches from an old MacBook (see parts list). First, I removed all internals from the IMac, retaining only the case (view pictures). I applied some Kapton antistatic tape inside the IMac case to insulate the interior metals from the exposed controller board. Next, I printed the laptop screen bezel and secured it in place using epoxy on the Laptop screen metal bezels. Then, I attached the 3D-printed bezel to the IMac case at the corners with quick-set epoxy. Finally, I connected the Raspberry Pi to the Laptop screen controller board and the screen. The setup boots up running Raspbian. PARTS LIST: Laptop screen model # LTN141P4-L04 (available on eBay for approximately $17) Laptop screen controller board for #LTN141P4-L04 (available on eBay for about $25) - This is the small controller board that connects between the Raspberry Pi and the laptop screen via HDMI Controller board power brick (available on eBay for $8) Old IMac (found through Craigslist) Raspberry Pi-4 Printing Instructions: Print in black to conceal imperfections. I used a .2 layer height and 20% infill. Print two of the file labeled laptop_screen_sides.stl and four of the laptop_screen_top_half.stl. Assemble these into a single frame by gluing them together, then secure it to the metal bezel of the screen using epoxy or superglue (I recommend using epoxy).
