We’ve known for a while that you can buy interface boards to turn old laptop screens into standalone monitors, but complete sets with 4K panels and control boards are also now becoming widely available on sites like eBay and AliExpress, and prices are dropping. These sets are also available with low-profile connectors like micro HDMI and USB-C, which allow for some very compact builds.

[Matt] from [DIY Perks] used one of these sets to build a slimline USB-C monitor with a brass enclosure. Video after the break. The enclosure consists of brass sheets and U-channel pieces soldered and screwed together. There is quite a bit of residue and discoloration after soldering, but this was removed with a bit of sanding and polishing. A pair of adjustable legs were added to allow it to stand on its own, and an additional chamber on the back holds the control board, an old smartphone battery, and a battery protection circuit. [Matt] also added a pair of removable speakers, which are sealed speaker units covered in brass mesh and plate.

We’ve covered several DIY monitor builds over the years, and they are perfect as an additional monitor for a laptop, or for pairing with the Raspberry Pi 400 with its integrated keyboard. We really [Matt]’s builds, which include a smartphone-based 4K projector, and a very effective cooling system for an expensive DSLR camera.
