Raspberry Pi 400 powers dual-display retro-gaming console

DIY Enclosure Raspberry Pi 400 console

“Block after Block” has designed a dual-display tabletop retro-gaming console using plywood edge grain and a Raspberry Pi 400 keyboard PC that allows players to physically face each other during a fight or other gameplay. While there’s a galore of projects based on Raspberry Pi SBCs, the Raspberry Pi 400 keyboard PC is more like a consumer product due to its form factor, but Block after Block integrated the PC into its own retro-gaming console which involved a lot of woodworking skills and installing RetroPie on the Pi 400 device. This DIY project mostly involves spending time in a workshop cutting wood, and once you’re done with this part, it should be pretty straightforward. The following items are required for the project: A Raspberry Pi 400 keyboard PC Two monitors (second-hand monitors will do) An HDMI splitter to mirror the output from the Pi 400 along with a micro HDMI […]
