Cyberdecks
This dual-screen luggable was featured on Hackaday https://hackaday.com/2020/06/03/a-dual-screen-luggable-with-integrated-rtl-sdr/. I was excited by the Raspberry Pi 4's dual HDMI out. The keyboard plate was cut on my CNC, and is hand wired using QMK. The deck no longer has the RTL-SDR in it.
This small screen unit was built on my Dormouse keyboard. It has a Pi Zero W in it, along with a Pimoroni Hyperpixel display. The pi was modified to use an external wifi antenna, following this tutorial: https://www.briandorey.com/post/raspberry-pi-zero-w-external-antenna-mod. The keyboard now fits a USB hub, Adafruit charger, and a lipo battery. This one is cool, but it is quite underpowered.
