If you give presentations often, you will know that one of the biggest headaches is managing slides. You have to figure out software, hardware, and connectors. I’ve usually resorted to bringing a USB thumb drive with my slides in PDF and ODP format, but then I came across an even better idea: the Raspberry Pi Zero W (or RPi0W).
Previously, I had been playing with using Erlang on the RPi0W to control stepper motors, but this seemed more useful. Follow along to see how I created a portable presentation machine that’s about the size of a pack of gum.
