Overview
This project is a recreation of Rune Kyndal’s project featured on HACKADAY.IO. The project removes the electronics from an old HP 95LX DOS handheld PDA and adds new electronics with a Raspberry Pi Zero as the main component. My design is a bit different as I want the screen to be the same format as the original HP 95LX and to include a working touch screen and a real time clock.
