PiWrite is a tool that allows you to use your Kindle Paperwhite as a writing device with a vim-like editor. It involves setting up a Raspberry Pi Zero W, pairing it with a Bluetooth keyboard, and configuring it to function as a webserver. The author was inspired by SolarWriter but wanted a more streamlined experience without the need to set up a hotspot or keep the screen on. PiWrite is open source but the author prefers a reduced feature set and is unlikely to accept contributions. Installation instructions are provided, along with tips for setting up the Raspberry Pi Zero and pairing with a Bluetooth keyboard. The Kindle browser has limitations, and the author encountered challenges in implementing certain features. Development of PiWrite was done across different devices.
