Maker Conor O'Hanlon has shared a build guide for a Raspberry Pi Zero-powered motivational message dispenser, which uses an ePaper display to keep the power draw and desk glare down.
"The Covid-19 pandemic has been hard for everyone. Why not give yourself a break and create this unique Raspberry Pi Zero project," O'Hanlon writes by way of introduction. "This motivational quote bot will display a new quote every hour. It sits on my desk and gets me through the day."
The project is built around a Pi Zero W, which includes an on-board Wi-Fi and Bluetooth radio, connected to a Waveshare 2.13" ePaper Display HAT — an add-on that connects via the Raspberry Pi's general-purpose input/output (GPIO) port and provides a small, low-power electrophoretic display panel.
The software side is written in Python, with the code choosing random entries from a JSON-formatted file filled with motivational quotes. The chosen quote is then rendered as an image and output to the display — while a timer refreshes the quote throughout the day.
The full write-up, with source code, can be found on O'Hanlon's website.
