Ben Krasnow Hacks E-Paper For Fastest Refresh Rate

[Ben Krasnow] is known for his clear explanations alongside awesome hardware, being one of only a few hackers who owns an electron microscope. This time he’s explaining how E-paper works while modifying the firmware of a 4.2 inch E-paper module to get a higher refresh rate. As for the awesome hardware, he also analyses the…

Hackaday Prize Entry: PaperBack Desktop ePaper Monitor

When we announced the Hackaday Prize with its Best Product category, [PK] polled his wife and co-workers about the idea of making a desktop monitor using 6″ 800×600 ePaper, which he has since built and calls the PaperBack. One such requirement for a monitor is to be able to connect to it using one of…

Health-Monitoring Flexible Smartwatch

Hackaday Prize Entry: Health-Monitoring Flexible Smartwatch

[Nick Ames]’s Flexible Smartwatch project aims to create an Open Source smartwatch made out of a flexible, capacitive e-ink touchscreen that uses the whole surface of the band. This wraparound smartwatch displays information from the on-board pulse and blood oximetry sensor as well as the accelerometer and magnetometer, giving you a clear idea of how stressed…

Hackaday Prize Entry: WiFi ePaper

[Frank Buss] designed an electronic version of a sticky note: a WiFi enabled, solar-powered ePaper, with magnets embedded in the casing. It’s based on the new ESP32, and the idea is that you can update it via your smart-phone or over the internet via a cloud app to show any message you want. Being an…

E-ink Display Driven DIY

E-ink displays are awesome. Humans spent centuries reading non-backlit devices, and frankly it’s a lot easier on the eyes. But have you looked into driving one of these critters yourself? It’s a nightmare. So chapeau! to [Julien] for his FPGA-based implementation that not only uses our favorite open-source FPGA toolchain, and serves as an open reference implementation for anyone else who’s interested.

Watch the E-Ink controller in action:

Design files and source code are available on GitHub:

E-Paper Breakout Board for Teensy

Breakout board designed in KiCad to connect Pervasive Displays 2.15″ E-Paper (E2215CS062) to Teensy 3.2 or Teensy LC. Based Teensy E-Paper Shield by Jarek Lupinski in EAGLE.

My goal is to create a name badge I can wear at conferences and Maker Faires. This was first step to verify the KiCad schematic and KiCad footprints work. I will post more information as the badge project progresses.
