There are plenty of lovely e-readers out on the market that come with an nice big e-paper display. There aren’t nearly as many that come with two. [Martin den Hoed] developed the Diptyx e-reader with such a design in order to better replicate the paper books of old. The build is based around the ESP32-S3, a powerful […]
These days, Internet connectivity is ubiquitous, so you can look up live weather data on just about any device around you. Regardless, [Jozerworx] wanted a simple, clean, independent weather display, and came up with this simple design. The build is based on the Lilygo T5 EPD devboard, which combines an ESP32-S3 microcontroller with a nice […]
E-paper screens have opened up a wide variety of novel use cases that just wouldn’t work with the higher power draw of an LCD. [gokux] thought it would be perfect for a digital sticky note. Using a Waveshare 2.9″ e-paper display hooked up to a Seeed Studio XIAO ESP32C3, a battery, and a switch all […]
If you’re a regular GitHub user you’ll be familiar with the website’s graphical calendar display of activity as a grid. For some of you it will show a hive of activity, while for others it will be a bit spotty. If you’re proud of your graph though, you’ll want to show it off to the […]
Here’s a great hack sent in to us from [Simon]. He uses an e-paper photo frame as a weather map! By now you are probably aware of e-paper technology, which is very low power tech for displaying images. E-paper only uses energy when it changes its display, it doesn’t draw power to maintain a picture […]
[sprite_tm] had a problem. He needed a clock for the living room, but didn’t want to just buy something off the shelf. In his own words, “It’s an opportunity for a cool project that I’d rather not let go to waste.” Thus started a project to build a fun e-paper digit clock! There were several […]
[Lonyelon] wanted to build an anniversary gift for his girlfriend. He decided to say it with e-Paper, a wise choice given its persistence and longevity. The project is an anniversary calendar. It displays a counter of the total time the couple has been together, measured in years, months, days, and hours—so it’s remarkably precise. [Lonyelon] […]
If you’re trying to learn a new language, there are always a lot of words to learn. A word-of-the-day calendar can help, and they’re often readily available off the shelf. Or, you can grab some hardware and build your own, as [daedal-tech] did! The project was built as a gift to help [daedal-tech]’s partner with […]
For almost as long as there have been microcomputers, there have been attempts with varying success to make tiny handheld microcomputers. Sometimes these have been very good, and other times they’ve missed the mark in some way. Latest to find its way to us is the CL-32 from [Moosepr], it’s a handheld computer with an […]
