One of the biggest advantages of electronic paper is that it doesn’t require a constant power source to display a static image. Depending on the application, this can lead to a massive energy savings compared to more traditional display technologies. Of course, the electronics that actually drive the display are …read more

ePaper is an interesting thing, providing a non-backlit viewing experience that is much more akin to reading a book than staring at a screen. The reMarkable tablet is a device designed around just such a display, and [davisr] has been hacking away at the platform. His latest work brings full-fat …read more

[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 signals going to the E-paper using an ultra-fancy loaner oscilloscope.
After starting out with a demo of the firmware in action before and after his modification, he explains how the E-paper works. The display is made up of many isolated chambers, each containing charged particles …read more

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 the usual desktop methods: VGA, DVI or HDMI. Given his previous experience making his own VGA card for the 2015 prize, he went with that. HDMI is in the works.
But it ended up being more than a desktop monitor. He first made a power …read more

[David Watts] picked up an inexpensive Waveshare e-Paper display. He made a video about using it with a breadboard, and you can see it below.
The E-Paper or E-Ink displays have several advantages. They are low power, they retain their display even without power, and they are very visible in direct light. The downside is they don’t update as fast as some other display technologies.
To drive the device, [David] used a WeMos D1 to drive the display. He picked up the 1.54 inch display, but they are available in several sizes up to about 4 inches. The smaller display …read more
[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 ePaper display, the power consumption is greatly reduced, at least if you are cautious using the ESP32.
The final version plans to poll a server once per hour to get a new image to display. Depending on the final size and battery constraints, our guess …read more
Guess what’s going on at the end of the month? The Vintage Computer Festival Southeast is happening April 29th and 30th. The event is being held at the Computer Museum of America and is, by all accounts, a really cool show.
Walk into any package sorting facility or Amazon fulfillment center and you’ll find a maze of conveyor belts, slides, and ramps that move boxes from one point to another. Conveyor belts are so last century, so here’s a fleet of robots.
