#17 Using e-ink (epaper) Price Tags (Shelf Labels) for everyday needs

Recently I realized my local grocery store replaced traditional price tags with electronic e-ink (epaper) price tags / shelf labels. I found out that you can easily buy the same ones from e-bay, and I was able to re-program / hack them.
These devices can be used as cheap Arduino E-Ink Displays, and you can easily program these with usb-TTL adapter, or any Arduino board.

In this video, I will show you how you can use them for everyday needs.

The brand of the e-paper display I re-program is Hanshow, and the model is Stellar.

Here are the links which is mentioned in the video:

PS. I made the doom part of the video with the tool that I explained. I only the modified code to take a picture at the end of one loop. I made a time-lapse video to remove the screen refresh artifacts.
