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: The Github page for the project: https://github.com/MakersFunDuck/Hans...

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. ▬ Contents of this video ▬▬▬▬▬▬▬▬▬▬ 0:00 - Intro & summary 0:50 - Tips to get them for free 1:38 - Doom! 4:42 - Start of the projects 4:42 - Subscriber counter 6:09 - Weather forecast 7:09 - Home assistant 9:37 - Internet modem monitor 10:36 - Bitcoin - Stock tracker 12:00 - Post it notes viewer (Google keep) 13:22 - Morning routine viewer (Google Calendar) 14:13 - Garbage collection dates viewer 14:48 - Troubleshooting
