$100? hmm this price may not be that bad though, considering the display seems to be the most expensive aspect and I'm not finding a similar price/size on Amazon.
One thing I want to learn/address personally is a charging circuit so I'd rather build it myself. Still it is nice to know this is out there ready to go.
Also I have to use these ESP01's I bought haha. The code itself I imagine wouldn't be difficult eg. an http get request firing at whatever interval to your own local/remote endpoint. Would have to see about the ESP driver part to display to eInk.
The price definitely seems great for the size of the display, but it might be worth looking at the Waveshare e-paper displays if you want to do something a bit more DIY.
