The idea is to turn a Smart Response XE (former classroom gadget, now available for cheap, due to being phased out) into a pocket text editor. There is some evidence such an item may help in writing process, at least with the first draft, so I'm going to try.
There are some challenges ahead, but I hope to have it ready for NaNoWriMo 2021.
The main challenge is going to be the exfiltration of data, currently the only solution I can guarantee is training a neural network to perform OCR right off the screen. But there are options, maybe I'll mange to adapt the wireless bootloader somehow, or fit a serial plug or an usb interface or something inside the case.
