2 months ago Hello! Very doable! I would encourage people to try it out.
I kept it out of this project for scope reasons -- getting the power installed, and reading voltage, and writing the code for handling charge/discharge and power control was beyond what I wanted to do here.
But you could definitely add your own battery / lipo by following a guide like that. There are some pre-made UPS solutions for pi projects that would work really well, too. Waveshare makes one, PiSugar makes ones, etc.
How feasible would it be, to include standard lithium cell batteries? maybe one line (3 cells?), between the keyboard and where the wrists reside on the table, or behind the keyboard, or on the sides of the keyboard, ...
basic electronics considerations seem to be here (though I am not sure if this works for bare cells too): https://www.circuitbasics.com/how-to-power-your-raspberry-pi-with-a-lithium-battery/
