DIY telescope control system

How can I learn more about DIY electronic controls for DIY telescopes? Surely there's a reason I'm not finding my particular idea represented online.

I've been reading about making my own Dobsonian telescope and I'd want to build electronic control into it from the beginning. I've searched online and have found lots of resources that are very old covering how to use rotary encoders and a known starting position, but I'm wondering if there's either a simpler way, or a reason why I'm not finding anything else.
It seems like getting a sensitive solid state accelerometer and compass then using those references directly to drive some smooth motors with a bit of hysterisis would be an option that wouldn't rely on getting a starting reference and carefully tracking movements from there. Are these things just not sensitive enough? Too much jitter? Something else?
Are there resources I can use that are written recently to take advantage of cheap new electronic components?
