I absolutely encourage exploring and experimenting, but I wouldn't call the current state (even now) of driving those displays easy. I had a few such displays (and have a decent amount of experience with electronics and reverse engineering), but they differ in subtle ways, and since no comprehensive spec sheets are available you end up futzing around a lot to get it to work. I used that essentialscrap link as well as spritesmods (both excellent resources) and any other little tidbits I could find but it still took lots of iteration until I could even get anything displayed! Not to mention from a technical perspective, driving the displays takes 5 different voltages, 4 of which are fairly atypical. Still, they're really cool to mess around with, and cheap on eBay :)
