My modded switch lite with new shell and joycons! Got these from aliexpress since the original shell was cracked and the joycons had some dead zones. Whole process took about 3.5 hours (with child interruptions). I had some pics of the soldering but seem to have lost them.
If you don’t trust yourself, don’t do it. I did it as it’s just fun to do. But boy was it small. I expected things to be tiny, but I could barely see the points to solder with my eyes. I’ve setup some crappy setup with a camera to be able to see it somewhat. And it worked! But yes, be aware that it’s really small haha
