I'm not really trying to follow any particular one. I know at this point I want a wood box and 5V. That's about it. I like the snap on battery connector from the vid I posted. No muss, no fuss. I definitely don't want to mess with a juicer like the Ali'i. They are nice looking but fancier than I'll ever get.I'm not sure, which project you want to follow now? The Ali'i uses one batt for 3.7v (pretty sure a 18650), or the 2 in series for 6v (where one of the batts is only 3v, not 3.7). Plus it has a juice feed system and I'm not sure if you want that either. The 5v reg is used to bring 2 -in series- 3.7v batts to 5v. Most people leave the 6v where it is. LED later, but what do you want to work with again?
