lol, interesting & efficent, definitely a parallel, i just say if its not broken, dont fix, there are no protection resistors on any of my 125 LED's either (say vs a few parallel ones i had to add to "plug a leak") against all the threads iv read, but hey, the regulator keeps it all at 5v anyways, in fact i added an uln2003 to boost my currents, so why resist?(actually i did learn my lesson here when i started getting balancing issues on less conductive stages, just barely squeezed through without having to redo it all)
pic is limited at 20ma anyway, no? wouldn't i want my led's at max brightness? why add more limitations?
also i didnt really concern myself on the source side caps since i couldnt see too much ac getting in from my battery anyway..
turns out i did have a capacitor in there aswell, on the output side, unintentionally for the pic, all thats left is to make the heat sink outta washers an a bolt.
