What did you mod today?

I haven’t actually modded anything, but I have assembled 4 - LH351D 4000K LEDs on an mcpcb, a led4power LD-A4 driver, a Li-po 3700mAh cell, a switch, a 2 amp TP4056 charger and USB-C port plus a Convoy S2 pill and some copper pieces, into a test configuration for a light I am thinking about making.
