Finally got around to adding a “proper” (Gen 2, Rev 5.3 style) tailcap to my Astrolux SS. I just got solder paste yesterday and decided to try that for soldering the LEDs. A little dot on all of the LED pads, placed the LEDs, and put it in a pan on the stove. It worked out wonderfully.
I did 3x blue LEDs and 3x white LEDs, with each channel behind a 20K ohm resistor. Used a 560 ohm bleeder on the Mtn FET+1 driver. Measured draw at 0.1 mA (my DMM only reads to tenths). Looks pretty nice, if I may say so.
In case I haven’t said it yet, thanks PD for putting these boards up on OSH Park. They certainly add a nice touch to my favorite lights.
