Eventually received my Seoul Viosys emitters so some DQG UV mini goodness today :)

What did you do? That doesn’t even look real. If I zoom in a bit it looks better, but the texture at both ends seems like something which shouldn’t actually exist.
Happy to have this thing fire up on my first try. There’s a few small tweaks I still want to make but happy with my first day progress. I’ll save the pics since everyone here’s seen a S2 and my soldering skills are HORRENDOUS.
Yeah, due to the low Vf, there is a high potential for FET-based drivers to turn single 219c emitters into smoke when used with a high-amp cell. It might be a good idea to use a weaker cell there, or use thin wires to feed the emitters, as well as un-bypassing the spring(s).
An old NCR18650A would probably be safe, if you can find one.
Another take on the DQG Slim Ti extension tube lights I've been liking so much lately :)

Added a lighted tail to an EagleEye X2R (with stock driver). First tried without bleeder resistor on the driver and 2x 4.7 kOhm on the tail board (the 6 tail leds are parallel with a common resistor before each set of 3), but that resulted in next mode memory (the driver interprets any length of ‘off’ as going to the next mode). Then I tried 2x 8.9 kOhm, and then 2x 22 kOhm. Still next mode memory. Then I added a 680 Ohm bleeder on the driver (between batt+ and ground) and all was well: last mode memory and a well lighted tail.
