Stratis Lumina Inspired Keychain Light (Scratch-made Light)

This is my first thread, and I don’t speak English, so please be gentle.
First, I want to thank the BLF Forum and all members here, I’ve learned so much from you all, I’m an active reader here.

I’ll share my mod here, I’m a fan of e-switch light because of it’s Firmware (Narsil & Anduril)’s due to its rich features, and a built-in rechargeable light.

Here’s one of my latest mod, Inspired from a thread by CRX , and this took me almost two weeks to finish and I’m very happy with the final result. I call it SLMicro Clone, or SLMicro II (CRX will sue me)   Smile


  • Sandalwood (Aromatic Wood family)
  • 1mm thick brass sheet
  • 200mAh Li-po battery 751723 30C
  • 16mm sanded Copper DTP MCPCB
  • 3mm thick copper chunk soldered under MCPCB
  • 9.8mm diameter glass lens and OP reflector (taken from Singfire SF-364 AAA Bullet Flashlight)
  • handmade 12mm brass reflector bezel ring
  • M2 brass removable nut screw (for lanyard/keychain)
  • PC-Clear Epoxy, Dextone, & Superglue

Parts (Driver, Charging Circuit, Switch, & Emitter) :

  • 0.8mm thick Driver PCB (taken from 18650 protected circuit board, and stripped of all its parts). Attiny85 MCU and Charging component is solder jump together (most are airwired).
  • E-Switch PCB is taken from TP4056 charging module.
  • Attiny85, AMC7135, and tiny Mosfet (Dual-Channel)
  • Blue 0603 Narsil standby indicator LED
  • Red 0603 Charging indicator LED
  • TP4057 Charging IC (set for 0.15A charging current). Charging voltage is terminated at 4.19V (It’s perfect to me)
  • Female MicroUSB Socket (taken from TP4056 Module)
  • Emitter is XP-G2 S3 1A 6500K (I’m a fan of cool white). I could use XP-L W2 but the reflector opening hole need to be widened, and I like the XP-G2’s beam pattern a lot.

Specs :

  • Size : 12 × 25 × 40mm
  • Weight : Not measured yet (it’s quite heavy)
  • Material : Natural Wood & Brass
  • Emitter : XP-G2 S3 1A 6500K Cool White
  • Brightness : 750 Lumens Max(Turbo)
  • Mode/Firmware : Narsil 1.3 Ramping Firmware with Blue Standby Indicator LED
  • Micro-USB Charging with Indicator LED
  • LVP Battery Protection
  • Batt & Temp reader (calibrated)
  • Removable Lanyard/Keychain Screw
  • Tail stand capability
