The Fenix L1P is a well built, bright and pocketable light. It is however mandatory :naughty: for a modder to tweak the light for more usefulness. So I am posting my first Fenix L1P mod greatly inspired by cpf member djpark's Fenix L1+ AA Light Mod with POP2 :rock:.
My mod consist of an extreme engineered circuit board milled in high precision, an ATMEL AVR AtTiny12V microprocessor, IR HexFet, a cap and a resistor. Yeah 4 parts, this is no wimpy mod I assure you. I don't have a million dollar workshop so most stuff I did are done by simple tools.
I used an ATMEL instead of Microchip PIC because I am a AVR guy, I am totally noob when it comes to PIC. And my AVR goes down all the way to 1.8Volts which is good for 2AA applications. The rest are basically similiar to the well known POP2.
My software has 3 levels of brightness, strobe and survival mode. Which is what I really only need. Writing your own software to customize your light is so cool you guys have to try it.
This mod exploits the momentary off switch which is also found on the Nuwai Q3. The microprocessor switches the HexFet on and off which means PWM which also means there is no boost as there is no inductor so a 14500 Li-Ion is a must. During direct drive(sort of, with very little resistance through the HexFet), I see a little increase in brightness when compared to a stock L1P v2.5. Much but not significant. I have yet to change the R bin Luxeon to a LuxIII. A SQ17 reflector might fit too. Maybe tommorow...
I know you guys dig for pics so here you go...
Check out the extreme engineered double-sided cicuit board with CAD
Cell + side. Lines drawn with bic pen. Cleaned with rubber eraser easily.
Just like drawing in kindergarten, how fun .
Milled with high precision tools .
Blur image :sigh:, tsk tsk
Yeah that's what I am talking about... Freeform circuit
Stock Fenix L1P 2.0 on the right
Stuff it all back in to the brass module.
Update:
Original Fenix 2.0 reflector IMS 17mm Reflector
Same height, need to trim mounting legs.
Far Right - with 17mm IMS Reflector, a bit smaller in diameter and some farkle bonus :shrug:
Left - Stock Fenix L1P v2.5
Right - Direct Drive(96% duty) stock L1P v2.0 Luxeon with IMS 17mm reflector
Left - Stock Fenix L1P v2.5
Right - Direct Drive(96% duty) LuxIII TWOJ with IMS 17mm reflector
Sorry camera white balance went crazy...
If you want to see some stock electronics of the Fenix L1P v2.0 picture read it here where the Fenix L1P v2.0 get naked. There have fun.
