Nico, I think the Seanna is a bit difficult to come by… seems they were over $60 even a few years ago.
David, the PZL is a 2 channel driver built with all 7135 chips, so it’s easy to set the regulation value within the scope of the White Flat. The reason it’s called puzzle is that the text indicating the components sits inside the ATTiny pad, so if you put the ATTiny on first the rest of it is a puzzle.
People still use em? Well, with the resurgence of these Osram emitters the need to keep current controlled brings back even the Qlite’s. Besides, I’m not people….
Just looked at the thread again for the PZL driver. It just reminded me that not only was wight always coming up with the latest and greatest drivers back then, he always stubbornly insisted on his drivers being aesthetically designed as well. Things had to line up, have symmetrical spacing, etc. Every driver was a work of art!
Yep, comfy set the stage, wight wrote it down in traces. The old HD2010 drivers were the inspiration as I recall - pure spring melting, LED desoldering power!
I really don’t want to know exactly how much I’ve spent on driver components, boards, li-ion cells and flashlights. I don’t. But I know it’s in excess of (Edit: lets just say it’s excessive).
Speaking of the hateful HD2010, I once took this outside of the box approach to bring the emitter into the reflector for proper focus. That was the light that started me modding, it didn’t work right out of the box and the extended process to get it working and working well taught me a lot… lol
Yeah, back then I couldn’t understand anything you guys were talking about with those drivers, so no surprise I don’t retain any knowledge from those times. I “remember” the knucklehead driver, but I don’t know anything about it unless I go back and read about it again.
I kinda got pushed into thinking about these emitters a little while ago, and the idea came to me to use the White Flat’s in a reflectored triple. I like small well made lights, anyone know where I can get a good price on a Brass MecArmy PT16?
I put something together
testing out the right values for the CC part will need some testing
the 2 blank copper areas are to solder a piece of copper wire likely hammered flat to spread heat better
I put one together, albeit much more rudimentary than yours. 5x CN5710 (dual channel: 1+4) for 5 amps linear. Working good so far. Without any reflector height tuning, got 958 lumens & 273k lux with a Flat White 1mm² (vs 1540 lm & 127k lux stock driver with XP-L HI)
