So a schematic, pcb and sourcecode is useful.
Thanks Texas Ace for the sourcecode.
This is even more than I expect. I had DOA lights already. :smiling_imp:
I need to get my butt in gear and put the driver together for release but I have just been too busy / lazy to get around to it since it is only for this one light and the light already has the same driver installed.
Texas_Ace: do not stress on my behalf
My two GT_mini’s work perfectly. But there will come a day when they are not working perfectly.
Greatful for the time people spend on posting information on the parts in the GT mini.
Yeah, I have a few drivers I need to clean up and release. They are 95% ready but that last little bit of preparing it for the public is really annoying lol.
Happy Chinese Mid-Autumn Festival 
Its happy broken light for me actually and a few 
can you help me ? where do I get this driver?? or could I use the astrolux s42 driver or another flashlight that makes it easier for me to get the driver? the lantern of a friend came with a defect and I’m trying to help him
