Hello all,
Just a note that I have started an official interest list for a group buy!
If you are interested, please sign up here: https://budgetlightforum.com/t/-/61834
Thanks to everyone on this forum who have provided great feedback, comments, suggestions, ideas, and support. I'm currently busy working through a detailed datasheet and documentation for the driver and the firmware, so please hang on.
Meanwhile, details of the upcoming group buy are listed in the thread above.
TomE, I get a fair number of requests to build drivers for different flashlights but I only have so much time to work on drivers, and it's a fair amount of development time, effort, and cost for me to purchase my own flashlights etc. So unless the demand is very high, I can't commit to working on different variants. I hope this is understandable. For example, I've purchased 3 FWxx flashlights at my own cost just for the development of this driver, and unfortunately I don't get any sponsors 
Thanks all!
