Hi,
well, I’m probably not flashlight collector (yet? I own something like Convoy C8 host, labeled “Aurora MC-E-C” and newly bought Thrunite TN12), but when I found that some drivers uses ATtiny and read some threads about it here, I become more and more interested (Astrolux S1 & USBASP on the way at this moment :-)).
(I hope I’ll get some way how to obtain 17DDm (FET +1?) itself. As a spare and/or testing).
