Cool! Glad to hear you got it ok, and installed. I've been working on updates to Narsil, some details posted here: https://budgetlightforum.com/t/-/39069/1709, but I'm still in progress, and still hunting down a bug FmC has been seeing, his mod thread here: https://budgetlightforum.com/t/-/40493, but dunno if it's hardware or firmware yet - I've been unable to reproduce it.
I know you have, or will have your own plans for e-switch software on a 85, but almost wish you could help me on Narsil. Still have more plans for it. I'm at about 75% used code space, so still a ATtiny25's worth of free code space.
Actually - what am I say'n? You already have helped me with Narsil! I stole (borrowed) quite a bit of your code that's in there now

I found this 150 ramping table works pretty well across multitudes of lights, from the pocket/headlamp 14500 Skilhunt H15 to the modded up SRK clones. It doesn't work smooth/well with the the MtnE 7135 based SRK driver, modded out to 50 7135's, because of obvious reasons - he used 380 7135's, so the lower PWM values don't work, and, the transition from 1 7135 to the large bank (49) isn't an incremental step up. This light/driver will require a different table.
I also need to generate a "FET Only" version of Narsil to support LDO based drivers to go in lights like the Convoy L6. From what I understand, the 7135 doesn't work well at higher voltages, and will eventually fail or overheat, so the "FET+1" drivers are not a good choice. Actually it doesn't matter if the 7135 is populated, as long as the firmware doesn't use it.
