I haven’t kept super close track but I think 11/29 might be the latest. That’s what I have in my lantern. The only noticeable changes are SOS, and I think improved button press stability.
There have been two since 11/29. I dont know what the changes are but I suspect one of them enables C to C charging. The wires were long enough and I flipped over my driver my driver to flash 2020-03-18.
Took all of 5 minutes but it was a little off putting when Sofirn comes in here and states you only have to ask for the latest and when you ask you still dont get it.
But its more than that I have not had Sofirn get a single order right all year.
I ordered a SP10s w/batt and charger, did not get the batt and charger.
I ordered Q8 Anduril I received the older style Q8 with the flats on the body and Narsil UI.
Do they even bother to do more than glance at the orders?
I do appreciate the great lights at great prices, that’s why I keep giving them my money but for gods sake will it cost them money to get it right?
I’m not 100% sure, but I doubt any fw update will change the way the light charges I don’t believe any pin on the controller interfaces with the charger chip. I’ll happily accept correction on this opinion.
No. The firmware is completely unrelated to C-to-C charging. That’s entirely a hardware matter, and cannot be affected by firmware on the attiny85.
As for firmware though, some changes relevant to the lantern are:
2019-09-24: Added version check function (15+ clicks from off), and an automatic ramp-down if button is stuck.
2019-09-28: Added automatic lockout if button remains stuck long enough.
2019-10-02: Increased brightness of LT1’s muggle mode ceiling.
2019-11-18: Added SOS mode.
2019-11-19/20: Rewrote interrupt handling system to fix several infrequent issues like occasionally missing a button click while asleep. This also changed how it handles electrical noise conditions, by making it attempt to boot normally after an error instead of staying in a blinking error mode.
2019-11-29: Adjusted LT1 tint ramping brightness correction formula (was using measurements from a prototype, adjusted to match people’s reported values for production units).
2019-12-03: Adjusted LT1 tint ramping brightness correction again, based on more accurate measurements. Should keep power use and brightness closer to flat while changing the tint now.
2020-03-16: Rewrote all ADC-related code. Almost no effect on the lantern though; basically it should just make voltage readouts more stable.
2020-04-13: Recalibrated internal timing loop; time-based functions like strobe and beacon should be a little more accurate now.
There were lots of other changes too, but not relevant to the lantern.
Seeing as how colored versions are now problematic due to constraints, here I am voting again for focusing on adding the powerbank feature. Seems a waste to lug around 4x18650 and not be able to dip into those power reserves if light is not needed in a particular situation. Nitecore and Fenix both have lower priced lanterns with powerbank features so shouldn’t too much of a stretch. Thanks again!
Finally pulled the trigger on this. As a diehard camper (many times solo), I’m really looking forward to receiving this.
Currently I have a Coleman propane lantern (large, delicate, propane is bulky, noisy), a Coleman LED 4xD battery lantern (large, batteries suck, cold white), and some cheap Amazon 4xAA (bare cold white LEDs makes for extremely harsh light).
Awesome. Thanks for creating this light man! We’ve been using it almost every night on its lowest brightness mode when we’re watching movies. It’s nice to be able to see our snacks and find the remote when needed.
