This lantern could make good use of the Sofirn Q8 extension tubes if designed to fit. Imagine having the lantern fueled with 8 or more 3500mAh cells. Runtime for ever
I had not seen that someone was doing extension tubes (I think). That is a very good thing .I have a Fenix TK75 with three extension tubes. Excessively expensive at the time, but a good light. The first set of 4 batteries is “regular” bedside. The next three sets are sitting (charged) in the closet for when really bad crap has happened. I had hoped the Q8 would have extension tubes; but it did not. This is good news for the lantern and the Q8 if available. I am primarily an emergency light person. We have earthquakes, bad storms, Tsunamis, occasional tornadoes, and forest fires. We don’t have immediately active volcanoes; but there are several in the area. Think Mount St. Helens.
Attention would need to deal with vertical stability with multiple extension tubes. A good stand would fix that.
Will those driver boards be sold separately in your driver sales thread too, for some who might want to mod their existing Q8 lights or other SRK-style lights?
EDIT: I just noticed your (re)programming pads are there, which is cool. But, looking closer, they are interfering with the ATtiny footprint, or rather the ATtiny footprint is interfering with the (re)programming pads.
Looks good!
i agree that this first lantern version don’t need the power bank, just the ramping design & built in charging. The AMC design is perfect for this first production lantern model.
as long as its all in parallel & not any series its doable with up to 32 with extension tubes, to create a taller model that can run for days non stop. (the lantern will be a 4P design)
