This. Exactly what I’ve been wanting for quite a while. As soon as this is available, sign me up! 
FET, 1x7135, OTC, attiny13/25, and still just 17mm and one-sided!
Is there any chance you might use attiny25 on some of the drivers you build? As far as I can tell, the only drawbacks are no “picoPower” and a slightly higher price.
I believe he will, if I ever get my butt in gear and port the STAR firmware to the 25. But then with the built in temp sensing there will be a lot more code to write even though the current temp sensing program is most of the way there.
Yes. I think that we'll see them ready to go by the end of December or the beginning of January.
JonnyC;
Hurry up PLEASE! Richard has had one of my full house modified M6 lights which he borrowed back for testing and I want it back one of these years. Been gone since Oct 8th so now over 2 months of experimentation and testing with it. Three other lights in his hands shipped the same time that I am waiting for too.
That has nothing to do with him. The code is ready for those lights and working--that's just me being overworked and behind on everything. I just haven't had the time to finish things up.
I had thought it was just a matter of recompiling, but I just tried and it failed. Apparently the attiny25 gcc settings don’t have a symbol for “WDTIE” (and possibly other things), so some low-level bits will need some minor changes. They’re so similar that I doubt it’ll be hard though.
If I had a driver to test on, I’d probably be a lot more motivated to get it working.
I’ll probably have an ATMega32u4 soonish to play with too, but it’s for totally different purposes.

I wants kits. I wants bare board and kits please. :party:
Yeah, I assume a lot of the registers have changed, so it just requires looking at the datasheet.
Richard; Just trying to give a gentle nudge and I thought that JonnyC might be involved when he mentioned code for a temperature sensor. Rather have things right than rushed and I do appreciate your work.
Even if it not flashlight related, what is your plans for your atmega32u4?
USB SNES controller with accelerometer. It should be fun for emulators, and I can put extras in the firmware like per-button turbo and shake-the-controller-to-rewind-emulation-by-5-seconds. Maybe map other random stuff too, like tilting the thing sideways to adjust the emulation speed or tilting up/down to load/save the state.
Mostly, I just think it sounds like a fun project.
hey RMM, how tight is the heat shrink tubing over an 18650 before you shrink it? is it loose enough to fit some of the 24awg turnigy wire in with the battery?
It should fit in one of the creases pretty easily but won’t fit any 18650 tube I know of after that.
And while we’re on the subject, I suspect that this modification is unnecessary: these batteries are “case negative” and have a positive pole in the center at one end. Presumably the goal of putting the 24AWG wire in place would be to get both positive and negative at one end. If a person was willing to modify the cell in order to do that then all they need to do is remove some of the heatshrink at the positive end.
Unless your using protected batteries. Taking negative from the case will bypass the protection.
My goal is to replicate this, but with better cells
You want thin wire strips for that. That tmart pack would be using them. Its also the same as is used for the protection circuit.

Unless your flashlight has room for thick wires running alongside the batteries.
Strange thing to want IMO & I don’t see why the wire is required. A thin foil strip would normally be used to bring B+ back to the protection circuit. Do you have a source for an appropriate 2s protection circuit w/ balancing?
How will you charge it?
That tmart pack is Parallel.
Thanks halo. Is there anything in particular I’m looking for in those strips?
