to control the voltage to the 55 circuit you would need a micro Vreg ! they make them VARY small ! they are linear however but at such small currents it would work .
Using PWM instead of Variable Voltage?

The 555 circuit I built required no regulator... it reduced power to the atty by decreasing the percentage of time power was going to the atty.
If the 555 was in the "on" state 90% of the time... 90% of the power was delivered to the atty... At 50% on state, 50% power... the unloaded voltage held at the battery voltage, under load it pulled down a bit... but the real regulation happening here is due to it being off for a portion of the duty cycle.
Hi Breaktru! Love your work!
One of the things I liked about using a very low-power 555 (like the TS555) was that with 10pA current on the reset input, you could use that as a touch-switch, and get double the bang for your buck. That being said, a simple PWM circuit really is the "poor-man's" solution; the switching regulator you found really is elegant, and I'll almost surely wind up shelling out for a few of these before I'm done...
By the way, how did you figure out about the extra resistor to get lower than 5V from the PTN0405c? (Haven't seen that in any of their app guides...) What's the switching IC they use? And is there a way to get broader V ranges than those listed in your original post?
Ahhhh twg, that my friend is a secret. Read about it in my Patent.
I have to give credit to several modders here on the ECF for the inspiration I got from their mods that led me to build:
a simple 3.7v copper mod, the V.V. copper mod (7.4v), the V.V. booster copper mod w/ digial pot and the .44 mini V.V. booster box mod.
Soon to be made: 7.4v, side by side copper mod w/ PTN08100w and who knows what else I can stick in there. Hey maybe I'll steal your PWM and make it touch too.
Can't remember everyone who helped, but I'll try: Thank You BigBlue30, WillyB, Parallexl2, TuErOs, asdaq, Gummy bear, Scubabatdan, I know there where more. Sorry if I left you out.

Yea like all my patent pending "Gummy Tanks" that MAP sells.
However with you just giving credit to about 7 of us modders here for your patent, I think that a small 10% royality would work just fine. That would still leave you with 30%.
You mean Zen-Tanks, don't you? I made mine first, just never disclosed it...
Gummy put a fill screw, so it's technically different. I put a left hand screw so mine is different too. That's 3 patents for the same but different tanks
And my V.V. patent goes from high to low voltage. The patent for the other guy is for low to high

brilliant!
And in the end it doesn't matter one bit because BadKolo will take credit for it.
You guys crack me up. I'd say you all deserve patents .....Just try and cash in on them with all this stuff from China being imported...
@twgbonehead how did you say you would get a regulated voltage? Constant-Power in post #18 = consistent PWMed voltage? The battery has a performance curve, so just having a fixed % duty-cycle, it will still vary according to that curve. Now, maybe you could use a comparator of some sort with a reference voltage... of course then you would be building your own switching regulator!

And Willy B says that if we search for it first, we will find the answer without even knowing the question!
I know gummies are short... but that's way below the belt! (I haven't been following the modder's forum enough)
@ Atty,
It was an inside joke. Bad takes credit for all of BR5495's work, keeps him in a dark basement workshop, only feeds him Cheetos,,

Poor BR5495..........we should break him out. Is this thread off track, or is it just me?
Yea I do that sometimes, Sorry for the derail. Just keeping it light, laughter is the best meds. and VV is the best mods.
oh thank you, I shall give you an Indian name for all of your contributions to that end.
From now on I shall call you "Conotocaurious".
