ARRRRGGGGGGGG:xyxgun:
ok now that i got that out of the way . . .
the initial problem:
multimode driver for 1 li-ion battery and 3 Crees (parellel) run high
the 3+ amp driver from a 3V source doesnt really exist, even though there is stuff that one would believe it does, they all have some huge caveats of some sort.
like the linear regulator, isnt that much better than a resister, it falls out of regulation. (i really dont mind a dwindling output, but i was going for a glorious driver thing this time)
most boost drivers , might be able to handle the low voltage input, but still wont take the AMPS, cause they only use teeney parts :-)
most BOOST only drivers go out of regulation when hit with 4+V from a li-ion, even though they might "work" they arent "working"
most BUCK type drivers want more power or drop out a lot of power along the way, or just dont work in the specific li-ion power range very well.
This was going to be my solution:

(pictures at that link can be expanded, mine has all the same parts in the same places)
this here combo of the linear clipping curcuit, and the boost curcuit, the thing runs GREAT, (better than a graph i saw here) and it worked great with one LED, problem is i still have THREE :nana:.
plus it has all the cool levels and stuff (wowsie wowzer)
so i get 3 of them, one to fry and 2 to combine to attempt to run the 3 leds, mabey run all 3 if i get bold enough.
cut paste assemble assemble (for a long time) and finnaly there it is, 2 of them piled together with a "bump" relay for bumping it to the next level, so they would act as a TEAM. (main mag switch does total disconnect, bump switch runs relay which does a temporary disconnect for mode changes)
La Problema:
They won't Sinc together, i have spent hours bouncing them from mode to mode, trying to get them both in the same mode "Group" (next time its high and low for me :-)
when i finnaly get them sinced in the same group, then i sinc them into the same Mode , and 3 clicks later its off again
ARRRRGGGGGGGG:xyxgun:
What they will do:
the Pair of them teamed up together DO put out the needed current, and do basically time pretty close when they are in the same mode together.
they do pretty much give me the needed boost and clipping for the Driver aspect of it. i just cant Seem to get them to sinc up.
Question #1
Is it possible to sinc up 2-3 multimode drivers (without rewiring), specially when i am using a relay to do the OFF bumping , so there is harsh clean disconnect of the power?
can it be done? i am using a lot of clip leads and stuff now, that could effect the timing. i would like to know if anyone has Synced Multimode drivers and got them to stay sinked.
Question #2
I would far prefer to leave everthing intact, but at this point i have nothing to loose, ( i am about to put a SIMPLE 2 sets of infalable resisters in have 2 modes and be done with it.)
but, if a person could work with tiny little legs on flea sized chips, what leg of the P.I.C would i rip off the board, to jump its output to the other one?
with the intended result being one microcontroller driving both mosfets (i assume) on the 2 seperate boards.
Question #3
if there are any tiny chip mulchers who would like to take a crack at it, i could afford to pay some small sum to have somone who knows what they are doing to collide the boards together , so to work in tandem.
