    k,

    All callipers are 1.5v.
    Maybe I have some wack LEDs, don't think I've measured less than 1.7v across the one in the power section and that was with >1k resistor, not good for maintaining voltage stability at those values. I thing the vf of my reds is around 2v

    Try a couple of forward biased silicon diodes (e.g. 1n4148, or even 1n4000 series would do), they should give you about 0.7v each .
