    Is it possible within a volume of approximately 1 cubic centimeter to have 6 LED's wired to an accelerometer such that when 15+g's of force is detected the LED's will strobe for 1 second? I know circuits like this can be built but can it be done within the space limitations?

    Doesn't have to be an accelerometer... could be an IR/photocell, magnetic, etc...
    Strobing is a nice to have
    Are there rechargeable batteries small enough for this project? Maybe use a capacitor instead?

    Thanks for any help!

    If 1 cubic centimeter is 100x100x100mm then I would have to say yes.

    Including the battery.

    Then I would have to say....no.

    I never bothered to learn the metric system, 10x10x10mm seemed a little small.

    It is small.
    That explains some things.

    So, I got curious and did a quick sizing. It is possible but here's what it takes:
    - all SMD
    - 2 10x10 pcbs
    - components on both sides
    - QFN package or smaller for the processor
    - LGA package for ACC
    - 402 LEDS (dim dim dim)
    - 402 resistors
    - coin cell
    need to use a super small interconnect. 50 mil spacing? need to pass 5 signals (Vcc, gnd, clk, do, di) between boards
