Question for the saber guru's....is this possible?

[Jetsi]

Lots of good information in this thread.

Now what is the possibility of doing the opposite, running a momentary board, such as a Hasbro, with a latching switch?

If this was possible, a DPDT latching switch could power the board for sound and the blade with a Lux III/V or K2.

Like the momentary-to-latching trick, this should be a fairly easy job for a cheap and simple microcontroller. Watch an input pin, and remember the last state you saw it in. When its current state is the opposite of its last state -- meaning someone just switched the latch from off to on, or from on to off, send a pulse down the output pin.

I say this in theory, not having tried it yet. I did just get an Arduino starter kit from Adafruit Industries, though, so now I have an incentive to get it set up and start experimenting.
