Here’s a clip of the sound-activated fire, with the teensy’s pin 13 LED indicating where it’s clipping my power output to 20W.

Beautiful! That’s exactly what it’s supposed to do, and exactly what it’s supposed to be used for!

Makes battery/power management so much simpler now… just dial-in the wattage or amperage you want to limit to, and bam, done. (Finally.)

Future idea #1: have a ‘soft’ power limit and a ‘hard’ power limit, and allow the animation to go past the soft limit for a short time. Sort of a slow-blow fuse, if you will. So you could say “My power source can deliver 2A continuous, but 3A peak for up to a second…” This would let you more effectively blind people with full-power flashes.

Future idea #2: add a cumulative power-consumption gauge, so you could read out how many milliamp-hours you’d used up so far (and thus estimate how many remained in your battery…).

etc.

But for now, the basic stuff works. Enjoy.
