Arduinoses and High Speed Photography.

Howdee y'all,
  I ventured up to the DIY High Speed Photography at the edge earlier
this week. Two sessions running, one with wireless remote triggered
flash, the other with a arduino monitoring a laser pointer on a resistor
to automatically trigger flash on beam break.

  The arduino apparently had a 50msec delay between break and fire. I
had other thoughts, like accelerometer to detect table/bowl hit, or more
simply, a trigger on sound pressure level ;)

  If anyone has a crusty old external flash (but with an intensity
setting) they dont mind lending or selling I'm quite interested. The
flash needs to be variable intensity as you do not get to set shutter
speed during HSP the way it was setup there.

  It's an awesome workshop and folks who held off because of the rain
might enjoy rocking along to a subsequent one.
