Case #91: Dick worked the graveyard shift:
When the local church needed storm effects for a skit, sound man Dick Neubert found the thunder on the Internet and added "lightning" with a photoflash strobe. He used an uncommitted output from the mixing board to trigger the strobe with the sound signal via a simple interface. The strobe places 300V across SCR1, which discharges this into the trigger coil to fire the tube. In all, this common strobe design will deliver some very uncommon effects for your next Halloween spookfest.
I would love to have a seat watching the reaction of unsuspecting trick or treaters - especially on a foggy Halloween night. The strobe light was a great addition and the bat flying out the door made me jump just watching the video!
Eleven years ago one of those rare, brilliant moments emerged from the crack staff of Design News: Let’s put the tinkerers among our audience community to work in designing and building some truly wacky devices. And Gadget Freak was born.
Followers of Design News’ Gadget Freak blogs will have the opportunity next week to take home a wireless remote demo package that can be used to build garage door openers, tire pressure monitors, keyless entry systems, and much more.
