Basic Triggr Personality

Ok here is the 1st basic trigger personality board.

Features:

  • x4 LEDs for visual indication.
  • x2 Push Button Switches, one tied to input for manual triggering/testing, the second independent, could be used for channel or function selection, both could used in conjunction with LEDS for advanced function selection.
  • 1 Strobe output. 400V Max (so will work with older type strobes)
  • 1 protected TTL trigger input. 
  • Small prototype area.
  • Low profile, All large components are mounted underneath.

Still a little cleaning up required but basic functionality is there.

Still TO DO:

  • Change MOC3023 to SMD footprint, I don’t really want the possibility of a large strobe voltage right where a thumb might be.

Tests

Here’s are some initial non scientific test results of the prototype.

Sidenote: I had some fun testing these outside at night, everytime a car drove past I triggered the strobe, instant brake lights, hehe (The use of speed cameras are notorious here in Western Australia).

The Unit, both the master and slave are identical, personality is determined at powerup by pressing the trigger button if you want a master.
