Single Status Update
Triggerfish shows us two photos of his simple and ingenious trigger. The parts list is:
T6 LED, two, available as CREE XML T6 on eBay. Mouser Electronics and similar may also sell them, but eBay is cheaper.
23A-12V battery, the Duracell 21/23 model may be the best.
TIP-22 transistor from Mouser or Digikey electronics.
Roer RS black part shown in photo may be a Roer RockerSwitch, need clarification.
Connector, need suggestion.
Board and mount for the LEDs and components.
Please make suggestions, additions and corrections to the above.
Let us hope another knowledgeable Wetpixeler will design and publish a TTL board.
