Thread: Chronographs, what's the story

Close up of the small strip of printed circuit board with the LEDs on it.



Wildman that may be right, it may be possible to have too much light. I vaguely recall that cranking the LEDs up took the sensor circuitry out of it's designed operating range - a bit like trying to get them to work with direct sunlight. The LEDs on this one have a voltage regulator between them and the batteries so the light intensity can be adjusted. Feel free to PM if you like for other details.
