--- Quote from: StillTrying on October 26, 2018, 12:18:40 am ---10ns pulses and 3ns latency will just be noise, real light pulses will be 10X slower than that. --- End quote --- Wow, must be pretty magic because i can repeatibly put a bit of paper between the emitter and the detector and remove the signal without changing any other bit of the set up....... :-DD |

Color me impressed. :-+ Would you mind posting a schematic of your circuit? |

I'll grab some scope traces if i get a chance this weekend! :-+ |

I hope I'm wrong, but I think your 10ns-wide 3ns-delayed received pulses are just noise from the switching-on edge of the emitter, many of my captures show it. |
