I discovered this after trying 4 different sets of batteries in a remote only to realise my new phone didn't show the IR light. :facepalm: Ed, you look at the diode. The duration of the light output is typically slower than the speed of light. ;) | |

Resistance shouldn't be an issue on such a short cable, assuming you've not wired it in something much smaller than the original cable. Volt drops normally only occur on really long cable runs. quote: Tried this on a Siemens ultrasonic hand held programmer, it showed up on an old smartphone but not on my iPhone 5s..... odd [Edited on 20-10-2014 by Bart] | |

BTW Steve, are you using shielded wire? If not, you should :D | |

IR beams show up on phone cameras don't they? That would show if its firing at all I guess? | |

Nope, the resistance thing has been mentioned to me today aswell, so will try some thicker wire later. quote: | |

The wire you are using might have quite a high natural resistance.. or maybe your soldering sucks? Have you tried testing the impedance with a meter? | |

Yeah, but they aren't really part of the equation as the problem happens even with no detectors on the ends of the wire. | |

You did wire up the IR LED's around EXACTLY the same way you removed them yes? :D | |

Basically I have a couple of lasertag guns, they have 3 what I believe are IR sensors on them to detect the hits, what Im trying to do is extend the sensors away from the gun. |
