▲ 68 ▼ What is this wire for? (www.imagenetz.de) submitted 2 years ago by Slow@lemmy.today to c/asklemmy@lemmy.world 18 comments fedilink hide all child comments At one end of the wire is a 3.5 mm Jack plug. On the other end of the wire is presumably a glass LED. When connected to the phone, nothing happens. The LED does not start to glow. Also, this wire doesn't work as a microphone. It's also not an earpiece. What is it for?
[–] breakcore@discuss.tchncs.de 73 points 2 years ago (1 child) It is an infrared receiver extension cord. Say you have a device that is controlled by an infrared remote, but is tucked away out of line of sight. You can use this cord to move the infrared receiver into sight. Here it is on amazon : https://www.amazon.com/uxcell-Infrared-Receiver-Receiving-Distance/dp/B07FKMK3GZ permalink fedilink source hideshow 2 child comments replies: [–] Slow@lemmy.today [S] 5 points 2 years ago (5 children) Can't it be used as a replacement for the infrared port (if the phone doesn't have one)? permalink fedilink source parent hideshow 10 child comments replies: [–] breakcore@discuss.tchncs.de 18 points 2 years ago Typically IR transmitter LEDs are transparent or light blueish, to allow as many photons as possible to exit the LED. Typically IR receiver LEDs are dark, almost black, made to block out visible light and only pass through infrared wavelengths of light. Here you see an IR transmitter LED on top and an IR receiver LED below that. permalink fedilink source parent [–] Kit@lemmy.blahaj.zone 8 points 2 years ago It's a receiver, not a blaster permalink fedilink source parent [–] altima_neo@lemmy.zip 4 points 2 years ago (1 child) No, since your phone only outputs audio through the headphone jack. These required a PC card that used a jack that's wired up to use this. permalink fedilink source parent hideshow 2 child comments replies: [–] Blue_Morpho@lemmy.world 2 points 2 years ago* (last edited 2 years ago) Audio jack ir blaster adapters for phones used to be common. You can still buy them on eBay. Audio is voltage changes which can be set to drive an ir led. You use an app that outputs audio that matches the ir signal protocol. permalink fedilink source parent [–] HurlingDurling@lemmy.world 2 points 2 years ago No, but you can get something like this to do what you are asking https://a.co/d/e6DROYc permalink fedilink source parent [–] Blue_Morpho@lemmy.world 1 point 2 years ago* (last edited 2 years ago) Yes but nowadays you'd buy a USB version since few phones have headphone jacks.
