So… I read a few things about how to make a diy jack with a led and decided to give a try. Turns out it’s neat and fun, also really easy to make!

 

Parts used

Bipolar/Bicolor leds from aliexpress (beware, don’t get the blinking ones if you order somewhere else)

Apparently they list them as 3mm… they are indeed the ones i used…

I think theses would work too.

 

Then resistors:

470 ohm resistor or about the same value will work. I used the smaller resistors because it’s way easier to fit it inside. It depends on your led, i like them bright but not too much, some use 1k instead. You can calculate here : http://led.linear1.org/1led.wiz

I use theses 3.5mm plugs https://fr.aliexpress.com/item/Free-shipping3-5mm-plug-RCA-Audio-Connector-RCA-audio-plug-3-5mm-jack-mono-Headphone-10pcs/32537455887.html

You basicly just need to solder the led on the resistor and jack, then i added some heatshrink 6mm but it’s not really needed. There’s too much solder in there but it was the first i made, practice makes perfect!
