Lol I’ll be adding a resistor, but they’re not as bright in person, the camera makes them a bit brighter.Those are bright as heck, will you be reducing the brightness or are your eyes immune to searing?
You're using one resistor per LED?Need help, my 4th led keeps burning out even with resistor, I have soldered led to a 120ohm resistor and to 3.85v from joycon.
leds
1-input 3.85v- 120ohm resistor- output 2.24v
2-input 3.85v- 120ohm resistor- output 2.24v
3-input 3.85v- 120ohm resistor- output 2.24v
4-input 3.85v- 120ohm resistor- output 2.5v
Any help would be great I already tried a higher ohm resistor with no luck.
I see that your powering your LEDs from an external source; My guess is that your external source is causing the burnout or there's something you're missing in your calculation.Yes that’s what it said on a online resistor calculator
I’m powering the leds from joycon battery, but I just checked on another resistor calculator and it says to use a 12ohm resistor, it’s just the red leds I hate using these even on my psps.

I did this same mod recently as you can see here:
Looks like we're using the same LEDs, so I can say with confidence that it's probably your power source. These LEDs should be able to handle the voltage output from the joycons.
Another video which helped (but had some inaccurate info):
The bluetooth status is not 1.8 volts but rather 0.56 volts.
I'd bump it up to ~100ohms; Never hurts to start higher and go lower just to get the brightness you want.I’m powering the leds from joycon battery, but I just checked on another resistor calculator and it says to use a 12ohm resistor, it’s just the red leds I hate using these even on my psps.

I had 120ohms each led and 1 led always burnt out, I calculated a resistor for wiring in parallel and it says 12ohms for all of them, also right now I have them with a 300ohm resistor each and it works fine ran them for 3 hours and they all work.I'd bump it up to ~100ohms; Never hurts to start higher and go lower just to get the brightness you want.
Are you sure that's not 12 ohms for all of them in series? Do you have a schematic or a picture of the current setup?I had 120ohms each led and 1 led always burnt out, I calculated a resistor for wiring in parallel and it says 12ohms for all of them, also right now I have them with a 300ohm resistor each and it works fine ran them for 3 hours and they all work.
That’s what it showed in parallel, and this is all I have at the moment I’m at work.Are you sure that's not 12 ohms for all of them in series? Do you have a schematic or a picture of the current setup?
I just deleted my other reply since I realized the calculator on that website was giving me wrong information. In the parallel mode it automatically puts multiple LEDs on one resistor, which you don't want to do. In the other mode it automatically puts some LEDs in series and others in parallel, which is also not something that's desired.I’m using 0603 red smd leds, I’ve always used 20ma to calculate and they’ve always work until now with joycons,
so do you think it’s better to use 1 resistor per led?
If it's working now then I wouldn't mess with itThanks for all the help, in the last pic I uploaded I’m using 120ohms per led and my 4th led still went out, right now I have it wired with a 300ohm and it works fine, do you think I should use a 180ohm or leave it how it is?
That makes sense then. You could probably also do 180 ohm but it would just be way brighter. If you like the brightness it's at, keep the 300 ohm.Thanks I want to finish these because I got some other ones to do lol, I got these leds on amazon and on the label it said 2-2.2v 20ma
Yea I’ll keep them how they are for now, thank you so much for the info and all the help I appreciate it.That makes sense then. You could probably also do 180 ohm but it would just be way brighter. If you like the brightness it's at, keep the 300 ohm.
