Watch out how many xmas lights you put up

Might affect your wifi signal

Sweet jebus, been meaning to take apart a string of LED xmas lights to see what makes them tick. Think I might make that a higher priority. Wondering if they're putting the AC out of phase or something really dirty.
-
@MattSpeller kinda doubt that LED's qualify in this example... but don't let that stop ya
-
@art_of_shred I can't think of a reason the incandescent ones would bother anything unless you wrap them around the router to create an electromagnet or blanket your walls with them to make a Faraday cage.
-
@MattSpeller I was simply thinking that whatever effect, if any, would be far less from a 2V LED than a 110V string of incandescent bulbs.
-
My wife is good at this stuff.
-
@art_of_shred It's actually less the LED's and more how they rectify and transform the 120v from your wall to the low voltage DC the LED's want

@brianlittlejohn Nicely found Sir.
Looks like they run them on AC! Which is a bit wackadoo crazy but it seems to work. You could test this by plugging in a strand and spinning it around in the air like a lasso, you should see them pulsing on and off.

It actually kinda makes sense, What is an AC to DC adapter? In simple terms it is a transformer, diode, and capacitor. The LEDs are diodes (all be it more sensitive).
-
@brianlittlejohn yeah I hadn't thought to just string them all together in series to build a kind of... half bridge rectifier? Neat circuit actually.
-
@brianlittlejohn Still don't know how it would affect your WIFI though lol

That I don't know either.

Same way ballists in fluorescent lights do. Magic.
-
The LED ones, will likely not as they are DC.

Ballasts do because they are big Inductors to control the flow of electricity.

Yup and even then the effect drops with the square of the distance so it's a very localized disturbance.

Why would either?
Well, mostly because traditional, non-LED, models use incandescent bulbs. Bulbs, which I thought were noisier EMI wise than other things. But I could always be wrong. I never actually studied it.
