Just thought I would share this odd thing what happened to me yesterday as I was going to bed.
I have a set of 80 LED Christmas lights hanging up around my bedroom and last night I noticed that a few of the lights (think the blue ones) towards the end of the chain very faintly flickered when I turned by bed side fan on.
Note the set of LED lights is not plugged in (physically unplugged), although the excess cable for the set is rapped up in a bundle amongst all my cables behind my computer. Also my bedroom was pitch black when I saw the flicker of light and I had been in the dark for a few minute.
Further more, the power strip that feeds my computer/monitors,etc... was switched of when I noticed the odd effect and that I have also all ready ruled out any possibility of any reflection from my fan in case of internal sparking from the fan.
Also out of curiosity, I have measured voltage at the 3 pin connector between the positive pin and the negative pin for the red/blue section (See photo below); and when I switch my fan on, out the reading on my DMM peaks at 3-6 mV.
My best guess of the cause is simply a tiny bit current is being induced through EM induction in the LED light set either from the area blow my desk with all my electrical cables or via the cables above the ceiling which below is the end of the LED light set where I noticed the flicker.
I tried filming what I saw in person but I did not see anything on the built in playback, will go over the footage in the next few days.
Anyone got any other theories?
