I made a nice 2ohm coil for my odysseus and it's been vaping great, so great I though I'd take it to work with me, There I was sitting at my workstation happily vaping away when I noticed that every time I took a toke it interfered with the DAB radio signal and the music stopped, much to my collegues dismay ![:o](//storage.proboards.com/2973975/images/V_yPuiwBICIqOziN7BjO.gif) They threatened to insert my odysseus somewhere that would make my eyes water - nasty men ![;D](//storage.proboards.com/2973975/images/uKg77DgrQpkBFJJN7U0P.gif) It got me thinking though, I had no problem vaping anywhere, thinking that I wasn't having any adverse effects on anybody or anything and it turns out that we really need to be careful where we use our e-cigs. When we're told that we can't vape on a plane or in a hospital it's worth remembering that electrical appliances that use resistance can affect other electrical equipment and we should be a bit more understanding. I know these places have protection circuits and filters to guard against such things but still...........

What e-cig were you using Blakey?
I can understand the VV circuitry affecting electronics as it "steps up" or down the battery voltage supplied to the coil.

I suspected it was a VV device, if you want to experiment you may find that different devices cause different levels of interference. If it's just a straight battery switch like a screwdriver it probably will not affect anything.

VV devices use a DC to DC converter to step up the battery, the coil may then act as an antenna.

Really? cos my don with it's maual switch and single battery has just had the same effect on the DAB radio at home using a bulli.

Oh did it?, well I'm flummoxed then, you need to have a AC field to transmit a radio frequency............... Maybe someone else will comment? Perhaps it's a magnetic field?, might be due to the Solar mass ejection that is causing the Northern lights at the moment!

I had to try this.
Lavatube right next to DAB radio, did the same as Blakey, knocked it off for a couple of seconds.
But 6 feet away it was fine. No reaction with the Riva.

Ahhh wait there is current stabilising electronics an many devices... also it MAY depend if the electronics are shielded by the body of the device. RF can do weird things.

Just tried my LT next to my Roberts DAB and if I hold it very near to the ariel base it knocks out the signal. No affect on a FM radio though.
If the signal is relatively weak I suspect that the effect will be more pronounced.

Any coil with with an electrical current will produce a electro-magnetic field. It's unlikely that a a coil the size of an atomiser would create a large enough field to de-modulate an fm or digital radio wave even if it's just inches away. It certainly would'nt interfere with the VHF spectrum used in aircraft. However, loudspeakers are quite susceptible, if in very close proximity as they operate (to an extent) with a magnet which works in tandem with the voice coil. The voice coil vibrates to create the pressure changes we often hear as the drivel that is Rap & Westlife etc etc.

What a very interesting thread ![:)](//storage.proboards.com/forum/images/smiley/smiley.png) This is something that I also was completely ignorant about.

Bloody hell. I just tried this with my DAB radio. With the Lavatube it goes off from about a foot away from the aerial. Actually puffing it gives a bigger efffect rather than just switching it on. Also, turning it through 90 degrees changes the effect. I can't get any effect though from a Riva type battery, a box mod or a battery mod. I also tried it on FM and it just caused some interference rather than a complete loss of signal as with DAB.

Never crossed my mind either.
I now have this image in my head of vapers conducting experiments at home all evening all over the country!

I have a Roberts DAB radio running on batteries and have foud: Standard Riva - no interference Ego/Riva VV - tried at 3.2v, 3.7v & 4.2v - no interfereance Ego/Riva 18650 - No interference Lavatube - at 3v a little interfereance BUT when I take a "pull" it interferes worse! had to hold near at 3v but standing At 3.7v knock out signal when held near BUT when I stand 4 feet away and toke it interferes like mad! Anything over 3.7v even sat down 4 feet away it knock out the radio! ![:o](//storage.proboards.com/2973975/images/V_yPuiwBICIqOziN7BjO.gif)
