Yes, I've considered this. The question is whether it can be specified to rotate freely + have stops at specified intervals such as every 45 degrees. Any advice on good suppliers where something like this could be sourced would be appreciated.

Does anyone know if the following is available as an off-the-shelf component and what would it be called? One-way rotation mechanism Has detents or stops at specified intervals (such as every 90 degrees) Fairly small - for attaching an approximately 2" diameter wheel or circular disc to Doesn't...

Actually, the primary concern is if people are inside of the shielded room. It seems it will be ok if properly designed.

I need to read that article. Interesting that thickness of shield material apparently does not matter, it is the continuity of the enclosure that determines leakage. Therefore, absorptive materials on the inside should prevent any leaked frequencies from continuously reflecting back + forth on...

What I meant to say was if the power level was high enough to penetrate the shielding material itself, not just leaking through holes. In this case could it create conditions inside the cage that would exceed the ability of absorptive materials to reduce the frequencies?

I have to review the study you've referenced. I agree about the dissipative element being capable of absorbing penetration due to small leaks, but what about if of the power level of the frequency was high enough to result in a lot of frequency penetrating to the interior, where it can bounce...

If inside of a metal (for ex. Aluminum) enclosure, could it potentially create more harm than good if frequencies were able to penetrate due to an imperfectly sealed cage or due to a relatively high power level of frequencies that allowed them to penetrate the metal? If the power level was high...

Another option is getting a modem that does not have Wifi, but the simplest solution may be the Faraday cage - I just didn't know if such a cage would shield the majority of the signal.

Does anyone know how to locate the wifi transmitter on a modem circuit board, is it the "Radio Transceiver"? Once located, is it possible to remove it or disable it. Wifi is enabled on my modem, and disabling it via software doesn't work.

The two input wires are just regular insulated 22 gauge wire; they aren't lamp cord with a rib, so I can't differentiate them. I definitely need to identify which one is the neutral so that it can be connected to the correct prong on the plug? Or is it possible that it doesn't matter which...

Jim, I'll do the tests with the meter. Will the results of the tests also tell me if the two input wires are specific to a particular prong on the two-prong plug? The case is plastic. Thanks to everyone.

The shock hazard, I think, refers to the black output wire labeled as Ground. This wire seems to be for optional attachment to a dust collection plate which is used to collect the negative ions generated by plate attached to the 10kV output. Electrons from the statically charged negative plate...

When I wired the 2 input wires to a 2-prong plug, I questioned if each wire went to a specific prong on the plug, but the supplier I bought it from claimed it didn't matter. I have a circuit diagram that was emailed to me by Yuida compay, but it is a .doc file and I couldn't upload it to the...

Dr. Zoidberg, You were right about insulating the output. I wrapped plastic around the output wire where it was connected to an 18 gauge extension wire by a wire nut. I had electrical tape around the wire nut, but I think high voltage charge was leaking out at this spot because I could...

Do you mean insulate the output end of the device itself or the entire length of the output wire (which is insulated 18 gauge copper wire leading to the plate). I'll use a heat sink. Thanks, Matt
