Cool idea. I never heard of them. Thanks. ---Carl-----Original Message----- From: Carl Bradley

It will not inhibit the action---just prevent injury.

I doubt that plastic wrap would stop shards of glass from causing a wound. And they will wave it around despite what you tell them. I would 'guesstimate' the weight of the resonant circuit and put the samemass on the end of a tube and try it yourself (attired with requisite safetyapparel).Besides, where is your voltage gradient? Your resonant circuit will have twopoles. Are you planning to run a shielded line down the tube and connect it to the other end of the tube?

However the idea I need advice on is taking a couple hundred feet of copper magnet wire like the kind you wind on a secondary, and coiling it up onto a form that sits at one end of a fluorescent tube. Add a tuning capacitor in parallel to make a tank circuit and using that as an antenna to extend the range of the wireless light effect. It's like a crystal radio circuit but it is there to only receive power and no signal. The winding and capacitor would be visible and part of the cool retro look. Any thoughts on that?
