Yes your wrong about the relay..Not about a static air spark gap but thats not what were doing. Relay's  will operate on low voltage its the speed they operate at that will affect the freq of the output in the secondary. anyways i have a little relay i built here like shown in hans's diagram and changed a little and it works off of 1.5 v aa nice and fast with a a cool little blue spark 

The insulation eg mica ceulloid for the secondary is real insulation so the wire isnt exposed. Plastic insulation or litz should do fine nylon is a plastic ..  Mabey some other covering over the whole shebang once done 

I dont think the beer cans have anything to do with this self generating induction coil i think they are part of the wireless transmitter setup
                                                                                                        Hope that helps

O K excellent

Is that the nonmetallic contact?

Could you go into some detail about the nonmetallic contact? I see copper and a metal screw in your drawing, yet it says non-metallic contact.

Thanks

I just went to wiki on electronic relay.
I do not have the answer but I see that I keep asking the same question.

I will try to study up a bit and not bother with these questions.

But

If someone could point the way for an easy to build relay so I can do it and watch it, I will try it before continuing.

Maybe Hans already did?

Joe, is yours an easy design? I have a tiny bit of experience building circuits - just lots of holes in experience and understanding esp AC.

thank you,

@ Jeanna:

I'll try to help.  First, look at Joe's drawing. (I am going from memory here as you can't see drawings while posting)  What you have is a connection being made between the copper and the iron wire via a flexible conducting material. When that connection is made, it turns the primary into an electromagnet which then draws the flexible metal strip back down toward it which then breaks the copper/iron wire connection which allows the strip to go back and make the connection again, and so on.  Very similar to the bell picture I posted a while back.  Same principal.  Joe's design is exactly like Hans's except that it does not use and external battery or coil other than the one we built for the primary.

Also, as Joe said, this design is very dependent upon the coil configuration (wire dia. length, number of layers, etc.) to determine the frequency at which the make/brake takes place.  The rotary design allows for more variance in this area.  I hope this helps.  (Edit:  it is a non-magnetic contact, not non-metallic)

@ Joe:

How do you plan on starting the make/break cycle?  Moving the metal strip with your finger?  A switch to close the circuit initially?  Jeanna raised this question to me and I was not really sure.  I can see how it could be done, but did not know what you were planning. Thanks.
