    Singing Tesla coils...?

    Has anyone built them? I am getting involved in an engineering organization here at the university and might be interested in building a couple. Any suggestions? Examples? Directions? Websites?

    oops, this should be in the renewable energy forum. My bad

    Trust your own instinct. Your mistakes might as well be your own, instead of someone else's ~BW~ It's kind of fun to do the impossible ~WD~ From now on, I'll connect the dots my own way ~BW~ If I shall be like him, who shall be like me? ~LR~ Had I not created my whole world, I would certainly have died in other people’s ~AN~

    bump for good measure

      This type?

      I think this is your cheapest option... or one of:

        Yep those be the ones. Musical Tesla Coils

        Anyone had much experience building SSTC's?

          Heck, i'm nearly off to bed and just caught your post, but yes
          More info tomorrow if it's interesting for ya.

          Mine are simple but solid enough Slayer Exciters, running from 7.5V to 12V from a wall adapter (100ma or so input current) and using a 'Walgreen' Tesla tower of own design. The tower is made from one of the small sized pills bottles, from Walgreens or Walmart and wound with about 800 turns of about 36 gauge wire, taken from old DC motors. The cheapest and most plentiful source of which are cassette radio/home CD player motors, Mabuchi RF-300's. Using such motor wire, you need 8 different lots from the stators, so 3 motors worth.
          Apart from the time to wind the tower, everything is pretty straight forward. The Slayer circuit is within the huge JonnyDavro Joule Thief exciter circuits thread.
          Audio input is from the headphones jack of the PC speakers. One wire to Ground, one to the Base of the transistor, adjust volume for best clarity from the plasma.
          The primary coil fits inside the tower. A couple of turns of 'bell wire/speaker hook up' wire about 18gauge will normally suffice for a Walgreen on 12V to create plasma.
          Audio output is admittedly tinny sounding, but the whole thing is only a couple of inches tall

          Here's one vid of mine, showing the Walgreen in action.
          Voltage and transistor - 7.5V and a PNP B647A

          The house bulb is being powered by the wireless electricity, for the sound to light. The blue LED is on a 12 turn coil and 4x 1N4148's for a wireless field tester (normally) and here giving erm stage lighting. The tip of the pencil shows that the plasma is indeed coming from the plasma output of the coil.
          The polystyrene cups form an attempt at enhancement of the plasma audio.

            Can ELECTRICITY pass through Flash light of the Digital camera to your body??? Yes it

            Hi
            this seems to be an off topic but a warning to all

            Can ELECTRICITY pass through Flash light of the Digital camera to your body??? Yes it is 100% true..!

            This is a true incidence reported of a boy aged 19, who was studying in 1st year of engineering, who died in Keshvani Hospital, Mumbai. He was admitted in the Hospital as a burned patient. Reason ??????

            This boy had gone to Amravati (a place located in State of Maharashtra ) on a study tour, on their return they were waiting at the railway station to catch the train. Many of them started taking pictures of their friends using "Mobile Phones" and / or "Digital Camera". One of them complained that, he was unable to capture the full group of friends in one frame in the Digicam.
            This boy moved away to a distance to get the whole group.

            He failed to notice that at an angle above his head, 40,000 volts electrical line was passing through.
            As soon as he clicked the digital camera? 40,000 volt current passed through the camera flash light to his camera and then from his camera to his fingers & to his body. All this happened within a fraction of a second. His body was half burned.
            They arranged for an ambulance & his burned body was brought to Keshavani Hospital, Mumbai.

            For one & half days or so he was conscious & talking. Doctors did not have much hopes as there was a lot of complex issues in his body. He passed away later.
            Now how many of us are aware about these technical threats & dangers? Even if we are, how many of us are adhering??
