Tesla coil , a set on Flickr.
A while ago i was asked to make a Tesla Coil for an exhibition about Nikola Tesla. I have previously experimented with traditional Tesla coils (Archive). These were loud, dangerous and not really public friendly devices.
A new generation of electronically controlled solid state Tesla coils have been emerging over the last couple of years and we decided that one of these were better suited for public display.
A side effect of the electronic control is the ability to play music. I find this feature rather corny but it seems to be a real crowd pleaser.
Here are the result of the first build night with my long-time Tesla buddy Marc.
