Are you tired of those old black speakers that only just make sounds? Maybe sound reactive lights are just not enough to impress you? How about a Plasma Speaker?
A plasma speaker is a device that generates an high voltage electrical arc that makes purple light and music! Without any speakers or any moving parts! Sounds too good to be true? Well, you're wrong, the high voltage arc really does 'sing' by vibrating in the air. (Of course, you will need to give the device musical audio for it to work.) And just leave this instructable if you still don't believe me...
And this is something I always wanted to build - I have been dreaming to build one for about 6 months, until Kiteman has greatly boosted my encouragement to build one. (Thanks Kiteman!)
Health Hazard Unlike the ordinary speakers, the plasma speaker are dangerous high voltage device, do NOT attempt to build this device unless you know what you are doing... And do NOT even attempt to build one if you have heart problems or weak heart or wearing a pacemaker, because one little shock from this thing can put you out... I am not responsible for any injuries or deaths caused by this device.
Why should you know all of this? it is because you can ONLY live once, and no more... If you don't think that you shouldn't build one, just watch movies of it working instead, much better than risking your life to build and operate one. If you think you are okay to build one without killing your self, then move on to the next step.
Hazard to Electronics Since the plasma speaker generates high voltages, there is a chance there will be high voltage spikes on the low voltage side of the device, which can get onto the audio line and damage (or destroy) the player. They are some safety features to prevent the spikes damaging the player, but they can fail... So I am not responsible if your player gets damaged, and use cheap players like CD players, if you're rich, you can use expensive players if you want. :-)
