Hi, this is Wayne again with a topic “Plasma Arc Speaker”.
The plasma arc speaker by John iodine is a high-voltage project that is equally cool to see as it is to here. Unlike a conventional speaker, which vibrates the solid diaphragm to create sound, this speaker oscillates highly ionized plasma gas from an electric arc to create sound, solid vibrating diaphragms are affected by their own mass, but the gaseous diaphragm of the arch speaker is virtually massless, making it extremely Adept at reproducing high frequencies, in fact some very high-end speakers, utilize plasma tweeters to create their high fidelity high frequency, sound, this speaker featured in Make Magazine vol 44 is easily sourced, where it can be ordered as a kit building. It requires only basic Electronics experience, but just like a Tesla coil or any other high voltage project, it’s important to follow safety precautions when building this speaker check out, make zine comm for complete safety information to build this circuit solder, the components to the PCB supplied in The kit or you can prototype the circuit with point-to-point wiring, a 5×5 timer chip creates a frequency modulated version of the audio input which is amplified by the high voltage transformer which drives the electric arc to sync. This circuit uses high voltage and also gets quite hot for safety.
This project should be mounted in a project enclosure. It will definitely need a heatsink and fan to fabricate the plasma tube, make three cuts and drill two holes in a piece of 3-inch, clear plastic tubing. This will house the plasma art solder, a length of 22 gauge wire to each of the binding posts terminals and then install them in the tube next you’ll attach the high-voltage wires from the transformer to these terminals, set the trim potentiometer to its centre position and you’re.
Almost there, the last thing to do is adjust the electrodes arrange the wire so that the wire ends face each other. If the arc jumps from the side of the wire you’ll hear Distortion. Finally, adjust the gap to about 1/4 inch and you’re, ready to rock out hit play power on the speaker and enjoy some electric tunes check out, mixing com for more projects and to share your own bill.
