This is the result of my latest experimentation, a high-quality low distortion transformer plasma arc speaker ("singing arc"). A PWM audio modulation circuit (TL494) runs at 40kHz, drives two mosfets in phase in a "half-controlled fullbridge" fashion (two switch single pulse forward-flyback converter). A RC damping network on the primary gets rid of unwanted oscillations during the free-wheeling phase. As always, the camera distorts the sound a bit and cuts treble, it sounds cleaner in real life.

English & Español description : I was asked to make this Plasma Speaker, for a demonstration on the popular Spanish TV programme, 'El Hormiguero' - Episode 164 - 4th June 2008.

The female guest, is singer Julieta Venegas (Grammy & MTV music awards winner) - it is one of her tracks, that is used in the demo. Best watched in Full Screen High Quality mode ;) If not shown as an option, add 'fmt=18' to the end of the URL. Me pidieron hacer este altavoz del plasma, para una demostración en el programa popular del español TV, ' EL Hormiguero' - Episodio 164 - 4 de junio de 2008. Pablo & Flipy (el científico) hace un gran trabajo, con ayuda de su ayudante - aunque habrían podido tenerla el jugar de un pedacito más ruidosamente en el estudio... La huésped femenina, es cantante Julieta Venegas (& de Grammy; La música de MTV concede al ganador) - es una de sus pistas, de que se utiliza en la versión parcial de programa. Mejor mirado en modo de plena pantalla de la alta calidad ;)
