Walgreen AT – a few more plasma audio tricks !
My Tesla coil speaker. The dinky Walgreen AT Tesla coil speaker now sounds better than ever and is shown here performing a few tricks. Lighting a household bulb for sound to light Wireless LED for a ‘stage’ light Vinyl style scratching with a pencil ! Circuit began as a Slayer exciter (see GBluer’s channel) and now has some filtering for audio work. Transistor this time is a PNP B647A and the circuit is running from a regular wall adapter at 7.5V Of most note to people who are building Slayer circuits – where’s the L1 coil ? 😉
