so i thought i would set out to make a plasma speaker! SO one chip i know well is a LM555 so this is my base! one pin most often skiped on this chip is pin5 it s the voltage control oscillator. all that is needed is an audio signal to this pin to get pwm

Step 1: Parts List

99% of the parts can be obtained from http://www.allelectronics.com/

1 3.5MM MONO OPEN AUDIO PHONE JACK

1 SPDT ON-ON MINI TOGGLE SWITCH

2 9V BATTERY SNAP, I-TYPE

1 Heatsink

1 Lm555

1 8pin socket for the 555

2 20k pots

1 10k trim pot

1 100ohm pot

2 1n4148 diode

2 1k 1/2 watt risistor

1 ADJ. POS. REG.

1 2n3055

1 .001uf cap

1 .03uf cap

1 Gi2404 diode

othere parts needed

2 9v batteries

1 16v 3 amp DC power supply

1 FLYBACK TRANSFORMER

1 audio signal you may need some type of amplifier if you use a weak signal like a cell phone or weak mp3(im using an old raidoshack amp)

Step 2: Schematic

note the batts ground and the power supply ground are hooked together

Step 3: Heatsinking

mount 2n3055 and gi2404 diode to a large heat sink

Step 4: Find the Flyback Pin Outs

this set shows you how to find you flybacks pin outs

Step 5: Last Chance to Rechk Everything

ok so now that your allset start with the 0v and hv out about 1/4inch apart then slow move back till you get a longer soft spark if it go wild move it closer
