Flyback plasma speaker with 555

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

Well done on getting this working.
A question though, what is D5 there for?
Also, do you need to take into account that most LOPTs these days have a rectifier in its output? Will it work regardless?

[Glenn781]

I was haveing major heating so I popped d5 in there and it droped the some of the heat it may not be needed but every bit helps. As for the built in rectifer its on the output you wanna stop emf spikes from passing to the input coil witch will heat up your transistor. Let me know how it turns out!!! If you have any problems let me know im here to help!

oh god no

hey nice instructable
can i have a proper type of circuit diagram please
i cant understnd this !
thanks
akinich

[Glenn781]

Tish is a proper ciruit diagram if you click the I on the upper left if the ciruit it will let you see the full size image thanx for your commet if you need any more help plz let me know

[akinich]

i know tht but i kinda want a simpler one like n revheads instructablle the laser securtiy thing
if its possible please ????
thanks
akinich

[Glenn781]

Im sorry if you cant understand this ciruit plz do not attempt to make it I dont want you getting hurt!!!!

Love the fact that this uses a 555, very cheap. Would like to see more discussion on you schematic though if that is possible. Maybe upload a more clear image.

click on the "i" in the corner then click on see original image. Instructables over compressed a very clear image.

Can you replace all by a broken plasma globe?

[Glenn781]

not shure you should try

[joemilliken]

Good job, seems very simple compared to others I've seen.
