Could pin 5 of the 555 chip be fed an audio signal in order to audio modulate the arc?

[johnb003]

@Alex1M6 I'm gonna have to say yes, since it looks like you were able to replicate the project and actually do just that! ;) nice work btw.

[MrStemkilla]

@Alex1M6 yup! but i subject adding a variable frequency to this by adding a 0-50k potentiometer between pin 6 and 7 using a .01uf cap. its what i use and you can focus the arc vary well. i have a vid up that i use pin 5 to add audio and it works grate you can definitely do it that way i also have it set up to current limit with a transistor not a bank of resisters that works much better. also adding a cap bank to your main input helps alot too in fly back drivers

[Alex1M6]

@MrStemkilla Hi, I actually used two 50k pots and a 1nF cap a while ago and was able to pull near 3 inch arcs with just 12v input! I will send you a link to a video of it running.

What frequency is it oscillating at? If it was a high frequency then the signal might have been beyond the range or frequency response of the speaker and so may have been attenuated by the speaker causing the wierd output that you saw.

Spend some money and bring some 2.1 mm connectors. Dont be so mean that you make your own connectors.

I would like to see the spark current in the CRO!

[johnb003]

@blower05 Me too! but I'd have to do some kind of probing of the current instead of a direct reading because the voltage would fry the oscilloscope. Also I don't have a CRO (assuming you mean cathode ray oscilloscope), although I was thinking about trying to make one with an old CRT monitor.

i liked your input connector.. u made it cheaper then 5cents

The wave form you got is normal. The speaker has a coil and... not enough room to explain but remember coils at 0 time act like an open then after 5 time constants act like a short.

very good video man!

wtf u on abut

 im lost

Preety cool.
