Default Presenting "Supersound Photography" :)

In its early stages as with many of my inventions
The main principle is that, using a camera with a ccd sensor [D50], as I press the shutter release and the camera takes the picture the flash circuit switches an SCR which dumps 240 volts from a capacitor that has been charged by an old flash - through a wire which explodes - then the sound waves travel to a modified voice activated switch which triggers the flash .... all within 1/4000th sec
Now I need to get creative - I think I can tame the light by putting a large water balloon on top of the wire and then using the flash to light the top of the water balloon....

The first photos are messy - but this is just the beginning

Today's test results. I set shutter speed to 1/250th to allow for some leeway in the distance I have the microphone. F36 to control the light of the exploding wire , iso200. I moved the mic 64cm away which would take the sound 1/500th sec to reach it and trigger the first flash, which triggers the second flash optically. Initially I had the mic much closer, it is now 10X further away but the balloon still doesn't have enough time to burst before the flash fires.

Thanks, at the moment I have some obstacles to overcome but I will get there eventually
