boost the power of a 9v battery

[jackblack]

im trying to boost the power of a 9v battery these pics r wat i want but dont no what thay r can any one help
thx jackblack
i also have other info on green energy moast interesting reading

First off it doesn't 'boost' the power - it actually reduces it, due to losses.

It's a 'stun gun' and it simply increases the voltage whilst reducing the current.

hope we ned a step up transformer and some components.

The 9V "stun gun" has such low power that it might stun a fly.
If you feel its output then you might jump then laugh.
A little 9V battery is too small to produce much power.

audioguru, actually that's entirely not true. If the transformers in that circuit are even halfway decent you could easily step 9 volts up WELL past the ability to kill. If you don't believe me.

Sorry for the plug for the website, that's how the link copied.
I wouldn't help the poster out with his circuit because if the transformers/coils aren't properly valued to current limit they could easily kill someone. Best left to people that actually know what they're doing.
