am i gonna go grab that quartz ball and my horns ? 

lol

APPLE BOTTOM JEANS BOOTS WITH THE FUR!

: ) 

reason i gave her that rock .... 

! 

momma got cancer!

hummmmm!

ist!

grow light pics

This is like a joule thief circuit with only one end of the trigger coil back to the transistor base.
The other free end of the trigger coil is were the HV comes out.

Here is a video of it running off a cell phone charger using one AA battery.

And here is the circuit I'm using.

@slayer

Fantastic vid as usual.  I have a question though, does your A board have doides (AV plug)?

[slayer007]

No in the video there is no AV plug on the Bread board.The AV plug is on the led board.
I just showed it in the circuit so other people would know how the AV plug would go.

Right now I'm trying differant coil setups.And it seems to work great with more than one L1 coil inside each other.

Here is another short video just trying differant coil setups.
In the video I have another coil inside the bigger coil thats also going to the transistors base.(I would like to add one more)
I'm also using two transistors in parallel an 2n2222 and a MPSA06.
I also shrunk the L2 coil down a little so its more focused on the L1 coil.
At the begining of the video it's only using one AA battery then I add one more for two AA batteries.
It can also be more adjusted by moving the second L1 coil in and out of the big one.

Something else to try is a 10 k pot instead of the 1 k resistor for finer tuning.
