@Bytes
What kinda transformer are you using? I wanna take a look at driving one also.

@John, @Matt, here is the parts list;

Q1 MJL21194
Q2 MJL21194
Q3 MJL21194
Q4 MJL21194
Q5 MJL21194
Q6 MJL21194
Q7 MJL21194
Q8 MJL21194
R2 10k 1/2 Watt
R3 10k 1/4 Watt
R4 22k 1/4 Watt
R5 330R 1/4 Watt
R6 330R 1/4 Watt
SW1 Reset E28
T1 273-1365A (Radio Shack)
U1 PICAXE-18X
U3 LM7805
U-Q1 H11d1
U-Q3 H11d1
Z2 1N4744A

The output is AC so disregard the + - (carry over from other designs)

The input is 12V only AC or DC.

Add or Remove MJL's Q5,Q6,Q7,Q8 for increase or decrease in power rating.

The transformer noted here is 0.45A, so you'll need to subsitute with others as necessary.

Here is the code for the chip;
Main:

high 7
pause 10
low 7

high 6
pause 10
low 6


goto Main

Adjusting the delay down increases freq's.

Enjoy,

Jeff
