hi uh.. again i guess. I get your point but i still need to see the video to make sure that the instructions were correct or not. Well but anyways did you still try increasing the no. of coils in the primary coil (just to see what happens, you know :p)
Um.. hi so, I am not in a place to say anything as I haven't made it myself as of now but from what I can see, the your primary coil has around two coils try increasing those as this instructable also recommends at least eight coils for 18V of power supply so by doing the math the least no. of coils in yours (if the power supply really is only 9V) should be four. But you can try increasing (or decreasing )the no. of coils even further until it's working alright.*Oh and yeah I kinda don't know why I wrote decreasing the no. of coils but you can try that too right :)
