Thanks Mads! Sorry I haven't updated the project this days. I'm studying for some mid term tests and I haven't got the 25mm wire yet. I'm going to try and build a wider coil with the wire that I currently have, and test it in one of the uni's electronics labs, and try to compare it to the one using 25 mm wire. Btw, i have not posted the circuit schematic.
Question: will 1uF be enough, or shall I get a capacitor with a higher C?

Hello! Well. as the title says I'm trying to build my first tesla coil. I'm a begginer in electronics and this is my first project.
I'm trying to build it following this video's steps: />The tools and parts that I have consist of a multimeter (with which I do all of my measurements) and all the parts listed in the video, with some differences my mosfet transistor is an IRPF360 (instead of an IRPF260n) and coil was made with 1.31 mm^2 enameled wire.
I have not been able to generate a spark (and as there is a strong magnetic field generated when the coil is powered on, I can't take any measurements with it operating). And I have a few quetions and concerns.
Should the diameter of the pvc pipe compulsorily be 3cm? My secondary coil was wound in a 1,5 cm pipe, it has aprox 500 turns and it goes over itself (I am a bit worried about this, though, I have not found found any info that says this affects the correct operation of the coil) something that could be of importance is that the inductance of the coil is 1.4mH.
The sources I have are a 19.5 V 2.5A charger from a laptop and an ac converter from an old printer that outputs 24V but only 0.8 A.
I'd greatly appreciate if somebody has some opinion to share or some info/link from wich I can get any answers.
Pd.: pls forgive my English, I'm from Uruguay and we speak spanish here, so if I don't use technical terms, that's the reason why.
