 Okay I've made a couple of changes to the circuit, I've put an IRF, IRPF, I can't remember IRF 260N in, I've got a 1600 volt, I think it's 0.33 microfarad between this side of the primary. And the positive side of the input for the MOSFET. I've also put an electrolytic on the power rail, and I've put two diodes in, coming out of pin 3. One going to the negative, they're both reversed, polaritised. One going to the negative rail and one going to the positive rail. And that's just to try and keep the rail voltage where it is. Okay, this is going to be very, very quick, it's just to show there's a, I put a fan here, just to blow on this. Because it does get hot pretty quick, because that heatsink is tinsy tiny really for this situation. It would really need something much bigger, but I've done with playing with this now pretty much. I just wanted to just show you this last little bit, a slightly higher voltage. So, here we go. Like I said, it's going to be pretty quick in this video, just because, just because I don't want to kill anything. It's been a great little experience doing this or playing around. Now I've put another capacitor in as well. Even though I've got a capacitor, I've got a 5.6. I've got a 1.9 farad there. Oh, good to believe, I've got 2.1.9 farads in. Even though I've got 2.1.9 farads, I've just been playing around and it just seems to give me a better output and a bit of adjustability. So that got worn pretty quick. Cheers watching, guys.
