 Well it's quite noisy isn't it in the spark gap, it turns to the coil mode and obviously there's a lot can be done with tuning here because alright personally I've not got anything tuned look at my top load what's all that about I probably should take that off and it might be even better let me try it in a minute it's actually on 19 volts and the minutes I'm pushing it a little tiny bit and it's just set up the way it is so basically no maths and we get a little bit of something it'd be nice if it just like cracked out to the air by itself but I don't think this is going to do that I think you probably need a lot more power I've seen some of the chaps circuits that they've got on the internet and they look a lot more a lot more substantial in this little thing but as you can see you know and I've not even put two coils on there there is it does actually work a bit better with the two coils than what it did because the first you know like the first little bit of this you got to see it was on 12 volts with just one coil and then it went to 18 volts with one coil and then when it got a bit better um we got the two coils to our volts but I can't hold this and apply the power with the ability to quickly whip it off and hold it near the screwdriver at the same time so I have to balance the camera hold a little until I'm here and just do it all that time just do it one more little time and then I'm just gonna sort of like so I don't really expect to get too much out of this it didn't say that you're gonna get like massive massive output so let's give it a little one more little go so watch your ears you know turn the volume down whatever you're doing to protect your ears especially those with headphones on like this is gonna be a 90 yeah that's not bad I suppose well I'm not gonna turn the power up anymore because even though nothing's really hot or anything but like you said it's gonna run for a few seconds and I wouldn't suppose this would last very long if it tried to run it too long I don't have anything else I can use as a top load and I'm sure it'll probably be better if I had something better on top okay to change this round a bit and just see if it makes any difference maybe put two of these on like this and just see can you still see that yeah let's see what it's like without that bitumen but it's just noisy isn't it's very noisy very noisy oh I know I can do it I'll put it I'm sure this is what I want people to do that big let's try this I don't know if it's gonna do any good whatsoever but it'll probably make an interesting sound it's very sparky anyway that actually is a little bit better isn't it so probably gonna probably be yeah I'm pretty sure that the top loaders have quite a lot to do with it and maybe I could try different capacitors as well I do have I've got nothing you know that's that's that these are the chunkiest ones and the most power I'm able to deal with so but that was worth playing around with it seems to you know do a little bit that's quite good should I show you why you should be careful with these capacitors there's my big screwdriver it's just connected to ground I'm gonna short out the terminals on this baby okay frightens me every time and I know what's gonna happen
