Hello everyone, this is project How-ToDo. Since some of you asked to show in detail my variable frequency arduino generator for high voltage power supply, here it is.
Hello everybody, how do you do? This is project How-ToDo, my name is Konstantin and today I’ll make device for Kirlian photography. First I have to say this effect has nothing to do with photographing the aura, karma and anything like that, and the effect is exhaustively explained by physics. Second – we need high voltage for this device, and it’s could be dangerous if you don’t know what you doing, be careful! Actually this effect is basically just a nice visualization of corona discharge. You connect high voltage to the object and to the transparent electrode, usually it looks like two glass sheets and salt water between them, but because it’s kind of difficult to build, especially neat and without bubbles, I will use a slightly simplified design.
Hello! Today I’m going to show you how I build a Tesla coil! Probably you may know this device from computer games, movies or some “music tesla show” whatever they call it. If we ignore the mystique around the Tesla coils, it’s just a high-voltage resonance transformer working without a core. So as not to get bored from theory let’s jump to practice.
