I've been working for my thesis with Kirlian photography, researching and playing around with every single idea I found on the internet. Most of them required manual switching, 555 circuits or expensive pulse modulators, so I decided to try my own version and design a circuit driven by the Arduino. This schematic can be used in many projects that need pulse modulators and high voltage, be creative and enjoy!
Warning: This is a high voltage project. If you have no experience in this field please don't underestimate it. If you have heart problems, health issues or are pregnant don't try it!!!
I am not responsible for any incident or accident that might happen while you build this circuit. Please note that you should not have any problems if you follow this simple rules, but always be careful.
VIP Safety Rules:
-Wear rubber gloves
-Work with the adapter and battery unplugged at all time.
Don't place your finger on the discharge plate unless you are:
-Insulated from ground (sneakers or any insulating material)
-Tested the device on a ground object
Step 1: Main Schematic
This is the basic schematic, please take a second to understand it before we proceed. I designed it in illustrator because I am a visual designer and can't stand the way schematics look! hopefully you'll understand it better too.
To introduce yourself into the Kirlian concept you just need to know that it's a high voltage low current circuit that releases a discharge to an object or subject when this one is connected to ground. In this case there is a main input that gets released to a transformer and then converted into high voltage. Because I took the switch that controlled this input and the capacitors that retained them out of the schematic we will replace that part with a relay (let's say is a switch that can open and close depending on what we tell it).
A basic Kirlian circuit needs to work with an automatic pulse modulator that it's constantly feeding and releasing electrical juice. As humans we don't have the ability to turn a switch on an off that fast, so here is were the Arduino comes; It feeds the relay with a controlled pulse telling it to open or close whenever we want.
